Abstract:
1. An image-sensing apparatus for compensating a video signal of a plurality of channels comprising: an image-sensing device having a plurality of divided pixel areas to output a plurality of channels of video signal corresponding to each area and a vertical pilot signal adder provided for each of the plurality of divided pixel areas, the vertical pilot signal adder further comprising an adding means for adding an electric charge of a pilot signal to an output signal of each of the plurality of pixel areas for more than once at different electric potentials; a detection means for detecting the pilot signal from the output of each channel of the image-sensing device; and a control means for controlling an output signal level of the video signal for each channel, wherein the control means controls the output signal level by calculating a difference of the pilot signals from a predetermined value for each channel, and equalizing the difference of the pilot signals in each channel.
