Abstract: An image processing device is provided. The imaging device includes: an image sensor configured to generate an original image; and a processor including: a remosaic processing circuit configured to generate a first remosaic image by performing remosaic processing on a first region of the original image by using a first remosaic method, and generate a second remosaic image by performing remosaic processing on a second region of the original image by using the first remosaic method or a second remosaic method; and a merging circuit configured to generate a converted image having a Bayer pattern based on the first remosaic image and the second remosaic image.

Abstract: An artificial neural network is provided, which is configured to convert a mosaic image representable by pixels with color pixel values corresponding to a plurality of colors to a plurality of color difference images corresponding to the plurality of colors. A plurality of output color difference images corresponding to the plurality of colors are generated based on an input mosaic image representable by pixels with color pixel values corresponding to the plurality of colors using the artificial neural network. A plurality of demosaiced color images corresponding to the plurality of colors are generated by summing, pixel by pixel, the input mosaic image and each of the plurality of output color difference images.

Abstract: A pixel array is provided. The pixel array includes: a plurality of color filter array (CFA) cells. Each of the plurality of CFA cells includes a plurality of CFA blocks provided along a width direction and a length direction. Each of the plurality of CFA blocks includes a first sub block and a second sub block. The first sub block includes m*n pixels having an interpolation distance of 0 during conversion into a Bayer pattern. The second sub block includes at least one pixel having the interpolation distance of 0 during conversion into the Bayer pattern among pixels outside the first sub block, where “m” and “n” are integers of at least 2. The m*n pixels of the first sub block include pixels corresponding to a first color, a second color and a third color. Respective second sub blocks of the plurality of CFA blocks form an inter-sub block in each of the plurality of CFA cells.
