Abstract
Electronic devices may include camera modules. A camera module may be formed from an array of lenses and corresponding image sensors. The array of image sensors may include three color image sensors for color imaging and a fourth image sensor positioned to improve image depth mapping. Providing a camera module with a fourth image sensor may increase the baseline distance between the two most distant image sensors, allowing parallax and depth information to be determined for objects a greater distance from the camera than in a conventional electronic device. The fourth image sensor may be a second green image sensor positioned at a maximal distance from the green color image sensor used for color imaging. The fourth image sensor may also be a clear image sensor, allowing capture of improved image depth information and enhanced image resolution and low-light performance.
