Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Embodiment one
Referring to Fig. 2, the method for test terminal provided by the invention screen display specifically may further comprise the steps:
Step 101: terminal is preserved after inside converts the screen display result to data, and in fact the data of preservation are exactly result's map in internal memory in some way of screen display;
With the monochrome screen is example, each picture element on the screen is represented with 1 bit, " 1 " expression is black, " 0 " expression is white, the bit of all picture elements on the screen (as from top to bottom, from left to right) is arranged in together, can obtains an array according to a definite sequence, a virtual screen can be thought by Here it is on-screen data district;
In order further to raise the efficiency, usually terminal can be preserved after inside converts this result to data synchronously in the screen display result, certainly in actual applications might be asynchronous, but can not influence the effect of test, because can be controlled at normally carrying out that terminal carries out that the operation rhythm of analogue-key guarantees to test by control appliance, for example suppose that current screen is finished and spent a period of time after the demonstration and just finish the preservation of on-screen data, current screen display result comparison finish after carry out the analogue-key action of terminal by control appliance control this moment, current comparison operation so just can not occur and also not finish the situation that the result of screen display has changed;
Step 102: control appliance sends to terminal and obtains the order that needs data in the comparison zone in the screen, require terminal to extract on-screen data district domestic demand and compare the data in zone and be transferred to control appliance, can specify the regional number (one or more) and this regional scope that need transmission in the order;
This order uses the form of function to realize usually, and can different parameters be set according to the shape difference in concrete zone, and the zone that obtains with need is that a plurality of rectangular areas are that example is described as follows:
GetDispMem(Count，(X1，Y1)，(X2，Y2)，(X3，Y3)，(X4，Y4)，...)
Wherein Count representative need be obtained the quantity of rectangular area, (X1, Y1), (X2 Y2) represents the top left corner apex coordinate and the lower right corner apex coordinate of first rectangular area; (X3, Y3), (X4 Y4) represents the top left corner apex coordinate and the lower right corner apex coordinate of second rectangular area, by that analogy, describe the apex coordinate of Count rectangular area altogether, above-mentioned two apex coordinates also can be lower left corner apex coordinate and upper right corner apex coordinate;
Mentioned order is fairly simple, various areas with irregular may occur in actual applications, just need carry out certain improvement to mentioned order, as increases the summit number in zone or the like, to realize the comparison of irregular area display result;
Step 103: after terminal receives the transmission command that control appliance sends, according to the number in the zone of the need comparison of appointment in the order and scope need be compared the zone from the extracting data in the on-screen data district that terminal is preserved data;
The mode of extracting has a variety of, mask mode more commonly, promptly at first generate a mask image for the zone that needs comparison, each the regional profile outline that has comprised the comparison of current needs in the mask image carries out the mask operation with the data of the data in on-screen data district and the mask image of generation according to the rule of setting then and obtains the data that need comparison regional;

It is exactly common a kind of as the step-by-step AND-operation that the rule of setting has multiple, promptly the array in mask and on-screen data district is carried out AND-operation by turn, the result who obtains is exactly the data that need in the comparison zone, the mask operation just is equivalent to a sieve, play the effect of filtration, promptly the data extract in the zone of needs comparison is come out, in the practical application except regional mask and on-screen data are carried out the step-by-step AND-operation, the mode of operation that can also define other realizes the extraction of data, for example, for color/graphics, each pixel can not be simply with a number but show with a data structural table, at this moment just needing a kind of algorithm, handle for being in the pixel data that needs outside the comparison zone, is a kind of color such as white of agreement with color conversion;
Step 104: the data in the need comparison zone that terminal will extract are handled, as data are organized as the input of certain hash algorithm (as MD5) as an array or character string, obtain the Hash coding of these data and be transferred to control appliance after as calculated;
The step of above-mentioned processing is except calculating with hash algorithm, can also use other method to handle, as adopt CRC (Cyclic Redundancy Check, cyclic redundancy check (CRC)) method that data are handled, perhaps adopt the method for compression that data are handled;
Step 105: after control appliance receives the Hash coding that terminal sends, the Hash with the correct display result in conversion method identical with step 101 and the need comparison zone that identical hash algorithm obtains with step 104 that prestores in this Hash coding and the control appliance encoded compare;
Certainly also can not carry out Hash calculation in the step 104 and directly give control appliance the transfer of data that extracts, correspondingly the data of the correct display result in the need comparison zone that obtains of the conversion method with identical with step 101 that prestores in the data that control appliance is sent terminal in the step 105 and the control appliance are compared, but the volume of transmitted data between terminal and the control appliance is bigger in this case, and correspondingly testing efficiency is lower; After can handling data usually, volume of transmitted data between terminal and the control appliance is transferred to control appliance in order to reduce again in actual applications.
