Abstract: An electronic device includes an image sensor configured to capture a target to generate first image data, and a processor configured to perform directional interpolation on a first area of the first image data to generate first partial image data, perform upscale on a second area of the first image data to generate second partial image data, and combine the first partial image data and the second partial image data to generate second image data.

Abstract: A pixel array includes a plurality of pixel groups. Each of the plurality of pixel groups includes a plurality of subpixels arranged in an M×N matrix, where M is a natural number equal to or greater than 2, and N is a natural number equal to or greater than 2, as well as a plurality of color pixels configured to sense pieces of light having different wavelength bands. Each of the plurality of color pixels includes a same number of phase detection pixels.

Abstract: An operating method of an imaging device comprising a plurality of shared pixels that share a floating diffusion node and each comprising sub-pixels covered by a micro-lens. The method involves generating a capture image from the plurality of shared pixels that receive light reflected from an object; compensating for the capture image using static phase information based on misalignment of the micro lens of each of the plurality of shared pixels; performing auto exposure control based on the compensation of the capture image; performing auto focus control based on the compensated capture image; and generating an output image by processing the compensated capture image.

Abstract: In a method of color decomposition, inter-color images indicating similarity between color sensitivities are generated based on color images. Conversion coefficients of the color images and the inter-color images with respect to a white image are determined. A pseudo-white image corresponding to the color images and the inter-color images is generated using the conversion coefficients the pseudo-white image similar to a real white image is generated using the inter-color images indicating similarity between color sensitivities. Deep learning of the artificial neural network is performed efficiently using the color images and the pseudo-white image and the demosaiced images of high quality are generated using the trained artificial neural network that is trained.
