Abstract: 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.
