Patent ID: 8194137

Claim:
An image frame transmission method, performed by a network transmission system comprising an image sensor and an image processor, said method comprising steps of: said image sensor outputting a first image data segment of an image frame captured by said image sensor to said image processor in response to a first state of a control signal issued by said image processor; said image processor switching said control signal from said first state to a second state to suspend the output of a second image data segment of said image frame, which is previously captured by said image sensor following said first image data segment, from said image sensor to said image processor if said image processor has not completed processing said first image data segment before the output of said second image data segment from said image sensor, and otherwise remaining said control signal in said first state to have said second image data segment outputted from said image sensor to said image processor immediately following said first image data segment without suspension; and said image sensor outputting said second image data segment to said image processor in response to the transition of said control signal from said second state to said first state; wherein a processing period of said image sensor for said image frame is pre-defined with an exposure period for capturing a plurality of image data segments including said first and second image data segments of said image frame, an image data outputting period for continuously outputting said plurality of image data segments of said image frame, and an idle period for waiting to process a next image frame in sequence; and said plurality of image data segments share said idle period to elongate an image data processing period in which said image frame is completely outputted to said image processor with necessary suspension, to beyond said image data outputting period.
