1. An image signal processing system comprising: front-end processing logic comprising: a first input configured to receive image data from a first image sensor; a second input configured to receive image data from a second image sensor; a front-end pixel processing unit configured to process the image data received from the first and second image sensors on a frame-by-frame basis; and a front-end control unit configured to operate the front-end processing logic in a single sensor mode if only one of the first and second image sensors are active and in a dual sensor mode if both of the first and second image sensors are active; wherein when operating in the single sensor mode, image frames acquired by the active sensor is provided directly to the front-end pixel processing unit for processing by a sensor interface of the active sensor; and wherein when operating in the dual sensor mode, image frames acquired by the first sensor and image frames are acquired by the second sensor are provided to the front-end pixel processing unit in an interleaved manner.
