Title:
IMAGING SYSTEM AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/147804
Kind Code:
A1
Abstract:
Provided are an imaging system and an image processing method. The imaging system comprises: an image sensor, a statistical unit and an exposure control unit. The statistical unit respectively compiles statistics on image data of each type of channel; and the exposure control unit calculates, according to statistical data of a type of channel, an exposure parameter corresponding to the type of channel, and controls, on the basis of the calculated exposure parameter, the brightness adjustment of image data of the type of channel. In view of the actual situation where the energy of light components to which different types of channels respond is different, image data of a type of channel is independently exposed, so that the brightness of the image data of the type of channel is controlled within an appropriate brightness range, thereby improving the final imaging effect.
