An adaptive resolution transcoding system and method adaptively transcodes a source video with an optimized resolution and visual quality based on the video coding complexity (VCC) of the source video. The transcoding system is configured to receive a source video in its native format, and to obtain the video coding complexity score of the source video from a video coding complexity engine.

The invention provides a self-adaptive resolution ratio implementing method based on a CMOS image sensor. Firstly, whether a dynamic target exists in an image output by the CMOS image sensor is judged based on an image processing technology. When the dynamic target exists in a view field, the resolution ratio of the CMOS image sensor is adjusted to be the best according to image reorganization requirements; when no dynamic target exists in the view field, the resolution ratio of the CMOS image sensor is automatically reduced. According to the self-adaptive resolution ratio implementing method, through self-adaptively controlling the resolution ratio of the CMOS image sensor, redundant image information is reduced as much as possible, and use efficiency of the memory space of a hard disk is improved. Meanwhile, on the premise of meeting target reorganization, the resolution ratio of the image output by the sensor is self-adaptively reduced, and thereby a speed for recognizing the target is improved.
