An image processing apparatus causes a composite image to be printed, on a recording sheet, as an entry area to be written in by a user. The composite image is formed by superimposing a fixed image on a reference image. The image processing apparatus extracts an image of an area having luminance lower than a predetermined threshold value from an image corresponding to the entry area contained in an image obtained by reading the recording sheet having the entry area that is written in, and the image processing apparatus uses mask data for extracting an image of an area corresponding to the fixed image to perform image extraction.
