  • Patent number: 10530961
    Abstract: A copying apparatus capable of calibrating a copy position comprises a scanning module scanning an original to obtain an original image; and a processing module being electrically connected to the scanning module and recognizing whether the original image contains an original mark corresponding to a template mark. If the original image contains the original mark, then the processing module generates print data for being printed out according to the original image and a position parameter of the template mark. A copying method capable of calibrating the copy position is also provided. Thus, the copy position can be calibrated according to the mark of the original to prevent the copy result from having a positional offset. Consequently, no positional offset occurs even if the original is copied multiple times based on the previous generation of original.

  • Patent number: 10257383
    Abstract: An image processing apparatus includes an image processing device. The image processing device includes a receiving port and a processor connected together. The receiving port receives old image data corresponding to a document image of a document. The processor divides the old image data into first area image data corresponding to a first area image of the document, and second area image data corresponding to a second area image of the document, and further performs image enhancement processing on the first area image data to obtain enhanced first area image data. Thus, the first area image may be separated from the second area image, and the image enhancement processing is performed on the first area image. The enhanced first area image data and the second area image data are separately outputted or combined for output.

  • Patent number: 9955039
    Abstract: An image processing device comprises a receiving port, a processor and an output port. The receiving port receives old image data from a peripheral device. The old image data has partial positioning mark data corresponding to a portion of a positioning mark of a document, and partial main image data corresponding to a partial main image of a portion of a main image of the document. The processor electrically connected to the receiving port shifts the partial main image by a calibration distance in a calibration direction to a standard position of a typesetting page according to the partial positioning mark data and the partial main image data, and adds a predetermined image to one side or neighboring two sides of the partial main image to generate new image data. The output port electrically connected to the processor outputs the new image data. Copy apparatus and method are also provided.

  • Publication number: 20180013908
    Abstract: An image processing device comprises a receiving port, a processor, a storage and an output port. The receiving port receives old image data from a peripheral device. The processor electrically connected to receiving port performs a judging process on the old image data. When an old information block of the old image data is judged as containing old copy generation-count information, the processor generates a new information block containing new copy generation-count information according to the old copy generation-count information, and subtracts the old information block from the old image data and adds the new information block thereto to generate new image data and an encoding record. The storage electrically connected to the processor stores the encoding record. The output port electrically connected to the processor outputs the new image data. Copy apparatus and method using the image processing device are also provided.
