IMAGE CAPTURE DEVICE, ANOMALOUS OBLIQUE INCIDENT LIGHT DETECTION METHOD, AND RECORDING MEDIUM

摘要

In an aspect of the invention, plural pixels constituting a color image pickup device include a first pair of RB pixels and a second pair of RB pixels both constituted by a red pixel R having a red color filter and a blue pixel B having a blue color filter in a horizontal direction A and vertical direction B, the red pixel and the blue pixel being adjacent to each other. A position of the red pixel R and a position of the blue pixel B are opposite to each other between the first pair of RB pixels and the second pair of RB pixels. Pixel data of the blue pixel B of the first pair of RB pixels is compared with pixel data of the blue pixel of the second pair of RB pixels to detect whether or not anomalous oblique incident light is incident on the color image pickup device.

主权项

1. An image capture device comprising:
an image pickup device having plural pixels arranged in a first direction and a second direction perpendicular to the first direction, each of the plural pixels including a color filter and a photodiode receiving a light having passed through the color filter to output pixel data; and an anomalous oblique incident light detection device that detects whether or not an anomalous oblique incident light is incident on the image pickup device on the basis of the pixel data, wherein the plural pixels include a first pixel pair and a second pixel pair which are each constituted by a first-color pixel having a first-color color filter and a second-color pixel having a second-color color filter, the first-color pixel and the second-color pixel being adjacent to each other in at least one of the first direction and the second direction, and have an arrangement in which a position of the first-color pixel and a position of the second-color pixel are opposite to each other, the first-color color filter has a transmission rate higher than the second-color color filter in at least a part of a red light wavelength range, and the anomalous oblique incident light detection device compares the pixel data of the second-color pixel of the first pixel pair with the pixel data of the second-color pixel of the second pixel pair to detect whether or not the anomalous oblique incident light is incident.
