Image frame transmission method
First Claim
1. An image frame transmission method for use in a network transmission system, said network transmission system comprising an image sensor and an image processor, said method comprising steps of:
- 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 after an initial signal has been asserted by said image processor;
delaying the output of a second image data segment of said image frame following said first image data segment to said image processor in response to the transition of said control signal from said first state to a second state; and
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 second state.

Abstract
An image frame transmission method for use in a network transmission system is provided. The network transmission system includes an image sensor and an image processor. Firstly, a first image data segment of an image frame captured by the image sensor is outputted to the image processor in response to a first state of a control signal after an initial signal has been asserted by the image processor. Then, the output of a second image data segment of the image frame following the first image data segment to the image processor is delayed in response to the transition of the control signal from the first state to a second state. Afterward, the second image data segment is outputted to the image processor in response to the transition of the control signal from the second state to the first second state.

13. An image frame transmission method for use in a network transmission system, said network transmission system comprising an image sensor and an image processor, the processing period of said image sensor for an image frame being pre-defined with an exposure period, an image data outputting period and an idle period in sequence, said image frame consisting of a plurality of image data segments is completely outputted to said image processor within an image data processing period, and said method comprising steps of:
-
asserting an initial signal for outputting said image frame after said exposure period;
asserting a control signal which toggles between first and second states according to a certain rule;
outputting said plurality of image data segments to said image processor segment by segment in response to said first state of said control signal;
pausing the output of said plurality of image data segments whenever said control signal toggles from said first state to said second state; and
restoring the output of said plurality of image data segments in response to the transition of said control signal from said second state to said first second state. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
