摘要： An imaging apparatus comprises: a color separation optical system for separating an image ray into blue, green, and red image rays, image sensors, having pixels vertically and horizontally arranged, for receiving the image rays and producing blue, red, and green signals wherein at least one of image sensors for blue and red signals has a vertical relative offset against the image sensor for green signal to have a relative interlace relation with the image sensor for blue or red color signal, to produce a screen to be produced, having a higher resolution than these image sensors. A vertical high frequency component is operated from the blue and red signals and is added to the green color signal to produce a second green signal indicative of a green luminance value at a position corresponding to each pixel of the image sensors for blue and red color signals to increase the vertical resolution of the screen. A fourth image sensor for green and a separation optical system for the fourth image sensor may be provided to increase a horizontal resolution by arranging the fourth image sensor to have a horizontal offset to have a second relative interlace relation with the image sensor for green. The image sensor for blue and red may have a vertical offset to eliminate the necessity of a field memory to operate the vertical high frequency component.

摘要： A noise reducing system for a video signal comprises a vertical pre-emphasis circuit supplied with an input video signal which is to be transmitted, for supplying an output signal to a transmission system, and a vertical de-emphasis circuit supplied with the video signal which has been pre-emphasized in the vertical pre-emphasis circuit and has been transmitted through the transmission system. The vertical pre-emphasis circuit has a characteristic for relatively emphasizing the level of high-frequency components of the input video signal having spatial frequencies in a vertical direction of a picture, compared to low-frequency components of the input video signal. On the other hand, the vertical de-emphasis circuit has a characteristic for relatively attenuating the level of the high-frequency components of the pre-emphasized video signal having spatial frequencies in the vertical direction of the picture, compared to the low-frequency components of the pre-emphasized video signal. The characteristics of the vertical pre-emphasis circuit and the vertical de-emphasis circuit cooperate so as to reduce noise having high spatial frequencies in the vertical direction of the picture.

Thereby, the receiving system can stably perform synchronous detection and bit synchronization on the basis of these turning points. Further, the capability of detecting address errors can be improved or increased and omission of the address error can be decreased.

The noise reduction circuit comprises first and second subtracting circuits supplied with the reproduced video signal from the reproducing circuit, a one-field delay circuit for delaying an output of the first subtracting circuit by a predetermined time period and for supplying a delayed signal to the second subtracting circuit, which predetermined time period is equal to one field or a time period which is a natural number multiple of one horizontal scanning period and is extremely close to one field, and a limiter for amplitude-limiting an output of the second subtracting circuit and for supplying an amplitude limited signal to the first subtracting circuit. The output of the first subtracting circuit is obtained as an output of the noise reduction circuit. The one-field delay circuit has a transmission band which is narrower than a band of the reproduced video signal.
