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.

Abstract: 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.
