Abstract

A display device having a plurality of display modes may be used with a recording apparatus which records received image information on a recording medium. An information display is provided for displaying data. Exposure correction circuitry corrects an exposure characteristic of the received image and provides exposure correction information in response to a setting operation. Circuitry is provided for generating an identification code to be recorded on the recording medium together with the image information. Control circuitry is provided having a first display mode for causing the display to display the correction information from the exposure correction circuitry when the exposure correction information has been set, and a second display mode for causing the display to display the identification code generated by the generating circuitry instead of the correction information when the exposure correction information has not been set.

Claims

1. A camera apparatus for recording received image information, comprising:

recording means for recording the image information;

information display means for displaying data;

exposure correction means for correcting an exposure characteristic of said image information, and for providing exposure correction information in response to a setting operation;

means for generating an identification code to be recorded together with the image information; and

control means having a first display mode for causing said information display means to display the correction information from said exposure correction means when the exposure correction information has been set, and a second display mode for causing said information display means to display the identification code generated by said generating means instead of said correction information when the exposure correction information has not been set.

2. An apparatus according to claim 1, wherein said information display means comprises a liquid crystal display panel.

3. An apparatus according to claim 1, further comprising conversion means for converting said image into an electrical image signal, and wherein an exposure correction means is adapted to effect exposure correction by correcting a conversion characteristic of said conversion means.

4. An apparatus according to claim 1, wherein said identification code comprises a 4-digit number.

5. An apparatus according to claim 1, further comprising:

a manual setting member for manually setting either said first display mode or said second display mode;

wherein said control means is adapted to switch between said first and second display modes in response to the setting of said manual setting member.

6. An apparatus according to claim 1, wherein said recording means records said image information on a recording medium.

7. An apparatus according to claim 6, wherein said recording medium comprises a disk shaped medium.

8. An apparatus according to claim 6, wherein said recording means comprises magnetic recording means.

9. A camera apparatus comprising:

a first display element for displaying a first recording mode;

a second display element for displaying a second recording mode different from said first recording mode;

setting means for setting said first or second recording mode, or a third recording mode different from said first and second recording mode;

a third display element different from said first and second display elements; and

control means for causing said first and second display elements to respectively display the first and second modes when said first or second mode is set by said setting means, and for causing said third display element to perform a display together with said first or second display element when said third mode is set.

10. An apparatus according to claim 9, wherein said first, second and third display elements are provided on a common display panel.

11. An apparatus according to claim 9, wherein said first and second display elements are adapted to display characters corresponding to said first and second modes respectively.

12. An apparatus according to claim 11, wherein said third display element is adapted to display a message "OFF".

13. An apparatus according to claim 9, wherein said setting means comprises a manually operable member.

14. A camera apparatus for receiving an image and recording image information corresponding to the image, comprising:

recording means for recording the image information;

information display means for displaying data;

means for generating an identification code to be recorded together with said image information; and

switch means for selecting either a first display mode for causing said information display means to display the identification code generated by said generating means, or a second display mode for causing said information display means to display image display characteristics of said apparatus instead of said identification code, wherein said second display mode displays information on an exposure state of said image.

15. An apparatus according to claim 14, wherein said information display means comprises a liquid crystal display panel.

16. An apparatus according to claim 14, wherein said identification code comprises a 4-digit number.

17. An apparatus according to claim 14, further comprising:

a manual setting member for manually setting either said first display mode or said second display mode;

wherein said control means is adapted to switch between said first and second display modes in response to the setting of said manual setting member.

18. An apparatus according to claim 14, wherein said recording means records said image information on a recording medium.

19. An apparatus according to claim 17, wherein said recording medium comprises disk shaped medium.

20. An apparatus according to claim 17, wherein said recording means comprises magnetic recording means.

21. A camera apparatus for recording in a memory means information corresponding to a received image, comprising:

recording means for recording the image information;

information display means having segments indicating a polarity;

exposure correction means for correcting an exposure of said image and providing correction information;

detection means for detecting a remaining amount of the memory means and providing information corresponding thereto; and

control means provided with a first display mode for causing said information display means to display the correction information from said exposure correction means, and a second display mode for causing said display means to display the information from said detection means instead of said correction information without using said polarity segments.

22. An apparatus according to claim 21, wherein said recording means causes said memory means to record information corresponding to said image.

23. An apparatus according to claim 21, wherein said information display means comprises a liquid crystal display panel.

24. An apparatus according to claim 21, further comprising conversion means for converting the received image into an electrical image signal;

wherein said exposure correction means is adapted to effect exposure correction by correcting a conversion characteristic of said conversion means.

25. An apparatus according to claim 21, further comprising:

a manual setting member for manually setting either said first display mode or said second display mode;

wherein said control means is adapted to switch between said first and second display modes in response to the setting of said manual setting member.

26. An apparatus according to claim 21, wherein said memory means comprises a disk-shaped recording medium.
