Imaging device and signal processing circuit for the imaging device

Abstract

Switching is performed between generation of a luminance signal based on a visible light pixel signal and generation of a luminance signal based on a near infrared pixel signal in accordance with a comparison result between the visible light pixel signal level and the near infrared pixel signal level.

Description

technical field [0001] The present invention relates to an image pickup device including a plurality of pixels having sensitivity in the wavelength region of visible light and near-infrared light, an image pickup device that generates luminance signals and color signals from visible light pixel signals and near-infrared light pixel signals, and an image pickup device for such an image pickup device signal processing circuit. Background technique [0002] The entire contents of Japanese Patent Application No. 2008-260435 filed on October 7, 2008 including specification, drawings, and claims are hereby incorporated by reference into this specification. [0003] In a solid-state imaging element such as a CCD (Charge Coupled Device, a charge-coupled device) image sensor, a color filter for obtaining a color image (for example, a primary color filter that transmits light of three primary colors of red, green, and blue) ). Light of a specific wavelength band in visible light (wa...

AI Technical Summary

Problems solved by technology

In dark conditions such as at night, the amount of visible light is very small, so the sensitivity of the imaging element is insufficient, and good color images cannot be obtained

Especially in the use of vehicle-mounted cameras or surveillance cameras, the user's visual recognition is low, and it is desired to solve this problem
