Camera module array for obtaining compound images
An exemplary camera module array includes lens modules, a first holder, image sensors, a second holder, an optical element, and an image processor. The lens modules are threadedly coupled to the first holder. The image sensors are in optical alignment with the lens modules in one-to-one relation. The image sensors are received in the second holder. The optical element is sandwiched between the first holder and the second holder. The image processor is electrically connected with the image sensors. The image processor is configured for processing image signals from the image sensors and thereby obtaining a compound image.
