摘要： A digital camera processing system with software to manage taking photos with a digital camera. Camera software controls the digital camera. A downloaded software component controls the digital camera software and causes a handheld mobile device to perform operations. The operations may include instructing a user to have the digital camera take photos of a check: displaying an instruction on a display of the handheld mobile device to assist the user in having the digital camera take the photos; or assisting the user as to an orientation for taking the photos with the digital camera. The digital camera processing system may generate a log file including a bi-tonal image formatted as a TIFF image.

摘要： The present invention provides an image data conversion device that can convert color image data to black-and-white image data suitable for a background image. One example embodiment of the present invention is an image data conversion device that represents color image data in gray scale to convert the color image data to black-and-white image data and that includes determination means for determining whether or not the black-and-white image data is data used for a background image; and image data conversion means for converting the color image data to black-and-white image data using brightness values ranging from a background image minimum brightness value to a maximum brightness value when the black-and-white image data is data used for a background image.

摘要： A binary image of an input image is generated, and a character region within the binary image and a region surrounding each character are acquired as character segmentation rectangle information. A thinning process is executed on a region within the binary image which is identified based on the character segmentation rectangle information to acquire a thinned image. An edge detected image of the region identified based on the character segmentation rectangle information is acquired. Whether each character identified based on the character segmentation rectangle information is a character to be separated from a background by the binarization process or not is determined based on a result of a logical AND of the thinned image and the edge detected image.

摘要： An image reading apparatus includes a gray reference member, a reading unit, an adjusting unit, a calibration unit, a storage unit, and a control unit. The control unit is configured to execute a first preprocessing and a second preprocessing. The first preprocessing includes: acquiring first black data from one line worth of image data; acquiring white data; calculating white-black difference data; acquiring first light gray data; and calculating first light gray-black difference data. The second processing includes: acquiring second black data from the one line worth of the image data; acquiring second light gray data; calculating second light gray-black difference data; calculating a change ratio by dividing the second light gray-black difference data by the first light gray-black difference data; and calculating calibration data by multiplying the white-black difference data by the change ratio.

摘要： An image processing apparatus specifies pixels other than a white pixel which are included in a window, the window including a target pixel and pixels in the vicinity of the target pixel in a scanned image. Thereafter, the image processing apparatus averages color values of the specified pixels other than the white pixel, and then determines whether the target pixel is a color pixel based on a color value obtained by the averaging.

摘要： An image processing device includes a detector that detects a target pixel as an outline pixel if a density of a predetermined region including the target pixel with each pixel of an image treated as the target pixel is equal to or above an outline determination threshold value, the outline determination threshold value being a threshold value set in response to the density of the target pixel, and being a threshold value used to determine whether the target pixel is an outline pixel corresponding to an outline of the image, and a correction unit that corrects a correction pixel, as a correction target having a density equal to or above a predetermined density from among the outline pixels detected by the detector, in response to a density of the correction pixel.

摘要： A smoothing method extracts an evaluation window including a target pixel of a multi-value image data in which tone is represented by a multi-value in units of pixels, and judges black and white of the target pixel according to a predetermined rule, and binarizes pixel data within the evaluation window. Further, the smoothing method generates a correction value based on collating binarized pixel data within the evaluation window and a look-up table which stores patterns in vicinities of the target pixel, and outputs a multi-value correction signal in which the correction value is converted into a multi-value.
