摘要： An image-sensing apparatus for compensating video signal of a plurality of channels, adds an electric charge of a pilot signal on a signal vertically transferred in an image-sensing device 11. A pixel area of the image-sensing device 11 is divided into a plurality of pixel areas to obtain an output signal of a plurality of channels. The pilot signal is add to an output signal of each pixel area corresponding to each channel for twice a field period, and for different electric potential. The control circuit 15 obtains a difference between the two pilot signals in one filed period, and controls the gain compensation 17 to make the pilot signal level in each channel equal. Additionally, the pilot signal is not used for compensation but the previous signal is used when a smear element is detected from the output signal of each channel.

摘要： A video camera which is provided with an inter-line type CCD and also which enjoys a function as a digital still camera. The video camera includes an irising mechanism for adjusting a quantity of light incident upon the CCD, an iris driving circuit for driving the irising mechanism, and a camera microcomputer for controlling operations of adjusting an incident-light quantity by the irising mechanism by controlling the iris driving circuit. The camera microcomputer controls the iris driving circuit to drive the irising mechanism, whereby the incident light upon the CCD is blocked to perform only a read-out operation while data of all the pixels is read out from the CCD.

摘要： An imaging apparatus has a solid-state image sensing device having an imaging area divided into left and right sub-imaging areas, a first optical-black (OB) area and a second OB area being provided at both edges of the imaging area in the horizontal direction. First video signals are extracted from monitoring areas in the sub-imaging areas close to the border between the sub-imaging areas. Optical-black clamping is applied to second video signals output from the sub-imaging areas by subtracting a first OB signal indicating an OB level in the first OB area from the second video signal output from one of the sub-imaging area and subtracting a second OB signal indicating an OB level in the second OB area from the second video signal output from the other of the sub-imaging areas. Detected first in the optical-black clamping is a level difference between the extracted first video signals. Calculated next is an adjusting value per row of pixels, that provides the smallest level difference per row of pixels in the imaging area based on the detected level difference. The first OB signal is subtracted from one of the second video signals and the second OB signal is subtracted from the other second video signal, thus outputting an optical-black-clamped video signal. Video-signal levels are adjusted by multiplying the optical-black-clamped video signal by the adjusting value.
