Abstract

The object of the present invention is, while employing only a simple structure, to engage in rapid communication with an external device and to display results of the communication. According to the present invention, disclosed is an electronic apparatus, which comprises conversion means for converting a target image into image signals, supply means for supplying, to a monitor, signals in consonance with the image signal obtained by the conversion means in order to reproduce the target image, communication means for using a DS-Link method to perform bidirectional communication with an external device handling the image signal for the target image and control means for displaying on the monitor information concerning the external device that is obtained by the communication means.

Claims

1. A camera which is battery-operated and integrally contains a monitor, said camera comprising:

reproducing means for reproducing an image recorded on a recording medium and generating an image signal;

supply means for supplying the image signal to a monitor having a backlight;

communication means for transmitting the image signal to a printer, and for receiving a signal indicating abnormality from the printer, via two-way communication; and

control means for controlling operation so as to turn off the backlight of the monitor when image data is transmitted to the printer by said communication means, after the transmission of the image signal and during printing of the image signal by the printer, thereby saving power and comprising power-savings-interruption means for interrupting the power savings during printing due to a printer abnormality by turning on the backlight in response to receipt of the signal indicating abnormality in the printer via said communication means.

2. A camera according to claim 1, wherein

the printer starts a print operation in response to reception of the image signal, and

said control means controls operation so as to turn on the backlight in response to occurrence of abnormality in the printer after the start of a print operation by the printer.

3. A camera according to claim 1, wherein the printer transmits a command indicating a lack of ink and, in response to reception of the command, said control means controls operation so as to turn on the backlight and so as to perform a warning display.

4. A control method for a camera which is battery-operated and integrally contains a monitor, said method comprising:

a reproducing step of reproducing an image recorded on a recording medium and generating an image signal;

a supply step of supplying the image signal to a monitor having a backlight;

a communication step of transmitting the image signal to a printer, and receiving a signal indicating abnormality from the printer, via two-way communication; and

a control step of controlling operation so as to turn off the backlight of the monitor when image data is transmitted to the printer in said communication step, after the transmission of the image signal, and during printing of the image signal by the printer, thereby saving power and comprising a power-savings-interruption step for interrupting the power savings during printing due to a printer abnormality by turning on the backlight in response to receipt of the signal indicating abnormality in the printer in said communication step.

5. A control method according to claim 4, wherein

the printer starts a print operation in response to reception of the image signal, and

said control step controls operation so as to turn on the backlight in response to occurrence of abnormality in the printer after the start of a print operation by the printer and also to turn off the backlight of the monitor after transmitting the image signal and during printing of the image signal by the printer.

6. A control method according to claim 4, wherein the printer transmits a command indicating a lack of ink and, in response to reception of the command, said control step controls operation so as to turn on the backlight and to perform a warning display.

7. A print system in which a camera that is battery-operated and integrally having a monitor with a backlight communicates with a printer, wherein:

said camera includes;

reproducing means for reproducing an image recorded on a recording medium and generating an image signal,

supply means for supplying the image signal to said monitor, and

communication means for transmitting the image signal to said printer and for receiving a signal indicating abnormality from said printer, via two-way communication,

said printer starts a print operation in response to reception of the image signal, and

said camera further includes control means for controlling operation so as to turn off the backlight of said monitor when image data is transmitted to said printer by said communication means, after the transmission of the image signal, and during printing of the image signal by the printer, thereby saving power and comprising power-savings-interruption means for interrupting the power savings during printing due to a printer abnormality by turning on the backlight in response to receipt of the signal indicating abnormality in the printer via said communication means.

8. A print system according to claim 7, wherein

the printer starts the print operation in response to reception of the image signal, and

said control means controls operation so as to turn on the backlight in response to occurrence of abnormality in said printer after the start of a print operation by said printer.

9. A print system according to claim 7, wherein

said printer transmits a command indicating a lack of ink, and

in response to reception of the command, said control means controls operation so as to turn on the backlight and to perform a warning display.

10. A control method for a print system in which a camera that is battery-operated and integrally having a monitor with a backlight communicates with a printer, wherein, in the camera, said method includes:

a reproducing step of reproducing an image recorded on a recording medium and generating an image signal,

a supply step of supplying the image signal to the monitor,

a communication step of transmitting the image signal to the printer, and receiving a signal indicating abnormality from the printer, via two-way communication, upon the printer starting a print operation in response to reception of the image signal, and

a control step of controlling operation so as to turn off the backlight of the monitor when image data is transmitted to the printer in said communication step, after the transmission of the image signal, and during printing of the image signal by the printer, thereby saving power and comprising a power-savings-interruption step for interrupting the power savings during printing due to a printer abnormality by turning on the backlight in response to receipt of the signal indicating abnormality in the printer via said communication step.

11. A camera which is battery-operated and integrally contains a monitor, said camera comprising:

supply means for supplying an image signal according to a reproduced target image to said monitor having a backlight;

communication means for transmitting the image signal to an external apparatus via two-way communication; and

control means for controlling operation so as to turn off the backlight of the monitor when image signal is transmitted to the external apparatus, after the transmission of the image signal, and during printing of the image signal, thereby saving power and comprising power-savings-interruption means for interrupting the power savings during printing due to an external-apparatus abnormality by turning on the backlight in response to receipt of signal indicating abnormality in the external apparatus via the communication means.

12. An camera according to claim 11, wherein the external apparatus is a printer, and the printer starts a print operation in response to reception of the image signal.
