ABSTRACT:
A high speed imaging apparatus capable of speeding up the imaging rate, without causing the lowering of the dynamic range of the image data. The imaging apparatus includes a first signal processing unit for dividing each channel of the image information signals outputted from the imaging element into a plurality of signal channels; a plurality of A/D converters, each of which is provided in correspondence to each one of the signal channels of the image information signals and converts the image signals of respective one of the signal channels into digital image signals; and a second signal processing unit for combining the digital image signals obtained by the A/D converters into a single channel of digital image signals representing the image to be taken.
