摘要： The present invention provides a method and an apparatus for converting a color image of a higher-resolution to an image of a lower-resolution. With the method of the present invention, based on characteristics of spatial frequency responses of the human visual system, a lower-resolution image (116) is formed by separating a higher-resolution image (72) into a luminance channel (76) and chrominance channels (98 & 100) so as to carry out suitable sampling and filtering for each of the luminance channel (76) and the chrominance channels (98 & 100), then by combing the luminance channel (86) and the chrominance channels (111 & 114) after the sampling. As to the chrominance channels (98 & 100), traditional sub-sampling (101 & 103) is carried out to avoid chromatic aliasing, while sub-pixel sampling (80) is performed for the luminance channel (76) to improve resolution of luminance component.

摘要： A display that includes at least one gray level being provided to a plurality of pixels that illuminates each of the pixels with the gray level. The display applies interpolated corrective data for the pixels so as to reduce the mura effects of said display for those characteristics generally visible by the human visual system and so as not to reduce the mura effects of the display for those characteristics generally not visible by the human visual system.

摘要： A method of field sequential color image capture includes optically capturing a scene; filtering the scene through an active color filter (84) to product first color components, thereby modifying the spectral transmission of the scene as a function of time; detecting the scene with a single, monochrome sensor (90) and dividing the scene into multiple second color components, whereby each first color component of the scene is detected at a different point in time; aligning the second color components in time for each frame interval; storing each color component in a memory unit; combining the stored second color components into a frame image; and processing the frame image for color reproduction and format. A system for capturing a field sequential color image, includes an optical capture mechanism for capturing a scene frame-by-frame in frame intervals; an active color filer (84) for producing multiple first color components; a single monochrome area sensor (90); an array field selector (92) for dividing the scene into multiple second color components; multiple memory locations for storing each color component; a field-to-frame combiner (118) for combining the stored second color components into a frame image; and a color reproduction processor (120) for processing the frame image for color reproduction and format.

摘要： PROBLEM TO BE SOLVED: To realize a sharp read image without causing any colored edge or blurring due to color mismatching. SOLUTION: This image read method using sensors placed on a plurality of rows and columns includes a step where the sensor on a row 32 reads a luminance component of the image with the 1st resolution and a luminance output signal is generated from the read luminance component, a step where a sensor on a row 34 reads an R component of the picture at an interval of one pixel with a resolution being a half of the 1st resolution, a luminance component of the remaining pixels of the image is read, an RY chromaticity output signal is generated from the read R component and luminance component, and a step where a sensor of the row 36 reads a B components of the picture at an interval of one pixel with a resolution being a half of the 1st resolution, a luminance component of the remaining pixels of the image is read, a BY chromaticity output signal is generated from the read B component and luminance component.

摘要： PROBLEM TO BE SOLVED: To improve the resolution of an saturated color text with a background in a bright color, and to improve the resolution by an arithmetic and efficient method. SOLUTION: This method includes a process for converting a color picture signal 32 into color picture signal components C1 and C2 and a luminance picture signal component L. A mask is generated for picture selection (for selecting whether a picture with prescribed picture elements is a text or a background) from the luminance picture signal component L. The color picture signal components C1 and C2 are respectively changed to new color picture signal components C1NEW and C2NEW by the mask. The new color picture signal components C1NEW and C2NEW and the luminance picture signal component L are converted into a new color picture signal 62 without any color unclearness.

摘要： PROBLEM TO BE SOLVED: To provide a color image reception system which receives images of three color planes with the full resolution of a sensor and uses only one sensor. SOLUTION: The system which receives field progressive color images receives a scene by an optical image receiving device by frames at frame intervals and generates many 1st color components by an active color filter 84. The scene is detected by a single monochromatic area sensor 90 and divided into many 2nd color components by an array field selector 92. The color components are stored in multiple memory locations, the 2nd color components which are stored are combined by a field frame coupler 118 into one frame image, and a color reproducing processor 120 processes the color reproduction and format of the colors of the frame image.
