Abstract
A multi-image sensor system includes data, clock, and control buses, an application processor connected to the data bus and the clock bus, and image sensors connected in a daisy chain using the control bus. A first one of the image sensors configured as a master outputs image data to the data bus, outputs a first clock signal to the clock bus, and sends a control signal to a second one of the image sensors in the daisy chain through the control bus. The control signal has a first logic state when output of the first image data starts and a second other logic state when output of the first image data ends. The second image sensor connects itself to the data bus and the master disconnects itself from the data bus according to a state of the first control signal.
