Abstract

The invention provides an exposure control method and device, electronic equipment and a computer-readable storage medium. The method comprises the following steps: determining target exposure of theto-be-acquired image of each frame through photometry; according to the target exposure of the to-be-acquired image of each frame and the preset light sensitivity of the to-be-acquired image of each frame, determining the exposure duration of the to-be-acquired image of each frame; if the exposure duration of the to-be-acquired image of one or more frame is less than the lower limit of duration, updating the exposure duration of the to-be-acquired image of one or more frame according to the lower limit of duration; finally, performing exposure control according to the exposure duration and light sensitivity of the to-be-acquired image of each frame. Therefore, the dynamic range and overall brightness of night scene shot images are improved, and noise in the images is inhibited; moreover, ghost and fuzziness caused by hand shake are inhibited, the quality of the night scene shot images is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of imaging technology, and in particular to an exposure control method, device and electronic equipment. Background technique [0002] With the development of smart terminal technology, the use of mobile terminal devices (such as smart phones, tablet computers, etc.) is becoming more and more popular. Most mobile terminal devices have built-in cameras, and with the enhancement of mobile terminal processing capabilities and the development of camera technology, the performance of built-in cameras is becoming more and more powerful, and the quality of captured images is also getting higher and higher. Nowadays, mobile terminal devices are easy to operate and easy to carry, and more and more users use mobile terminal devices such as smart phones and tablet computers to take pictures in daily life. [0003] While smart mobile terminals bring convenience to people's daily photography, people's requirements for t...
