Abstract: 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.

Abstract: 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.

Abstract: A decoding section 111 decodes inputted coded data to image data and outputs it to an image data writing section 112 whenever necessary. The decoding section 111 outputs a decode completion notice signal to an image data reading section 114 and control signal generating section 115 every time when outputting a predetermined amount of image data (for example, an amount corresponding to one frame). The image data writing section 112 writes image data to the storing section 113 whenever necessary. An image data reading section 114 operates intermittently with timing when the decode completion notice signal is input thereto, and reads a predetermined amount of image data from the storage section 113. The control signal generating section 115 generates a control signal 206 that instructs a new portion in image data decoded by decoding means.

Abstract: 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.
