Video signal processing apparatus and method with infrared component remover

An image sensor for receiving light through a color filter, the color filter comprising long-pass filters only or a combination of a long-pass filter and an all-transmissive filter, the long-pass filters including a visible-light transmissive long-pass filter for permitting a visible-light component and an infrared-light component to pass therethrough and an infrared-light transmissive long-pass filter for permitting an infrared-light component to pass selectively therethrough;

• and
• wherein, when a signal has passed through the visible-light transmissive long-pass filter, an infrared-light component is configured to be removed therefrom, with transmittance data of an infrared-light region of the visible-light transmissive long-pass filter and the infrared-light transmissive long-pass filter applied.

A video signal processing method of a video signal processing apparatus, comprising steps of:

• receiving, on an image sensor, light through a color filter, the color filter including long-pass filters only or a combination of a long-pass filter and an all-transmissive filter, the long-pass filters in the color filter including a visible-light transmissive long-pass filter for permitting a visible-light component and an infrared-light component to pass therethrough and an infrared-light transmissive long-pass filter for permitting an infrared-light component to pass selectively therethrough;
• and
• removing an infrared-light component contained in a signal having passed through the visible-light transmissive long-pass filter, with transmittance data of an infrared-light region of the visible-light transmissive long-pass filter and the infrared-light transmissive long-pass filter applied.

A non-transitory computer-readable storage medium storing a computer program which, when executed by a video signal processing apparatus, causes the video signal processing apparatus to perform a video signal processing method, the method including:

• receiving, on an image sensor, light through a color filter, the color filter including long-pass filters only or a combination of a long-pass filter and an all-transmissive filter, the long-pass filters in the color filter including a visible-light transmissive long-pass filter for permitting a visible-light component and an infrared-light component to pass therethrough and an infrared-light transmissive long-pass filter for permitting an infrared-light component to pass selectively therethrough;
• and
• removing an infrared-light component contained in a signal having passed through the visible-light transmissive long-pass filter, with transmittance data of an infrared-light region of the visible-light transmissive long-pass filter and the infrared-light transmissive long-pass filter applied.
