摘要： A natural white balance is achieved in images that are captured while emitting a flash. The white balance of an image is adjusted using a WB adjustment portion and a mixture ratio calculation portion estimating a mixture ratio of an external light component and a flashed light component that are present in an image captured with emitting a flash, from the image obtained that is captured while emitting a flash and an image signal that is obtained without emitting a flash. Further, an external light WB coefficient determination portion determines an WB coefficient for the external light, a flashed light WB coefficient setting portion sets a WB coefficient for the flashed light, and a WB processing portion that continuously performs WB processing on the image captured while emitting a flash by using the mixture ratio as an interpolation ratio.

摘要： An imaging apparatus for capturing a moving image performs backlight correction of an image and outputs a natural image. The imaging apparatus electronically captures an image of a subject. An optical system has a light amount adjustment function. An imaging unit reads an optical image of the subject that is formed by the optical system. An A/D converter subjects an output of the imaging unit to A/D conversion. A backlight correction unit converts the tones of an image read by the A/D converter using a conversion characteristic selected differently according to a spatial position and at least increases the luminance level of a dark region of the image. An instruction unit instructs to start backlight correction. A control unit operates the backlight correction unit based on an instruction signal output from the instruction unit, and decreases an exposure light amount of the optical system by a predetermined amount.

摘要： The first color gamut conversion unit 102 limits, in a visually natural manner, an output signal to a signal within a range of the DCI color gamut through well-known color gamut conversion processing when there is a color region exceeding the DCI color gamut, the output signal being obtained through the imaging by the imaging unit 101 and represented by the primaries (R, G, and B) determined by a color filter of an image sensor of the camera. It is to be noted that a color gamut conversion technique may be any technique which can limit a color gamut such as gamut conversion processing (Non Patent Literature: “Fundamentals of Color Reproduction Engineering”, Corona Publishing Co., Ltd., pp. 178-180).
