Image processing device, image processing method, program, and imaging device

An image processing device comprising:

• color reproduction processing circuitry configured to perform color reproduction processing on an image signal;
• and
• area detection circuitry configured to detect an image area having undergone a characteristic change exceeding a predetermined change amount, by using an image signal before the color reproduction processing and an image signal after the color reproduction processing,
• wherein the area detection circuitry is configured to determine, as a pixel of the image area having undergone a characteristic change exceeding a predetermined change amount, a pixel in which a pixel signal before the color reproduction processing is unsaturated and the pixel signal after the color reproduction processing is saturated.
