This disclosure describes examples for foveation rendering. A graphics processing unit (GPU) may render image content for each tile at different sizes as part of the rendering pass after a binning pass in which the GPU determined to which tiles vertices of primitives belong. The GPU may upsample the rendered image content based on the size at which GPU rendered the image content, and output the upsampled image content for later display.

An image processing method is an image processing method of a recording device. The image processing method includes inputting the image data having a resolution in a sub scanning direction of X×N dpi, performing data processing on the image data for each N-unit region, performing resolution reduction processing of reducing, to 1/N, a resolution in the sub scanning direction, and generating a recording data based on the reduced image data. In the data processing step, when the N-unit region is formed of a pixel having a black gradation value and a pixel having a gradation value that is equal to or greater than a predetermined value when expressed by RGB, and the pixel having the black gradation value is consecutive from another N-unit region adjacent to the N-unit region, a black dot is generated in a pixel after the resolution reduction processing.

A method of digital printing is disclosed in which a digital image to be printed has at least one region having pixels comprising superpositioned layers of a first ink and a second ink. The method includes producing at least one sample print and calibrating misalignment of the superpositioned layers at a plurality of calibration locations on the sample print. The resultant misalignment data is provided to a morphing program to determine a pre-deformation of the digital image to compensate for misalignment during printing. An apparatus and a machine-readable storage medium comprising instructions executable by a processor are also disclosed.

An image forming apparatus includes a scanner configured to read an image of a document and generate image data of the image according to a reading mode, a storage device configured to store the image data and the reading mode used when reading the image of the document, and a processor. The processor generates a combined image that includes the image of the document and a reading direction image that indicates a reading direction of the scanner and has a shape indicating the reading mode, and store data of the combined image in the storage device. The processor determines a position of the reading direction image in the combined image and a size of the reading direction image in the combined image, based on a reading resolution of the scanner and a resolution of the image data stored in the storage device.

A method and apparatus are provided for changing scan settings to verify the size of a scanned document. The method includes displaying on a user interface of the apparatus, a size of the scanned document, scanned based on one or more scan settings. The method further includes receiving a user response relating to the size of the scanned document. The user response is indicative of whether the size of the scanned document is according to a target size. The apparatus provides at least one of color information or resolution information to at least one of a device associated with the user or the user interface, when the size of scanned document is greater than the target size. The user changes one of color and resolution settings. The method includes scanning the document with one of changed color or resolution settings to obtain the scanned document with the target size.

An image judgment apparatus stores, in a memory, a judgment model configured to learn about each of the plurality of judgment items based on first data corresponding to an image as a reference with which to judge good and second data corresponding to an image as a reference with which to judge not good, sets a plurality of magnifications for each of the plurality of judgment items, segments part of the image, generates image data at the plurality of magnifications from the segmented image, inputs the generated image data corresponding to each of the plurality of magnifications to the judgment model, and judges, based on output results from the judgment model, whether the quality of the image is good or not good with respect to each of the plurality of judgment items.

A system and method for printing large files from a memory constrained mobile device analyzes image files to determine whether decompressing them for display or printing would result in image data exceeding device capacity. If not, the image data is displayed on the device and sent to a printer. If so, metadata in the image files is altered such that image data is generated at a lower resolution before decompression for displaying and printing.

A printing device may include two printers for printing to the front side and the back side of a recording medium. The physical page length of at least one print image applied onto the front side of the recording medium is determined. The required page length of at least one print image to be applied onto the back side of the recording medium is adapted to the determined page length. At least one print line of the print image for the back side is printed repeatedly if the required page length for application of the rear print page onto the back side of the recording medium is smaller than the determined page length.

A image processing method includes a shifting step for determining whether to shift an identical color pixel region, in which two to N pixels of an identical color are arranged consecutively in a first direction, in the first direction or a direction opposite to the first direction within the image data, provided that N is an integer of 2 or greater, and shifting the identical color pixel region in the first direction or the direction opposite to the first direction when the shifting is determined to be performed, and an averaging step, in which in the shifting step, the shifting is determined to be performed when the identical color pixel region exists across two of the unit regions, and the identical color pixel region spanning across the two of the unit regions is shifted so as to be included in any one of the unit regions.
