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.

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 device includes a pre-processing module that generates a first image by performing a binning operation in a first mode and generates a second image by performing a remosaic operation in a second mode; a calibration module that generates calibration data based on a first image and a second image, the calibration data including a code level difference of the first image and the second image for each of a plurality of colors by a grid unit; and a compensation module that generates a calibration image by decoding the calibration data, and generates a compensated second image associated with a raw image by summing the second image associated with the raw image and the calibration image to compensate for a color tone difference between the first mode and the second mode by the grid unit.
