Image sensor having depth detection pixels and method for generating depth data with the image sensor

A method for generating depth data in an image sensor provided with a plurality of pixels including a plurality of color detection pixels, a plurality of depth detection pixels, and a plurality of phase difference detection pixels that are arranged in two dimensions, comprising:

• calculating a blur weight value from the plurality of phase difference detection pixels;
• extracting a first edge value from the plurality of color detection pixels;
• extracting a second edge value from the plurality of depth detection pixels;
• calculating a first blur value and a second blur value based on the first edge value and the second edge value using a Point Spread Function;
• amplifying the first blur value and the second blur value by reflecting the blur weight value into the first blur value and the second blur value;
• and
• generating depth information based on a difference between the amplified first blur value and the amplified second blur value.
