Abstract:
1. An image sensing apparatus comprising: an image sensing device which outputs a single output image; a first color temperature detection device which detects color temperature information of the single output image by averaging achromatic data extracted from the single output image; a second color temperature detection device which detects color temperature information of an ambient light by a color sensor which does not use the single output image; a calculation device which calculates a ratio of a presence amount of the achromatic data used to be averaged for the color temperature information detected by the first color temperature detection device to an entire presence amount of single output image data; a generation device which generates weighted color temperature information by weighting the color temperature information of the single output image and the color temperature information of the ambient light so that the weighted color temperature information becomes closer to the color temperature information of the ambient light as the ratio becomes smaller; and a white balance control device which controls white balance of the single output image by using the weighted color temperature information generated by said generation device.
