AI Technical Summary
Technical Problem
Existing depth map generation techniques require multiple captures with different coded apertures, making it difficult to generate accurate depth maps when the imaging target moves.
Method used
A depth map generation system that uses a single imaging device with an encoded aperture, capturing multiple frames to create a composite frame by combining frames acquired at different times, thereby reducing the influence of object movement.
Benefits of technology
Enables the generation of accurate depth maps even when the imaging target moves, by averaging pixel values across frames to stabilize the position and range of blur.

Abstract
The present invention provides a depth map generation system, method, and program that can generate depth maps while mitigating the effects of movement of the imaging target. [Solution] A depth map generation system 100 that generates a depth map based on a plurality of captured images acquired using an imaging device 10 having an aperture portion 12 in which an encoded aperture 12a is formed by a liquid crystal panel, comprising: a synthesis unit that acquires a composite frame based on the first frame and the third frame of a plurality of captured images including a first frame, a second frame acquired after the acquisition of the first frame, and a third frame acquired after the acquisition of the second frame; and a depth map generation unit that generates a depth map based on the composite frame and the second frame.
