Abstract
Electronic devices may include camera modules. A camera module may include an anamorphic lens and an image sensor having an array of asymmetrical image pixels. The array may be a square array arranged in pixel columns and pixel rows. The square image pixel array may include more pixel columns than pixel rows and may be located completely within the image circle of the anamorphic lens. The asymmetrical image pixels may each have a width that is smaller the height of that image pixel. The asymmetrical image pixels may be rectangular image pixels or diamond-shaped image pixels. The anamorphic lens may project a distorted image onto the array of asymmetrical image pixels. The width of each asymmetrical image pixel may be smaller than the height of that image pixel by an amount that corresponds to the distortion of the image by the anamorphic lens.
