Abstract
An image processing device includes a memory and a color correction circuit. The memory stores first correction information that used for correcting first pixel values among a plurality of pixel values. The plurality of pixel values are received from an auto-focus image sensor including first pixels configured to detect a phase difference and second pixels configured to detect an image. The first pixel values are obtained from the first pixels and correspond to a first color. The first correction information is used for correcting the first pixel values to correspond to a second color different from the first color. The color correction circuit receives first image frame data including the plurality of pixel values from the auto-focus image sensor, loads the first correction information from the memory, and generates first corrected image frame data by correcting the first pixel values included in the first image frame data to correspond to the second color based on the first correction information.
