Abstract
Disclosed is an electronic device which includes a processing block, a crosstalk compensation block, and a dark level compensation block. The processing block receives image data from an active pixel region of an image sensor and performs pre-processing on the image data. The crosstalk compensation block performs crosstalk compensation on the pre-processed image data. The dark level compensation block performs the crosstalk compensation on dark level data received from an optical black region of the image sensor and performs a subtraction operation on the crosstalk-compensated image data and the crosstalk-compensated dark level data.
