摘要:
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.

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 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.

A projection-type video display apparatus has a polarizing beam splitter for matching light, which is outputted by a light source unit, to one of S polarizing light and P polarizing light, an optical characteristics switching element for electrically and periodically switching a wavelength band of light outputted by the polarizing beam splitter, a video display element, as a light valve element, for forming an optical image from light outputted by the light source unit, in accordance with a video signal, and a radiating unit for radiating a plurality of color light, which are sequentially outputted by the optical characteristics switching element, to the video display element, wherein light outputted by the video display element is incident on a projecting lens, and a light path from the light source unit to the projecting lens is U-shaped. Consequently, the projection-type video display apparatus becomes compact and has improved contrast.
摘要:
A recording medium conveyance failure occurrence predicting apparatus predicts an occurrence of a conveyance failure of a recording medium conveyed in a conveyance path in an image forming apparatus including a recording medium conveyance member that conveys the recording medium while moving and contacting the recording medium, and a separation portion where the recording medium is separated from the recording medium conveyance member. The recording medium conveyance failure occurrence predicting apparatus includes a recording medium abnormal separation detecting unit that detects an abnormal separation of the recording medium from the recording medium conveyance member, and a determining unit that predicts an occurrence of a conveyance failure of the recording medium in the separation portion based on a detection result of the recording medium abnormal separation detecting unit.
