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 image signal processor is provided. The image signal processor includes a white balancing block which performs white balancing on a raw RGB image of a Bayer pattern received from an image sensor on a kernel basis or in a kernel unit, a green generation block which performs cross-binning on white-balanced G pixel to generate a first green pixel, and adds a high-frequency component to which a preset weight is applied to generate a binned green pixel, a red-blue generation block which generates a U pixel and a V pixel indicating directionality, on the basis of the binned green pixel, a white-balanced R pixel, and a white-balanced B pixel, and merges the binned green pixel to each of the U pixel and the V pixel to generate a binned red pixel and a binned blue pixel and an inverse white balancing block which performs an inverse white balancing on the binned red pixel, the binned green pixel, and the binned blue pixel to output a final binning image.

Abstract: An image sensor having improved image quality is provided. The image sensor includes a first array of pixels, a second array of pixels, and a binning module. The first array of pixels has a color pattern formed in an n×m array and includes at least first-color pixels, second-color pixels, and third color-pixels. The second array of pixels is adjacent to the first array of pixels and has the same color pattern formed in an n×m array as the first array of pixels, to include at least first-color pixels, second-color pixels, and third color-pixels. The binning module is configured to, for a sensed image: perform binning on the first-color pixels of the first array, the first-color pixels of the second array, the second-color pixels of the first array, and the third-color pixels of the second array, and not perform binning on the third-color pixels of the first array, and not perform binning on the second-color pixels of the second array.

Abstract: An image processing method for converting a color space of input image data including color information is provided. The image processing method includes: preprocessing the input image data according to a frequency thereof to generate a preprocessed result; and color-converting the preprocessed result to generate output image data. The color space of the input image data is different from a color space of the output image data.

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.
