An image processing apparatus includes: a signal receiver configured to receive an input image; an image processor configured to process the input image and generate an output image; a storage configured to store a first patch corresponding to a first pixel of the input image; and a controller configured to control the image processor to generate the output image by applying the first patch stored in the storage to the first pixel.

Image processing apparatus and recording medium

Disclosed is a local dimming liquid crystal display device. The present local dimming liquid crystal display device comprises a display panel unit having a plurality of pixels; a panel driving unit for driving each of the plurality of pixels; a backlight unit comprising a plurality of backlights for dividing the display panel unit into a plurality of areas to emit light to each of the plurality of regions; a backlight driving unit for driving the plurality of backlights on the basis of gray level information of the plurality of pixels corresponding to each of the plurality of areas; and a processor for calculating a first amount of light to be incident on each pixel on the basis of the gray level of each pixel, calculating a second amount of light incident on each pixel in accordance with a driving state of the plurality of back-lights, changing the gray level of at least one of the plurality of pixels on the basis of the difference between the first amount of light and the second amount of light, and controlling the panel driving unit on the basis of the changed gray level.

Liquid crystal display device and driving method thereof

A display apparatus is provided. The display apparatus according to an exemplary embodiment includes a display, and a processor configured to generate a second image and a third image where a dynamic range is expanded by respectively applying a first gain and a second gain to an input first image, generate a degraded image of the second image by applying a predetermined degradation model to the second image, based on a difference value between a pixel of the degraded second image and a pixel of the third image satisfying a predetermined condition, modify a pixel value of the second image based on the difference value, and output the second image where the pixel value is modified through the display.

Display device and display method therefor

A method of reconstructing a high-resolution image by using multi-layer low-resolution images includes dividing a low-resolution image into a plurality of texture layer low-resolution images and a plurality of base layer low-resolution images; generating a texture layer high-resolution image by compositing the plurality of the texture layer low-resolution images and generating a base layer high-resolution image by compositing the plurality of the base layer low-resolution images; and outputting a high-resolution image by compositing the texture layer high-resolution image and the base layer high-resolution image.
