Patent ID: 8269839

Claim:
A high-resolution image sensing device, comprising: a two-dimensional sensing unit, for consecutively sensing a plurality of sensing frames, each including an image and an image position information of the image; a recording unit, for recording the sensing frames, and comprising: a base buffer, for buffering a base frame of the sensing frames; and a sampling buffer, for buffering a sampling frame of the sensing frames; a processing unit, comprising: a frame selecting unit, for selecting one of the sensing frames after the base frame as the sampling frame; an image comparing unit, for comparing image positions of the base frame and the sampling frame according to the image position information to generate a displacement information of the image; and a range selecting unit, for selecting at least a portion of the sampling frame according to the displacement information as a comparison range; wherein, the frame selecting unit selects a next sensing frame after the sampling frame and updates the next sensing frame as the sampling frame temporarily stored in the sampling buffer with respect to a comparison result of the image comparing unit, and the range selecting unit selects a comparison range of the base frame according to the image position information of the base frame, and the image comparing unit compares the image positions of the images in the comparison range of the base frame and the comparison range of the sampling frame respectively.
