    摘要： In an image pickup device which uses infrared, there are cases where, for example, if the infrared wavelength is mixed into the signal processing of the colors of visible light, the color balance changes and color reproducibility cannot be correctly reproduced. The present invention provides an image pickup device provided with the following: an image pickup section that picks up an image of a subject and that is sensitive to at least the red range, green range, and blue range of visible light, and the infrared range; an extraction region processing section that sets regions in an image picked up by the image pickup section; an infrared extraction processing section that extracts infrared range signal information from each of the regions of the image that were set by the extraction region processing section; a visible light extraction processing section that extracts visible light range signal information from each of the regions of the image that were set by the extraction range processing section; a white balance processing section that conducts white balance processing on the image using a prescribed color gain; and a system control section that controls the white balance processing section. The image pickup device is characterized in that the system control section, in accordance with the infrared signal information and visible light information extracted from each of the regions of the image, performs control so that the color gain of the white balance processing section is a prescribed value.

    摘要： Even in a case of photographing a photographic subject in which contrast between light and shade is large, a suitable color image is generated. An image sensor (102) includes a plurality of pixels on which three types of filters (R, G, B) which selectively transmit light having different wavelengths and have transmittances equal to each other in a visible light region and a clear filter (C) in which a transmittance of the visible light region is expressed by a linear sum of the transmittances of the filters (R, G, B) and which has a transmittance equal to the transmittances of the filters (R, G, B) in a near-infrared light region are arranged, and outputs a first output signal (S 1 ), an output signal linear-transforming part (104) transforms the first output signal (S 1 ) into a second output signal (S 2 ) having linearity, a color signal-generating part (105a) generates color signals by interpolating lacking color signals, an infrared-separating part (1053a) separates a near-infrared light component from the color signals and generates infrared-separated color signals, a luminance signal-generating part (107) generates a luminance signal (Y 1 ) from the first output signal (S 1 ), and a color-luminance-combining part (109) combines the infrared-separated color signals and the luminance signal (Y 1 ) and generates video signals (R 2 , G 2 , B 2 ).
