Abstract: An arithmetic processing section executes an arithmetic process on a flicker correction signal output from a flicker correction signal outputting section and corresponding to the flicker component contained in a video signal of each of specific periods and the video signal of each of the specific periods to form a corrected video signal of the specific period corrected for the flicker component of the specific period for the video signal of each of the specific periods formed as a succession of specific periods and containing a flicker component as supplied from a video signal generating section in response to a correction error signal of each of the specific periods supplied from a correction error detecting section.

Abstract: A video-signal-processing device has luminance conversion section that performs level compression on three input primary-color signals of a color video signal at a same luminance adjustment compression ratio with a hue and a saturation of the color video signal being kept constant, thereby generating three compressed primary-color signals. The device also has saturation conversion section that performs level conversion on the three compressed primary-color signals by using a saturation compression ratio if a maximum level of at least one of the three compressed primary-color signals exceeds a first level. The saturation conversion section sets the saturation compression ratio by using a minimum level one of the three compressed primary-color signals.

Abstract: A preprocessor performs a signal processing operation by using an image signal DVa generated by picking up a subject image. A frame adder adds frames of an image signal DVb generated by the preprocessor so as to generate an image signal DVc with a changed frame rate. When changing the setting of the signal processing operation of the preprocessor, the signal processing operation is restarted with the new setting at the start or at the end of a frame addition period (in units of frame addition periods) of the frame adder based on a determination signal indicating the frame addition period.

Abstract: 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.

Abstract: An image shooting unit 21 generates an image signal DVb having an image shooting frame rate. A main line image processing block 40 performs frame addition on the image signal DVb having the image shooting frame rate, and generates a main line image signal having a desired output frame rate. Based on the image signal DVb, a monitor image processing block 50 generates a monitor image signal having a frame rate independent of the frame rate of the main line image signal. Since the frame rate of the main line image signal and that of the monitor image signal are independent of each other, shooting an image while varying the frame rate of the main line image signal allows a monitor image at an image shooting time to be displayed at a predetermined frame rate using the monitor image signal DVr.

Abstract: An image signal generator generates an imaging signal having a frame rate that is controlled to be variable. A frame rate converter generates a monitor image signal. Upon receiving communication information from an external source, a controller controls the operations of the image signal generator and the frame rate converter on the basis of the communication information. When an instruction to specify the frame rate of the monitor image signal is given from a user interface, the controller controls the frame rate converter to generate a monitor image signal having a specified frame rate by giving priority to this instruction over the communication information.

Abstract: 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.

Abstract: An image shooting unit 21 generates an image signal Spa having an image shooting frame rate. A frame addition unit 41 performs frame addition on the image signal DVb having the image shooting frame rate. Control unit 61 controls drive unit 71 and the frame addition unit 41 based on a frame rate setting signal RSF from operation unit 62, and controls a variation of the image shooting frame rate in image shooting unit 21 and/or a switch of the number of additive frames in the frame addition unit 41, thus allowing an image signal DVj having a desired frame rate to be output from the frame addition unit 41. Thus, increasing the additive frame in number even without decreasing the image shooting frame rate at a low-speed shooting of the image allows such an image signal DVj shot at the low speed to be obtained.

Abstract: An image pickup device picks up an image. An image signal in association with the image is filtered in a time axis direction using a digital low-pass filter to generate an image signal having a reduced dynamic resolution power, which is equivalent to an image signal that would be obtained at a longer exposure time. The filtered signal is then subjected to frame skipping processing to generate an output image signal having a preferred frame period. The resultant signal is equivalent to one obtained by a slow shooting.

Abstract: A video camera system capable of matching colors between configured video cameras by effectively reducing color differences therebetween. A red, a green and a blue signal from imaging devices are amplified by preamplifiers and video amplifiers before being fed to a color matching circuit. The color matching circuit performs color matching in accordance with the levels of the red, green and blue signals using variables of gains and DC offset values. The gains and DC offset values are determined by the color matching circuit executing predetermined operation expressions. With a plurality of colors imaged in advance by the video cameras to be matched in color with a reference video camera, necessary coefficients of the operation expressions are obtained by use of the level measurements (tristimulus values) of the red, green and blue signals from an integrating circuit of each camera.
