  • Patent number: 11694421
    Abstract: An image processing apparatus includes an acquiring unit and an assigning unit. The acquiring unit is configured to acquire first image information on a first image and second image information on a second image read by irradiating, with light at respective different wavelengths for read, a printing medium on which at least the first image and the second image to be irradiated with light at different wave lengths to read are mixed. The assigning unit is configured to assign image information on one or more color systems constituting the first image information and image information on one or more color systems constituting the second image information to any of communication paths for supplying image information to a subsequent stage image processing unit configured to perform predetermined image processing on the first image information and the second image information.

  • Publication number: 20190384523
    Abstract: A control device for an image forming apparatus includes: a first transfer unit configured to read log data from a first memory and write the log data into a second memory; and a second transfer unit configured to read the log data from the second memory and transfer the log data outside the control device. The first memory is a volatile storage device and configured to store the log data acquired by a processor. The second memory is a volatile storage device. The first transfer unit, the second transfer unit, and the second memory are reset by a second reset unit other than a first reset unit configured to reset the processor and the first memory.

  • Patent number: 10158777
    Abstract: An image processing apparatus includes a memory, a correction circuit, and a calculation circuit. The memory stores image data of an original image that is moved in a sub-scanning direction with respect to an image sensor. The correction circuit sequentially reads the image data from the memory line by line in the main scanning direction, extracts a pixel in a position corresponding to the inclination, and forms an inclination-corrected line in the main scanning direction to correct the inclination. The calculation circuit calculates an amount of movement of a corner of the original image with respect to the sub-scanning direction before and after correction of inclination of the original image with respect to a main scanning direction. The correction circuit restricts progress of formation of the inclination-corrected line based on the amount of movement. The amount of movement is applied when the inclination of the original image is corrected.
