摘要： An edge enhancement circuit uses bandpass filters to separate an original video signal into low-, middle- and high-frequency band edge components which will be supplied to waveform shaping circuits. Each of the waveform shaping circuits detects an amplitude peak level of the edge component, generates a gain coefficient based on the peak level, and multiplies the original video signal by the gain coefficient. The results of multiplication are added together to generate a final detail signal. Thus, the edge enhancement circuit amplifies the amplitude of the edge component having a frequency approximate to the spatial frequency of the video signal to provide an edge enhancement based on a frequency characteristic corresponding to the spatial frequency of the video signal.
摘要翻译：边缘增强电路使用带通滤波器将原始视频信号分离成将被提供给波形整形电路的低，中，高频带边缘分量。每个波形整形电路检测边缘分量的振幅峰值电平，根据峰值电平产生增益系数，并将原始视频信号乘以增益系数。相乘的结果被加在一起以产生最终的细节信号。因此，边缘增强电路放大具有近似于视频信号的空间频率的频率的边缘分量的幅度，以基于与视频信号的空间频率相对应的频率特性来提供边缘增强。

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 imaging parameter recording apparatus and an imaging apparatus are disclosed. The setting states of various parts of an imaging system 1 at the time of imaging are detected by a system controller 9 and routed as imaging parameters to a recording/reproducing system 2. These imaging parameters are recorded along with the imaging data on a video tape 17. This enables not only the picture corresponding to the imaging data but also the imaging parameters at the imaging time to be reproduced at the reproducing time, so that not only the past setting state can be recognized, but also the past setting state can be newly set so that the picture of the same picture pattern can be imaged.

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.
