Abstract

An image processing system, such as a facsimile system, in which a source transmits information to a receiver. The information includes an identification signal which indicates whether image data or an extended program, such as a diagnostic program, is to follow. If image data follows, the receiver processes the data in a normal manner. If the diagnostic program follows, it is stored in a memory for subsequent execution. Since the program doesn'"'"'t have to be stored in the memory at all times, the memory is used more efficiently. The receiver may request transmission of the diagnostic program in the event of a system failure. The source may transmit a starting time for execution of the diagnostic program.

Claims

1. A facsimile apparatus for receiving and transmitting image information, comprising:

receiving means for receiving image information and program information which is used to control the facsimile apparatus;

determining means for determining whether the information received by said receiving means is the image information or the program information;

controlling means for processing the image information in a case where the received information is determined to be the image information, and

for storing the program information into memory means in a case where the received information is determined to be the program information,

wherein said control means controls the facsimile apparatus according to the program information stored in the memory means,

wherein the program information received by said receiving means includes attribute information which indicates attributes of the program information.

2. The facsimile apparatus according to claim 1, wherein the program information includes an extended program.

3. The facsimile apparatus according to claim 2, wherein the extended program is used for performing a self-diagnostic function.

4. The facsimile apparatus according to claim 1, wherein said determining means determines that the received information is the program information in accordance with detection of information, included in a signal for a facsimile control procedure, which indicates that the program information is to be transmitted.

5. The facsimile apparatus according to claim 1, wherein said controlling means erases the program information stored in the memory means after elapse of a predetermined time period.

6. The facsimile apparatus according to claim 1, further comprising designating means for designating a starting time for the execution of the program information,

wherein said controlling means controls the facsimile apparatus in accordance with the program information received by said receiving means at the starting time designated by said designating means.

7. The facsimile apparatus according to claim 1, further comprising input means for inputting an execution designation by an operator,

wherein said controlling means controls the facsimile apparatus according to the program information received by said receiving means in response to the designation input by said input means.

8. The facsimile apparatus according to claim 1, wherein said controlling means controls the facsimile apparatus in accordance with the program information received by said receiving means when storage of the program information is completed.

9. The facsimile apparatus according to claim 1, wherein said memory means stores the program information in a RAM separately from an already existing program information stored in a ROM.

10. The facsimile apparatus according to claim 9, wherein the RAM is the same as a RAM which stores the image information.

11. A control method of facsimile apparatus for receiving and transmitting image information, comprising the steps of:

receiving image information and program information which is used to control the facsimile apparatus;

determining whether the information received at said receiving step is the image information or the program information;

processing the image information in a case where the received information is determined to be the image information;

storing the program information into a memory in a case where the received information is determined to be the program information; and

controlling the facsimile apparatus according to the program information,

wherein the program information received at said receiving step includes attribute information which indicates attributes of the program information.

12. The control method according to claim 11, wherein said program information includes an extended program.

13. The control method according to claim 12, wherein the extended program is for performing a self-diagnostic function.

14. The control method according to claim 11, wherein, at said determining step, the received information is determined to be the program information in accordance with detection of information, included in information for a facsimile control procedure, which indicates that the program information is to be transmitted.

15. The control method according to claim 11, wherein the program information stored in the memory is erased after elapse of a predetermined time period.

16. The control method according to claim 11, further comprising a designating step of designating a starting time,

wherein the facsimile apparatus is controlled in accordance with the program information received at said receiving step at the starting time designated at said designating step.

18. The control method according to claim 11, wherein the facsimile apparatus is controlled in accordance with the program information received at said receiving step when storage of the program information is completed.

19. The control method according to claim 11, wherein the program information is stored in a RAM separately from an already existing program information stored in a ROM.

20. The control method according to claim 19, wherein the RAM is the same as a RAM which stores the image information.

17. The control method according to clam 11, further comprising an input step of inputting an execution designation by an operator,

wherein the facsimile apparatus is controlled in accordance with the program information received at said receiving step in response to designation input at said input step.
