Abstract
The present invention discloses a region based shutter adaptation method for image exposure. The method includes the steps of: (a) providing an image which is non-uniformly illuminated; (b) segmenting the image into two or more non-overlapping regions; (c) identifying brightness values for each of the regions when more than one brightness value has been produced for each of the regions; (d) applying the whole image with different shutters for different regions; and (e) exposing different regions for different exposure durations according to the brightness values respectively assigned to the regions, so that the present invention is capable of enabling different regions within the whole image which is non-uniformly illuminated to have different shutter adaptions.

A region based shutter adaptation method for image exposure, comprising the steps of:
- (a) obtaining an image, wherein the image includes a plurality of pixel units and each pixel unit includes pixels of different colors, and wherein at least one region consists of pixels of only one color;
- (b) segmenting the image into two or more non-overlapping regions;
- (c) identifying a brightness value of each of the regions;
- and
- (d) applying exposure parameters to the regions according to the brightness values of the regions, respectively, wherein the exposure parameter applied to one of the regions is different from the exposure parameter applied to at least another one of the regions.
A region based shutter adaptation method for image exposure, comprising the steps of:
- (a) obtaining an image, wherein the image includes a plurality of pixels, and at least one region includes pixels which are not directly or indirectly neighboring to one another;
- (b) segmenting the image into two or more non-overlapping regions;
- (c) identifying a brightness value of each of the regions;
- and
- (d) applying exposure parameters to the regions according to the brightness values of the regions, respectively, wherein the exposure parameter applied to one of the regions is different from the exposure parameter applied to at least another one of the regions.
