Abstract: An imaging system includes an encoding apparatus that performs a multiple sampling process on charge signals in a plurality of wavelength bands and encodes image information and a decoding apparatus that decodes the image information. In the multiple sampling process, the charge signals of pixels in a pixel group having a predetermined arrangement pattern are analog-summed and the sum is converted into a new digital signal. The encoding apparatus performs the multiple sampling process on charge signals in at least two of the wavelength bands and outputs a digital image signal in each of the wavelength band. The at least two pixel groups have different arrangement patterns, and combinations of the arrangement patterns for all the wavelength bands differ from one another. The decoding apparatus generates a reconstructed image from the digital image signals in the wavelength bands using multiple sampling information and outputs the image.
