摘要： In a solid state imaging device in which two signals on two horizontal scanning lines are read out simultaneously for easy image enhancement, the two signals read from the two horizontal scanning lines are subtracted from each other while they are added together, and the difference signal is added to the sum signal so as to produce a video signal subject to the image enhancement. As a solid state image sensor, a MOS type image sensor as well as a CCD, CID or CC type image sensor may be used.

摘要： The present invention relates to a color imaging device which suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary part in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizontal direction is little and the false signal appears in a boundary part in the horizontal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the vertical direction.As a result, the moire phenomenon attributed to the false color signals can be conspicuously reduced.While embodiments of the present invention refer to color imaging devices which employ MOS type solid-state imaging devices, the invention is also applicable to an imaging device which employs CCDs and a color image pickup tube which separates colors by means of a mosaic color filter.

摘要： A signal for a first scanning line including a picture element whose signal does not exist and a signal for a second scanning line adjacent to the first scanning line in the same field are obtained in the same period. Then, a coefficient representing the ratio of the level of the signal for the first scanning line to the level of the signal for the second scanning line is calculated. Multiplying by the coefficient the level of the signal for the second scanning line to thereby provide an interpolation signal.

摘要： An image pickup apparatus for a television and a depth-of-field control apparatus used in the same. Image signals corresponding to a plurality of picture images different in focal point or length position are obtained by a mechanism for changing a focal point or length position to produce a new image signal by composing these image signals through a composition circuit, and motion information of an object is obtained by a circuit for detecting a moving portion in the object to control the image composition by the motion information. The focal point or length position is moved in synchronism with an integer multiple of a vertical scanning period of the television. The image signals corresponding to the plurality of picture images different in focal point or length position are obtained within one vertical scanning period determined by the system of the television. The amount of movement of the focal point or length position is controlled in conjunction with a value of a lens aperture of the camera lens. The image composition is controlled by a composition control circuit made up of a circuit for detecting individual powers of image signals corresponding to a plurality of different picture images, a circuit for comparing the detected powers with each other, and a circuit for detecting the position of an edge included in one of the image signals, wherein a control signal for the image composition produced by the power comparison circuit is compensated by the edge position information obtained by the edge detection circuit.
