摘要： An imaging apparatus can obtain a high quality still picture imaging signal in the all pixels read out mode and output it by means of an output processing means adapted to the interlaced read out mode. The imaging signal read out from a CCD image sensor 23 in the interlaced read out mode is directly supplied to a DV recording/reproducing processing section 4 by way of a camera signal processing circuit 24. The imaging signal read out from said CCD image sensor 23 in the apparatus is converted into an interlaced signal by a scan conversion section 3A, which is then supplied to the DV recording/reproducing processing section 4.

摘要： Video signal processing apparatus for use with a video camera having a line scanning line period during which useful video information is provided and a flyback period during which an optical black signal level is provided. Replacement black signal information that is a function of the optical black signal level is inserted into a portion of the flyback period. When the camera is of the type having a complementary color matrix filter which produces odd and even raster scan lines of image pickup signals with different modulation components, another aspect of this invention provides improved contour correction. Modulation components in a scan line of image pickup signals caused by the patterns of filter elements included in the matrix are removed, thereby producing an averaged scan line of image signals from which is extracted a signal component that is uncorrelated from one line to the next. Prior to such extraction, that portion of an averaged scan line of image signals which exceeds a predetermined level that is less than the lowest average level of a scan line of image signals which would saturate video processing circuitry is clipped. The extracted, uncorrelated signal component is combined with an averaged scan line of image signals to produce a contour-emphasized luminance signal.

摘要： A luminance signal is formed from a first luminance signal produced by mixing a plurality of complementary color signals obtained from a television camera having complementary color filters and from a second luminance signal produced by mixing at a predetermined ratio a plurality of primary color signals that are derived from the plurality of complementary color signals, the first and second luminance signals are then mixed so that the composite output signal forms the desired luminance signal. The first luminance signal is level adjusted based upon the color temperature detection signal derived from a color temperature detector and a second luminance signal is balanced in level based upon this color temperature detection signal. The second luminance signal is derived by mixing the three primary color signals at a predetermined ratio. This ratio is variable and can be controlled in response to an automatic gain control signal derived from an automatic gain control circuit that receives the output of the television camera.

摘要： A signal processing circuit comprises an image sensor having an optical black level detecting portion, a buffer circuit for receiving an output signal from the image sensor, a clamping circuit for receiving an output from the buffer circuit, and a low-pass filter provided between the buffer circuit and the clamping circuit. This low-pass filter is made operative by a switching circuit in the interval responsive to the black level detecting portion in the output signal of the image sensor, while it is made inoperative in the interval responsive to the image pickup signal detecting portion. According to this circuit, the black level drift can be followed, thereby preventing the appearance of line noise on the screen without being influenced by the sag component due to the AC coupling.

摘要： A dot sequential color signal which is generated in an image pick-up means, as for example a CCD type image sensor is supplied to a first sampling and hold (S/H) circuit, with the frequency of the sampling pulse used in the first S/H circuit being at a predetermined frequency (FO), and the output of the first S/H circuit is supplied to a second S/H circuit, with the frequency of the sampling pulse used in the second S/H circuit being selected to be N times of the predetermined frequency (NFo), so that the frequency of the sampling noise caused by the sampling operation is relatively high compared with the output signal of the image pick-up means, and thus the cut-off frequency of a low pass filter for eliminating the sampling noise can be selected to be high enough not to attenuate the desired signal.
