Abstract: A device performs color balance adjustment on the basis of color temperature information obtained by adding up measured color information outputs sampled from color sensors which obtain measured color information from an object to be photographed.

Abstract: An image pick-up device which uses a charge transfer type solid state image pick-up device, and further is provided with a shutter so as to form a high quality picture signal in such a manner that smear is prevented by prohibiting the incidence of light on the device while the charge is being transferred in the device. Further, the device is driven by a clock signal for still photographing in order to obtain a high quality picture information for one frame. Further, the photographing parameter is automatically changed over or the monitor is changed over between the motion picture photographing mode and the still photographing mode.

Abstract: A color image pickup device suppresses false color signals in order to provide true color reproduction. That is, the device incrementally or continuously reduces false color signals. More particularly, this device includes a color separation filter through which an optical image passes to an image pickup device such as a CCD sensor or the like. A suppression circuit that includes a low pass filter and a high brightness detector detects when the brightness of the optical image exceeds a predetermined level. A color signal forming circuit forms a plurality of color signals from the output of the image pickup device and this plurality of color signals are output by a sequencing circuit in a predetermined cycle. The output level of the sequencing circuit is adjusted in response to the output of the detector by a control circuit, and this output is modulated by a modulator.

Abstract: An image pickup apparatus capable of removing unnecessary charge in the image pickup area during charge storage, which apparatus can perform a clamp processing of a video signal without being affected by such a removal operation of the unnecessary charge.

Abstract: A capacitor coupled circuit includes a power supply switch for switching power supply on; a coupling capacitor provided in a signal line; and a control circuit arranged to cause the capacitor to be charged or to be discharged in a short period of time according to the operation of the power supply switch. The arrangement enables the capacitor coupled circuit to obtain a stabilized constant output voltage in a short period of time after the power supply is switched on.

Abstract: An image sensing apparatus including an image sensor for converting light representing an optical image to an image signal; processing circuits for processing R, G and B component signals of the image signal; a non-feedback clamp circuit for clamping the G component signal to a fixed reference level; two feedback clamp circuits for clamping the R and B component signals to levels determined on the basis of the levels of the processed clamped R and B component signals, respectively; and an automatic exposure controller for controlling the amount of light incident on the image sensor in accordance with the level of the clamped processed G component signal. The apparatus decreases the time it takes for the automatic exposure controller to respond when the apparatus is first turned on.

Abstract: The disclosed image sensing device includes a sensing arrangement for converting an optical image into an electrical signal; an iris for adjusting the quantity of light supplied to the image sensing arrangement; gain control circuits for adjusting amplification gains of monochrome or color difference signals obtained from the image sensing arrangement; a peak detecting arrangement for detecting the peak values of the monochrome or color difference signals; a balance control for controlling the gain control circuits for white balance adjustment according to the signals obtained from the peak detecting arrangement; and an iris control for controlling the iris such that the output of the image sensing arrangement becomes lower when the gain control circuits are under the control of the balance control than when they are under a normal photographic condition.
