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.

Image device and operation method of image device

An image apparatus may be configured to calculate a depth of an object relative to the image apparatus. The image apparatus may include an image sensor that may capture a plurality of images of the object. Depth calculation may include calculating a binocular disparity using the plurality of images, measuring a local temperature value from at least one temperature sensor, correcting a focal length of at least a portion of the image apparatus according to the measured local temperature value, and calculating a depth of the object using the binocular disparity and the corrected focal length. The corrected focal length may be determined based on a focal length variation value. The focal length variation value may be determined based on performing contrast autofocus on one or more captured images and the local temperature value.
