Background technology
Along with the high speed development of sensor technology and computer technology, video image processing system has been widely used in the various aspects of productive life.Video image processing system always produces time-delay to video signal flow when carrying out Video processing, the use occasion that inappropriate time-delay is strict to real-time, for example video monitoring, aim target, automobile video frequency pilot result of use can produce a very large impact, even bring danger and disaster.Therefore image processing system is carried out accurately and easily time-delay detection, have great significance.
Patent publication No. be CN 102158728 A a patent announcement a kind of video image processing system delay detection method, may further comprise the steps: step 1, utilize the required test pattern of PC editor, test pattern is sent into the test video generator, and the test video generator is present among the flash test pattern standby; Step 2, select test pattern by host computer according to the system under test (SUT) video standard in when test, and concrete sequence form and the video format of test video; Step 3, test video is sent into system under test (SUT); Step 4, test video and system under test (SUT) output video that step 2 is produced are sent into oscilloscope or logic analyzer, and the tester reads the input and output time difference, is the system delay amount.
But there is this bigger deficiency in this invention in practicality, need rely on plurality of devices such as PC, oscilloscope during detection, therefore be not easy to carry, and also complicated operation, the testing time is longer, and in addition, artificial sentence read result is easy to produce mistake and surveys.
Summary of the invention

Description of drawings
Fig. 1 is theory structure block diagram of the present invention.
Embodiment
The embodiment that the present invention is cited; just be used for helping to understand the present invention; should not be construed as the restriction to protection range of the present invention; for those skilled in the art; under the prerequisite that does not break away from inventive concept; can also improve and modify the present invention, these improvement and modification also fall in the scope of claim protection of the present invention.
As shown in Figure 1, the present invention includes:
Video analog signal generation module, for generation of test signal, in order to improve test accuracy, the P-P that the test signal that produces preferably is in the peak value state is the analog video letter of 1.0V.
With the controller that video analog signal generation module is electrically connected, make test signal produce step.As embodiments of the invention, described controller is switch, by the break-make of switch control test signal, thereby makes test signal produce very significantly step.Test signal is through behind the controller, and two signal output interfaces by on the controller are divided into two-way and transmit.An output interface is used for to test target output test signal, and another output interface is used for to input signal acquisition module output test signal.
The input signal acquisition module, the input signal of collecting test target also is converted to digital signal.Described input signal acquisition module has analog input interface, is connected with a signal output interface of controller.
The output signal acquisition module, the output signal of collecting test target also is converted to digital signal.Described output signal acquisition module has analog input interface, can be connected with the signal output interface of test target.
Signal processing module, this module have two digital signal input interfaces, are electrically connected with input signal acquisition module and output signal acquisition module respectively.Described signal processing module can catch the step point of test target input signal and test target output signal, and calculates both time differences;
The display module that is electrically connected with signal processing module comprises LCD display and single-chip microcomputer, is used for the time difference of storage and demonstration test target input signal step point and test target output signal step point;
Power supply to above-mentioned module and parts power supply.
Operation principle of the present invention is:
Video analog signal generation module produces analog signal, and the break-make of control switch control test signal produces logical and disconnected test signal.Test signal is divided two-way output, and a drive test trial signal is exported to test target, and the output interface of process test target is sent to the output signal harvester and is converted to digital signal.Another drive test trial signal is exported to the input signal acquisition module, and is converted to digital signal.
Whether the signal that signal processing module detection input signal acquisition module sends exists the signal step, in case detect the signal step then start timing, simultaneously, whether the signal that signal processing module also detects the transmission of output signal harvester exists the signal step, also starts timing in case detect the signal step.
After signal processing module detects two step signals, calculate the time difference of two step signals, this time difference is the delay data of system under test (SUT), simultaneously delay data is shown by display and stores.By the repeatedly break-make of controller, many group delay datas can be stored and show to display, and the arithmetic mean that can get this multi-group data is the final delay data of system under test (SUT).
