  • Publication number: 20070047827
    Abstract: A data compression apparatus includes a thinning section that thins numerical values from a succession of values constituting compressed data to create first and second compressed data; a reversible compression section for the first compressed data; a detecting section that detects an edge portion of the image; and a non-reversible compression section that processes the second compressed data based on a result of the edge detection. When the detecting section detects no edge portion, the non-reversible compression section outputs a predetermined code of a number of bits. When the detecting section detects the edge portion, the non-reversible compression section outputs a first value based on image numerical value when involved with a predetermined positional relation expressed by a first number of bits and a second value expressed by a few number of bits than the first number when the image numerical value is not involved with a predetermined positional relation.

  • Patent number: 7003031
    Abstract: A PWM signal is made to rise synchronously with a pixel clock by inputting of a pulse to a set terminal (S terminal) of an R-S flip-flop. One of a reference clock, which is generated by a reference clock generator, and a delay clock, which is obtained by a delay circuit delaying the reference clock, is selected in accordance with delay selection data. The PWM signal is made to fall synchronously with a selected clock.

  • Publication number: 20050163387
    Abstract: According to a data compression apparatus for compressing data such as image data, there is determined a difference between adjacent numerical values on the continuity of numerical values constituting data to be compressed. Of the numerical values appearing in the difference data, only the numerical value “YY” is encoded. There is performed such a coding that a continued number Z of the numerical value “YY” is expressed with different bit numbers in accordance with Z<128 or z?128. In the coding, when data to be compressed is concerned with the binary data represented by only two sorts of numerical values, there is created new data to be compressed, which consists of continued numerical values represented by a unit bit number, in such a manner that the two sorts of numerical values are discriminated in one bit and the continuity of the one bit is expressed for unit bit number on a batch basis, and the created new data is transferred to the first data compression section.

  • Patent number: 6538523
    Abstract: When a PWM signal is generated by PWM generators which are provided for the number of channels, each PWM generator outputs the PWM start schedule data showing the timing of startup of the PWM signal to the CPU. When the number of PWM signals which start at substantially the same time exceeds a predetermined number on the basis of the PWM start schedule data, the CPU outputs delay setting data with respect to a channel corresponding to a portion exceeding the predetermined number to the PWM generator as the one showing that the generation of the PWM signal is to be delayed. The PWM generator delays the PWM signal, when the delay setting data shows a delay. As a result, a multi-channel pulse width modulation apparatus which can prevent a decrease in the operational reliability due to simultaneous start of the pulse width modulation signals can be provided.
