摘要:
An information acquiring unit acquires information indicating whether a color material used at least for image formation is saved. An image-information generating unit creates, when the information acquiring unit acquires the information for saving the color material, image information using the color material of which consumption is saved.

A backlight unit having a LED light source includes a light guide plate partitioned in areas each having a tapered shape formed of a thick portion and a thin portion. The light guide plate is formed such that a thick portion and a thin portion are repeated at certain intervals, and the repeated thick portions and the repeated thin portions gradually decrease in thickness. The LED light source is attached to a lateral side of each thick portion. Grooves are formed in the light irradiation direction of the LED light source and in a direction perpendicularly intersecting the light irradiation direction. Each of the grooves is formed in an concave shape (V-shape or trapezoid-shape). There is a relation 0.2/30

摘要:
In a projection type display apparatus using plural light sources, an optical unit including plural light sources, a first collimator lens, an optical coupling lens, an image display element and a projection lens is formed, and in an optical path extending from the light sources to the projection lens, light is condensed only once on the image display element, thereby minimizing the number of optical parts used and shortening the length of the optical path from the plural light sources up to the projection lens to attain the reduction in size of the projection type display apparatus or the optical unit.In this way it is possible to provide a projection type display apparatus or an optical unit each capable of attaining the reduction of cost by minimizing the number of optical parts used and capable of attaining a high luminance by irradiating the image display element with the light emitted from the light sources without leakage of the light.

An image processing apparatus includes a first calculating unit that calculates a first feature amount from a color image signal, a first processing unit that processes the color image signal based on the first feature amount to generate a processed signal, a compressing unit that compresses the processed signal to generate a compressed signal, a storage unit that stores the compressed signal, a decompressing unit that decompresses the compressed signal to generate a decompressed signal, a second calculating unit that calculates a second feature amount from the decompressed signal, and a second processing unit that processes the decompressed signal based on the second feature amount. The second feature amount is multinary.
摘要:
A compact, light projection type image display apparatus based on reflection image display devices which provide high brightness without contrast deterioration caused by light leakage associated with black image display. The apparatus uses, as polarizers/analyzers for reflection image display devices, reflection polarizing plates which function as polarizing plates by their grating function only in a specific direction. In each light path, the reflection polarizing plate is located just before/after the reflection image display device.
摘要:
A projection type image display apparatus able to improve the utilization efficiency of light and attain a high luminance of light. An optical waveguide for guiding light emitted from a light source is provided, and a color separator for transmitting predetermined color light included in the light guided by the optical waveguide and for reflecting predetermined color light included in the guided light is also provided. The light reflected by the color separator is guided by the optical waveguide and is thereafter reflected by a reflecting member. The light reflected by the reflecting member is radiated into the optical waveguide and conducted thereby to the color separator.
摘要:
An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is caused when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combinations relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage device of a control unit. At least two or more sets of grouped information, including first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit.

A single plate type optical unit and display device to utilize light with high efficiency in a simple method is configured so a dichroic mirror separates light into a plurality of colors, and the plurality of colors of light reflected by the dichroic mirror are beamed onto a rotating multisurface element, the plurality of colors of light emitted from the rotating multisurface element are each beamed onto different locations on the display element, and by rotating the rotating multisurface element, the plurality of colors of light are moved in one direction along the display element, and a color image is beamed from a projection lens.
摘要:
A time point at which a predetermined period elapses since the start of use of a copying machine as a detection subject after factory shipment or repair is obtained. Pieces of set information, which are combinations of various types of information until the time point is reached are sequentially stored to construct a normal set information group. After the time point is reached, presence of abnormality in the copying machine is determined based on the normal set information group and the various types of information obtained.
