Image processing device, system, and method for correcting focal plane distortion using a motion vector

摘要

According to one embodiment, an image processing device includes a motion vector generator, a correction amount generator, and a correcting module. The motion vector generator is configured to generate a horizontal direction motion vector and a vertical direction motion vector of an input video signal photographed in an order of scanning lines. The correction amount generator is configured to generate a horizontal direction correction amount based on the horizontal direction motion vector and the vertical direction motion vector by each scanning line, and generate a vertical direction correction amount based on the vertical direction motion vector by a scanning line. The correcting module is configured to correct the input video signal to generate an output video signal based on the horizontal direction correction amount and the vertical direction correction amount.
