Description

Electronic device and operating method for electronic device

The present disclosure relates to a device and an operating method of the device, and in particular to an electronic device and an operating method for the electronic device.

Generally speaking, an electronic device is equipped with one or more image acquisition units. Due to differences in process, batch number or manufacturer, the characteristics of each image acquisition unit are also different. In order to enable each image acquisition unit to provide display data as similar as possible when capturing the same image, the operating parameters corresponding to the image acquisition unit can be recorded in the electronic device.

However, when an error occurs in the operating parameter (e.g., the content of the operating parameter is incorrect or the operating parameter does not exist), the electronic device cannot receive the display data of the image capture unit. If the electronic device includes a display, the display cannot present an image according to the display data, thereby displaying an abnormal display result such as a black screen.

Therefore, how to enable the electronic device to receive the display data of the image capture unit when the operating parameters are wrong is one of the research focuses of the technical personnel in this field.

The present disclosure provides an electronic device and an operating method for the electronic device, which can enable the electronic device to receive display data from an image capture unit when an operating parameter error occurs.

The electronic device disclosed herein includes at least one image capture unit, a memory, and an image processor. The at least one image capture unit includes a first image capture unit. The memory stores preset parameters and at least one operating parameter corresponding to the at least one image capture unit. The image processor is coupled to the at least one image capture unit and the memory. The image processor responds to a driving signal to read a first operating parameter corresponding to the first image capture unit, and judges the first operating parameter. When the first operating parameter is correct, the image processor uses the first operating parameter to control the first image capture unit to receive the first image data from the first image capture unit, and uses the first operating parameter to convert the first image data into first display data. When the first operating parameter is erroneous, the image processor receives the second image data from one of the at least one image capturing units using the preset parameter, and converts the second image data into second display data using the preset parameter.

The disclosed operating method is used to operate an electronic device. The electronic device includes at least one image capture unit and a memory. The at least one image capture unit includes a first image capture unit. The operating method includes: storing a preset parameter and at least one operating parameter corresponding to the at least one image capture unit in a memory; reading a first operating parameter corresponding to the first image capture unit in response to a driving signal, and judging the first operating parameter; when the first operating parameter is correct, using the first operating parameter to control the first image capture unit to receive first image data from the first image capture unit, and using the first operating parameter to convert the first image data into first display data; and when the first operating parameter is erroneous, using the preset parameter to receive second image data from one of the at least one image capture units, and using the preset parameter to convert the second image data into second display data.

Based on the above, when the first operating parameter is wrong, the electronic device uses the preset parameter to receive the second image data from one of the at least one image capture unit, and uses the preset parameter to convert the second image data into the second display data. In this way, when the operating parameter is wrong, the electronic device can still receive the display data.

Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. When the same element symbols appear in different drawings, they will be regarded as the same or similar elements. These embodiments are only part of the present disclosure and do not disclose all possible implementations of the present disclosure. More precisely, these embodiments are only examples within the scope of the patent application of the present disclosure.

Please refer to FIG1, which is a schematic diagram of an electronic device according to an embodiment of the present disclosure. In this embodiment, the electronic device 100 includes image capture units 110_1, 110_2, a memory 120, and an image processor 130. The memory 120 stores a preset parameter PRAD and operation parameters PRA1, PRA2 corresponding to the image capture units 110_1, 110_2.

For example, the operating parameter PRA1 is used for the image capture unit 110_1. The operating parameter PRA2 is used for the image capture unit 110_2. For example, when capturing the same image, the image data DIMG1 provided by the image capture unit 110_1 based on the operating parameter PRA1 is similar to the image data DIMG2 provided by the image capture unit 110_2 based on the operating parameter PRA2. In addition, the preset parameter PRAD is applicable to the image capture units 110_1 and 110_2.

In this embodiment, the image processor 130 is coupled to the image capture units 110_1, 110_2 and the memory 120. The image processor 130 responds to the driving signal SD to read the operating parameter PRA1 corresponding to the image capture unit 110_1 or the operating parameter PRA2 corresponding to the image capture unit 110_2. The image processor 130 determines the received operating parameter (i.e., one of the operating parameter PRA1 and the operating parameter PRA2).

For example, the driving signal SD is a signal for instructing the electronic device 100 to drive the image capture unit 110_1. The image processor 130 reads the operating parameter PRA1 in response to the driving signal SD. When the operating parameter PRA1 is correct, the image processor 130 uses the operating parameter PRA1 to control the image capture unit 110_1 to receive the image data DIMG1 from the image capture unit 110_1, and uses the operating parameter PRA1 to convert the image data DIMG1 into the display data DDP1. On the other hand, when the operating parameter PRA1 is erroneous, the image processor 130 receives the image data from one of the image capture units 110_1 and 110_2 using the default parameter PRAD, and converts the image data into display data using the default parameter PRAD.

For further example, when the operating parameter PRA1 is erroneous, the image processor 130 receives the image data DIMGD1 from the image capture unit 110_1 using the preset parameter PRAD, and converts the image data DIMGD1 into display data D1 using the preset parameter PRAD. For another example, when the operating parameter PRA1 is erroneous, the image processor 130 receives the image data DIMGD2 from the image capture unit 110_2 using the preset parameter PRAD, and converts the image data DIMGD2 into display data D2 using the preset parameter PRAD. Based on the same preset parameter PRAD, the image capture units 110_1 and 110_2 can both provide the image data DIMGD1 and DIMGD2.

For example, the driving signal SD is a signal for instructing the electronic device 100 to drive the image capture unit 110_2. The image processor 130 reads the operating parameter PRA2 in response to the driving signal SD. When the operating parameter PRA2 is correct, the image processor 130 uses the operating parameter PRA2 to control the image capture unit 110_2 to receive the image data DIMG2 from the image capture unit 110_2, and uses the operating parameter PRA1 to convert the image data DIMG1 into the display data DDP1. On the other hand, when the operating parameter PRA2 is erroneous, the image processor 130 receives the image data from one of the image capture units 110_1 and 110_2 using the default parameter PRAD, and converts the image data into display data using the default parameter PRAD.

It is worth mentioning that when at least one of the operating parameters PRA1 and PRA2 is wrong, the electronic device 100 receives one of the image data DIMGD1 and DIMGD2 using the preset parameter PRAD, and converts one of the image data DIMGD1 and DIMGD2 into display data (i.e., display data D1 or display data D2) using the preset parameter PRAD. In this way, when at least one of the operating parameters PRA1 and PRA2 is wrong, the electronic device 100 can still receive one of the image data DIMGD1 and DIMGD2 and generate display data accordingly.

In this embodiment, the operating parameter PRA1 includes, for example, at least one of the name of the image capture unit 110_1, the white balance parameter corresponding to the image capture unit 110_1, the exposure parameter corresponding to the image capture unit 110_1, and the facial recognition parameter corresponding to the image capture unit 110_1. The operating parameter PRA2 includes, for example, at least one of the name of the image capture unit 110_2, the white balance parameter corresponding to the image capture unit 110_2, the exposure parameter corresponding to the image capture unit 110_2, and the facial recognition parameter corresponding to the image capture unit 110_2.

For example, the operating parameters PRA1 and PRA2 can be adjusted. After adjusting the operating parameters PRA1 and PRA2, the white balance result, exposure result or face recognition result of the display data DDP1 is similar to the white balance result, exposure result or face recognition result of the display data DDP2. Therefore, when the electronic device 100 controls a screen to play the display data DDP1 and DDP2 corresponding to the same captured image, the user cannot easily detect the display difference between the display data DDP1 and DDP2.

In this embodiment, the preset parameters PRAD include, for example, at least one of preset white balance parameters, preset exposure parameters, and preset face recognition parameters. For example, the preset white balance parameters may be between the white balance parameters corresponding to the image capture unit 110_1 and the white balance parameters corresponding to the image capture unit 110_2. The preset exposure parameters may be between the exposure parameters corresponding to the image capture unit 110_1 and the exposure parameters corresponding to the image capture unit 110_2. The preset face recognition parameters may be between the face recognition parameters corresponding to the image capture unit 110_1 and the face recognition parameters corresponding to the image capture unit 110_2. Therefore, the preset parameter PRAD is an operating parameter applicable to the image capture units 110_1 and 110_2.

In this embodiment, the memory 120 can be any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory, etc., which are memory elements known to those skilled in the art. The memory 120 includes a look-up table 121. The look-up table 121 records the preset parameter PRAD and the operating parameters PRA1 and PRA2.

In this embodiment, the image processor 130 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessor, digital signal processor (DSP), programmable controller, application specific integrated circuits (ASIC), programmable logic device (PLD) or other similar devices or a combination of these devices, which can load and execute computer programs.

For the sake of convenience, two image capture units 110_1 and 110_2 are used as examples in this embodiment. However, the present disclosure is not limited to the number of image capture units. The number of image capture units disclosed in this disclosure can be one or more. In this embodiment, the electronic device 100 can be, for example, a laptop, a desktop computer, a tablet computer, a display device, a smart phone, etc., which is equipped with or connected to at least one image capture unit.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a flow chart of an operation method according to an embodiment of the present disclosure. The operation method S100 is applicable to the electronic device 100. In this embodiment, the operation method S100 includes steps S110 to S150. In step S110, the preset parameter PRAD and the operation parameters PRA1 and PRA2 corresponding to the image capture units 110_1 and 110_2 are stored in the memory 120. In step S120, the image processor 130 responds to the drive signal SD to read the first operation parameter corresponding to the first image capture unit. For example, the drive signal SD is a signal used to instruct the electronic device 100 to drive the image capture unit 110_1. The first image capture unit is the image capture unit 110_1. The first operating parameter is the operating parameter PRA1. Therefore, the image processor 130 reads the operating parameter PRA1 stored in the memory 120 in response to the driving signal SD.

In step S130, the image processor 130 determines whether the operating parameter PRA1 is correct. In the present embodiment, the image processor 130 determines whether the content or syntax of the operating parameter PRA1 conforms to one of a plurality of preset contents or preset syntaxes. When the image processor 130 determines whether the content or syntax of the operating parameter PRA1 conforms to one of a plurality of preset contents or preset syntaxes, the image processor 130 determines that the operating parameter PRA1 is correct. Therefore, the image processor 130 uses the operating parameter PRA1 to control the image capture unit 110_1 in step S140 to receive the image data DIMG1 from the image capture unit 110_1, and uses the operating parameter PRA1 to convert the image data DIMG1 into the display data DDP1.

On the other hand, when the image processor 130 determines whether the content or syntax of the operating parameter PRA1 does not conform to any of the multiple preset contents or preset syntaxes, this means that the operating parameter PRA1 may be damaged, incorrectly implanted, or does not exist. Therefore, the image processor 130 determines that an error has occurred in the operating parameter PRA1. Therefore, the image processor 130 reads the preset parameter PRAD stored in the memory 120 in step S150, uses the preset parameter PRAD to receive the second image data (i.e., one of the image data DIMGD1, DIMGD2) from one of the image capture units 110_1, 110_2, and uses the preset parameter PRAD to convert the second image data into second display data (i.e., one of the display data D1, D2).

Please refer to FIG. 3, which is a schematic diagram of an electronic device according to an embodiment of the present disclosure. In this embodiment, the electronic device 200 includes image capture units 110_1, 110_2, a memory 120, an image processor 130, and a display 240. The memory 120 stores a preset parameter PRAD and operating parameters PRA1, PRA2. The image processor 130 is coupled to the image capture units 110_1, 110_2, the memory 120, and the display 240. The image processor 130 responds to the drive signal SD to read the operating parameter PRA1 corresponding to the image capture unit 110_1 or the operating parameter PRA2 corresponding to the image capture unit 110_2. The image processor 130 determines the received operating parameter (ie, one of the operating parameter PRA1 and the operating parameter PRA2).

Taking the operation parameter PRA1 as an example, when the operation parameter PRA1 is correct, the image processor 130 uses the operation parameter PRA1 to control the image capture unit 110_1 to receive the image data DIMG1 from the image capture unit 110_1, and uses the operation parameter PRA1 to convert the image data DIMG1 into the display data DDP1. In addition, when the operation parameter PRA1 is correct, the image processor 130 uses the display data DDP1 to control the display 240.

On the other hand, when the operating parameter PRA1 is erroneous, the image processor 130 receives the image data DIMGD1 from the image capture unit 110_1 using the preset parameter PRAD, and converts the image data DIMGD1 into display data D1 using the preset parameter PRAD. In addition, the image processor 130 also uses the display data D1 to control the display 240. In one embodiment, when the operating parameter PRA1 is erroneous, the image processor 130 may also receive the image data DIMGD2 from the image capture unit 110_2 using the preset parameter PRAD, and convert the image data DIMGD2 into display data D2 using the preset parameter PRAD. In addition, when the operating parameter PRA1 is erroneous, the image processor 130 also uses the display data D2 to control the display 240.

As mentioned above, the preset parameter PRAD is an operating parameter applicable to the image capture units 110_1 and 110_2. In this embodiment, when at least one of the operating parameters PRA1 and PRA2 is judged to be an error, the image processor 130 uses one of the display data D1 and D2 to control the display 240. Therefore, the display 240 can display the screen corresponding to the image captured by the image capture units 110_1 and 110_2, and will not display an abnormal display result such as a black screen.

In this embodiment, the display 240 may be a display unit known to those skilled in the art. The display 240 may be, for example, a liquid crystal display (LCD), a light-emitting diode (LED), an organic light-emitting diode (OLED), or a display device that provides a display function. Also, a screen that uses a cold cathode fluorescent lamp (CCFL) or a light-emitting diode (LED) as a backlight module.

In this embodiment, the electronic device 200 further includes a driving circuit 250. The driving circuit 250 is coupled to the image processor 130. When the image capture units 110_1 and 110_2 are driven, the driving circuit 250 provides a driving signal SD to the image processor 130.

In this embodiment, the electronic device 200 further includes a Basic Input/Output System (BIOS) 260. The drive circuit 250 may provide a drive signal SD in response to the control of the BIOS 260, but the present disclosure is not limited thereto. In some embodiments, the drive circuit 250 may provide a drive signal SD in response to the control of other control circuits.

Please refer to Figures 3 and 4 at the same time. Figure 4 is a flow chart of an operating method according to an embodiment of the present disclosure. The operating method S200 is applicable to the electronic device 200. In this embodiment, the operating method S200 includes steps S210~S270. In step S210, the default parameter PRAD and the operating parameters PRA1 and PRA2 corresponding to the image capture units 110_1 and 110_2 are stored in the memory 120. In step S220, the image processor 130 responds to the drive signal SD to read the first operating parameter corresponding to the first image capture unit. For example, the drive signal SD is a signal used to instruct the electronic device 200 to drive the image capture unit 110_1. The first image capture unit is the image capture unit 110_1. The first operating parameter is the operating parameter PRA1. Therefore, the image processor 130 responds to the drive signal SD to read the operating parameter PRA1 stored in the memory 120. In step S230, the image processor 130 determines whether the operating parameter PRA1 is correct. The determination method of the operating parameter PRA1 has been clearly explained in the implementation example of step S130, so it will not be repeated here.

When the operating parameter PRA1 is determined to be correct, the image processor 130 uses the operating parameter PRA1 to control the image capture unit 110_1 in step S240 to receive the image data DIMG1 from the image capture unit 110_1, and uses the operating parameter PRA1 to convert the image data DIMG1 into display data DDP1. Next, the image processor 130 uses the display data DDP1 to control the display 240 in step S250.

On the other hand, when the operating parameter PRA1 is judged to be an error, the image processor 130 receives the second image data (i.e., one of the image data DIMGD1, DIMGD2) from one of the image capture units 110_1, 110_2 using the preset parameter PRAD in step S260, and converts the second image data into second display data (i.e., one of the display data D1, D2) using the preset parameter PRAD. Next, the image processor 130 controls the display 240 using the second display data in step S270.

In summary, the image processor responds to the driving signal to read the first operating parameter corresponding to the first image capture unit. When the first operating parameter is erroneous, the image processor uses the preset parameter to receive the second image data from one of the at least one image capture unit, and uses the preset parameter to convert the second image data into the second display data. In this way, when the operating parameter is erroneous, the electronic device can still receive the display data.

Although the present disclosure has been disclosed as above by way of embodiments, it is not intended to limit the present disclosure. Any person having ordinary knowledge in the relevant technical field may make some changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the definition of the attached patent application scope.
