摘要:
An image correction device includes a processor that executes a procedure. The procedure includes: correcting an image of a read object based on images stored in a storage section of a self-illuminated reference chart image of a reference chart of size corresponding to a mounting region where the read object is mounted that has been read in advance in a state illuminated by only a self-illumination light, a uniform light standard color chart image of a standard color chart that has been read in advance in a state illuminated by only uniform light from a predetermined uniform light source, and a uniform light reference chart image of the reference chart that has been read in advance in a state illuminated by only the uniform light, and based on the image of the read object and a peripheral light standard color chart image read by a reading section.
