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.

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： An imaging system capable of easily and reliably adjusting the functions provided in the camera device and preventing mistaken adjustment of these functions. At a step S255, a specified parameter of a definition file or a user file is deleted or changed in values. A CPU judges whether or not an effective key is pressed. If the key is found to be pressed, the CPU proceeds to a step S256 and, if otherwise, the CPU dwells at a step S255. At a step S256, the CPU reads out image data of a parameter setting window from a disc drive based on the selected parameter or the definition file prevailing at a time point of pressing of the effective key. The CPU writes image data of the parameter setting window in a VRAM and causes a display image corresponding to the image data to be displayed on a display.

摘要： The invention provides a technique of making color adjustment for a great number of colors among different imaging apparatus. In the process of making color adjustment among a plurality of cameras, a color correction processing unit disposed in a CCU of each camera detects data associated with lightness, hue, and saturation for a plurality of specified colors. The detected data is transmitted as color data to a CPU. According to the color data supplied from each CCU, the CPU divides the color space into a plurality of areas, and calculates setting data which is required by the color correction processing unit to correct the lightness, hue, and saturation. The resultant setting data is transmitted to the color correction processing unit. In actual use in a normal operation mode, the color correction processing unit corrects the lightness, hue, and saturation according to the procedure determined for each area in accordance with the setting data.
