摘要： A color input image comprising a plurality of pixels, each pixels encoded in RGB color space, is processed to convert the RGB pixels to another color space domain for printing the color input image. The number of colors within a cell of the input image is reduced. Each cell comprises an N×M array of pixels and the number of colors is reduced to a maximum of b source colors, wherein b is a positive integer equal to or greater than 2. Each of the resulting colors of each cell is calibrated to generate a printable color. The cells are then processed to convert the pixels of each cell into another color space, for example, to determine ink vectors, in another color space, for each calibrated color.

摘要： A pulse width digital to analog converter is constructed which provides an output clock rate that is a multiple of the input sampling rate. In one embodiment a latch is used to store N-bit digital word representing the analog signal value to be generated. (N-K) of the most significant bits are stored in a counter which decrements its count in response to a clock signal. A plurality of least significant bits of said digital word stored in said latch are applied to a logic circuit. A ring counter is utilized to indicate which section of the output signal is currently being generated. The plurality of the least significant bits of the digital word stored in the latch, together with the output signals from the ring counter, are applied to said logic circuit, and the transition of the output signal of the digital to analog converter from a logical one to a logical zero is delayed, when required, to provide a slightly increased output pulse width in response to said plurality of least significant bits of said digital word, thereby maintaining or even increasing the resolution of the system.

摘要： An operational amplifier gain stage utilizing switched capacitor resistor equivalent circuits is designed utilizing a delayed clock reference signal (.phi..sub.D, .phi..sub.D) in a unique manner, thereby eliminating the effects of spurious error voltages (E.sub.S) generated when utilizing metal oxide silicon field effect transistors as switches (12, 15, 21, 23, 25). The single remaining MOSFET switch (21) which will contribute a spurious voltage component to the output of the operational amplifier gain stage is designed in such a manner as to minimize the spurious voltage generated during operation of the MOSFET switch. A single dummy switch (31) is utilized to further minimize the spurious voltage generated by this single MOSFET switch.
