发明名称 Imaging apparatus and signal processing method for correcting deterioration of the image signal
摘要 An imaging apparatus which enables correction of signal deterioration responsible for transfer deterioration occurred in a horizontal charge transfer path is provided. Provided that positions of “n” transfer packet formed in a horizontal charge transfer path in correspondence to “n” vertical charge transfer paths are expressed as a coordinate “i” (i=1, 2, 3, . . . n), a solid-state imaging device is exposed under exposure conditions, and reference charges generated in photoelectric conversion elements upon the exposure are accumulated in transfer packets located at odd coordinates. The charge accumulation packets accumulating the reference charges and other empty packets are transferred horizontally, whereby a reference signal responsive to the reference charge and an untransferred signal responsive to a charge in the empty packet are output. The thus-output signals are stored in memory. Deterioration of an imaging signal S(i) responsive to the charge accumulated in the transfer packet located at the coordinate “i” in a photographing mode during exposure is compensated for in accordance with the data stored in the memory and the imaging signal S(i).
