  • Patent number: 8866923
    Abstract: A modular camera and printer is disclosed. A camera module is provided having an image sensor for capturing an image in a RGB format. The camera module also has a central processing unit with program memory for storing program steps for execution by the central processing unit to operate the camera module, and an image storage memory for storing the captured image in the RGB format. An image processing unit of the camera module is in communication with the image storage memory and transforms image data in the image storage memory into a L*a*b* format. The camera module also has a serial bus for outputting transformed image data in the L*a*b* format. A printer module is provided also having a serial bus in communication with the serial bus of the camera module. The printer module receives the image data from the camera module in the L*a*b* format, converts the image data to a color space of the printer module, and then prints the image data on a printhead.

  • Patent number: 8393703
    Abstract: A method of generating half tone print data is disclosed. The method starts by determining an extent of overlap caused by temperature variations of overlapping end portions of a pair of consecutive printhead segments. A dither value is also generated from a dither matrix, and the dither value is combined with the extent of overlap to produce an output value. A mathematical operation is performed on continuous tone print data based on the output value, to produce the half tone print data.

  • Patent number: 8272708
    Abstract: An inkjet printhead has nozzles and respective heater elements. A print engine controller actuates the heater elements to eject ink through the corresponding nozzle. During use, the print engine controller actuates each of the heater elements at least once every decap time. The decap time is a predetermined time period in which the viscosity of the ejectable liquid at the nozzle increases to a threshold, at which ejection fails and the nozzle clogs.

  • Patent number: 8270023
    Abstract: A print engine controller for a pagewidth inkjet printer includes an interface for connection to an input data bus to receive page data to be processed prior to printing. A data bus is connected to the interface to communicate data to various circuitry components of the controller. A memory is connected to the data bus and is configured so that as one page is loaded another previously loaded page is read from the memory to permit the controller to act in a double-buffered manner. A print engine pipeline is connected to the data bus and is configured to read the page data from the memory and process the page data into a form suitable for printing by the pagewidth inkjet printer.
