Abstract
An imaging sensor is provided. The imaging sensor includes: a filter array used for extracting a specified color component of an incident light; and photoelectric elements for receiving the incident light via the filter array. The filter array includes: a green filter for extracting a green component; a red filter for extracting a red component; a blue filter for extracting a blue component; and a first infrared filter for extracting a first infrared component for the green component. The first infrared filter is implemented by the green filter and an infrared high-pass filter of a specific wavelength.
