Abstract

There is provided a digital camera to which external programs can be installed for appending desired functions thereto. Print image data generating programs to be stored in a recording medium in the digital camera are transmitted from a personal computer, an external extended recording medium of the digital camera, or an external device via a modem and a communication line. In any cases, the stored programs are read out at desired time to execute an print image data generating processing which transmits the print image data to a printer for printing the image. The stored program can be deleted at a desired time.

Claims

1. A function appending method for a digital camera which records image data by converting an image pickup light photoelectrically, comprising:

waiting for a program transmitting command from an external recording medium, wherein the program transmitting command is the first communication, which is between the digital camera and the external recording medium and which relates to a transmission of a program recorded on the external recording medium;

receiving the program transmitting command from the external recording medium;

transmitting a request-to-send program command to the external recording medium after receiving the program transmitting command;

receiving the program recorded on the external recording medium connected to the digital camera exchangeably;

storing the program into a recording medium provided in the digital camera;

reading the program from the recording medium in the digital camera at a desired time; and

executing the program.

2. The function appending method as set forth in claim 1, further comprising deleting a desired program from recording medium in the digital camera.

3. The function appending method as set forth in claim 1, wherein the program is a print image data generating program.

4. The function appending method as set forth in claim 1, wherein the program is a communication program.

5. The function appending method as set forth in claim 1, wherein the image data is recorded on the recording medium in the digital camera.

6. The function appending method as set forth in claim 1, wherein the recording medium is a flash memory.

7. A function appending method for a digital camera which records image data by converting an image pickup light photoelectrically, comprising:

waiting for a program transmitting command from an external recording medium, wherein the program transmitting command is the first communication, which is between the digital camera and the external recording medium and which relates to a transmission of a program recorded on the external recording medium;

receiving the program transmitting command from the external recording medium;

transmitting a request-to-send program command to the external recording medium after receiving the program transmitting command;

receiving the program recorded on the external recording medium and sent therefrom via a communication line,

storing the program into a recording medium provided in the digital camera;

reading the program from the recording medium in the digital camera at a desired time; and

executing the program.

8. The function appending method as set forth in claim 7, further comprising deleting a desired program from recording medium in the digital camera.

9. The function appending method as set forth in claim 7, wherein the program is a print image data generating program.

10. The function appending method as set forth in claim 7, wherein the program is a communication program.

11. The function appending method as set forth in claim 7, wherein the image data is recorded on the recording medium in the digital camera.

12. The function appending method as set forth in claim 7, wherein the recording medium is a flash memory.

13. The function appending method as set forth in claim 7, wherein the communication line is external to the digital camera.

14. The function appending method as set forth in claim 7, wherein the communication line is connected to an external device.

15. The function appending method as set forth in claim 14, wherein the external device comprises a personal computer.

16. The function appending method as set forth in claim 14, wherein the external device comprises a modem.

17. A digital camera for recording image data by converting an image pickup light photoelectrically, comprising:

external program reception unit with a program installing function, for waiting for a program transmitting command from an external recording medium, receiving the program transmitting command from the external recording medium, transmitting a request-to-send program command to the external recording medium after receiving the program transmitting command, receiving a program recorded on the external recording medium, which is connected thereto exchangeably, and storing the program into a recording medium provided in the digital camera; and

execution control unit for reading the program from the recording medium at a desired time to execute the read out program,

wherein the program transmitting command is the first communication, which is between the digital camera and the external recording medium and which relates to the transmission of the program recorded on the external recording medium.

18. The digital camera as set forth in claim 17, further comprising-program deleting unit for deleting a desired program from the recording medium provided therein.

19. The digital camera as set forth in claim 17, wherein the program is a program for generating print image data, and further comprising:

print data transmitting unit for transmitting the print image data generated by executing the program to a printing device.

20. The digital camera as set forth in claim 17, wherein the program is a communication program for communicating data with a terminal device connected to the communication line.

21. The digital camera as set forth in claim 17, wherein the image data is recorded onto the recording medium provided therein.

22. The digital camera as set forth in claim 17, wherein the recording medium is a flash memory.

23. A digital camera for recording image data by converting an image pickup light photoelectrically, comprising:

external program reception unit with a program installing function, for waiting for a program transmitting command from an external recording medium, receiving the program transmitting command from the external recording medium, transmitting a request-to-send program command to the external recording medium after receiving the program transmitting command, receiving a program recorded on the external recording medium and sent therefrom via a communication line, and storing the program into a recording medium provided in the digital camera; and

execution control unit for reading the program from the recording medium at a desired time to execute the read out program,

wherein the program transmitting command is the first communication, which is between the digital camera and the external recording medium and which relates to the transmission of the program recorded on the external recording medium.

24. The digital camera as set forth in claim 23, further comprising program deleting unit for deleting a desired program from the recording medium provided therein.

25. The digital camera as set forth in claim 23, wherein the program is a program for generating print image data, and further comprising:

print data transmitting unit for transmitting the print image data generated by executing the program to a printing device.

26. The digital camera as set forth in claim 23, wherein the program is a communication program for communicating data with a terminal device connected to the communication line.

27. The digital camera as set forth in claim 23, wherein the image data is recorded onto the recording medium provided therein.

28. The digital camera as set forth in claim 23, wherein the recording medium is a flash memory.

29. The digital camera as set forth in claim 23, wherein the communication line is external to the digital camera.
