摘要： A white-balance adjusting apparatus includes a CPU. The CPU integrates R, G, B and Y signals of a subject image on the basis of each of divisional areas of N in number, to determine integration values Rn, Gn and Bn on primary color components and an integration value Yn on a luminance component. Furthermore, the integration values Rn, Gn and Bn are converted into chrominance components. From the chrominance components, integration values RYn and BYn are determined that are removed of a Y component. Meanwhile, a table is written with a numeral “8” related to a monochromatic color and a numeral “1” related to a skin color. The CPU calculates optimal gains &agr; and &bgr;, based on the integration values Rn, Gn and Bn, integration values RYn and BYn and table. The optimal gains are given to the R, G and B signals thereby suppressing the skin color component of the subject image from changing.

摘要： A white balance compensation method enabling highly accurate image white balance compensation is conducted by a white balance compensation system. Digital image data acquired by a data acquisition unit is sent to a mean value computing unit that effects a computation on color signals B, G and R which are n-th powers of incident light intensity to calculate mean values Bm, Gm and Rm thereof as: Bm=((&Sgr;Bp/n)/M)n/p Gm=((&Sgr;Gp/n)/M)n/p Rm=((&Sgr;Rp/n)/M)n/p where p is a coefficient of the power n falling in the range of 0.5≦p≦1.5, preferably in the range of 1.0≦p≦1.5. The mean values Bm, Gm and Rm are sent to a conversion means that converts the color signals so as to make two of the mean values other than a selected one coincide with the selected mean value, thereby enabling reproduction of a white-balance compensated image free of color failure.

摘要： A photographic image-capturing element that receives a subject light flux and outputs a photographic image signal and a white balance adjustment image-capturing element that receives the subject light flux and outputs a white balance adjustment image signal are provided. Based upon the white balance adjustment image signal, color data are extracted from at least partial area in the photographic image plane to calculate the distance between the color data and a full radiator locus, i.e., the offset quantity by which the color data are offset from light source reference color data. The color of the light source is estimated by evaluating the offset quantity thus calculated, an R gain and a B gain are calculated in correspondence to the estimated value and a white balance adjustment is performed on the photographic image signal using these gains.

The characteristic difference between the color filters is suppressed, and, as a result, flickers are suppressed from being generated.

摘要： An automatic white balance adjustment system including a color signal reproduction circuit having a white balance adjustment section, a picture tube drive circuit, a picture tube, a cathode voltage detection circuit, a storage circuit, and a control circuit. The cathode voltage detection circuit detects a cathode voltage applied to a red cathode electrode, a cathode voltage applied to a green cathode electrode, and a cathode voltage applied to a blue cathode electrode of the picture tube. In the storage circuit, there are stored in advance comparison reference values set for the RGB primary color signals in order to control the RGB primary color signals so as to achieve a white balance in a given ratio. When detection pulses of predetermined IRE values corresponding to the respective RGB primary color signals are output from the picture tube drive circuit, the control circuit reads the red cathode voltage, the green cathode voltage, and the blue cathode voltage, all being detected by the cathode voltage detection circuit. Then, the control circuit compares the thus-read detection voltages with the corresponding comparison reference values stored in the storage circuit so as to correspond to the respective RGB primary color signals, to thereby control the white balance adjustment section of the color signal reproduction circuit such that the detected voltages coincide with the comparison reference values.

摘要： In a method for controlling color temperature a projection television having green, blue and red image projectors and a projection screen, holographically improving color shift performance of the screen results in an undesirable controlled input angle characteristic that attenuates images projected thereon at horizontal viewing angles of a few degrees from an axis orthogonal to the screen. Projecting blue images along an optical axis orthogonally aligned with the projection screen and projecting green and red along respective optical axes converging toward the orthogonally aligned optical axis makes it possible to energize the blue and green image projectors at substantially equal energy levels when producing a white image on the screen. The resulting white image has a bluer but acceptable color temperature than when the green images are projected along the optical axis orthogonally aligned with the projection screen and the blue image projector is energized at a higher energy level than the green image projector.

摘要： The present invention provides an image processing apparatus for reducing the light-dark contrast between a main subject and a background when an image photographed by a camera or the like using an electronic flash is read optically. An image portion corresponding to a wall as a background, where the light amount is reduced, and an image portion corresponding to a person are separated from each other. Only the wall image portion is sampled, the decreased light amount thereof is corrected (addition is carried out) on the basis of the photographing distance to the wall and the light distribution characteristics of the electronic flash, and the light-darkness contrast between the wall image portion and the main subject image portion can be reduced. As a result, image quality can be improved, and an appropriate photographic image can be taken even with an inexpensive and simple camera such as an LF.
