    • A CAM (content addressable memory) device capable of flexibly coping with a wide range of user requirements with respect to operation speed and/or power consumption has operation mode setting means, generates a higher or lower internal voltage than an external power-supply voltage depending on the setting, and at least part of the internal circuit is operated by the internal voltage. In particular, the high level of the search-bit line and/or the high level of the match line are preferably set to the internal voltage. Also, the CAM device has bit line amplitude adjusting means for adjusting the amplitude of the bit line depending on the setting of the operation mode setting means and/or match line amplitude adjusting means for adjusting the amplitude of match line on which a search result is output, and thus is capable of appropriately changing the operation speed and power consumption depending on the setting.

    • Digital image signals in each small block of m.times.n picture elements are read out from a first image memory, which stores the digital image signals for one screen, to be stored in block memories BM1Y, BM2Y, BM1C and BM2C, and the electric zoom processing together with the interpolation operation for the digital image signals in each small block are carried out in a zoom block. A picture element in the horizontal direction in a small block partially overlaps a picture element in a small block which is next to the above-mentioned small block in the horizontal direction. As a result, the interpolation processing in the horizontal direction can be also carried out on the boundary of the small blocks. And, the order to read out the digital image signal from the first image memory and the order to write the digital image signal in the block memory are changed so that the longitudinal-lateral conversion and the right-left conversion of an image can be carried out. Furthermore, in the zoom block, the contour correction for the digital image signal in the vertical direction is performed in accordance with the digital image signal in each small block, which has been zoom-processed.

    • A system is provided for producing image signals of a photographed subject image by a solid state image sensing device and for producing a brightness signal and line sequential color difference signals from the image signal. The subject image is sensed by the image sensing device which has a color filter formed thereon. First and second horizontal scanning lines of picture elements are alternately arranged and the picture elements are opposed to filter elements of the color filter. The first horizontal scanning lines separately transmit at least red light and green light and the second horizontal scanning lines transmit at least blue light and green light, to thereby obtain color image signals. The image signal thus obtained are signal processed to produce the line sequential color difference signals R-Y and B-Y. With this signal processing, the system can produce the image signals including the line sequential color difference signals by a simplified arrangement without impairing the color productivity.
    • 提供一种用于通过固态图像感测装置产生拍摄对象图像的图像信号并且用于从图像信号产生亮度信号和行顺序色差信号的系统。 被摄体图像由其上形成有滤色器的图像感测装置感测。 图像元素的第一和第二水平扫描线被交替布置,并且图像元素与滤色器的滤色器元件相对。 第一水平扫描线至少分别发送红光和绿光,第二水平扫描线至少发射蓝光和绿光,从而获得彩色图像信号。 由此获得的图像信号被信号处理以产生行顺序色差信号R-Y和B-Y。 通过该信号处理,系统可以通过简化的布置产生包括行顺序色差信号的图像信号,而不损害色彩生产率。
