摘要： In reading an image of a document in a monochromatic reading mode, a document reading apparatus reads the image of the document while conveying the document at a speed determined according to a magnification ratio, executes digital magnification on the read multivalued image in a main scanning direction by using a main scanning direction magnification unit, binarizes the multivalued image, and stores the binary image on a memory. In reading an image in a color reading mode, the document reading apparatus reads the image of the document while conveying the document at a predetermined speed, stores the read multivalued image on the memory, and executes digital magnification on the multivalued image in the main scanning direction and a sub scanning direction.

摘要： A method for optimizing a selection of spectral sensitivities for an imaging device includes determining a first set (52) of spectral sensitivities from an initial set (50) of spectral sensitivities based on an analysis of one of a universal measure of goodness (52), a mµ-Factor (54), and RMS noise (56). A second set (54) of spectral sensitivities from the first set of spectral sensitivities based on an analysis of a different one of a universal measure of goodness, a mµ-Factor, and RMS noise. The second set of spectral sensitivities is an optimized set of spectral sensitivities.

摘要： A n-channel TFT (L) (26) which is connected to a transparent pixel electrode (24) and a p-channel TFT (D) (27) which is connected to the cathode side of a photodiode (25) are connected to a common source line (22) and a common gate line (23). When a positive voltage (VL) or a negative voltage (VD) are applied to the gate line (23), both the TFTs can be independently controlled to be in a ON-state. A backlight (18) which is provided on the rear of an active matrix panel (13) has monochromatic light sources (18a - 18c) emitting red, blue and green lights, and images of the colors are displayed in a time-division manner. When the images are read, by using the monochromatic light sources (18a - 18c) successively, the red, blue and green component images are read for every pixel. Only the parts of a liquid crystal layer (14) corresponding to every other pixel (P1) in the vertical and horizontal directions are brought into light transmitting states, a certain amount of charge is stored only in the photodiodes (25) of the pixels (P1), and the photodiodes (25) are exposed to light. Then the image formed by the pixels (P1) is read. The similar processes for the pixels adjacent to the pixels (P1) are repeated to read the image of the original for all the pixels.

摘要： An imaging apparatus includes an image sensor (208) having a plurality of color sensor arrays (302,304,306). Individual sensor arrays include a plurality of sensors (401,402,403) configured to provide image data for a plurality of pixels (308,310,312) of a respective color component at an initial resolution. The plurality of color sensor arrays overlap and are offset with respect to one another to define a plurality of sub-pixels for individual ones of the pixels. The imaging apparatus (100) includes processing circuitry (122,222) configured to access the image data for at least one pixel from each of the plurality of color sensor arrays, and using the accessed image data, to determine sub-pixel image data for the respective sub-pixels to form an image of an increased resolution compared with the initial resolution of the color sensor arrays.

摘要： A photosensor array has at least one row of photosensors (100, 102, 104) (200, 202, 204) with a first sensor size, and at least one row of photosensors (106) (206, 208, 210) with a second sensor size, with the two sizes being different. In a first example embodiment, each sensor in a row of sensors for white light (106) (206, 208, 210) has a smaller area than the sensors in other rows. For the first embodiment (figure 1), the native input sampling rate for luminance is greater than the native input sampling rate for color information. In a second example embodiment (figure 2), for every band of wavelengths being sensed, there are two rows of sensors, with one row having relatively small sensor areas and the other row having relatively large sensor areas. In the second example embodiment, the rows with relatively small sensor areas are used for high native input sampling rates, and the rows with relatively large sensor areas are used for high color accuracy.

摘要： The invention provides for a method of sharpening an image to be sent to a printhead. The method includes the steps of receiving an RGB (red, green, blue) data set indicative of the image, and deriving an initial luminance channel from the received data set. The method also includes the steps of sharpening the initial luminance channel to form a revised luminance channel, and incorporating the revised luminance channel into the data set.
