In the following, a plurality of embodiments of the present invention will be disclosed in the drawings. For the sake of clarity, many practical details will be explained in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

First embodiment

1 is a block diagram showing a digital photography system 100 in accordance with a first embodiment of the present invention. As shown in FIG. 1 , the digital camera system 100 includes a camera module 110 , a computing module 120 , a control unit 130 , and a fill light module 140 . The camera module 110 is configured to capture an image of a scene being photographed. The scene to be photographed includes a plurality of different positions, such as objects, objects, and/or objects within the scene being photographed. The fill light module 140 includes a light source 150 and an optical guide assembly 160. The light source 150 includes a plurality of light emitting elements 151. These light emitting elements 151 are arranged in an array of light. These light-emitting elements 151 are, for example, light-emitting diodes or laser diodes for emitting light having a main light-emitting axis. The optical guiding component 160 covers the light source 150 for receiving the light generated by the light source 150 and changing the traveling direction of the light (the main light output axis), the fill light depth (ie, the depth of field), or both, to generate the fill light to the received light. Shoot different specific locations in the scene. The computing module 120 is electrically connected to the camera module 110 for respectively obtaining position information of at least two locations within the captured scene. The location information is, for example, the focal length of the positions relative to the camera module 110, or the azimuth of the positions relative to the camera module 110, and the like. The control unit 130 is electrically connected to the fill light module 140 and the computing module 120 to issue The control signal driving fill light module 140 provides complementary light to the locations, wherein the light emitting elements 151 are enabled or disabled according to the control signal.

Thus, as shown in FIG. 1 , when the camera module 110 is aligned with the captured scene and at least two locations are selected manually or by software, the computing module 120 obtains location information of the locations within the captured scene. Then, when the camera module 110 captures a single image for the captured scene, the control unit 130 drives the fill light module 140 to provide fill light according to the position information of the positions, so that the fill light can be directed to different positions to provide stereo compensation. The light is used to solve the problem that the different areas in the scene are obviously unevenly displayed, thereby providing bright and clear images.

2A to 2C are schematic diagrams showing the filling of the different positions S11 to S33 of the captured scenes P1 to P3 by the light filling module 140 of the first embodiment. The above-mentioned fill light module is not limited to providing stereo fill light to these positions in different directions and/or different distances in the captured scene. For example, in the captured scene P1 shown in FIG. 2A, the first position S11 and the second position S12 in the captured scene P1 are not in the same focal plane compared to the fill light module 140, and the first The position S11 is closer to the fill light module 140 than the second position S12. Therefore, when the camera module 110 captures a single image of the captured scene P1, the fill light module 140 can provide the complementary light L11 and L12 of different luminous intensity according to the position information of the first position S11 and the second position S12. The first position S11 and the second position S12 are used to uniformize the degree of light exposure of different distances in the captured scene P1.

As shown in Figure 2B, the captured scene shown in Figure 2B In P2, compared with the fill light module 140, the first position S21 and the second position S22 are in the same focal plane, and the first position S21 and the second position S22 have different azimuth angles respectively. In other words, the distance from the first position S21 to the fill light module 140 is the same as the distance from the second position S22 to the fill light module 140. Therefore, when the camera module 110 captures a single image for the captured scene P2, the fill light module 140 can provide different traveling directions according to the position information of the first position S21 and the second position S22 in the captured scene P2. The fill light L21, L22 is to the first position S21 and the second position S22 to uniformize the degree of light exposure in different directions in the captured scene P2.

In addition, in the captured scene P3 shown in FIG. 2C, in addition to the first position S31 and the second position S32, there is a third position S33, compared to the fill light module 140, the first position S31 and the The two positions S32 are in the same focal plane. Compared with the fill light module 140, the first position S31 and the third position S33 are not in the same focal plane, and the first position S31 is closer to the fill light module 140 than the third position S33. Therefore, when the camera module 110 captures a single image for the captured scene P3, the fill light module 140 respectively provides different illuminations according to the position information in the captured scene P3 from the first position S31 to the third position S33. The fill light L31~L33 of the intensity and the traveling direction is from the first position S31 to the third position S33 to uniformize the degree of light exposure of different orientations and distances in the captured scene P3.

However, the above description is by way of example only and not as a limitation of the invention. Those having ordinary knowledge in the technical field to which the present invention pertains should also allow a greater number of positions in the captured scene to be filled with light depending on actual needs. In addition, digital photography systems such as cell phones, video cameras, driving recorders or notebooks Computers, etc., for example, for digital photography systems for vehicles, have a camera module for capturing road conditions images and a fill light module for supplementing light at specific locations in the road image. However, the present invention is not limited to the type of digital photography system.

It should be understood that although the fill light module provides stereoscopic fill light to the captured scene when the image capture module captures the image, the present invention is not limited to the light-emitting sequence of the light-emitting elements, and is generally in the technical field of the present invention. Knowledge workers should, depending on actual needs, allow these illuminating elements to illuminate simultaneously or sequentially.

However, the present invention is not limited thereto, and the above-mentioned light source may also have only a single light-emitting element (such as a light-emitting diode or a cold-light tube), and provide different light-emitting intensity or/or light-filling direction to the traveling direction through the action of the optical guiding component. Choose a location.

Second embodiment

FIG. 3 is a block diagram showing a digital photography system 300 in accordance with a second embodiment of the present invention. 4A to 4C are schematic diagrams showing the fill light module 340 of the second embodiment providing complementary light to different positions S41 to S43 of the captured scene. As shown in FIG. 3 , the digital imaging system 300 of the second embodiment is substantially the same as the digital imaging system 100 of the first embodiment, and also has a camera module 310 , a computing module 320 , a control unit 330 , and a fill light module 340 . In the second embodiment, the optical guiding component 360 further includes a driving circuit 370 and an electrically controlled focusing lens group 380. The driving circuit 370 is electrically connected to the electronically controlled focusing lens group 380 and the control unit 330 for changing the focal length of the electronically controlled focusing lens group 380 to adjust the advancement of the complementary light. Direction or / and fill light depth (ie depth of field). The electronically controlled focus lens group includes a plurality of liquid lenses 360A, each of which is coupled to one of the light emitting elements 351.

In operation, as shown in FIGS. 4A and 4B, by changing the hydraulic pressure in the liquid lens 360A, the outer shape of the lens liquid surface of the liquid lens 360A is changed, so that the liquid surfaces of the liquid lenses 360A can respectively guide the light-emitting elements 351. The direction of travel of the main light exiting axis of the light, that is, different liquid lenses 360A respectively generate different focal lengths, changing the original light collecting points of the main light exiting axes of the light, and then respectively converting them to be collected to the same or/and different focal planes The position of the light from S41 to S42. In this way, since the liquid lens 360A has the characteristics of dynamically adjusting the fill focus, dynamically adjusting the traveling direction, and both, the control unit 330 can make up the position according to the position information of the positions S41 to S42 in the captured scenes P4 and P5. The light module 340 dynamically adjusts the fill fill depth (ie, depth of field) and/or direction of travel of the fill light.

More specifically, as shown in FIGS. 4A and 4B, each liquid lens 360A includes a receiving portion 361, an insulating liquid 363 (such as eucalyptus oil), and at least one working liquid 364 (such as an organic electrolyte or pure water). And at least one electrode 366. Working fluid 364 contains a plurality of liquid molecules (not shown). The housing portion 361 defines a closed space 362. Electrode 366 is electrically coupled to working fluid 364 and drive circuit 370. The working liquid 364 and the insulating liquid 363 are mutually exclusive, and both are located in the closed space 362, and a boundary curved surface 365 is formed between the working liquid 364 and the insulating liquid 363. This boundary surface 365 is the above-mentioned lens liquid level. Thus, when the control unit 330 drives the electrodes 366 of each liquid lens 360A through the driving circuit 370, the electrodes 366 of each liquid lens 360A are The working liquid 364 is biased such that the lens liquid level of each working liquid 364 is respectively deformed into a lens surface, such as a concave lens surface or a convex lens surface, to adjust the complementary light to be different in the captured scenes P4 and P5, respectively. Position S41~S42.

It should be understood that the fill light module 340 of the second embodiment can not only provide complementary light to different positions at different distances, as shown in FIG. 4C, by changing the lens liquid level of a certain working liquid 364 (demarcation surface 365). For the asymmetrical lens surface, the fill light module 340 of the second embodiment can also provide a complementary light to the position S43 at the offset in the captured scene P6, that is, the position of the fill light can be turned to a specific position. So that these fill light are collected to a position S43 of a specific orientation.

In addition, in addition to the focal length control of the liquid lens 360A, the control unit 330 can also match the position information of the positions S41 to S43 in the captured scenes P4 to P6 to control the respective luminous intensities of the respective light-emitting elements 351 to enhance the fill light depth. (ie depth of field) control.

It should be understood that, in other embodiments, a plurality of liquid crystal lenses may be combined into a lens surface, and the lens surfaces are optically coupled to the light emitting array to control the traveling direction of the fill light or/and the fill light depth (ie, the depth of field). . The structure of each of these liquid lenses is similar to that of the above single liquid lens, and therefore will not be described again.

Third embodiment

FIG. 5 is a block diagram showing a digital photography system 500 in accordance with a third embodiment of the present invention. 6A to 6B show the third implementation The fill light module 540 of the mode provides a schematic diagram of supplemental light to different positions S61 to S63 of the captured scene P7. As shown in FIG. 5 , the digital imaging system 500 of the third embodiment is substantially the same as the digital imaging system 100 of the first embodiment, and also has a camera module 510 , a computing module 520 , a control unit 530 , and a fill light module 540 . Further, the optical guiding component 560 of the present embodiment includes a driving circuit 570 and an electrically controlled focusing lens group 580. The driving circuit 570 is electrically connected to the electronically controlled focusing lens group 580 and the control unit 530 for changing the focal length of the electronically controlled focusing lens group 580 to adjust the traveling direction of the complementary light or the fill light depth (ie, the depth of field). . The electronically controlled focus lens group 580 includes a single liquid crystal lens 560A coupled to the light-emitting elements 551 of the light source 550 and covering the light-emitting side of the light-emitting elements 551.

As shown in FIGS. 6A and 6B, the liquid crystal lens 560A includes two light-transmitting plates 561, a plurality of liquid crystal molecules 563, and a plurality of transparent electrodes 564. After the light transmissive plates 561 are covered with each other, a closed space 562 is defined therein. These liquid crystal molecules 563 are distributed in the enclosed space 562. These transparent electrodes 564 electrically connect the liquid crystal molecules 563 and the driving circuit 570, respectively. In this manner, when the control unit 530 sends a control signal to drive the transparent electrode 564 through the driving circuit 570, the transparent electrode 564 biases the liquid crystal molecules 563, so that the liquid crystal molecules 563 rotate in the closed space 562, and respectively Adjusting these fill light is collected in the position S61~S63 where the distance is different or/and the orientation is different in the shooting scene P7.

As shown in FIG. 6B, more specifically, when the left and right positions S61 and S62 are filled with light, the respective respective rotation directions of the liquid crystal molecules 563 are changed by the respective rotation directions of the liquid crystal molecules 563, thereby changing the respective light guiding directions of the liquid crystal molecules 563. The liquid crystal molecules 563 can respectively guide the traveling direction of the main light-emitting axis of the light of the light-emitting element 551, thereby changing the original light collecting points of the main light-emitting axis of the light of the light-emitting element 551, and then converting them to the left and right sides respectively. Position S61~S62 fill light.

In addition, when the light is filled in the middle position S63, the liquid crystal molecules 563 on the left and right sides of the liquid crystal lens 560A are rotated by a different amplitude than the liquid crystal molecules 563 in the middle of the liquid crystal lens 560A, so that the light filling module of the third embodiment is made. It is also possible to provide a fill light to the remote position S63, that is, the fill light module of the third embodiment can dynamically adjust the fill light depth (ie, the depth of field) of the fill light.

Thus, since the liquid crystal lens 560A has the characteristics of dynamically adjusting the fill focus, dynamically adjusting the traveling direction, and both, the control unit 530 can make the fill mode according to the position information of the positions S61 to S63 in the captured scene P7. The group arbitrarily adjusts the fill fill depth (ie depth of field) and/or the direction of travel.

In addition, in addition to controlling the fill depth (ie, depth of field) of the light-emitting element 551 in conjunction with the liquid crystal molecules 563, the control unit 530 can also control the positional information of the positions S61 to S63 in the captured scene P7 to control the respective light-emitting elements 551. Intensity to enhance the control of fill light depth (ie depth of field).

It should be understood that the optical guiding component of the fill light module of the third embodiment may also be a plurality of liquid crystal lenses. Each of the liquid crystal lenses is coupled to each of the light emitting elements to independently control the traveling direction of the complementary light or/and the fill light depth (ie, the depth of field) of the respective light emitting elements. The structure of these liquid crystal lenses is similar to that of the above single liquid crystal lens, and therefore will not be described again.

However, the present invention is not limited thereto, and the above light source may also have only There is a single illuminating element that provides a different illuminance or/and a fill direction to the selected position through the action of the optical guiding assembly.

Fourth embodiment

FIG. 7 is a block diagram showing a digital photography system 700 in accordance with a fourth embodiment of the present invention. FIG. 8 is a top view of the fill light module 740 of the fourth embodiment. As shown in FIGS. 7 and 8, the digital imaging system 700 of the fourth embodiment is substantially the same as the digital imaging system 100 of the first embodiment, and also has a camera module 710, a calculation module 720, a control unit 730, and a supplement. Light module 740. In a fourth embodiment, still further, the optical guiding assembly 760 includes a plurality of solid state lenses 760A. Each of the solid-state lenses 760A is coupled to the light-emitting elements 751 one by one and covers the light-emitting side of the light-emitting elements 751.

More specifically, as shown in FIGS. 7 and 8, in the fourth embodiment, in the fourth embodiment, the light-emitting array 750A of the light source 750 further includes a substrate 755. The light-emitting elements 751 are electrically connected to the substrate 755, respectively. One side of the substrate 755 is divided into a left column region 754, a middle column region 752, and a right column region 753. The middle column region 752 is located between the left column region 754 and the right column region 753. The light emitting elements 751 are all distributed in the left column region 754. The middle row 752 and the right column area 753 are respectively set to fill light to the right, the middle, and the left of the photographed scene (not shown). These solid-state lenses 760A are a telephoto solid lens 761, a mid-focus solid lens 762, and a near-focus solid lens 763, respectively. Since the telephoto solid lens 761 is more capable of directing light to a position farther within the captured scene than the near focus solid lens 763, each of the telephoto solid lenses 762 is coupled. Each of the light-emitting elements 751 is capable of providing light filling to a position away from the fill light module 740 in the captured scene, and each light-emitting element 751 coupled to the near-focus solid-state lens 763 is close to the fill light module 740 in the captured scene. The position provides fill light. Similarly, each of the light-emitting elements 751 coupled to the mid-focus solid-state lens 762 can provide fill light to a position that is approximately intermediate distances within the scene being photographed. As such, the fill light module 740 of the fourth embodiment can provide stereo fill light to the positions of different depths of view in the captured scene each time.

Further, in order to allow the fill light module 740 to provide stereo fill light to the positions of the same and different focal planes in the captured scene, the telephoto solid lenses 761 are simultaneously distributed in the left column area 754 and the middle column of the light emitting array 750A. The region 752 and the right column region 753, the meso-solid lens 762 are simultaneously distributed in the left column region 754, the middle column region 752 and the right column region 753 of the light-emitting array 750A, and the near-focus solid-state lens 763 is simultaneously distributed on the left side of the light-emitting array 750A. Column area 754, middle column area 752 and right column area 753. Thus, any of the light-emitting elements 751 located in the left column region 754, the middle column region 752 or the right column region 753 of the light-emitting array 750A is guided by its solid-state lens 761, 762 or 763, and this light-emitting element 751 is directed to the left of the scene being photographed. The fill, the middle or the right provides fill light. Therefore, the fill light module 740 of the fourth embodiment can provide stereo fill light to positions in different orientations within the captured scene.

However, in this embodiment, the types of the light-emitting elements coupled with the far-, medium-, or near-focus solid-state lenses are the same. However, the present invention does not limit the types of the light-emitting elements coupled with the far-, medium-, or near-focus solid-state lenses. In other embodiments, the light-emitting element coupled with the telephoto solid lens may be changed to the light-emitting diode having a vertical structure according to actual needs. And illuminating the light-emitting element coupled to the near-focus solid-state lens to a light-emitting diode having a laterally structured wafer. Since the light-emitting diode system having the vertical structure wafer outputs the forward light, it is advantageous to provide the fill light to a position farther away from the fill light module in the captured scene.

However, the above description is by way of example only and not as a limitation of the invention. Those skilled in the art to which the present invention pertains may, depending on actual needs, allow these solid-state lenses to be only a combination of a tele-focus solid-state lens and a near-focus solid-state lens, while omitting the meso-solid lens.

As shown in FIG. 9, the digital photography system 900 of the fifth embodiment is substantially the same as the digital imaging system 100 of the first embodiment, and also has a camera module 910, a calculation module 920, a control unit 930, and a fill light module 940. . In the fifth embodiment, the optical guiding component 960 further includes a driving circuit 970, an electrically controlled focusing lens group 980 and a plurality of solid lens 960A. The electrically controlled focus lens group 980 includes a plurality of electrically controlled focus lenses 990. The driving circuit 970 is electrically connected to the electronically controlled focusing lens group 980 and the control unit 930 for changing the focal length of the electronically controlled focus lens 990 to adjust the traveling direction of the complementary light or the fill light depth (ie, the depth of field). The solid-state lens 960A and the electronically controlled focus lens 990 are respectively coupled to the light-emitting elements 951 of the light source 950 and cover the light-emitting side of the light-emitting elements 951. For example, in the present embodiment, these solid-state lenses 960A are a telephoto solid lens 961 and a near-focus solid lens 963, respectively.
