    摘要: A data transmission apparatus and a camera system for multiplexing serial data into horizontal blanking portions of video data for transmission between a CHU (1) and a CCU (2). On the transmitting side, resampled data is obtained by sampling the serial data using a clock signal of a frequency higher than that of the transmission rate of the serial data. A predetermined number of resampled data items are selected as multiplexing data from the resampled data obtained in each of the horizontal periods of the video data. The multiplexing data is multiplexed into the horizontal blanking portions of the video data for transmission. On the transmitting side, the multiplexing data is separated from the received video data. The separated multiplexing data is decoded so as to extract successively definite data constituting the initial serial data.

    摘要: An image signal generation portion 10 generates an image signal DVb of a variable frame-rate picked-up image whose frame rate can be varied. A frame rate conversion portion 30 converts a frame rate of an image signal DVu supplied to it into a frame rate of the image signal DVb and synchronizes them to provide an image signal DVw. A monitor image signal generation portion 40 uses the image signals DVb and DVw to generate an image signal DVmix of an image in which an image based on the image signal DVb and an image based on the image signal DVw are mixed and output it as a monitor image signal DMTout or SMTout. Alternatively, it generates an image signal DVwp of an image in which a part of an image based on the image signal DVb is replaced by an image based on the image signal DVw and outputs it as the monitor image signal DMTout or SMTout. It is possible to simultaneously display a variable frame-rate picked-up image and an image having a different frame rate.

    摘要: High frequency components of a video signal are attenuated for avoiding aliasing when the video signal is corrected by a non-linear gamma correction circuit. Such high frequency components arise from the video signal harmonics, and also are generated in image contour processing of the video signal. The high frequency components are band limited, thereby linearizing the gamma correction circuit and preventing aliasing. Up-converting the sampling frequency increases a desired band limitation area and defers the generation of high frequency components that cause aliasing. The non-linear gamma correction function is divided into a plurality of sections which are replaced by respective straight-line segments each represented by a linear expression, and gamma correction is effected with a straight-line segment corresponding to the amplitude of the digital video signal.

    摘要: It is intended to enable main image data from a video camera and background image data recorded on a recording medium to be chromakey-combined with each other naturally at a low cost. When a video switcher chromakey-combines main image data that is produced by imaging with a video camera with background image data that is reproduced from a magnetic tape by a VTR, the main image data is chromakey-combined with the background image data such that the VTR is caused to perform a reproducing operation on the magnetic tape based on time codes that are stored in a control device as one of a pair of information and the operations of the video camera and a video camera stage are controlled based on camera control information as the other of the pair of information.
