Image processing device and image processing method

An image processing method, comprising:

• acquiring first pixel data from a first pixel group corresponding to a first color, and acquiring second pixel data and third pixel data from a second pixel group and a third pixel group, respectively, which are arranged on both sides of the first pixel group and correspond to a second color distinguished from the first color;
• determining any one of the second pixel data and the third pixel data as interpolation reference data using different schemes depending on a type of edge that is detected based on a difference in the first color and a difference in the second color in an image region corresponding to the first pixel data;
• and
• interpolating a part of the first pixel data to correspond to the second color based on the determined interpolation reference data.

An electronic device, comprising:

• an image sensor including a first pixel group corresponding to a first color and a second pixel group and a third pixel group, which are arranged on both sides of the first pixel group and correspond to a second color distinguished from the first color;
• an acquirer configured to acquire image data including first pixel data acquired from the first pixel group, second pixel data acquired from the second pixel group, and third pixel data acquired from the third pixel group;
• a determiner configured to determine any one of the second pixel data and the third pixel data as interpolation reference data using different schemes depending on a type of edge that is detected based on a difference in the first color and a difference in the second color in an image region corresponding to the first pixel data based on the image data;
• and
• an interpolator configured to interpolate a part of the first pixel data to correspond to the second color based on the determined interpolation reference data.
