  • Patent number: 6313923
    Abstract: An operator can freely and easily designate a region, which the operator wishes to extract as an image to be outputted from an image, by designating the position and size of a region setting frame by using an enlargement/reduction handle. Accordingly, no carrier or mask is required for this purpose, and the number of parts required can be reduced. Operability at the time of cropping an image can also be improved greatly. Further, by operating rotation buttons and 90°-rotation keys, the operator can, with simple operations, rotate an image displayed as a test image and can freely and easily designate an image within the region setting frame, i.e., an image to be outputted.

  • Patent number: 6238105
    Abstract: Memory storage and memory bandwidth requirements of a color laser printer (or other printer having real-time printing constraints) are reduced by representing image information in a compressed format throughout the rendering process. At any one time during the rendering process, preferably, only a single scan line is expanded to the full, uncompressed format required for eventual printing. The rendered scan line is then recompressed and stored in memory. When all scan lines have been processed and are stored in memory in compressed format, the entire image is then expanded in real time and sent to the printer.

  • Patent number: 6229622
    Abstract: When a single user prints out a large quantity of printed matter in a situation where the printer is shared by a plurality of users, other users must wait an extended period of time regardless of the quantity of material which they are to print out. Accordingly, the inventive printer stores received print data upon classifying the print data according to independent spool areas that correspond to respective ones of the users. At printout, fixed quantities of data are printed from the respective spool areas in regular order. Even if there is a user printing out a large quantity of printed matter, other users who are to print out small quantities of printed matter need not wait for the end of the large printing job.

  • Patent number: 6215561
    Abstract: The image processing technique of the present invention prevents the deterioration of picture quality due to quantization errors caused by conversion of the tone number, which allocates image data to lattice points previously set in a color space. Pre-conversion of the tone number allocates original color image data to peripheral lattice points among the lattice points set by dividing the color space into lattices. The allocation of the original color image data to the peripheral lattice points causes quantization errors. The allocation, however, causes the mean error to be not greater than a predetermined value, in order to output desirable colors in a resulting image. The color space may be divided into smaller areas in a low-density range. This minimizes the deterioration of picture quality due to the quantization errors. A smoothing process carried out after the pre-conversion of the tone number relieves the effect of the quantization errors and further improves the picture quality.

  • Patent number: 6178008
    Abstract: An automatic system forms color LUTs (or LUT-forming data) for automated reference—typically in error diffusion (ED). A first aspect is for printers with six or more colorants. Three ramps, for different basic colorants, are photometrically measured; mainly just those results yield a transform from 3D color to system colorants. In a second aspect, some device-state candidate colors are chosen for black replacement. In a variant the choice is subject to (1) maintaining some chromatic colorant in each pixel with black; or (2) modifying use patterns to avoid alternative use of composite black vs. black; or (3) adjustments to allow for composite nonequivalence to black. A related third aspect allows replacement only if there is a given minimum amount of composite. In a fourth aspect, candidate states are dropped that have small changes in number of quanta per pixel, or no companion light colorant quantum with each dark one, best eliminating those with too many quanta of each or all colorants.

  • Patent number: 6175426
    Abstract: To print plural copies of a document consisting of a plurality of pages by a printer, a host computer sandwiches print data with a spool command and a spool end command, and transmits the print data to the printer. The printer stores the received print data, sandwiched in between the spool command and spool end command, in a spool area. Then, the printer processes the print data stored in the spool area similarly to the processing of print data received directly from the host computer. Note that in this case, the printing operation is repeated the number of times corresponding to the number of copies of the document designated by the host computer. Accordingly, print data stored temporarily in the spool area can be used in similar manner to the print data transmitted directly from the host computer, for printing plural copies of the document.

  • Patent number: 6172765
    Abstract: An information processing apparatus analyzes the objects contained in print data and creates index information consisting of the types of objects included in one job and on each page of the job, the numbers of the objects and the sizes thereof. The index information is sent to a printer together with print data. On the basis of the index information, the printer calculates the size of the image developed and the quantity of data before it performs printing. If the calculated image size and quantity of data conform to conditions decided from the memory size and printing speed of the printer, the print data is developed into an image the resolution and number of tones of which are less than those originally specified. This image is printed out.
