20080247001 | IMAGE PROCESSING SYSTEM AND IMAGE PROCESSING METHOD - An image processing system comprising: an image acquisition unit for acquiring a scanned image; a non-voltage storage medium that stores correction information corresponding to a known object having a three-dimensional shape defined by the standard; when an object of the scanned image is the known object, a correction unit that corrects a shadow area of the scanned image corresponding to a shadow resulting from thickness of the known object, on the basis of the correction information. | 10-09-2008 |
20110051152 | Image Processing Apparatus, Image Processing Method, And Program - An image processing apparatus includes: a reading unit; a counting unit; a cumulative value calculation unit; a cumulative value storing unit; and a print range determination unit, wherein the cumulative value calculation unit sets a value obtained by subtracting a predetermined value from the cumulative value, as the cumulative value, in the case where the number of pixels having a luminance equal to or smaller than a predetermined luminance value is not counted by the counting unit. | 03-03-2011 |
20110063638 | Image Processing Apparatus, Image Processing Method, And Program - An image processing apparatus includes a reading unit that reads image data; a counting unit; a non-cumulative counting unit; a non-cumulative frequency storing unit; a cumulative value calculation unit; a cumulative value storing unit; and a print range determination unit, wherein the cumulative value calculation unit does not change the cumulative value in the case where no pixel having a luminance equal to or smaller than a predetermined luminance value is counted by the counting unit, and the cumulative value calculation unit adds the number of pixels counted by the counting unit and subtracts a value corresponding to the frequency stored in the non-cumulative frequency storing unit to and from the cumulative value at that time point so that a resultant value is used as the cumulative value in the case where the pixels having a luminance equal to or smaller than a predetermined luminance value are counted by the counting unit. | 03-17-2011 |

20100238460 | SERIAL PRINTER - Provided is a serial printer including: a reading unit configured to read a raster image from a manuscript medium; an analysis unit configured to derive a horizontal distribution of pixels darker than a background color of the manuscript medium in each band including a predetermined number of lines with respect to the raster image; a threshold derivation unit configured to derive a fixed threshold according to a length L of a section in which a cumulative frequency of the horizontal distribution of an edge of the band does not exceed a predetermined temporary threshold; and a movement distance control unit configured to reduce the movement distance of a printing head according to a section in which the cumulative frequency of the horizontal distribution from the edge of the band exceeds the fixed threshold. | 09-23-2010 |
20110176189 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM THEREOF - Disclosed herein is an image processing apparatus comprising: a read unit that reads a target to be read as color data of N colors (N is a positive integer) that form a color space; a generator that generates pixel data of one pixel from the read color data of the N colors; a determining unit that determines whether the generated pixel data is present in an achromatic edge area that includes an achromatic edge; and a processing unit that, if the generated pixel data is determined to be present in the achromatic edge area, generates, for pixels in the achromatic edge area, achromatic pixel data of the color space from one item of the read color data of the N colors forming the color space and also generates image data from the generated achromatic pixel data. | 07-21-2011 |
20110194160 | IMAGE READING APPARATUS - A position of a leading edge of an original sheet should be accurately detected utilizing a shadow thereof, irrespective of thickness of the original sheet. In a scanner, an image sensor recognizes the shadow of the leading edge of the original sheet projected on a projection screen when a light source emits light to the original sheet being automatically transported on a glass plate. The original sheet is determined to have reached a reading position, when the original sheet is further transported by a predetermined distance after the shadow is recognized. The projection screen is located above the glass plate at a position spaced apart from the image sensor by a predetermined distance, and hence the timing that the shadow of the leading edge of the original sheet is projected on the projection screen is constant irrespective of the thickness of the original sheet. | 08-11-2011 |
