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.

Abstract: An image capturing apparatus includes a first camera that captures a first image, a second camera that captures a second image, a lens cover that includes transparent parts and ridgelines and that covers the first camera and the second camera, and a processing circuit that identifies a pixel located in an area, in which it is necessary to interpolate a pixel value, in the first image, and generates an output image using the first image and interpolation pixel information for interpolating a pixel value of the identified pixel. Each ridgeline between adjacent parts of the lens cover is twisted with respect to a base line extending between a center of a first lens of the first camera and a center of a second lens of the second camera. An upper part of the lens cover opposes a base on which the first camera and the second camera are disposed.
