  • Patent number: 10345685
    Abstract: An image processing device includes a resolution reducer, a detector, and a corrector. The resolution reducer generates, from an input image, low resolution images for pixel shift display being lower in resolution than the input image. The detector detects portions of the low resolution images corresponding to a specific pattern in which image quality degradation may occur. The corrector performs specific correction processing to reduce the image quality degradation on the portions of the low resolution images corresponding to the specific pattern.
