Depth map generation system, depth map generation method, and information storage medium

A depth map generation method for generating a depth map based on a plurality of captured images acquired by using an imaging device including a diaphragm unit in which a coded aperture is formed by a liquid crystal panel, the plurality of captured images including at least a first frame, a second frame acquired after acquisition of the first frame, and a third frame acquired after acquisition of the second frame, the depth map generation method comprising:

• acquiring a combined frame based on the first frame and the third frame;
• and
• generating a depth map based on the combined frame and the second frame.

A non-transitory information storage medium storing a program for generating a depth map based on a plurality of captured images acquired by using an imaging device including a diaphragm unit in which a coded aperture is formed by a liquid crystal panel, the plurality of captured images including at least a first frame, a second frame acquired after acquisition of the first frame, and a third frame acquired after acquisition of the second frame, the program causing a computer to function as:

• a combination unit configured to acquire a combined frame based on the first frame and the third frame;
• and
• a depth map generation unit configured to generate a depth map based on the combined frame and the second frame.
