An original pupil color of a subject person in an image in which an abnormality such as a red-eye or gold-eye occurs is estimated. Further, whether an image correction is required or not and to produce an image having a natural pupil color in the image correction by estimating the original pupil color from the image is judged. A pupil color estimating device has a skin color of a subject person specified from an inputted image, regardless of whether an abnormality such as a red-eye or gold-eye occurs. This skin color is substituted in an approximate equation based upon a statistical result carried out in advance, and thereby a normal color component of a pupil is estimated from the skin color of the subject person.

A normal light CCD 11 is driven via a normal light CCD control section 25 by a timing signal from a timing circuit section 29 of a video processor 20. At the same time, a fluorescence CCD 12 is driven via a fluorescence CCD control section 26. Then, an image pickup signal according to an RGB frame sequential method from the normal light CCD 11 is processed by a normal light image video circuit section 27 and a normal color image is created while an image pickup signal from the fluorescence CCD 12 is processed by a fluorescence image video circuit section 28, and an image pickup signal of a subject excited by blue illumination light and transmitted through a fluorescence transmitting filter 13 is extracted to create a fluorescence image of the subject. The normal color image and the fluorescence image of the subject are synthesized by an image synthesizing circuit section 30 and outputted to a monitor 2, whereby the normal light image and the fluorescence image is displayed side by side or on top of each other.

Enhanced dynamic range requires more than 8 bit representation for single color components of pixels. For this purpose, normal color resolution images and high color resolution images are available. Backward compatibility can be achieved by a layered approach using a color enhancement layer, and a conventional image as color base layer. Both have same spatial and temporal resolution. Encoding of the color enhancement layer uses prediction and residual. A methods for optimized color enhancement prediction is disclosed. Color bit depth prediction is done by constructing a polynomial that approximates for all pixels of one color component of a block the color enhancement layer from the color base layer. A predicted version of the high color resolution image and a residual are generated and updated by a residual. The coefficients are compressed and added as metadata to the data stream.

A video signal copy guard system in which a special color burst signal (or "copy prohibition signal") is inserted into the video signal to be copy protected so that the protected signal includes both a special color burst signal and a normal color burst signal. The special color burst signal is placed adjacent to the normal color burst signal, and its phase, frequency, and/or amplitude is varied with respect to the normal color burst signal. The special color burst signal interferes with the normal color burst signal when an analog VCR attempts to process the protected signal. Thereby, preventing unauthorized dubbing of the protected signal.

A V-LED, B-LED, G-LED and R-LED for an endoscope are all driven to apply normal light to an object of interest in a body. An image sensor images the illuminated object and outputs an RGB image signal. A measurement sensor measures a light amount of red light from the R-LED. A light source controller acquires a current value for the R-LED according to a light amount signal from the measurement sensor and a target light amount signal for the R-LED. A normal color converter and the R-LED receive a current of the current value. Each LUT_Mij in the normal color converter is referred to for outputting a matrix coefficient according to the current value of the R-LED. The RGB image signal is converted into a processed image signal by matrix operation according to the matrix coefficient.

An image forming apparatus includes a first image carrier forming a black toner image, a plurality of second image carriers forming a yellow, magenta, or cyan toner image, a third image carrier forming a special color toner image, and a transfer target member or an intermediate transfer belt. The apparatus further includes first and second detachment units. The first detachment unit detaches only the third image carrier from the transfer target member, and the second detachment unit detaches the second image carriers and the third image carrier. When switching from a special color image mode to either a normal color image mode or a monochrome image mode is performed during continuous printing of the recording media, the first detachment unit or the second detachment unit controls the detachment operation based on the number of recording media continuously printed by the normal color image mode or the monochrome image mode.

There is disclosed a display device using a color wheel having a color filter Cw, in addition to normal color filters corresponding to the three primary colors. The filter Cw has almost flat spectral transmission characteristics. Brightness information included in a color image signal is quantized with (n+m) bits. Information corresponding to the lower-order n bits is displayed by light transmitted through the filter Cw. Information corresponding to the upper-order n bits is displayed by light transmitted through the normal color filters. Only brightness information to which the human eye is visually sensitive is reproduced by the filter Cw having a lower transmissivity. This can eliminate a lack of the number of gray levels due to a constraint on the minimum switching speed of a light valve. Furthermore, the brightness little deteriorates.
