Abstract: An image forming apparatus includes an image forming unit and a controller. The image forming unit forms an image on each medium with a metallic toner. The controller controls the image forming unit such that, in the formation of an image on each medium of plural media different in reflectance, the metallic toner has a toner weight according to the medium.

Abstract: An image processing device includes an accepting unit, and a conversion information generating unit. The accepting unit accepts items of read data in a device-dependent color space that are generated by reading color patches, items of reference data in a device-independent color space of the color patches, and items of specific color component data each indicating a specific color component in a corresponding one of the color patches. The conversion information generating unit generates conversion information reflecting the presence or amount of a specific color component included in each color patch as information for converting input data in the device-dependent color space to output data in the device-independent color space, on the basis of the items of read data, the items of reference data, and the items of specific color component data.

Abstract: An image processing apparatus includes a calculation unit and a white layer density determination unit. The calculation unit calculates, based on multiple color component signals to be used for image formation, an image layer halftone percentage of an image layer to be formed on a recording medium. The white layer density determination unit determines, based on the image layer halftone percentage, a white layer halftone percentage of a white layer to be formed as an underlying layer of the image layer on the recording medium.

Abstract: A processor for an electronic endoscope, which is configured to be connected with a videoscope adapted to generate a picture signal for an image of an observed object through color adjustment using color adjustment data and to transmit the generated picture signal to the processor, the processor includes a light source configured to emit light for illuminating the observed object, a determining unit configured to determine whether the color adjustment data used by the videoscope is adapted to the light source, a color conversion data acquiring unit configured to acquire color conversion data adapted to the color adjustment data when the determining unit determines that the color adjustment data is not adapted to the light source, and a color converter configured to perform color conversion for the picture signal transmitted by the videoscope using the color conversion data acquired by the color conversion data acquiring unit.

Abstract: A light source apparatus, configured to introduce light into an endoscope connected thereto, includes a housing, a plurality of light sources supported movably relative to the housing, the light sources being configured to emit light, a light introducing unit configured to introduce, into the endoscope, the light emitted by an intended one of the light sources which is located in such a position that an optical axis thereof corresponds to an optical axis of the light introducing unit, a detector configured to detect a misalignment between the optical axis of the light introducing unit and the optical axis of the intended light source, and a light source moving unit configured to move the intended light source to such a position that the optical axis of the intended light source corresponds to the optical axis of the light introducing unit when the misalignment is detected by the detector.
