The operation of the execution program selection device having such a configuration will be explained. FIG. 3 is a flowchart showing the operation of the execution program selection device of the present invention.

In FIGS. 1 to 3, the parameter analysis unit 21 manually receives the user's image processing request 31) and analyzes the processing request based on the parameter analysis table 26 (S2). It is examined whether the processing request matches the command conditions, and if so (S3), the processing name and parameters are given to the execution program selection unit 22 as analysis results (S3).
4). The execution program selection unit 22 selects an optimal execution program based on the analysis result and the contents of the selection control table 27 (S5). The program starting unit 23 gives an instruction to execute the selected execution program to the corresponding program executing unit and starts the program (S6). The first program execution unit 24 or the second program execution unit 51 executes the selected optimal execution program.

If the processing request does not match the command conditions, the process goes to step Sl and waits for the processing request to be input again.

(Margins below this page) Table 1 is a parameter analysis table of the execution program selection device of the present invention. Table 2 is a selection control table of the execution program selection device of the present invention.

An example of operation will be explained in more detail. Parameter control section 2
1, 'anflΔa, Xl+ y L+ E
When an affine transformation processing request such as L X2+ X2+ +' is input, the parameter analysis unit 21
Refer to the parameter analysis table 26 shown in Table 1 and search for the command name afnl'. If it is found, it is checked whether parameters from parameter a to parameter y2 meet the conditions of the command with command name afnl. If the command name is not found, it is determined as an error and the processing request is made again manually. To check the parameters, conditions are set such that parameter 1 is a character type and is within 10 characters, and parameter 2 is a positive integer type and is within 4 digits, so the conditions and input parameters are checked. If all the parameters satisfy the conditions, the parameters are type-converted according to their respective type attributes, and the information is passed to the execution program selection section 22. The execution program selection unit 22 selects an optimal execution program by referring to the selection control table 27 for the passed command name, that is, the process name and its parameters. The optimal execution program is one that can execute the requested processing, but also one that can be executed in the shortest processing time. As shown in the selection control table 27 shown in Table 2, there are three types of execution programs AFNI and AF that execute affine transformation.
N2 and AFN3 are prepared, and conditions such as data type, image size and affine transformation method, processing time, etc. of human image data and output image data are set in this table. The execution program AFNl is
It is assumed that the program runs on the processing unit 20 of the host computer 10, and the execution program AFN2 is a program on the image processing dedicated processor 40 connected to the host computer 10.

If both human image data and output image data are stored in the memory of the processing unit 20 of the host computer 10, the processing time of the execution program AFN1 is determined by the computing power of the processing unit 20, and the processing time of the execution program AFN2 is determined by the processing capacity of the processing unit 20 of the host computer 10. It is determined by the data transfer time between the processing unit 20 of 10 and the image processing dedicated processor 40 and the computing power of the image processing dedicated processor.

The processing time of execution processor AFN1 is t+=r+1m
g) The data transfer time between the processing unit 20 of the host computer 10 and the image processing processor 40 is tz+=f 2
1 (Img) The processing time of the execution program AFN2 in the image processing processor 40 is t2. = r 22 (img).

Here, f (img) is a function determined by the size of image data. The processing time of execution program AFN1 and execution program AFN2 is processing time t1.
It is sufficient to compare the processing time (tz++t22). Although the computing power of an image processing processor is usually several tens to thousands of times greater than that of the processing section 20 of the host computer 10, its effectiveness is reduced if data transfer takes too long. That is, it is determined whether it is better to select execution program AFN1 or execution program AFN2 depending on the size of the image data.

The above explanation is an example of selection based on processing time, but depending on the program, it may not be possible to execute unless certain conditions are satisfied, and the processing algorithm may be different. The execution program selection section 22 of this embodiment checks the selection control table 27 in which various conditions are set according to the contents of the user's request, and determines the most suitable execution program.

Once the program to be executed is determined, the program name and parameters are passed to the program starting unit 23. The program execution unit 24.51 executes an optimal execution program based on the instruction information.

As explained above, the execution program selection unit 2 automatically determines the optimal execution program based on the selection control table 27.
2 can solve the problem that the execution program specified by the user cannot be executed or that even if it can be executed, it takes unnecessary processing time.

Furthermore, when creating a new execution program and incorporating it into this device, if the configuration of the present invention is used, the selection control table 27
Program registration is completed by simply setting the program name and its conditions.

That is, there is an advantage that it is not necessary to relink a new program with an existing program group.

〔Effect of the invention〕

As described above, the present invention has the excellent effect of reducing the burden on the user and efficiently performing processing. Furthermore, when creating and registering a new program, there is an advantage in that it is only necessary to set the program name and conditions in the selection control table.
