摘要： An image processing apparatus includes an image-data acquiring unit, a character recognition processing unit, and a monochrome conversion unit. The image-data acquiring unit acquires image data representing an image including a character. The character recognition processing unit performs a character recognition process on the image data to extract a character region. The character region is a region where the character is represented. The monochrome conversion unit converts the image data into monochrome image data when the image data is color image data including a color image. The monochrome image data includes a monochrome image representing the color image with a single color. When a tone difference between the extracted character region and an adjacent region is smaller than a predetermined threshold, the monochrome conversion unit changes a tone of a boundary region between the character region and the adjacent region adjacent to the character region.

摘要： A function which can be executed by an application is determined from information obtained from data obtained within a standard rule, thereby implementing a function within the standard rule. More specifically, processing executed by a scanner is recorded in EXIF information, and the application determines a function to be executed, based on the EXIF information.

摘要： Techniques for removal of interference patterns from digital images are described, in which a spatially-adaptive filter is applied to a pixel based on a context of the pixel. In an example, an edge of an object in a digital image is located in a digital image creation system. Then, context data is generated for a pixel in the digital image. The context data includes a distance from the edge of the object to the pixel. The digital image creation system can also generate color data and luminance data for the pixel, representing a similarity of color and luminance between the pixel and surrounding pixels within the digital image. Then, the digital image creation system constructs a spatially-adaptive filter for the pixel based on the context data for the pixel. The digital image creation system removes an effect of the interference pattern at the pixel in the digital image by applying the spatially-adaptive filter to the pixel.

摘要： An image processing device includes a reception unit and a generation unit. The reception unit receives an input image signal, and a synchronization signal used to generate an output image signal on a basis of the input image signal. The generation unit generates, in a case in which the reception unit receives an initial synchronization signal of a unit of image reading, a synchronization signal for a subsequent input image signal. The reception unit receives the synchronization signal generated by the generation unit.

摘要： An information processing method includes determining, in a luminance image that represents luminance components of an input image obtained by capturing a document image, a shaded region affected by shade and a specific pixel region including specific pixels less affected by the shade through a color of an object in the document image by using the luminance components of pixels of the luminance image, and generating a shade image that represents shade components of the input image by referring to pixel values of pixels adjacent to the specific pixels and repeating replacement processing of replacing a pixel value of each of the specific pixels with a value of the shaded region adjacent to the specific pixel until the specific pixel region disappears.

摘要： Systems and methods are disclosed for content aware digital image enhancement. In particular, in one or more embodiments, the disclosed systems and methods analyze content of a digital image portraying a document with graphics and/or text and generate a cleaning confidence map. Specifically, in one or more embodiments, the disclosed systems and methods generate a cleaning confidence map indicating a likelihood that each pixel in the digital image portrays text or a graphic. Moreover, in one or more embodiments, the disclosed systems and methods utilize the cleaning confidence map as a reflection of how aggressively to modify digital images. In particular, in one or more embodiments, the disclosed systems and methods utilize the cleaning confidence map to remove shadows, identify and clean background pixels, and correct contrast in relation to the digital image.
