Abstract
An image processing device determines a first brightness value of a first pre-specified area in proximity to an object mask of an object in a source image and a first average color value of the source image, and determines a second brightness value of a second pre-specified area in proximity to an object mask of the object in a target image and a second average color value of the target image. The brightness value of each pixel of the object in the target image is adjusted based on a ratio of the second brightness value and the first brightness value. A color value of each pixel of an object in the target image is adjusted when a difference value between the first average color value and the second average color value exceeds a threshold color value.
