Embodiment 1

FIG. 1 is a schematic flowchart diagram of an embodiment of an anti-shake photographing method according to an embodiment of the present application. The anti-shake photographing method of the embodiment of the present application can be applied to various mobile terminals (such as mobile phones, tablet computers, etc.) having a photographing function. As shown in FIG. 1 , the defense of the embodiment of the present application The method of shaking the photographing may specifically include:

S101. When receiving the photographing instruction, pre-shooting a first photo under a normal exposure parameter and a second photo under a special exposure parameter.

Specifically, when the camera application is turned on, the photographing starts, the user presses the shutter, and the photographing instruction is issued after the auto exposure/autofocus is locked. The normal exposure parameter is the exposure parameter adjusted in the auto exposure mode. The quick exposure parameter is the corresponding exposure parameter when the exposure time and the exposure value are reduced based on the normal exposure parameter, which can be set manually.

S102. Extract luminance information and chrominance information from the first photo.

Specifically, since the first photo is taken under the exposure parameter adjusted in the automatic exposure mode, the luminance information and the chrominance information are more accurate, and thus the luminance information and the chrominance information are extracted from the first photo.

S103. Extract detailed information from the second photo.

Specifically, due to the same jitter condition, the shorter the exposure time, the better the anti-shake effect and the better the resolution, so clear detail information is extracted from the second photo.

S104: Perform image synthesis processing on the brightness information, the chrominance information, and the detail information, and output the obtained result photo.

Specifically, the image information synthesis processing is performed on the favorable information extracted from the first photo and the second photo, that is, the luminance information and the chrominance information extracted from the first photo and the detailed information extracted from the second photo. The resulting photo is output as the final result photo, and the user can save or delete the output photo as needed.

The anti-shake photographing method of the embodiment of the present application pre-shoots a first photo under a normal exposure parameter and a second photo under a special exposure parameter with a shorter exposure time and a lower exposure value, from the first photo The extracted luminance information and chrominance information and the detailed information extracted from the second photo are subjected to image synthesis processing, and the obtained result photo is output, and the anti-shake photographing function is implemented based on the software, and the camera mode in the digital camera is reduced. The volume of the group reduces the cost and power consumption during use.

When the subsequent pre-shooting operation and anti-shake processing are performed. When the exposure time is too short, for example, when the exposure time is less than 1/100 second, the jitter situation can be neglected, so no anti-shake processing is required, and normal shooting can be performed, thereby avoiding unnecessary shooting time.
