Abstract
Image data from an image sensor is read out, wherein when reading out, processor(s) is/are configured to employ subsampling. The image data is processed, using neural network(s), to generate an image.
Claims9
An imaging system comprising:
- an image sensor chip comprising:
- a colour filter array comprising a plurality of smallest repeating units, wherein a given smallest repeating unit comprises colour filters of at least three different colours;
- and
- a plurality of photo-sensitive cells arranged on a photo-sensitive surface of the image sensor chip, wherein the photo-sensitive surface has gaps between consecutive rows or columns of smallest repeating units, a size of a given gap lies in a range of 0.25 times to 2 times a width of the given smallest repeating unit;
- and
- at least one processor configured to:
- read out image data from the image sensor chip;
- and
- process the image data, using at least one neural network, to generate an image.

An imaging system comprising:
- an image sensor chip comprising:
- a plurality of neuromorphic sensors arranged in at least 50 percent of rows and/or columns of a photo-sensitive surface of the image sensor chip;
- a plurality of photo-sensitive cells arranged in a remaining portion of the photo-sensitive surface;
- and
- a colour filter array arranged on an optical path of the plurality of photo-sensitive cells, the colour filter array comprising colour filters of at least three different colours;
