ABSTRACT:
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.
