METHOD AND DEVICE FOR PROCESSING IMAGE DATA
First Claim
1. A method of processing image data, the method comprising:
- determining first characteristic values respectively of a plurality of regions of a first image by sequentially calculating, for each of the plurality of regions, characteristic values corresponding to each of pixel values of pixels included in each of the plurality of regions while sequentially receiving the pixel values of the pixels;
obtaining, based on the determined first characteristic values, an illumination image related to a second image that is a following image of the first image; and
modifying, based on the obtained illumination image, the second image.
