Abstract: PROBLEM TO BE SOLVED: To enable desired color reproduction by skillfully utilizing a standard color space whose color gamut is extended.
SOLUTION: As information for reproducing the color and gradation information of image data encoded by the standard color space, an image file read portion 51 reads a file of the image data attached with state information by the use of specific codes, representing a state into which representation of the colors and gradations of the image data is adjusted. A judgement portion 52 selects image data of a suitable image block, based on header information in a file header block, and moreover selects a suitable correction processing. A correction processing portion 53 applies the correction processing to the image data, and its result is temporarily held in a memory (RAM). A monitor display portion 55 performs processing for displaying the image data of the correction result. A printer output portion 56 performs processing for outputting the image data of the correction result to a printer driver to perform printing.

Abstract: PROBLEM TO BE SOLVED: To provide a technique adjusting white balance more accurately.
SOLUTION: A lightness detection section 19 detects a luminance value Y from R, G, B signals outputted from a white balance adjustment amplifier 17 as lightness. An exposure amount setting section 20 generates a control signal d for controlling a diameter D of an opening 12A of an iris 12 on the basis of the luminance value Y, and applies the control signal d to a drive section 21. A white balance correction amount setting section 22 generates a correction gain kg(d) on the basis of the control signal d for controlling the diameter of the iris. A white balance amplifier gain setting section 23 corrects the R, G, B signals outputted from an AGC amplifier 16 on the basis of the correction gain kg(d) to adjust the gain of the white balance adjustment amplifier 17. An amplifier 17G of the G signal is controlled by the correction gain itself. The above technique can be applied to digital video cameras, digital still cameras, and other image pickup devices.

Abstract: PROBLEM TO BE SOLVED: To provide an image processor for automatically generating an image with natural white balance the colors of which are close to those viewed by a viewer in a photographing scene.
SOLUTION: An amplifier gain setting section 161 estimates a light source parameter depending on the spectrum distribution of a photographing light source on the basis of an image signal. A tracking sensitivity setting section 162 modulates a first adjustment control variable of each color signal in the case of adjustment to take the white balance on the basis of the estimated light source parameter in a direction of a second adjustment control variable of each color signal in the case of adjustment such that an object in an achromatic color under a particular reference light source is reproduced in the achromatic color by an amount in response to tracking sensitivity and sets the adjustment control variable to WB amplifiers 14. The tracking sensitivity setting section 162 sets the tracking sensitivity to the amplifier gain setting section 161 in response to an illuminance level estimated from a detected value of lightness or the like.
