Image sensor and camera assembly

A camera assembly comprising:

• a lens assembly;
• and
• an image sensor comprising:
• a substrate comprising a curved photosensitive surface facing the lens assembly and arranged at a focus of ambient light transmitted from the lens assembly;
• and
• a plurality of pixels on the curved photosensitive surface and arranged in an array comprising a plurality of rows and a plurality of columns, each of the plurality of row extending along a first direction X and each of the plurality of columns extending along a second direction Y perpendicular to the first direction X, and a first spacing between geometric centers of each two adjacent pixels of the plurality of pixels gradually decreasing from a center of the substrate to an edge of the substrate;
• wherein the lens assembly is on a side of the image sensor having the photosensitive surface and is configured to focus the ambient light onto the photosensitive surface.
