    摘要: Image de/coding unit 801 decodes coded image data and stores the image data on a temporary basis. Image address bus 123 and image data bus 124 connect image de/coding unit 801 and image display section 901. Image display section 901 stores image data like moving images in frame memory 914 which is a preexisting circuit, and displays the images that are for specified areas and that are produced in image de/coding unit 801 and previously produced images stored in frame memory 914 in overlap. By this means, it is possible to reduce the traffic on MPU (Micro Processor Unit) busses and to present large-volume image data such as moving images by relatively simple additions of functions.

    摘要: An image signal processor 12 inputs digital picture data 101 into a compressor 13 and into a resolution changer 16 in parallel. The compressor 13 outputs compressed data 102, which is compressed digital picture data 101, to an output 14 through a buffer 17. Meanwhile, a resolution changer 16 outputs the new digital picture data 104, which is the digital picture data 101 with reduced resolution, to the output 14. In accordance with the instruction of a selection signal 108, the output 14 selectively outputs either one of digital picture data 104 with reduced resolution and the buffered compression data 105 as output data 106 through 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.

    摘要: A vertical region designation circuit 141 outputs a vertical region designation signal to a vertical driver 103 on the basis of vertical display position information, a vertical synchronization signal and a horizontal synchronization signal. A horizontal region designation circuit 142 outputs a horizontal region designation signal to a horizontal driver 102 on the basis of horizontal display position information, a pixel synchronization signal, a vertical synchronization signal and a horizontal synchronization signal. The horizontal driver 102 outputs an input picture signal to a picture display surface 101 from 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 driver 103 stores 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 driver 103 selects a signal line at a vertical coordinate corresponding to the number of times of synchronization. The picture display surface 101 displays a picture signal output from the horizontal driver 102 at 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 103.

    摘要: 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.

    摘要: In a moving picture decoding display apparatus and moving picture decoding display method according to the present invention, moving picture decoder 101 decodes a moving picture signal, RGB matrix manipulation section 103 converts the decoded video signal in YCbCr format into a video signal in RGB format, contrast/brightness adjusting section 104 adjusts the contrast and brightness of the video signal in RGB format, and liquid crystal display module section 110 displays the adjusted video signal on liquid crystal panel 109. At this point, operation control section 105 switches on and off the operation of RGB matrix manipulation section 103 and contrast/brightness adjusting section 104 corresponding to the actual frame rate in moving picture decoder 101, and only when the operation is “on”, the section 105 controls so that the video signal from contrast/brightness adjusting section 104 is stored in video RAM 107 in liquid crystal display module section 110. 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.
