Patent ID: 8018509

Claim:
An image input processing apparatus comprising: an optical band separating filter that intercepts a predetermined wavelength band of near infrared light, and transmits bands on shorter and longer wavelength sides of the predetermined wavelength band; a color filter of a four-color arrangement having an equivalence in which a sum of two colors is equivalent to one other color in a visible light region or a sum of three colors is equivalent to once or twice one other color in the visible light region; an optical sensor section that receives light having undergone wavelength band separation and color selection by way of the optical band separating filter and the color filter, for each color with a pixel as a unit, and generates an imaging signal; a data separating section that separates pixel data, corresponding to the four-color arrangement, of the imaging signal into pieces of pixel data of four colors; an infrared separating section that separates a near infrared light component, in the longer wavelength side band, separated by the optical band separating filter, from the pixel data by a subtraction using the equivalence in the visible light region based on the four-color arrangement among the pieces of pixel data of the four colors after the separation; a first integrating section that integrates, for each color, a plurality of pieces of pixel data that are outputted from the data separating section and have not been inputted to the infrared separating section yet; a second integrating section that integrates, for each color, a plurality of pieces of pixel data outputted from the infrared separating section; and a camera control processing section that compares a first integration value of each color from the first integrating section with a second integration value of each color from the second integrating section, and performs a camera control processing suitable for each image depending on the amount of the near infrared light component, based on a result of the comparison.
