    摘要: Stochastic dithering may be used to reduce the size of the frame buffer and the complexity of the D/A Converters (DACs) in the drive circuitry that are used in a video display system. Hardware for stochastic dithering can be simplified when pixel data is presented in raster order. The hardware adds algebraic noise to the image to be dithered, and thresholds the result.

    摘要: An image recording apparatus with inexpensive data line resequencing circuitry for formatting image signals to a print head. The circuitry includes a resequencing line store device connectable to a data link and a control link for resequencing at least one first line of sequentially ordered data bits carried by the data link according to control signals carried by the control link. The resequencing line store device includes a plurality of interconnected memory cells operable for storage and selectable transfer of the data bits in response to the control signals, whereby the plurality of cells are arranged in a plurality of cell groups and a plurality of cell subgroups corresponding respectively to groups and subgroups of the bits. The bits may be shifted into the plurality of groups in sequential order and shifted from the plurality of cell subgroups in a non-sequential order corresponding to the first and second partitions.

    摘要: The present invention is an interface adapter circuit that allows multiple types of 256K by 16 bit dynamic random random access memories to be used by system manufacturers. The interface adapter circuit selects a type of outputs signal set to produce responsive to a mode selection signal. The circuit converts an input signal set including a column address probe and low and high by write signals into either a first output signal set, including one column address strobe and high and low byte write signals, or a second output signal set including a single write signal and high and low column address signals, responsive to the selection signal. The circuit includes a logic circuit for producing the signals and flip flops for holding the signal produced. The flip flops also synchronize other memory address, etc. signals with the signals produced by the adapter circuit. The interface adapter circuit can also convert write nd column address timing signals and low and high byte write signals into the two sets responsive to a selection signal.

    摘要: A first embodiment of the present invention provides logic to select between one of three or more user entered video standards and one or more selectable default video standards. The logic overrides the default standard with the user selected standard. A second embodiment includes a state machine that sets a mode output to a default standard from among two or more standards specified at the factory using jumper pins. The state machine can step through the two or more available standard modes, thereby changing the picture displayed to the user and, as desired, allowing the user to indicate what standard should be used.

    摘要: An LED printhead or the like includes a data bus for carrying multibit digital image data signals for grey level recording. A token bit signal is generated and shifted through registers upon the printhead to enable image data registers associated with each LED to latch the image data signals in appropriate order. The image data signals control the energization times for recording pixels. A digitally adjustable current mirror controls the level of current to each LED during recording. Digital current data signals for controlling this level of current are also communicated over one of the lines of the data bus. A token bit signal is also used to control the latching of current data signals in registers storing the digital data used for current control.

    摘要: Dye cartridge system adapted to reduce an exterior envelope of a printer and method of providing same. The printer comprises a housing having a front sidewall that has an aperture therethrough. A platen and a print head are disposed in the housing. The print head is movable from a first position spaced-apart from the platen to a second position adjacent to the platen, such that the platen and the print head define a clearance therebetween when the print head is in the first position. A dye donor cartridge carrying a dye donor ribbon is insertable through the aperture and into the housing to a position adjacent to the print head. A rod-shaped catch-member is attached to the end portion of the dye ribbon. Moreover, a dye ribbon take-up spool, which is permanently disposed in the housing has a recess therein for receiving the catch-member. When the catch-member is received in the recess and the take-up spool is rotated, the dye ribbon winds about the take-up spool. The neck portion is sized to be received through the clearance for interference-free insertion of the cartridge. In this manner, the cartridge may be loaded through the aperture in the front sidewall rather than by opening a top panel of the printer, so that the exterior envelope of the printer is reduced. This allows the printer to reside in a confined space with limited headroom.
