Abstract: A solid state image pick-up apparatus including an objective lens for forming an image of an object, and a color separation optical system for dividing said image of the object into four color images, e.g. first and second green images, a red image and a blue image, one of said four color images being right and left reversed, first to fourth solid state image sensors for receiving said four color images respectively to derive first and second green color signals, a red color signal and a blue color signal. Light receiving elements of said first solid state image sensor are shifted with respect to those of the second solid state image sensor by a half of a pitch at which these light receiving elements are arranged in a horizontal scanning direction to perform a so-called offset-site pick-up. The first and second green image signals are mixed with each other at an ideal ratio of 1:1 to derive a green color signal.

Abstract: A solid state image pickup apparatus includes a solid state image pickup device for receiving an optical image of an object and generating an electrical image signal representing the optical image of the object in synchronism with a driving pulse from a driving circuit. A sampling circuit generates a sampled image signal by sampling the electrical image signal read out of the solid state image pickup device with a first sampling pulse from a first pulse circuit synchronized with the driving pulse. An analog-to-digital convertor converts the sampled image signal to a digital image signal with a second sampling pulse from a second pulse circuit. A test signal generator generates a test signal which is synchronized with the driving pulse and alternately changes in level between consecutive pixels. A controller controls the phase of the first sampling pulse and the phase of the second sampling pulse relative to each other by processing the test signal.

Abstract: A video camera having a plurality of solid-state image sensors in an imaging part uses two kinds of vertical drive signals different in the number of vertical transfer operations, to produce a time lag equal to one horizontal period between the output signals of the solid-state image sensors without changing the optical positional relation between the solid-state image sensors, thereby delaying the red and blue signals with respect to the green signal by one horizontal period based on the application of the two kinds of vertical drive signals.

Abstract: A filter member which can alternatively arrange a proper one of a plurality of kinds of color temperature converting filters onto an optical axis of an image pickup device is provided and the driver of the filter member is controlled by using a plurality of color signals which are generated from the image pickup device, so that a proper color temperature converting filter can always be used. An adjusting mechanism for adjusting relative gains of a plurality of color signals which are generated from the image pickup device is further provided. By also adjusting the adjusting mechanism by using a plurality of color signals which are generated from the image pickup device, an automatic white balance control in a wide color temperature range can be accomplished.

Abstract: Apparatus and a method are described for modifying the magnification and registration factors of an image using digital signal processing and interpolation. The apparatus is used in a camera system which samples an image to generate sampled data signals. The sampled data signals are first interpolated across the either the rows or columns of the image and then across the columns or rows of the image to change the magnification and registration factors of the images represented by each of the sampled data signals to some common desired magnification and registration factors. The system electronically corrects for chromatic aberration and geometric distortion in the image caused by the lens system and skew among the images caused by misalignment of the respective color image sensors.

Abstract: An image pick-up device with an electronic image sensor (IS.sub.1 IS.sub.2) is described, which includes a matrix of sensor elements (SE) and a low-pass filter for suppressing image frequencies exceeding the sampling frequency of the sensor. The low-pass filter has a first, composite filter function (F.sub.com) consisting of a variable component and a constant component and the device has a second filter function (F.sub.c) in conformity with the constant component which is optically or electronically subtracted from the first filter function.

Abstract: A plurality of CCD image pickup devices are provided. When the multiplex exposure is executed, the exposure timings of the plurality of image pickup devices are set to different timings. The output signals of the plurality of image pickup devices of different timings are synchronized and synthesized, thereby forming a multiplexed signal.

Abstract: An automatic white balance regulating device is provided with at least two of a color temperature sensor system, camera color signal processing system and a manual operating system which are selected by a system selector in accordance with a state of shooting circumstance. Thus, a white balance control signal of a system appropriate to the shooting situation is selected so that a white balance regulation can be appropriately performed in accordance with the shooting situation.

Abstract: An imaging system includes a solid-state interline-transfer charge-coupled device (IT-CCD) image sensor having a matrix of rows and columns of photosensitive cells for photoelectrically producing electrical charge carriers in response to an incident light introduced thereonto. Vertical charge-transfer sections are arranged adjacent to the columns of cells, for receiving charge carriers therefrom, and for transferring these carriers toward its outputs, which are coupled with a horizontal charge-transfer section. A charge integration amount control unit is associated with the CCD image sensor such that the controller is coupled to the cell matrix and the vertical transfer sections, for controlling movement of charge carriers from the cell columns to the vertical transfer sections in such a manner that odd-numbered cell rows and even-numbered cell rows are different from each other in the effective amount of charge carriers to be read to the vertical transfer sections as effective signal charge packets.

Abstract: A high quality non-interlaced television signal is generated without using a large size circuit. Interlaced television signals are obtained from four image pickup devices. A luminance or green signal in the interlaced television signals consists of two interlaced channels. These two channel luminance or green signals are simply combined to produce the non-interlaced signal without modifying the driving frequency of the image pickup devices.
