Abstract: A verification apparatus includes a reading unit configured to read an image of a conveyed sheet. The apparatus obtains a reference image for verification of a sheet, and extracts, from the reference image, feature points to be used for alignment of an image with the reference image. The apparatus aligns, with the reference image, a read image obtained by reading an image of a verification target sheet by the reading unit, and verifies the read image by comparing the aligned read image with the reference image. Based on a number of the feature points extracted from the reference image the alignment is performed using positions of the feature points or using positions of sheet vertices each indicating a corner of the sheet.

Abstract: A image forming apparatus acquires an amount of a printing material for image data of each page included in the print job formed from a plurality of pages; and transmits, to an image forming unit, image data of an Mth page included in the print job after transmitting, to a temperature control unit, information of the acquired amount of the printing material for the image data of the Mth page included in the print job. Particularly, when another job to be executed with a higher priority, the transmission unit transmits image data of a page included in the other job to the image forming unit after transmitting, to the image forming unit, the image data of the page corresponding to the information of the amount of the printing material transmitted to the temperature control unit.

Abstract: Since memory access is performed on a large number or discontinuous address regions, the performance of memory access is significantly degraded; in a system that performs high speed image formation, registration deviation cannot be corrected. Sub scanning position information corresponding to the profile of registration deviation is set, and image correction processing is divided into two stages, high resolution correction processing using line buffers formed with a memory which allows high speed random access and low resolution correction processing using a memory whose capacity is easily increased.

Abstract: An image processing apparatus includes a determination unit and a trap unit. The determination unit is configured to determine for each of a plurality of color plates whether trapping processing is performed at a position of a target pixel of an image divided to the plurality of color plates. The trap unit is configured to perform the trapping processing at the position of the target pixel for each of the plurality of color plates based on a determination result of the determination unit. In a case where the determination unit determines that the trapping processing is performed on a predetermined color plate, the trap unit does not perform the trapping processing at the position of the target pixel for the color plate on which the trapping processing is performed according to the determination by the determination unit.

Abstract: Correction for eliminating deformations of an image to be output from an image apparatus is executed while suppressing the processing load on the host computer side. A host computer acquires deformation information used to designate read addresses according to deformations of a scan line from a laser beam printer. A CPU (1) of the laser beam printer generates read addresses according to the deformation information to read out image data from a RAM, and transmits the readout image data to the laser beam printer. The laser beam printer (0) forms an image based on the image data received from the host computer (3000).
