Camera system, controller thereof, automobile, and deserializer circuit

A controller structured to control a plurality of camera modules, each of which is structured to capture image in response to an assertion of a corresponding frame synchronization signal, to transmit frame data including the captured image and to transmit a transmission synchronization signal which is asserted in synchronization with the transmission of the frame data, and to process video images captured by the plurality of camera modules, wherein the controller comprises:

• a plurality of receivers each structured to receive the frame data and a transmission synchronization signal that is synchronized with the frame data from a corresponding one of the plurality of camera modules, wherein the transmission synchronization signal is a timing signal;
• an image processing unit structured to process a plurality of items of frame data received by the plurality of receivers;
• a synchronization signal generating unit structured to generate a plurality of frame synchronization signals that correspond to the plurality of camera modules, wherein the plurality of frame synchronization signals are timing signals, and the controller asserts each frame synchronization signal at an image capture timing at which the corresponding one of the plurality of camera modules should capture the image;
• a plurality of delay measurement units each structured to acquire a time difference between an assertion of a corresponding one of the plurality of frame synchronization signals and an assertion of a corresponding transmission synchronization signal;
• and
• a plurality of transmitters structured to transmit the plurality of frame synchronization signals to the plurality of camera modules respectively,
• and wherein the plurality of frame synchronization signals have a timing relation that is adjustable based on time differences measured by the plurality of delay measurement units.
