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.

摘要： For enabling to prevent ill effects from being generated in the structures of a reflection mirror, even if increasing an output energy from a light source, thereby preventing ill influences from being exerted on the driving condition thereof, a mirror drive controller unit 7 reads out history data of the past, relating to temperature changes on a micro mirror 1, from a first LUT holder unit 19. Upon basis of the read-out history data of the past is presumed the temperature on the micro mirror 1 at the present time. The presumed temperature on the micro mirror 1 is temperature P temp of the micro mirror 1 at the present time, and upon that P temp are changed vibration (or oscillation) condition of the micro mirror 1 in the horizontal (H) direction and vibration (or oscillation) condition thereof in the vertical (V) direction.

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.
