  • Publication number: 20050094008
    Abstract: RGB image data outputted from an ADC (3) is processed in an SPU (42) and an RPU (43) and then buffered into a memory (48) as YUV image data. The YUV image data is outputted from a YUV output unit (45), encoded by an image compression and expansion chip (5A) and transmitted to a main chip (4) by a DMAC (52). On the other hand, compressed moving image data stored in the memory (48) is transmitted to the image compression and expansion chip (5A) through the control by a DMAC (44), decoded therein, then converted into RGB image data in an RGB sampling unit (54) and inputted to the main chip (4) by the SPU (42) through a data line (14). With such a construction, it is possible to provide a circuit for compression and expansion, which allows connection with a main processing chip having no YUV input circuit without increasing circuit scale, maintaining general versatility of those circuits.

  • Patent number: 6873365
    Abstract: Any complicates pulse waveform required depending on the type of CCD, can be generated with a simple circuit configuration. Specifically, any complicated pulse is obtainable by inputting an unlimited number of toggle timings, with no limitation imposed on the number of toggle timings inputted. This is achieved only by inputting different toggle timings sequentially from the exterior, because the toggle timing of toggle circuits (14 to 16) is regulated by shift registers (12a, 12b) of a loop structure and comparators (11a, 11b) connected to the rearmost stage of their respective shift registers (12a, 12b).

  • Publication number: 20040201758
    Abstract: First pixel data of a pixel of interest is output from a first shift register, while second and third pixel data of neighboring pixels indicative of the same color are output from second and third shift registers, respectively. Differential data between estimated pixel data calculated from the second and third pixel data and the first pixel data is input to a comparator. A threshold value stored in a register is modulated by the estimated pixel data, and is input to the comparator as modulated threshold data. When the comparator judges that the differential data is greater than the modulated threshold data, a selector outputs the estimated pixel data as corrected pixel data.

  • Publication number: 20040105016
    Abstract: In image input devices such as digital still cameras, processing is speeded up and power consumption is reduced by arranging in a RPU (23) performing real time processing of a pixel data from a CCD (21), such that only special exceptional image processing not being prepared previously is subjected to a software program processing in a CPU (24) and, in post processing in which a general image processing is carried out, a pixel data temporarily stored in a main memory (29) is inputted again to the RPU (23) and then processed. This enables to sharply speed up processing, and minimize a prolonged processing in the CPU (24) to reduce power consumption, when compared to the case of executing by software problem processing.
