摘要： A document type recognition apparatus includes an image region separation unit, a smoothing unit, an edge enhancement unit, a histogram creation unit, and a document type recognition unit. The image region separation unit outputs a signal indicative of each region obtained by separating an input image into a character region and a pattern region. The smoothing unit performs smoothing processing to remove halftone dots of a particular number of lines or greater in the pattern region of the input image. The edge enhancement unit outputs an image subjected to edge enhancement processing depending on an amount of edge on an edge portion of the character region in the input image subjected to the smoothing processing. The histogram creation unit creates a histogram of the image subjected to the edge enhancement processing. The document type recognition unit recognizes a document type of the input image by utilizing the histogram.

摘要： An image processing device includes a resolution reducer, a detector, and a corrector. The resolution reducer generates, from an input image, low resolution images for pixel shift display being lower in resolution than the input image. The detector detects portions of the low resolution images corresponding to a specific pattern in which image quality degradation may occur. The corrector performs specific correction processing to reduce the image quality degradation on the portions of the low resolution images corresponding to the specific pattern.

摘要： A projector using coherent light as a light source includes: one or more coherent light sources emitting coherent light beams; a beam scanner which changes a direction of the coherent light beam; and a beam splitter which splits a beam into multiple segments and changes a phase of light of each split segment, the beam splitter being located in an optical path between the beam scanner and the coherent light source. This projector reduces speckle noises. The beam splitter includes a pair of transparent substrates; a plurality of parallel electrodes disposed on each surface of the pair of transparent substrates, the pair of the parallel electrodes being disposed in a perpendicular direction to each other. Voltages are applied to the respective electrodes at predetermined time intervals so as to produce different potentials in a liquid crystal sandwiched by the transparent substrates.

摘要： An objective of the present invention is to enable making a liquid crystal display device thin, and to enable regional control of window brightness with power conservation. A backlight of a liquid crystal display device comprises a plate-shaped light guiding plate (20). Recesses (21) are formed on the light guiding plate (20), and LEDs (30) are housed in the recesses (21). The LEDs (30) further comprise light emitting faces (301) and rear faces. The rear faces of the LEDs (30) are brought into contact with the interior walls of the recesses (21) of the light guiding plate, and light that leaks from the rear faces of the LEDs (30) is proactively used. A resin (25) for optical coupling is positioned between the LEDs (30) and the interior faces of the recesses (21). Using the light from the rear faces of the LEDs (30) allows reducing the number of LEDs that need to be lit, allowing obtaining a liquid crystal display device with minimized power consumption.
