Abstract: An electronic device includes an image signal processor and a memory. The image signal processor receives a signal of a first code value that corresponds to an active pixel included in an active area, calculates a correction value based on a second code value associated with a first area and a third code value associated with a second area, and calculates an output code value based on the first code value and the correction value. The first area and the second area are different from the active area. The correction value includes a component of the third code value in proportion to a distance between the active pixel and the first area and includes a component of the second code value in proportion to a distance between the active pixel and the second area.
