  • Publication number: 20220198635
    Abstract: A verification apparatus reads an image of a printed sheet using a plurality of imaging units to obtain image data. The verification apparatus extracts feature points of the obtained image data and determines whether a feature point of first image data obtained by a first imaging unit should be a feature point of second image data that should be obtained by another imaging unit. If so, the verification apparatus converts coordinates of the feature point of the second image data to a coordinate system of the first imaging unit, calculates a geometrical conversion parameter from the coordinates of the converted feature point and coordinates of feature points other than the converted feature point, and aligns the image data of the printed sheet and a correct image based on the geometrical conversion parameter.

  • Publication number: 20210303844
    Abstract: A verification apparatus comprises setting a feature point of a reference image as a verification target image, and a reference region of a predetermined pattern formed in advance on a recording medium on which the verification target image is to be formed; extracting the set feature point from a read image obtained by reading a formed image; specifying, based on a positional relationship between the set feature point and the reference region, from an image position of the extracted feature point, a first region on the read image, which indicates a region where the predetermined pattern should have been formed, and a second region other than the first region of the read image; and performing verification for the first region by a first algorithm, and verification for the second region by a second algorithm.

  • Patent number: 11099935
    Abstract: The present invention provides an information processing apparatus having a user interface, a non-volatile memory that stores a loading program, and another non-volatile memory that stores a boot program and a notifying program for notifying an error. The information processing apparatus executes the loading program at startup to verify the boot program and activates the notifying program based on a detection of an alteration of the boot program to notify an error via the user interface.

  • Patent number: 10510135
    Abstract: The present image processing apparatus mutually converts raster-order image data and block-order image data by dividing image data into a plurality of areas in units of bands, and performing reading-out and writing of the image data to one line memory in the units of bands of the division. The apparatus calculates, in the units of bands, an address increased amount, which is used for calculating an address to next write to or read out from, from an address that is a current processing target, calculates an address of a write destination when writing image data to the line memory and an address of a readout destination when reading-out image data from the line memory by adding the calculated address increased amount to an address value of a current processing target address.
