Referring to fig. 1-8, an aspect of the embodiment of the present invention relates to a shielding detection apparatus 30, which may be applied to an electronic device 2 to implement shielding detection of a specific area, for example, shielding detection of an area where a sensor, a display area, an indicator light, a microphone, etc. are located. Fig. 5 is a schematic diagram of the occlusion detection device 30 installed in the electronic device 2, referring to fig. 5, the occlusion detection device 30 may be disposed on a surface of the electronic device 2, for example, the electronic device 2 includes a device body 60 and a control circuit 40, the surface of the device body 60 has a light-permeable window 13, and the occlusion detection device 30 may implement optical signal acquisition and generate a corresponding light detection signal through the window 13. The control circuit 40 may include a processor and circuitry connected between the processor and the occlusion detection device 30 and other elements in the electronic device 2. Alternatively, the electrical connection between the occlusion detection device 30 and the processor, and between other elements in the electronic device 2 and the processor, may be realized using a flexible printed circuit board 35 (FPC). As shown in fig. 1, the control circuit 40 is electrically connected with the shielding detection device 30 and receives a signal of the shielding detection device 30 to determine the shielding state of the window 13, and can further control the electronic device 2 according to the shielding state of the window 13. The occluded state of the window 13 may include an occluded state and a non-occluded state.
In some application scenarios, it is necessary to use an indicator light to emit light to indicate a specific operating state of the electronic device 2 in the electronic device 2, so that a user or other personnel can observe the state of the electronic device 2. For example, some electronic devices 2 include a photographing component 20 and have an image photographing function, and the electronic device 2 indicates a photographing state of the electronic device 2 by emitting light through an indicator lamp in a state in which the image photographing function is enabled, so as to prompt surrounding persons that the electronic device 2 is photographing, and avoid unauthorized or other improper photographing actions by a photographer. In some cases, however, the user of the electronic apparatus 2 may inadvertently or intentionally block the emission area of the indication light, so that surrounding persons cannot know that the electronic apparatus 2 is in the shooting state by the indication light.
Referring to fig. 4 and 5, the occlusion detection device 30 of the embodiment of the present invention includes a housing 31, a sensor assembly 32, and a visible light source group 33. The sensor assembly 32 and the visible light source group 33 are respectively electrically connected with the control circuit 40, and the control circuit 40 can realize signal interaction with the sensor assembly 32 and the visible light source group 33. The housing 31 has a mounting cavity, and the surface of the housing 31 has a light-transmitting hole 311 communicating the outside with the mounting cavity, and the light-transmitting hole 311 may be provided on the window 13 or disposed opposite to the window 13. The sensor assembly 32 and the visible light source group 33 are disposed within the mounting cavity and aligned with the light transmitting aperture 311. The visible light source group 33 includes at least two visible light sources 331, and can emit indication light outwards through the light holes 311, wherein the indication light is visible light S1 for human eyes to observe. The visible light source 331 may be a Light Emitting Diode (LED) or other visible light source. In the activated state of the photographing assembly 20, the control circuit 40 can emit an indication light as an indication of the photographing state of the electronic device 2 by controlling the visible light source 331 of the shielding detection device 30.
In a more specific application scenario, referring to fig. 2 and 3, the electronic device 2 may be the smart glasses 1, and the device body 60 may be the glasses body 10. The glasses body 10 may include a frame 11 and legs 12, the legs 12 being provided at both ends of the frame 11, a front end of each of the legs 12 being connected to the frame 11, a rear end extending rearward, and lenses being provided in the frame 11. The smart glasses 1 further include a photographing assembly 20 mounted on the glasses body 10. The shooting assembly 20 is used for being controlled to acquire images in a preset direction of the intelligent glasses 1, and the control circuit 40 is electrically connected with the shooting assembly 20 and the shielding detection device 30 respectively. After the control circuit 40 controls the light source to emit the indication light in the photographing prompt mode, the indication light is emitted outwards through the light transmitting hole 311 and the window 13 of the glasses main body 10. Preferably, the direction of the indication light emitted through the window 13 and the shooting direction of the shooting assembly 20 are oriented in the same direction, for example, on the same side of the glasses main body 10, so as to ensure that the photographer can clearly see the indication light to know that he or she is being shot during the shooting process of the shooting assembly 20.
Depending on the actual application, the camera assembly 20 and the occlusion detection device 30 may be mounted on the frame 11 or the temple 12. In one embodiment, the camera assembly 20 and the occlusion detection device 30 may each be mounted to the frame 11. The mirror frame 11 has installation space, and installation space communicates with the mirror frame 11 surface through the mounting hole of seting up on the mirror frame 11, and shielding detection device 30 locates the installation space, and window 13 locates the mirror frame 11. The control circuit 40 may be provided in the temple 12, in the frame 11, or distributed in both the frame 11 and the temple 12. The control circuit 40 may include a processor and circuitry connected between the processor and the occlusion detection device 30, the camera assembly 20, and other elements in the smart glasses 1. Alternatively, the electrical connection between the occlusion detection device 30 and the processor, and between the camera assembly 20 and the processor, may be accomplished using a flexible printed circuit board 35 (FPC). The control circuit 40 may be provided in the temple 12, in the frame 11, or distributed in both the frame 11 and the temple 12. Preferably, the window 13 is hermetically installed with the installation hole, so that the intelligent glasses 1 are waterproof and dustproof.
The sensor assembly 32 includes an ambient light sensor 321, a proximity sensor 322, and an infrared light source 323, wherein the ambient light sensor 321 can detect ambient light entering the mounting cavity from the light-transmitting hole 311 to generate a first detection signal, the infrared light source 323 can emit infrared light S2 outwards through the light-transmitting hole 311, and the proximity sensor 322 can detect the infrared light S2 to generate a second detection signal. In some embodiments, the ambient light sensor 321, the proximity sensor 322, and the infrared light source 323 may be implemented as an integrated three-in-one sensor module, which is beneficial to improving the integration level of the occlusion detection assembly. Since the light entering the mounting cavity through the light transmitting hole 311 and reaching the sensor assembly 32 is affected when the obstacle 3 exists in front of the window 13, the detection value of the ambient light sensor 321 or the proximity sensor 322 is changed, the control circuit 40 may determine the shielding state of the window 13 according to at least one of the first detection signal and the second detection signal, and the determined shielding state of the window 13 may characterize whether the indication light emitting area is shielded. Thus, the shielding detection device 30 can realize both functions of indicating the operation state of the electronic apparatus 2 and shielding detection. In this case, the control circuit 40 may control the operation state of the photographing assembly 20 according to the blocking state of the window 13, for example, when the determined blocking state of the window 13 is the blocked state, the control circuit 40 may prevent photographing behavior not authorized by the photographer by controlling the photographing assembly 20 to be powered off or otherwise stop photographing. In addition, when it is determined that the shielding state of the window 13 is the shielded state, the user may be reminded to continue to use the shooting function by playing a prompt tone through a speaker provided on the electronic device 2 or displaying a prompt message to the user through the display assembly 50.
Fig. 5 schematically shows a schematic view of light reflection when the obstacle 3 is present in front of the window 13, wherein the dashed arrow line in the figure indicates the indicating light (visible light S1) emitted from the visible light source group 33, and the dashed double-dotted arrow line in the figure indicates the infrared light S2 emitted from the infrared light source 323. Referring to fig. 5, when the visible light source group 33 emits the indication light (visible light S1), if the window 13 is blocked by the obstacle 3, at least a portion of the indication light (visible light S1) will be reflected by the obstacle 3 to enter the installation cavity again and reach the ambient light sensor 321, and thus, when the window 13 is in the blocked state and in the non-blocked state, there is a difference in light reaching the ambient light sensor 321, resulting in a difference in the first detection signal. Thereby, the occlusion state of the window 13 can be determined from the first detection signal. To achieve more accurate ambient light detection, the first detection signal may be temperature compensated based on the ambient temperature. Generally, the luminous intensity of the LED and the sensitivity of the ambient light sensor 321 can be considered to be in a linear relationship within the temperature range of the use scene of the smart glasses 1, and the luminous intensity p=k×t+c corresponding to the first detection signal, where K is a temperature coefficient, T is an ambient temperature, and C is a temperature compensation curve of the visible light source group 33 (LED) and the ambient light sensor 321.
With continued reference to fig. 5, when the infrared light source 323 emits the infrared light S2, if the window 13 is blocked by the obstacle 3, at least a portion of the infrared light S2 will be reflected by the obstacle 3 to re-enter the mounting cavity and reach the proximity sensor 322, and thus, when the window 13 is in the blocked state and in the non-blocked state, there is a difference in the infrared light S2 reaching the proximity sensor 322, resulting in a difference in the second detection signal. Thereby, the occlusion state of the window 13 can be determined from the second detection signal. Preferably, the infrared light source 323 may be a Vertical-Cavity Surface emitting laser (Vertical-Cavity Surface-EMITTING LASER, VCSEL), and the wavelength of the output light beam is 940nm, and the wavelength of the output light beam is near infrared, so that the ambient light sensor 321 is insensitive to the wavelength band, and the first detection signal is not easily affected, thereby enhancing the interference resistance. The VCSEL has a beam direction emitted perpendicular to the chip surface, has a strong beam quality, has the advantages of low power consumption and fast response, and is suitable for use as the infrared light source 323 for proximity detection. The proximity sensor 322 may include an infrared light S2 receiver or other infrared light S2 sensitive element, and the detection range of the proximity sensor 322 is adapted to the wavelength band of the infrared light source 323.
Alternatively, the overlap ratio of the wavelength band of the light emitted from the visible light source group 33 and the detection range of the proximity sensor 322 is smaller than the first overlap ratio, and the overlap ratio of the wavelength band of the light emitted from the infrared light source 323 and the detection range of the ambient light sensor 321 is smaller than the second overlap ratio. By controlling the coincidence ratio of the indication light band with the detection range of the proximity sensor 322 and the coincidence ratio of the infrared light S2 band of the infrared light source 323 with the detection range of the ambient light sensor 321, the tamper resistance of the proximity sensor 322 and the ambient light sensor 321 can be enhanced. The specific values of the first and second degree of coincidence may be set according to the need for detection accuracy, and preferably the first and second degree of coincidence may be 0 or a smaller value close to 0.
Because the indication light and the infrared light S2 are emitted and the reflection light formed by the reflection of the indication light and the infrared light S2 against the obstacle 3 is incident to the sensor assembly 32 and needs to pass through the same light transmission hole 311, compared with the case that the light path of the indication light and the light path of the reflection light irradiation ambient light sensor 321 are set to be two completely separated light paths, the technical scheme of the embodiment of the invention can effectively avoid the problem that the detection value of the ambient light sensor 321 cannot be changed when only the indication light emitting area is blocked, thereby leading to the blocking detection failure.
In one example for comparison, only one visible light source 331 is provided at one side of the ambient light sensor 321, or a plurality of visible light sources 331 are provided at the same side of the ambient sensor, so that when the visible light source 331 emits light, the Field of View (FOV) of the ambient light sensor 321 is not symmetrical, causing an increase in error in light irradiated onto the ambient light sensor 321 in a specific direction.
Fig. 6 to 8 are schematic views of the light hole 311 as seen into the mounting cavity. In the embodiment of the present invention, referring to fig. 6 to 8, each visible light source 331 of the visible light source group 33 is disposed on the outer side of the sensor assembly 32 and located in different radial directions of the ambient light sensor 321, so that when the visible light source group 33 emits light, the ambient light sensor 321 has more uniform illumination in multiple angles, which enhances the accuracy of detection of the ambient light sensor 321, and thus can avoid the problem of increased error of illumination of the ambient light sensor 321 in a specific direction in the above comparative example. For example, the plurality of visible light sources 331 of the visible light source group 33 are arranged on the outer periphery of the ambient light sensor 321 in a centrosymmetric or mirror symmetrical manner, which can make the FOV of the ambient light sensor 321 more symmetrical. Further, the sensor assembly 32 may be located at a position corresponding to the center of the light hole 311, which is advantageous for making each area of the ambient light sensor 321 have a relatively uniform light receiving condition.
In some embodiments, referring to fig. 6 and 8, the visible light source group 33 may include an even number of visible light sources 331, the plurality of visible light sources 331 being disposed at the periphery of the ambient light sensor 321 in a mirror-symmetrical manner, and the symmetry plane being located at the position of the ambient light sensor 321. In one embodiment, referring to fig. 6, the visible light source group 33 includes four visible light sources 331, the four visible light sources 331 are disposed in four directions of up, down, left, and right of the ambient light sensor 321 in the figure, and positions of the visible light sources 331 on the left side and the right side are mirror symmetrical and symmetry planes are located at positions of the ambient light sensor 321, and positions of the visible light sources 331 on the upper side and the lower side are mirror symmetrical and symmetry planes are located at positions of the ambient light sensor 321.
In other embodiments, the plurality of visible light sources 331 of the visible light source group 33 are disposed on the outer periphery of the ambient light sensor 321 in a center-symmetrical manner. For example, referring to fig. 7, the visible light source group 33 includes three visible light sources 331, and the three visible light sources 331 are disposed around the outer circumference of the sensor assembly 32 and are distributed substantially in center symmetry with respect to the center of the ambient light sensor 321.
In some embodiments, referring to fig. 4 and 8, the occlusion detection device 30 may further include a light uniformizing device 34, where the light uniformizing device 34 is disposed on a side of the visible light source group 33 opposite to the light transmitting hole 311 and covers the visible light source group 33. The light homogenizing device 34 is an optical element for homogenizing light distribution, and the arrangement of the light homogenizing device 34 is beneficial to further improving the uniformity of the indication light, and can realize more uniform indication light under the condition of fewer visible light sources 331, thereby being beneficial to reducing the volume of the shielding detection device 30. The light homogenizing device 34 may employ a light homogenizing film, a microlens array, a diffraction optical element, or other kinds of light homogenizing devices 34. In the embodiment of the present invention, the light homogenizing device 34 may use a light homogenizing film, which is beneficial to reducing the cost and reducing the volume of the shielding detection device 30. The light homogenizing device 34 may shade the sensor assembly 32 or dodge the sensor assembly 32. In some embodiments, referring to fig. 8, the light homogenizing device 34 has a hollowed-out hole in the middle to expose the sensor component 32, which is beneficial to ensure the sensitivity of the ambient light sensor 321 and the proximity sensor 322.
In some embodiments, the sensor assembly 32 and the visible light source group 33 may be disposed on the same printed circuit board 35, which is not only beneficial to reduce the volume of the shielding detection device 30, but also facilitates ensuring the relative positions of the sensor assembly 32 and the visible light source group 33. The printed circuit board 35 may be a hard printed circuit board 35 or a flexible printed circuit board 35.
In some embodiments, referring to fig. 4 and 5, the occlusion detection device 30 further includes a light guide 36, the light guide 36 being disposed in the mounting cavity and in the light path between the light aperture 311 and the sensor assembly 32. The light guide 36 is an optical element for guiding a light propagation path by total reflection or scattering, and the light guide 36 may be made of a high light transmittance material, for example, PMMA, PC, glass, etc., which has a higher refractive index than the surrounding environment, and controls the light propagation path by a specific shape.
The shielding detection device 30 may be disposed near the photographing assembly 20, preferably, the shape of the light guide 36 and the selection of the type of the visible light source group 33 and the ambient light sensor 321 may be designed such that the angle of view of the indication light emitting window 13 is larger than the angle of view of the photographing assembly 20, and the angle of view of the ambient light sensor 321 is larger than the angle of view of the photographing assembly 20, so that the visible direction coverage area of the indication light is adapted to the photographing area of the photographing assembly 20.
In some application scenarios, the ambient light sensor 321 of the shielding detection device 30 may also be used to detect ambient light, implement multiplexing of functions, improve the utilization rate of the shielding detection device 30, and facilitate miniaturization of the electronic device 2. When the visible light source 331 does not emit light, the visible light S1 emitted from the window 13 and the light hole 311 to the ambient light sensor 321 is mainly ambient light, and the first detection signal of the ambient light sensor 321 may reflect the intensity of the ambient light. The control circuit 40 of the smart glasses 1 may determine the intensity of the ambient light according to the first detection signal, and perform corresponding control on the smart glasses 1 according to the determined intensity of the ambient light. Alternatively, as shown in fig. 3, the smart glasses 1 may further include a display assembly 50 for displaying an image, and the display assembly 50 may be disposed on the frame 11 and electrically connected with the control circuit 40. When the visible light source 331 does not emit light, the control circuit 40 determines an ambient light intensity state according to the first detection signal, and in a display state of the display assembly 50, the control circuit 40 adjusts the display luminance of the display assembly 50 according to the determined ambient light intensity state. When the intensity of the ambient light is increased, the display brightness of the display assembly 50 is controlled to be increased, and when the intensity of the ambient light is reduced, the display brightness of the display assembly 50 is controlled to be reduced, so that the display brightness of the display assembly 50 can be intelligently adjusted according to the change of the ambient light, and the visual effect of watching images by a user is improved. In some embodiments, display assembly 50 may comprise a micro-display, illumination system, waveguide, etc., and adjustment of display brightness may be accomplished by adjusting the waveguide, adjusting illumination system current, or other possible manners, as embodiments of the invention are not limited in this regard.
The smart glasses 1 in the embodiment of the present invention, the control circuit 40 may activate the photographing assembly 20 in response to the photographing request. The photographing request refers to a request for starting the photographing component 20 to perform image acquisition, and optionally, the user may initiate the photographing request by performing a predetermined operation (for example, clicking a button, a voice command, a gesture command, etc.) with respect to the smart glasses 1. The control circuit 40, upon receiving the photographing request, controls the photographing assembly 20 to start to perform photographing if other conditions for starting the photographing function are satisfied.
In one embodiment, the control circuit 40 may enter the occlusion detection mode when the camera assembly 20 is activated. When the occlusion detection mode is entered, the control circuit 40 controls the visible light source group 33 to emit an indication of the indication light to realize the shooting state. While the visible light source group 33 emits the indication light, the control circuit 40 may stop adjusting the display brightness of the display assembly 50 according to the first detection signal in the occlusion detection mode in an embodiment because the first detection signal may not accurately reflect the state of the ambient light due to the influence of the external obstacle 3 on the reflected light of the indication light.
In another embodiment, the control circuit 40 may also control the visible light source group 33 to emit light before the shooting assembly 20 is started after receiving the shooting request, and restart the shooting function of the shooting assembly 20 when the determined blocking state of the window 13 is a non-blocking state. When the photographing assembly 20 is dormant or powered off, the control circuit 40 may control the visible light source group 33 to stop emitting the indication light.
In some embodiments, when the occlusion detection mode is entered, the control circuit 40 controls the visible light source group 33 to emit the indication light, controls the infrared light source 323 to emit the infrared light S2, and determines the occlusion state of the window 13 according to the first detection signal of the ambient light sensor 321 and/or the second detection signal of the proximity sensor 322. Preferably, when either one of the first detection signal and the second detection signal satisfies a corresponding specific condition, it may be determined that the shielding state of the window 13 is shielded, whereby the sensitivity of shielding detection may be improved, while the problem that cannot be detected when the window 13 is shielded by using the obstacle 3 having high absorptivity to the visible light S1 and low absorptivity to the infrared light S2, or the obstacle 3 having high absorptivity to the infrared light S2 and low absorptivity to the visible light S1 may be avoided.
In some embodiments, the control circuit 40 may control the on/off of the visible light source group 33 in time sequence, that is, control the visible light source group 33 to alternately emit light and to turn off in a predetermined period. For example, each cycle includes a first period and a second period alternately arranged, and the control circuit 40 controls the light source to emit light in the first period and to extinguish in the second period. The duration of the second period may be a smaller value, and in this embodiment, the duration of the second period may be less than 0.1 seconds. The control circuit 40 determines an on-light intensity value and an off-light intensity value according to the first detection signal in accordance with the timing of the first period and the second period. The on light intensity value corresponds to the light intensity value when the visible light source group 33 emits light, and the off light intensity value corresponds to the light intensity value when the visible light source group 33 extinguishes. When the obstacle 3 exists in front of the window 13, the obstacle 3 reflects the indication light, so that the first detection signal has a certain difference between the light emission and extinction of the visible light source group 33, and the shielding state of the window 13 can be determined according to the first light intensity difference.
In one embodiment, the occlusion state of window 13 may be determined to be occluded when the first light intensity difference is greater than a first threshold. The first threshold may be a larger value, that is, when the difference between the open light intensity value and the reference light intensity value is larger, it indicates that the window 13 may be preceded by a shade that shades the indication light and forms a reflected light with a larger light intensity, so that it may be determined that the shielding state of the window 13 is a blocked state. The control circuit 40 may further determine that the shielding state of the window 13 is shielded when the light intensity value corresponding to the second detection signal is greater than the second threshold value.
In some embodiments, the shielding state of the window 13 may also be determined according to the light intensity value corresponding to the first detection signal of the ambient light sensor 321 in the state that the visible light source group 33 emits the indication light. When the first detection signal is greater than the third threshold or less than a fourth threshold, the occlusion state of the window 13 is determined to be occluded, wherein the fourth threshold is less than the third threshold. The third threshold may be a larger value, that is, when the first detection signal is larger, it indicates that there may be a shielding object in front of the window 13 to block the indication light and form the reflected light with a larger light intensity, so that it may be determined that the shielding state of the window 13 is the blocked state. Since a part of the ambient light is blocked when the obstacle 3 is present before the window 13, so that the incident ambient light is also reduced, it may be possible that the obstacle 3 having a high absorptivity of the visible light S1 is present when the first detection signal is smaller than the fourth threshold, and thus it may be determined that the blocked state of the window 13 is the blocked state.
According to the intelligent glasses 1, the shielding detection device 30 and the electronic equipment 2, the sensor assembly 32 is arranged in the mounting cavity of the shell 31 and is aligned with the light transmitting hole 311 of the shell 31, the sensor assembly 32 comprises the ambient light sensor 321, the proximity sensor 322 and the infrared light source 323, at least two visible light sources 331 are arranged in different radial directions of the ambient light sensor 321, the control circuit 40 controls the visible light source group 33 to emit indication light, the infrared light source 323 is controlled to emit infrared light S2, the shielding state of the window 13 is determined according to at least one of a first detection signal of the ambient light sensor 321 and a second detection signal of the proximity sensor 322, the emergent area of the indication light and the light entering area of shielding detection share the same light transmitting hole 311, the condition that shielding detection fails when only the emergent area of the indication light is shielded is avoided, and the view angle of the ambient light sensor 321 is symmetrical in all directions due to the position setting of the visible light sources 331, and the shielding detection sensitivity and accuracy are facilitated to be improved.
