AI Technical Summary

Technical Problem

Imaging devices with a stereo lens configuration capture 3D images that cause discomfort due to differing interpupillary distances between frontal and peripheral images, especially in VR applications.

Method used

The imaging device employs a pixel array with beam selection units that adjust the light beams passing through specific pupil regions of the exit pupil region of the photographing lens, ensuring consistent interpupillary distance across the field of view by aligning the beam selection units of each pixel with predetermined pupil regions, including inner and outer pupil regions for central and peripheral pixels.

Benefits of technology

This configuration reduces the sense of discomfort when viewing stereoscopic video by maintaining a consistent interpupillary distance, enhancing the viewing experience in VR applications.

Abstract

The present disclosure relates to an imaging element and an imaging device that make it possible to reduce a sense of incongruity during stereoscopic video viewing. This imaging element comprises a pixel array in which a plurality of pixels is arranged in a matrix, and the pixel array comprises the pixel comprising a light flux selection part that selects a light flux passing through a predetermined pupil region within an exit pupil region of a first imaging lens. The light flux selection part of a first pixel that is a pixel at the center of the optical axis of the first imaging lens selects a light flux passing through a first pupil region as the predetermined pupil region, and the light flux selection part of a second pixel located at a predetermined distance away from the first pixel in the row direction of the pixel array selects a light flux passing through a second pupil region as the predetermined pupil region. The first pupil region is a region including a first end of the exit pupil region of the first imaging lens, and the second pupil region is a region including a second end of the exit pupil region of the first imaging lens. The technology of the present disclosure can be applied to, for example, an imaging element that generates a stereoscopic video.
