Image processing device, image processing method, and computer program

An image processing device that performs a correction processing to correct a second frame based on a first frame and the second frame, comprising:

• a flicker component estimation unit comprising a processor, a circuit, or a combination thereof;
• and
• a pixel value correction unit comprising a processor, a circuit, or a combination thereof, wherein
• the flicker component estimation unit is configured to obtain a flicker component value based on pixel values of in-region pixels in the first and second frames,
• the in-region pixels are composed of a plurality of pixels that are located at same position and are included in a predetermined region in the first and second frames,
• the plurality of pixels include an attention pixel where a pixel value is to be corrected, and a surrounding pixel arranged around the attention pixel,
• the flicker component value corresponds to a degree of flicker occurring in an image display unit due to a pixel response delay in the in-region pixels when the first frame transits to the second frame,
• the pixel response delay corresponds to a response speed of an increasing pixel where a pixel value increases, being slower than or faster than a response speed of a decreasing pixel where a pixel value decreases among the plurality of pixels when the first frame transits to the second frame,
• the flicker occurs between the first frame and the second frame depending on how pixel values of an area of two or more pixels increase or decrease,
• the pixel value correction unit is configured to obtain a corrected pixel value based on the flicker component value, and
• the corrected pixel value is a value obtained by correcting the pixel value of the attention pixel in the second frame.
