Image processing and printing apparatus
View Patent ↗An image processing and printing apparatus includes a processor that is configured to process image data to apply effects to the image data. Image data input circuitry receives image data for processing. A card reader reads a card having a two-dimensional code printed on one side of the card. The reader generates data representing executable code upon reading the card. The reader is connected to the processor to write the data to the processor, which executes the code and performs an image processing operation on the image data according to the code. A printhead interface is connected to the processor to receive processed image data from the processor and to generate print data. A printhead is connected to the printhead interface to print processed images.
1. An image processing and printing apparatus which comprises
a processor that is configured to process image data to apply effects to the image data;
image data input circuitry for receiving image data for processing;
a card reader for reading a card having a two-dimensional code printed on one side of the card, configured to generate data representing executable code upon reading the card, and connected to the processor to write the data to the processor, which is configured to execute the code and to perform an image processing operation on the image data according to the code;
a printhead interface connected to the processor to receive processed image data from the processor and to generate print data; and
a pagewidth inkjet printhead connected to the printhead interface to print processed images.
2. An image processing and printing apparatus as claimed in claim 1 , in which the image data input circuitry includes a memory which is connected to an image capture device to receive image data from the image capture device, the memory being accessible by the processor to write the image data to the processor.
3. An image processing and printing apparatus as claimed in claim 2 , in which the memory is a random access memory.
4. An image processing and printing apparatus as claimed in claim 3 , which includes a reader motor for propelling the card past the linear sensor at a substantially constant rate.
5. An image processing and printing apparatus as claimed in claim 1 , in which the card reader includes a linear sensor having a scanning resolution which is at least twice a resolution of the two-dimensional code on the card.
6. An image processing and printing apparatus as claimed in claim 1 , in which the processor is configured to detect, via the card reader, a data area on the card and subsequently to detect a bit pattern represented by the two-dimensional code in the data area.
7. An image processing and printing apparatus as claimed in claim 6 , in which the processor is configured to perform a decoding operation on the bit pattern to generate redundancy encoded data and then to decode the redundancy encoded data to generate the executable code.
