Abstract: A color imaging apparatus which produces a luminance signal and a plurality of chrominance signals in order to generate a composite color video signal which is capable of compensating a color reproduction characteristic in response to a variation of the color temperature of the incident light. A signal representative of the color temperature of the light is used to control the gain of the color difference signals and/or control the phase difference between a plurality of color subcarriers on which the chrominance signals are modulated. The color temperature signal can be produced from a white-balancing circuit or by a separate color temperature detector.

Abstract: A solid-state imaging apparatus has an optical iris and a CCD imaging device which responds to light received from an object for producing a picture signal component and a reference black level signal component. A limiter limits the amplitude of the black level component to less than a predetermined value and the amplitude of the reference black level signal component is higher when the CCD imaging device is receiving such a quantity of light that the electric charges generated by photo-charge conversion in the light-sensitive elements in the CCD imaging device may not overflow from the light-sensitive elements. The limited amplitude is lower than the amplitude of the reference black signal component when the electric charges generated by photo-charge conversion in the light-sensitive elements overflow from the light-sensitive elements.

Abstract: Picture elements or light-sensitive elements of a solid-state area image sensor have associated color filter elements with three spectral sensitivity characteristics. The human eye requires a first of these colors to have a spectral sensitivity characteristic for producing a high level of visual resolution such as, for example, a green light of a luminance characteristic. The human eye does not require the second and third colors to have such a high resolution of a spectral sensitivity characteristic, such as, for example, a red or blue light, respectively. The green light-sensitive picture elements are arrayed at alternate picture element positions in every horizontal row and at alternate scanning line positions in every vertical column, in order to form a checkerboard pattern. The remaining picture elements are arrayed so that the interspaces between the green light-sensitive picture elements are alternately occupied in the successive scanning lines by the red and blue light sensitive picture elements.

Abstract: A solid state, color image pickup apparatus separates incident light into three light beams, which diverge in three directions, to form three separate images. Two solid state image pickup devices correspond to a first and a second of the three images formed by the separated light beams. The two object images are a luminance light or a green light image, each having a first spectro-characteristic requiring a high visible resolution. The two solid state image pickup devices receiving the first and second images are displaced away from each other, by a distance in a row direction corresponding to 1/2 of the distance between adjacent picture elements, as viewed in the row direction. A color filter is located at the position of a third object image. The color filter includes cyclically recurring optical filters having a second spectro-characteristic (a blue light characteristic). Neither of these characteristics requires a high visible resolution.

Abstract: An iris controls the amount of light transmitted through television camera lens to an integrated semiconductor matrix of light responsive elements. A characteristic of the matrix is that photo-charges may overflow the light responsive elements if the light falling on the matrix becomes too bright. The normal iris control responds to a loss of picture contrast caused by the overflow of charges and attempts to increase contrast by increasing the amount of light passing through the lens. The invention compares the output from the light responsive elements with a reference signal representing black areas in the picture. When the comparison exceeds a given difference, a special iris control overrides the normal iris control in order to reduce the amount of light passing through the lens. The reference signal may be taken from one or more of the light responsive elements which are shielded from light passing through the lens.
