detailed description

The above described objects, features and advantages of the present invention will become more apparent from the detailed description of the appended claims. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a full understanding of the invention, but the invention may be practiced otherwise than as described herein. Limitations of the embodiments.

FIG. 1 shows a flow chart of a photographing method according to an embodiment of the present invention.

As shown in FIG. 1, a photographing method according to an embodiment of the present invention includes:

In step 102, when shooting is performed, the sensitivity required for the current shooting is determined.

Sensitivity is an ISO (International Standardization Organization) that quantifies the brightness.

Step 104: If the sensitivity required for the current shooting is greater than a set threshold, turn on the night shooting function of the dual camera.

Step 106: After the night scene shooting function is turned on, one of the dual cameras is used to capture a black and white image, another camera captures a color image, and the black and white image and the color image are combined to obtain a final display. image.

In the technical solution, if the sensitivity required for the current shooting is greater than the set threshold, indicating that the current environment is dark, the night scene shooting function is automatically turned on, thereby preventing the user from determining whether to enable the night scene shooting function, thereby making the terminal more intelligent. . In addition, after the night scene shooting function is turned on, the black and white image and the color image respectively captured by the dual camera are combined to obtain the final displayed image, thereby ensuring that the image finally displayed to the user is relatively clear after the night scene shooting function is turned on, thereby enhancing the user. The experience of using.

While one of the cameras in the dual camera captures the black and white image, the other camera captures the color image, and the outline based on the black and white image and the color image are colored, and the final displayed image is synthesized by an algorithm. The final displayed image benefits from the better detail of the black and white image. The final displayed image synthesized with the same lens as the sensor is much better than the single camera. When the dual camera is photographed, the focus position may be out of sync. If the black and white image is not as focused as the color image, the final displayed image is a color image. Or because one of the sharpness is caused by the jitter, the image is synthesized mainly with a clear image, thereby maximizing the success rate of the photograph.

Specifically, the photographing effect, time, and satisfaction are weighted to obtain a final value, and the set threshold is updated according to the value.

User satisfaction can be determined based on the user's behavioral actions. For example, after displaying the final synthesized image, if the user chooses to save the image, the user is satisfied with the image, and the satisfaction is 90%. If the user chooses to delete the image, the user is dissatisfied with the image, and is satisfied. The degree is 30%.

In addition, the set threshold may also be a fixed value, and the set threshold is determined according to the hardware configuration. For example, in the early days, because the shooting success rate was low, the threshold was set to 1600, that is, the sensitivity required for the current shooting reached 1600 or 1600 or more to activate the dual-camera night shooting function to improve the user experience. Or, in the medium term, the photo success rate has been significantly improved due to the improvement of the synthetic algorithm, and the photographing effect is balanced by the angle of the synthetic speed and the noise effect, and the threshold is set to 1400, that is, the sensitivity required for the current shooting reaches 1400 or 1400 or more to activate the double. Night view shooting function of the camera. Or when the hardware processing performance is improved, the synthesis time is reduced and the noise level is increased, and the threshold is set to 1000 or 800, that is, the sensitivity required for the current shooting reaches 1000 or more to activate the night shooting function of the dual camera.

In any one of the above aspects, preferably, the step of determining a sensitivity required for current shooting specifically includes: detecting a brightness of a current shooting environment; determining, according to a brightness of the current shooting environment, the current shooting requirement Sensitivity.

Among them, the lower the brightness of the current shooting environment, the greater the sensitivity required for the current shooting.

For example, if the user is shooting outdoors, since it is night and there is no light outside, the night scene shooting function is automatically turned on. If the user returns to the room for shooting, the indoor light intensity is relatively strong, and the shooting can be performed without turning on the night shooting function. For clearer photos, the night scene shooting function is automatically turned off to ensure that the captured images are sharper.
