Abstract: Image sensor having multiple pixels; a number of phase pixels which are included in the multiple pixels and which output a first signal indicating intensity of light; a first adjustment portion conducting gain adjustment on the number of phase pixels in reference to the first signal; an auto-focus portion adjusting a focal point of the image in reference to a second signal output from the number of phase pixels after the gain adjustment; a compensation portion generating and outputting a compensation signal indicating intensity of light received by the number of phase pixels in reference to signals output from the multiple pixels; a second adjustment portion determining exposure and gain for taking the image in reference to signals output from the multiple pixels and applying the exposure and the gain to the multiple pixels; and an image processing portion inputting both the compensation signal and signals and generating image data.
