Problems solved by technology

[0003] In a darker environment, since the camera module is limited by its light-sensing ability, if the object in each video frame is fully exposed, a longer exposure time is required, resulting in the number of frames of the video shot per unit time The rate (the number of frames captured per unit time) is very low
At this time, the user will feel that the picture is not continuous
In addition, in this case, if the camera module uses a higher frame rate, the objects in each video frame will be underexposed, resulting in a very dark picture of the video frame
[0004] In addition, even in the case of sufficient light, usually the video generated by the camera module is not coherent due to the limited hardware processing capability (eg, 20FPS) of the camera module

Abstract

Disclosed are a video optimization method and information processing equipment using the video optimization method. The method comprises that a first video frame is acquired from a camera module according to a scheduled period; a second video frame is generated based on the current first video frame and a next first video frame, the current first video frame and the second video frame are respectively processed in an optimization mode in order to acquire a third video fame and a fourth video frame; the third video frame is inserted between the current first video frame and the second video frame; and the fourth video frame is inserted between the second video frame and the next first video frame, wherein a previous image region resulted from motion of moving objects in the third video frame is filled by black data, and a previous image region resulted from motion of moving objects in the fourth video frame is filled by black data.

Description

technical field [0001] The invention relates to a video optimization method and information processing equipment. Background technique [0002] Currently, due to the popularity of video chatting and video conferencing applications, it is becoming more and more common to use a camera module such as a notebook or a mobile phone to conduct video conversations. [0003] In a darker environment, since the camera module is limited by its light-sensing ability, if the object in each video frame is fully exposed, a longer exposure time is required, resulting in the number of frames of the video shot per unit time The rate (number of frames captured per unit time) is very low. At this time, the user will feel that the picture is not coherent. In addition, in this case, if the camera module adopts a higher frame rate, the objects in each video frame will be underexposed, resulting in a very dark picture of the video frame. [0004] In addition, even in the case of sufficient light,...
