摄像传感器以及摄像装置
Abstract:
本发明提供摄像传感器和摄像装置，在代替红外截止滤波器而使用DBPF的情况下，能够提高可见光拍摄时的颜色再现性。摄像传感器(1)具有彩色滤光片(3)和DBPF(5)，该DBPF(5)在可见光波段具有透过特性，在与该可见光波段的长波长侧相邻的第1波段具有遮断特性，在作为第1波段内的一部分的第2波段具有透过特性。设定DBPF的透过特性和彩色滤光片(3)的各滤光部的透过特性，以便使DBPF(5)的第2波段包含于在相对于可见光波段的长波长侧各颜色的滤光部的透过率相互近似的波段即第3波段，并且包含于红外光用的上述滤光部具有透过特性的波段即第4波段中。
Abstract(English):

An imaging sensor includes a color filter, and DBPF that has a transmission characteristic in a visible-light band, a blocking characteristic in a first wavelength band adjacent to a long-wavelength side of the visible-light band, and a transmission characteristic in a second wavelength band that is a part of the first wavelength band. A transmission characteristic of DBPF and a transmission characteristic of each filter part of the color filter are set in such a manner that the second wavelength band of DBPF is included in a third wavelength band that is a wavelength band in which transmittance of the filter parts in colors is approximate to each other on a long-wavelength side of the visible-light band and a fourth wavelength band that is a wavelength band in which a filter part for infrared light has a transmission characteristic.
