Abstract
A high dynamic range image sensing method for an image sensing device is provided. The high dynamic range image sensing method comprises: calculating a brightness sum value of a pixel block to obtain a long exposure value; calculating a brightness average value of the pixel block to obtain a short exposure value; calculating a block average value of a plurality of adjacent pixel blocks; obtaining a weight value according to the block average value; and outputting a high dynamic range pixel value of one pixel according to the long exposure value, the short exposure value and the weight value.
