Core of the present invention is, by taking module with portable terminal to be detected under content imaging shown on the screen, portable terminal to be detected shown content on screen can be to be stored in advance in this portable terminal, also can be to use the captured specific image of self camera by portable terminal to be detected.By main control module the template data of preserving in captured content and the template data module is compared again, and judge according to comparative result whether this portable terminal is qualified.Whole detection has improved detection efficiency fully by computer automatic execution, simultaneously, because object relatively is two groups of data in fact, makes whole comparison procedure more objective and accurate, and therefore, testing result can not influence by detected personnel's subjective factor.
The detection system structure of portable terminal of the present invention as shown in Figure 1.In native system, comprise three modules: taking module, template data module and main control module.
Wherein, taking module is used to take the image that shows on the display screen of detected portable terminal; The template data module is used to preserve template data, just as the data to be compared of template, as data such as size, angularity, colourities; Main control module is used for comparison from the shooting results of described taking module with from the template data of described template data module, such as, data such as the size in data such as the size in the shooting results, angularity, colourity and the template, angularity, colourity are compared, if both differences are in presetting thresholding then the qualified signal of the detected portable terminal of output expression, otherwise the underproof signal of output this portable terminal of expression.
More than the detection system structure of portable terminal is illustrated, below the dynamic duty process of this system is simply introduced.
Taking module in the system gets off by the image taking that shows on the display screen of external camera with portable terminal to be detected in the detection system, and shooting results is sent to main control module in the system.Main control module with this shooting results with compare from the template data of template data module in the system, if both differences are in presetting thresholding then the qualified signal of the output detected portable terminal of expression, otherwise the underproof signal of output this portable terminal of expression.
The detection method of the portable terminal that the present invention first implements as shown in Figure 2.
In step 210, detected portable terminal display image on display screen.Specifically, detected portable terminal is when the ad-hoc location that is in when detecting, such as the display screen of detected portable terminal is when being right against the camera of detection system, this portable terminal is display image on its display screen, shown image is to be stored in the specific image of this portable terminal inside in advance, such as can embody the various stripeds of angularity, the various color lumps of embodiment colourity etc.
Then, enter step 220, take image shown on the display screen of detected portable terminal from the outside.Specifically, the taking module of detection system is taken by shown specific image on the display screen of external camera to detected portable terminal on the detection system, and shooting results is sent to main control module in the system.
Then, enter step 230, shooting results and template data are compared by main control module.Specifically, stored data to be compared in the template data module in system,, and this template data sent to main control module in the system as data such as size, angularity, colourities as template.The shooting results that main control module will obtain in step 220 and this template data compare.Because what taking module was taken is the specific image that is stored in the detected portable terminal, and, by taking also with the indirect digitlization of the output of this portable terminal, therefore, the shooting results that obtains can carry out various comparisons with template data, and content relatively can comprise the combination in any of size of images, angularity and colourity or one of them.And, whether cross-color, distortion, phenomenon such as fuzzy can be arranged according to the image that the concrete data difference in the comparative result is judged shooting, that is to say, main control module can to shooting results be stored in template data in the template data module and compare after, according to the concrete data difference in the comparative result whether in allowed band, whether the image of judging shooting is qualified, and just whether the shown image of the display screen of detected portable terminal is qualified.Such as default thresholding in main control module is if the image of taking and template horizontal stroke, vertical number of pixels are all identical, then the value of respective pixel is subtracted each other, and the result after subtracting each other got variance, if this variance has surpassed predetermined thresholding, judge that then the captured image of taking module is defective.Certainly, can more multinomial respectively content relatively the time, can adopt different comparison algorithms to each content, finally obtain quantitative comparative result, therefore, can know not only whether the shown image of the display screen of detected portable terminal is qualified, under underproof situation, can also further know the shown underproof concrete place of image of display screen of detected portable terminal, for example, be to have cross-color, or anamorphose, phenomenon such as still image blurring.

In the present embodiment, take by display image detected portable terminal, with the indirect digitlization of the output of portable terminal, by main control module this shooting results and the template data that is stored in the template data module are compared again, can more multinomial respectively content relatively the time, can adopt different comparison algorithms to each content, finally obtain quantitative comparative result, this makes that process relatively is more objective and accurate, and judges according to comparative result whether this detected portable terminal quality is qualified.Whole testing process can be automatically performed by detection system fully, has improved detection efficiency, and in comparison procedure, relatively come down to two groups of data, therefore, compare with manual detection, testing result can be not different along with testing staff's difference, improved accuracy of detection greatly.
What second execution mode of the present invention was different with first execution mode is, in the present embodiment, what detected portable terminal showed on its display screen is not the specific image that is stored in this portable terminal, but the specific image that this portable terminal is taken by the camera that carries.Therefore, detected portable terminal must comprise camera, is used to take predefined image, and shooting results is presented on the display screen of self, as shown in Figure 3.
The detection side of the portable terminal of second execution mode of the present invention as shown in Figure 4.
In step 410, the self-contained camera of detected used for mobile terminal is taken predefined external image, and shooting results is presented on the display screen of self.Specifically, detected portable terminal self has camera, when the portable terminal that camera is installed during at the ad-hoc location that is in when detecting, such as the camera of detected portable terminal is right against predefined external image, when the display screen of detected portable terminal is right against the camera of detection system, main control module in the detection system is controlled this portable terminal by the Data Control mouth of portable terminal and is taken predefined external image, as embodying the various stripeds of angularity, the specific image of various color lumps of embodiment colourity and so on is taken, and shows on display screen.
Then, enter step 420, take image shown on the display screen of detected portable terminal from the outside.This step is identical with step 220, does not repeat them here.
Then, enter step 430, shooting results and template data are compared by main control module.This step is identical with step 230, does not repeat them here.
Then, enter step 440, whether qualified main control module output comparative result just export detected portable terminal signal.This step is identical with step 240, does not repeat them here.
This shows, the present embodiment and first execution mode are basic identical, difference only is, detected portable terminal shown content in its display screen is stored in the specific image in this portable terminal in advance in first execution mode, and in the present embodiment, detected portable terminal shown content in its display screen is the predefined external image that the self-contained camera of this used for mobile terminal is taken.Therefore, in the present embodiment, not only can reach the raising identical detection efficiency and accuracy of detection to portable terminal with first execution mode, can also finish shooting once and show the detection of two kinds of functions, this is to show qualified image because in general have only shooting and show that two kinds of all qualified ability of function are final.
