MFPs that handle digital image data, which is a part of digital data, have been provided with and integrated with new functions and have become multifunctional, and further provision and integration of new function I / Fs are desired.

  However, while the functions of the MFP are increasing in functionality, the size of the MFP tends to be reduced, and restrictions on the board layout are becoming strict in the image processing apparatus. In addition, with the increase in functionality, a plurality of debug I / Fs are required, and restrictions on board layout, cost increase, and debug efficiency required for mounting the debug function are also problematic.

Therefore, for example, Patent Document 1 aims to provide an image processing apparatus capable of realizing a reduction in cost required for implementation of a debug function and simplification of a board layout. An image processing apparatus for outputting an image by a plurality of image processing means for performing different image processing on the input image data, and transmitting the image data between the plurality of image processing means and the image output means. An image bus, a single image debugging interface unit that is arranged on the image bus and performs at least one of input and output of the image data, and which of the plurality of image processing units is used by the image data A designation means for accepting designation from the image debug interface means after image processing; Control means for performing image data processing by the designated means received by the control means for controlling the output of the processed image data from the image debug interface means without performing subsequent processing after the processing by the designated means; There has been proposed an image processing apparatus including the above.

In this processing procedure, instead of the processing in step S601 in the sixth embodiment, the normal mode or the debug mode is selected from the operation unit 9, and the image reading unit or the image processing unit that needs to write-protect the memory unit storage area. Output image data (processing result) is selected (step S701). The processing after step S702 is the same as the processing after step S602 in the sixth embodiment, and the last two digits representing the step. Since the numbers indicate the same process, the duplicate description is omitted.

  In this embodiment, the image data output from the image reading unit 1 is identified by the image bus control unit 7 and then the write protection to the memory unit storage area 4b selected by the operation unit 9 is OFF. Is stored in both the temporary storage area 4a and the storage area 4b of the memory unit 4, and is stored only in the temporary storage area 4a of the memory unit 4 when ON.

  FIG. 17 is a diagram illustrating an image processing flow P9 when the write protection of the storage area of the memory unit of the output image data of the image reading unit 1 and the first processing unit 5a in the present embodiment is turned on.

In the flowchart of FIG.
Step S707 → Step S708 → Step S709 → Step S711 → Step S712 → Step S714 → Step S715
It is.

  According to the present embodiment, when a malfunction such as an abnormal image occurs, the output image data (processing result) from the image reading unit 1 and the image processing unit 5 accumulated in the plurality of accumulation areas 4a and 4b necessary for the analysis. Therefore, it is possible to prevent unintentional overwriting of only image data (processing result) that needs to be protected.

  The eighth embodiment is an example in which the write protection can be set from the connection detection of the image debug I / F with respect to the sixth embodiment.

  In the eighth embodiment, the write protection is set to ON from the connection detection when the debug device or the like is connected to the image debug I / F 8. FIG. 16 is a flowchart showing the processing procedure of the seventh embodiment, but the processing procedure in the eighth embodiment is also the same as the flowchart of FIG. 16 except that the write protection is turned on from the connection detection. That is, the image data output from the image reading unit 1 is subjected to identification of additional information by the image bus control unit 7 (step S703), and then the write protection ON / OFF from the operation unit 9 to the memory unit storage area in step S704 is performed. Even if it is forgotten to turn on the write protect with the OFF setting, the write protect is turned on from the connection detection when the debug device or the like is connected to the image debug I / F unit 8, and the temporary storage area 4a of the memory unit 4 is turned on. (Step S705). Since the subsequent processing is the same as that of the sixth embodiment, description thereof is omitted.

  According to the present embodiment, even when the protection setting is forgotten when a malfunction such as an abnormal image occurs, the write protection is turned on from the detection of the connection of the debugging device or the like to the image debugging I / F unit 8. In addition, it is possible to prevent unintentional overwriting of output image data (processing results) from the image reading unit 1 and the image processing unit 5 accumulated in the plurality of accumulation areas 4a and 4b necessary for analysis.
