An image signal processorinputs digital picture datainto a compressorand into a resolution changerin parallel. The compressoroutputs compressed data, which is compressed digital picture data, to an outputthrough a buffer. Meanwhile, a resolution changeroutputs the new digital picture data, which is the digital picture datawith reduced resolution, to the output. In accordance with the instruction of a selection signal, the outputselectively outputs either one of digital picture datawith reduced resolution and the buffered compression dataas output datathrough the same signal line at the same signal timing. By this means it is possible to provide a camera apparatus which can simplify circuit configurations of external apparatus that receive digital picture data and compression data and simplify the circuit control.

Picture quality on a display screen is corrected in accordance with a change either in image information or in the light state. The electronic apparatus includes a display panel, a lighting means for lighting the display panel, a parameter adjusting means for adjusting a parameter participating in picture quality so as to conform the light state while using variations in the light state of the lighting means as a trigger, a signal correcting means for inputting a display signal and correcting the input display signal in accordance with the adjusted parameter, and a driving means for driving the display panel on the basis of the corrected display signal. The light state is controlled according to the content of a file containing the information to be displayed.

In a moving picture decoding display apparatus and moving picture decoding display method according to the present invention, moving picture decoderdecodes a moving picture signal, RGB matrix manipulation sectionconverts the decoded video signal in YCbCr format into a video signal in RGB format, contrast/brightness adjusting sectionadjusts the contrast and brightness of the video signal in RGB format, and liquid crystal display module sectiondisplays the adjusted video signal on liquid crystal panel. At this point, operation control sectionswitches on and off the operation of RGB matrix manipulation sectionand contrast/brightness adjusting sectioncorresponding to the actual frame rate in moving picture decoder, and only when the operation is 'on', the sectioncontrols so that the video signal from contrast/brightness adjusting sectionis stored in video RAMin liquid crystal display module section. Thus, since the operation of required video signal processing is switched on and off based on the actual frame rate, it is possible to suppress the power consumption in the entire apparatus.

Moving picture decoding display apparatus and method for controlling a video signal's contrast and brightness when a video signal update is detected

A vertical region designation circuitoutputs a vertical region designation signal to a vertical driveron the basis of vertical display position information, a vertical synchronization signal and a horizontal synchronization signal. A horizontal region designation circuitoutputs a horizontal region designation signal to a horizontal driveron the basis of horizontal display position information, a pixel synchronization signal, a vertical synchronization signal and a horizontal synchronization signal. The horizontal driveroutputs an input picture signal to a picture display surfacefrom a signal line at a horizontal coordinate corresponding to the number of times of pixel synchronization signals that is counted from an input horizontal synchronization signal as a starting point during a period when a horizontal region designation signal is effective. A vertical driverstores the number of times of synchronization of a horizontal synchronization signal during a period when a vertical region designation signal is effective, and the vertical driverselects a signal line at a vertical coordinate corresponding to the number of times of synchronization. The picture display surfacedisplays a picture signal output from the horizontal driverat a position designated by a horizontal coordinate corresponding to the signal line where the picture signal was output and a vertical coordinate corresponding to the signal line selected by the vertical driver

A signal generating apparatus generates four sets of signals whose rising timing and falling timing are controlled. One signal among the four signals is produced by employing a first sequence control unit, a first coincidence detecting unit, a second coincidence detecting unit, and a first output controlling unit. A timer increments a count value in response to a timer increment signal to produce a timer output value. The first sequence controlling unit produces two correction values obtained by correcting the timer output value inputted from the timer. The first coincidence detecting unit outputs a coincidence detection pulse when the correction value inputted from the first sequence control unit is coincident with the internally set set value. The second coincidence detecting unit outputs another coincidence detection pulse when the correction value inputted from the first sequence control unit is coincident with the internally set set value. The first output controlling unit controls the rising timing of the signal in response to the coincidence detection pulse inputted from the first coincidence detecting unit, and also controls the falling timing of the signal in response to another coincidence detection pulse inputted from said second coincidence detecting unit.
