Abstract

A polarizing color imaging device comprising: a polarizing color filter having a first region for transmitting light in a first wavelength range polarized in a first direction, and a second region for transmitting light in a second wavelength range polarized in a second direction The second area through which the incident light is transmitted, and the third area through which at least a part of the incident light is transmitted; an imaging element, which arranges a plurality of unit blocks on the imaging surface, and each of the plurality of unit blocks has first to third a photosensitive element, and first to third polarizing filters arranged opposite to the first to third photosensitive elements respectively, and the polarized light transmission axis directions of the first to third polarizing filters are completely different; An optical lens for forming an image on the imaging surface of the imaging element.

Description

technical field [0001] The present application relates to a single-plate color imaging technology for obtaining a color image by using a set of optical systems and a so-called polarization imaging element in which a polarization filter is arranged to face each pixel. Background technique [0002] In recent years, digital cameras and digital video cameras using solid-state imaging devices such as CCDs and CMOSs ​​(hereinafter referred to as "imaging devices") have achieved remarkable improvements in functionality and performance. In particular, the miniaturization of the pixel structure in an imaging element is progressing along with the advancement of semiconductor manufacturing technology. As a result, high integration of pixels and drive circuits of the imaging element can be realized. As a result, the number of pixels in an imaging element has increased significantly from around 1 million pixels to more than 10 million pixels in just a few years. Recently, new functions...
