Publication number: 20240386592Abstract: A depth calculating unit calculates a depth for each of a plurality of unit regions (for example, pixels) forming a depth map. A dividing unit divides an image region corresponding to a captured image into a plurality of partial regions. A noise removing unit removes, using a first parameter, noise from estimated depths calculated for a plurality of unit regions included in a first partial region. The noise removing unit removes, using a second parameter, noise from estimated depths calculated for a plurality of unit regions included in a second partial region. This prevents a problem in that an estimated depth that should originally be displayed is excluded from the depth map.Type: ApplicationFiled: May 13, 2024Publication date: November 21, 2024Inventors: Hitoshi TANAKA, Yoshiro AOKI, Hirondo NAKATOGAWA

Publication number: 20240386587Abstract: A pixel selection unit calculates deviation values indicating degrees of deviation of a real depth from a reference depth with respect to respective pixels based on a reference depth restored image reproduced from captured images using a PSF and the captured images. The pixel selection unit selects a depth indicating pixel based on changes of the deviation values of the pixels arranged in a pixel scanning direction. Thereby, accuracy of a depth displayed in a depth map may be increased.Type: ApplicationFiled: May 13, 2024Publication date: November 21, 2024Inventors: Hitoshi TANAKA, Hirondo NAKATOGAWA, Yoshiro AOKI
