The embodiment of the invention discloses a brightness adjusting method based on double camera modules and wearable equipment, which can improve the output effect of video images when the environment brightness of the environment where the wearable equipment is located is poor, and provide better video call experience for a receiving terminal user. The following detailed description is made with reference to the accompanying drawings.

First, a wearable device according to the present invention is briefly introduced, please refer to fig. 1, and fig. 1 is a schematic structural diagram of a wearable device based on dual camera modules according to an embodiment of the present invention. Wherein, this wearable equipment includes wearable equipment's intelligent host computer 101, pivot 102, bottom support 103 and watchband 104, and intelligent host computer 101 is including just to the host computer top side and the host computer bottom side that set up, and the host computer top side can be provided with leading module 1011 and the display screen 1012 of making a video recording, and the host computer bottom side can be provided with the rearmounted module 1013 of making a video recording.

This has not only solved current wearable equipment (only have one usually and shoot the module) and need the user to twist the problem of the adjustment shooting angle that the arm just can realize, still can satisfy the shooting demand of user's different angles simultaneously.

Example one

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a brightness adjustment method based on two camera modules according to an embodiment of the present invention. As shown in fig. 2, the method may include the following steps.

201. The intelligent host judges whether the environmental brightness value of the environment where the wearable device is located is larger than a preset brightness threshold value or not in the video call process. If not, go to step 202; otherwise, the flow is ended.

In the embodiment of the present invention, the wearable device may include a smart watch, a smart bracelet, and other portable devices, which are not limited in the embodiment of the present invention.

In the embodiment of the invention, the intelligent host can be provided with a starting button, the button is pressed as a video call instruction, and when the starting button is detected to be pressed, the intelligent host starts a video call function; or, a voice module may be built in the smart host, and the voice module is used to identify voice information input by the user, and when a video call instruction is identified, such as "please start a video call", the smart host starts a video call function.

As an optional implementation, before the wearable device performs step 201, the following steps may also be performed:

the intelligent host detects whether a start button representing a video call instruction is pressed;

if yes, the intelligent host calculates the target duration of the pressed starting button and judges whether the target duration is greater than the preset duration or not;

if the time length is longer than the preset time length, the intelligent host starts the video call function; if not, the flow is ended.

When the target duration is longer than the preset duration, the user can input a video call instruction by pressing the start button, and the intelligent host starts a video call function; when the target duration is not greater than the preset duration, the start button is considered to be touched by mistake, and the intelligent host does not start the video call function. The efficiency of starting the video call function can be improved on the premise that the video call instruction is not triggered by mistake.

In the embodiment of the invention, the intelligent host can be internally provided with the photosensitive circuit, the circuit can be provided with the photosensitive resistor, and the photosensitive resistor is very sensitive to the change of light, so that the resistance value of the photosensitive resistor can be obviously changed under the irradiation of the light, thereby causing the change of the voltage or the circuit in the photosensitive circuit. With the characteristics of the photoresistor, the intelligent host can detect the ambient brightness through the built-in photosensitive circuit of the intelligent host correspondingly, and therefore the ambient brightness value is obtained. Therefore, the intelligent host can detect the environment brightness in the video call process, so that the environment brightness value is obtained to judge whether the environment brightness value of the environment where the wearable device is located is larger than the preset brightness threshold value.

In the embodiment of the present invention, the intelligent host may store the preset brightness threshold, and when the intelligent host detects the environmental brightness value of the environment, the intelligent host may determine whether the environmental brightness value is greater than the preset brightness threshold, and if not, execute step 202; if so, the flow ends.

Further, the preset brightness threshold stored by the smart host may be fixed or may also be changed, and the embodiment of the present invention is not limited.

For example, the brightness value of the outdoor normal bright environment is 800lx, the brightness value of the night normal dark environment is 100lx, the preset brightness threshold value stored by the intelligent host can be 500lx, and when the brightness value of the environment detected by the intelligent host is 700lx, it indicates that the wearable device can perform normal video call in the current environment; when the environment brightness value detected by the smart host is 150lx, indicating that the environment where the wearable device is currently located is not favorable for video call, execute step 202.

202. The intelligent host adjusts the backlight brightness value of the display screen to be a target brightness value, and performs brightness parameter compensation on the rear camera module to adjust the shooting brightness value of the rear camera module to be the target brightness value, wherein the target brightness value is larger than or equal to a preset brightness threshold value.

In the embodiment of the present invention, the intelligent host may store a target brightness value, where the target brightness value is greater than or equal to the stored preset brightness threshold, and further, the target brightness value may be fixed or not fixed, which is not limited in the embodiment of the present invention.

As an optional implementation manner, the manner of adjusting the backlight brightness value of the display screen to the target brightness value by the smart host is as follows:

the intelligent host reads a target brightness value parameter stored by the intelligent host;

and the intelligent host adjusts the backlight brightness value parameter of the display screen so as to keep the backlight brightness value parameter of the display screen consistent with the target brightness value parameter, and thus the backlight brightness value of the display screen is adjusted to be the target brightness value.

As another optional implementation, the mode that the intelligent host performs brightness parameter compensation on the rear camera module to adjust the shooting brightness value of the rear camera module to the target brightness value is as follows:

taking the target brightness value parameter as a reference, calculating the ratio of the target brightness value parameter to the shooting brightness value parameter of the rear camera module by the intelligent host, and taking the ratio as a compensation value of the shooting brightness value of the rear camera module;

according to the compensation value, the intelligent host adjusts the shooting brightness value of the rear camera module, so that the shooting brightness value of the rear camera module is adjusted to be a target brightness value.

For example, the target brightness value stored by the intelligent host is 600lx, the backlight brightness value of the display screen is 400lx, and the shooting brightness value of the rear camera module is 400lx, at this time, the intelligent host can adjust the backlight brightness value of the display screen to 600lx, so that the backlight brightness value of the display screen is the same as the target brightness value; and the intelligent host can calculate the ratio of the target brightness value to the shooting brightness value parameter of the rear camera module by taking the target brightness value parameter as a reference, and uses the ratio as a compensation value of the shooting brightness value of the rear camera module, and according to the compensation value, the intelligent host adjusts the shooting brightness value of the rear camera module to 600lx, and the shooting brightness value of the rear camera module is the same as the target brightness value.

Implement above-mentioned two kinds of methods, the intelligent host computer can be after the environment brightness value of judging wearable equipment environment is not more than predetermineeing the luminance threshold value, all adjust the luminance value in a poor light of display screen and the shooting luminance value of rearmounted module of making a video recording to the video image that makes leading the module of making a video recording and the rearmounted module of making a video recording shoot is more clear, and furtherly, can also satisfy when using leading the module of making a video recording and rearmounted module of making a video recording simultaneously, the video image luminance that two modules of making a video recording shot can keep unanimous.

203. The intelligent host controls the front camera module to shoot a first video image which is displayed on the display screen and corresponds to the target brightness value, and/or controls the rear camera module to shoot a second video image which is obtained and corresponds to the target brightness value.

In the embodiment of the present invention, the first video image captured by the front camera module may be a video image of a user, and the second video image captured by the rear camera module may be a video image of a surrounding environment or a video image of a surrounding person, which is not limited in the embodiment of the present invention.

It can be seen that, when the environment brightness of the environment where the wearable device is located is poor, the method described in fig. 2 is implemented, the backlight brightness value of the display screen can be adjusted to be greater than or equal to the target brightness value of the preset brightness threshold value, so that the video image shot by the front camera module is relatively clear, and meanwhile, the shooting brightness value of the rear camera module is also adjusted to be the target brightness value, so that the video image shot by the rear camera module is relatively clear under the environment brightness, and it can be ensured that the wearable device can obtain a clear video image when the front camera module or the rear camera module is used, or the front camera module and the rear camera module are used for video call.

Example two

Referring to fig. 3, fig. 3 is a schematic flow chart illustrating another brightness adjustment method based on dual camera modules according to an embodiment of the present invention. As shown in fig. 3, the method may include the following steps.

301. The intelligent host judges whether the environmental brightness value of the environment where the wearable device is located is larger than a preset brightness threshold value or not in the video call process. If not, go to step 302; otherwise, the flow is ended.

302. The intelligent host adjusts the backlight brightness value of the display screen to be a target brightness value, and performs brightness parameter compensation on the rear camera module to adjust the shooting brightness value of the rear camera module to be the target brightness value, wherein the target brightness value is larger than or equal to a preset brightness threshold value.

303. The intelligent host controls the front camera module to shoot a first video image which is displayed on the display screen and corresponds to the target brightness value, and/or controls the rear camera module to shoot a second video image which is obtained and corresponds to the target brightness value.

304. The intelligent host divides a display page on a display screen to display a first video image and a second video image, wherein the display page comprises a first display page and a second display page, the first video image is displayed on the first display page, the second video image is displayed on the second display page, and the first display page and the second display page are switched through a sliding instruction of a user.

305. And the intelligent host receives a third video image sent by a receiving terminal connected with the wearable device.

In this embodiment of the present invention, the third video image sent by the receiving terminal may be a video image of a user (e.g., a parent) at the receiving end, or may be a video image of an environment around the receiving end.

306. And the intelligent host displays a third video image on a third display page, wherein the display page also comprises the third display page.

In the embodiment of the present invention, the sliding instruction of the user may be sliding up and down or sliding left and right, which is not limited in the embodiment of the present invention.

For example, in the video call process, the user sees that the display screen displays the first video image corresponding to the user, at this time, the user can slide the display page left and right (or slide up and down), and switch the display page to the second video image corresponding to the environment (or people around the wearable device), and then the user can continue to slide the display page left and right (or slide up and down), and switch the display page to the third video image corresponding to the parent (or the environment around the receiving end). The user can check the corresponding video image according to the decision, and the video call experience of the user is improved.

307. The intelligent host detects whether a screen capture instruction input by a user is received, wherein the screen capture instruction is used for indicating to capture the current screen content of the display screen. If so, go to step 308; otherwise, the flow is ended.

In the embodiment of the invention, the intelligent host can be provided with a screen capture button, the button is pressed down to be used as a screen capture instruction, and when the screen capture button is detected to be pressed down, the intelligent host captures the current screen content of the display screen; or, a voice module may be built in the smart host, and the voice module is used for recognizing voice information input by the user, and when a screen capture instruction is recognized, such as "please capture the screen", the smart host captures the current screen content of the display screen.

For example, during a video call, a user can see that himself (or the surrounding environment or parents) on the display screen is good and has commemorative significance, and at the moment, the user can input a screen capture instruction, and the intelligent host computer captures the current screen content of the display screen.

308. The intelligent host intercepts the current screen content of the display screen and sends the current screen content to a receiving terminal connected with the wearable device in a picture format.

As an optional implementation manner, the smart host may make the first video image (or the second video image, or the third video image) of the display screen within a certain time into a motion picture format (e.g., GIF format), and send the made motion picture format to the receiving terminal connected to the wearable device for the receiving terminal to store, so as to facilitate subsequent calls.

As another optional embodiment, after the wearable device performs step 308, the following steps may be further performed:

the intelligent host sends a viewing instruction to a receiving terminal connected with the wearable device, wherein the viewing instruction is used for indicating to view picture information;

the intelligent host receives picture information sent by a receiving terminal connected with the wearable device;

the intelligent host detects a confirmation instruction input by a user, wherein the confirmation instruction is used for indicating that a selected picture is confirmed;

and the intelligent host receives and downloads the pictures sent by the receiving terminal connected with the wearable device.

For example, a user wants to take a picture taken in 9 months and 29, after the user inputs a viewing instruction, the user can see picture information of all taken pictures on a display screen of the intelligent host, the picture information can include picture thumbnails, the taking time and the like, after the user selects a picture, a confirmation instruction is input, then the intelligent host receives and downloads the picture, and the user can correspondingly operate the picture.

By implementing the method, the user can check, download, edit and the like all the intercepted pictures, and the wearing experience of the user is improved.

It can be seen that, when the environment brightness of the environment where the wearable device is located is poor, the method described in fig. 3 is implemented, the backlight brightness value of the display screen can be adjusted to be greater than or equal to the target brightness value of the preset brightness threshold value, so that the video image shot by the front camera module is relatively clear, and meanwhile, the shooting brightness value of the rear camera module is also adjusted to be the target brightness value, so that the video image shot by the rear camera module is relatively clear under the environment brightness, and it can be ensured that the wearable device can obtain a clear video image when the front camera module, the rear camera module or both the front camera module and the rear camera module are used for video call. In addition, by implementing the method described in fig. 3, the user can switch the first display interface, the second display interface, and the third display interface through a sliding operation on the display screen, so as to determine to view the corresponding video image, thereby improving the video call experience of the user. In addition, when the method described in fig. 3 is implemented, the user can save the content of the current display screen through screen capture and send the content to the receiving terminal connected to the wearable device for subsequent user invocation.

EXAMPLE III

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another brightness adjustment method based on dual camera modules according to an embodiment of the present invention. As shown in fig. 4, the method may include the following steps.

401-408; wherein, steps 401 to 408 are the same as steps 301 to 308 in the second embodiment, and are not described herein again.

409. When a first video image is obtained through shooting, the intelligent host sends the first video image to a receiving terminal connected with the wearable device; when a second video image is obtained through shooting, the intelligent host sends the second video image to a receiving terminal connected with the wearable device; when the first video image and the second video image are obtained through shooting, the intelligent host synthesizes the first video image and the second video image to obtain a target video, and sends the target video to a receiving terminal connected with the wearable device.

It should be noted that, after the intelligent host controls the front camera module to shoot the first video image displayed on the display screen and corresponding to the target brightness value, and/or controls the rear camera module to shoot the second video image corresponding to the target brightness value, step 409 is executed.

The

steps

404 and 409 may be executed simultaneously, or the step 404 may be executed first and then the step 409 is executed, or the step 409 may be executed and then the step 404 is executed, which is not specifically limited in the embodiment of the present invention.

In this embodiment of the present invention, the target video may be synthesized by left-right stitching or top-bottom stitching, or a second video image may be embedded in a first video image or a first video image may be embedded in a second video image, which is not limited in this embodiment of the present invention.

It can be seen that, when the environment brightness of the environment where the wearable device is located is poor, the method described in fig. 4 is implemented, the backlight brightness value of the display screen can be adjusted to be greater than or equal to the target brightness value of the preset brightness threshold value, so that the video image shot by the front camera module is relatively clear, and meanwhile, the shooting brightness value of the rear camera module is also adjusted to be the target brightness value, so that the video image shot by the rear camera module is relatively clear under the environment brightness, and it can be ensured that the wearable device can obtain a clear video image when the front camera module or the rear camera module is used, or the front camera module and the rear camera module are used for video call.
