Abstract: PROBLEM TO BE SOLVED: To increase processing speed by executing conversion of a drawing command acquired from a PC or the like into an intermediate language by parallel processing. SOLUTION: The printing device includes: an intermediate language code generation unit 120 that acquires a drawing command and printing data written in a page description language and converts it into an intermediate language code; an intermediate language processing unit 130 that processes the intermediate language code generated by the intermediate language code generation unit 120 to generate raster data; and a printing mechanism 200 that performs printing processing based on the raster data generated by the intermediate language processing unit 130. The intermediate language code generation unit 120 divides the drawing command into units of blocks, i.e., that are pairs of drawing operators that designate images and graphic state operators that designate settings for drawing images, based on a dependence between blocks of the operators, and performs parallel processing for each of the divided blocks to generate the intermediate language code.

SOLUTION: The display panel 11 comprises: an information display area 12 for presenting information; and a color correction area 13 facing a color sensor to display an image for color correction. A display controller 41 transmits processed image data or the like from an input image signal to an X-driver 21 to display an image on the information display area 12. A false STB signal generation circuit 51 receives various kinds of clock signals and falsely generates an STB signal. Further, an STB2 signal provided by adding a false STB signal to an STB(strobe) signal generated by the display controller 41 is supplied to the X-driver 21. The false STB signal supplied to the X-driver 21 plots an image plotted on the last horizontal line of the information display area 12 onto the color correction area 13. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To maintain low noise by means of a main loop with a low loop gain at the time of locking and to obtain a wide frequency acquiring band by the sub-loop of a high conversion gain controlled by a one chip microcomputer. SOLUTION: The oscillation frequency of VCO 50 is prescribedly frequency- divided by a variable frequency divider 14 and phase-compared with a H-Sync signal by a phase comparator 18. A phase comparing output is fed back to a variable capacitor Cf 54 for fine control through a charge pump 30 and LPF 34 to constitute the main loop. As one with small dC/dV is used for the variable capacitor Cf 54, the loop gain is low and the influence of noise is hardly received. On the other hand, for a variable capacitor for coarse control Cc 52, one with satisfactorily large dC/dV is used. At the time of unlocking, a microcomputer 10 changes the output of D/A converter 66. As the conversion gain of a coarse oscillation circuit is large, the oscillation frequency changes large. At the time of not being locked after waiting the acquisition time of the main loop, this processing is repeated again.
