Abstract: An image processing system includes a movable lens that transfers an external light, an image sensor that includes a pixel array that generates an image signal based on the light and generates image data based on the image signal, and a processor that generates focus information for controlling a position of the movable lens and that generates a depth map based on calibration data and the image data. The calibration data include a value that depends on a position of the objective lens and a position of a pixel included in the pixel array.

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: An imaging system for generating a high dynamic range (HDR) image includes a pixel array that includes first pixels and second pixels, a driver circuit configured to control the first pixels based on a first exposure time and control the second pixels based on a second exposure time, an output circuit configured to output first pixel values of the first pixels and second pixel values of the second pixels from the pixel array, and a processing device configured to generate the HDR image based on a first Bayer image and a second Bayer image, where the first Bayer image is generated based on the first pixel values and the second Bayer image is generated based on the second pixel values and third pixel values of the first Bayer image. The quantity of pixels of the first pixels may be greater than the quantity of pixels of the second pixels.
