Abstract

An electronic device includes an image capturing unit configured to generate captured data, a display unit, a communication unit configured to transmit image data based on the generated captured data to an external device, and a controller. When transmitting first image data resulting in a first delay on transmitting the first image data to the external device, the controller causes an image which corresponds to the first image data and is based on the captured data to be displayed on the display unit. When transmitting second image data resulting in a second delay larger than the first delay on transmitting the second image data to the external device, the controller causes an image other than an image corresponding to the second image data to be displayed on the display unit.

First claim

The invention claimed is:

1. An electronic device capable of transmitting image data to an external device for display, the electronic device comprising:
an image capturing unit configured to generate captured data;
a display unit;
a communication unit configured to transmit image data based on the generated captured data to the external device; and
a controller configured to control the display unit, wherein:
when transmitting first image data resulting in a first delay on transmitting the first image data to the external device, the controller causes an image which corresponds to the first image data and is based on the captured data to be displayed on the display unit, and
when transmitting second image data resulting in a second delay larger than the first delay on transmitting the second image data to the external device, the controller causes an image other than an image corresponding to the second image data to be displayed on the display unit to avoid a display timing difference between the display unit and the external device.

2. The electronic device according to claim 1 , wherein
when the external device receives an image from the electronic device, the external device causes the received image to be displayed on an external display device.

3. The electronic device according to claim 1 , wherein
the image other than the second image is an image including an operation button for remotely operating the external device.

4. The electronic device according to claim 1 , wherein
the first image is an image having a first resolution, and the second image is an image having a resolution higher than the first resolution.

5. The electronic device according to claim 1 , wherein
the second image is an image that is read from a predetermined recording medium and then reproduced.

6. An electronic device capable of transmitting image data to an external device for display, the electronic device comprising:
an image capturing unit configured to generate captured data;
a display unit;
a communication unit configured to transmit image data based on the generated captured data to the external device; and
a controller configured to control the display unit, wherein:
the controller has a recording mode for recording image data based on the captured data generated by the image capturing unit, and a playback mode for reproducing image data recorded in a predetermined recording medium,
in the recording mode, the controller transmits an image based on the captured data which is generated by the image capturing unit to the external device through the communication unit, and causes the image based on the captured data generated by the image capturing unit to be displayed on the display unit, and
in the playback mode, the controller transmits the image data recorded in the predetermined recording medium to the external device through the communication unit, and causes no image based on the image data recorded in the predetermined recording medium to be displayed on the display unit to avoid a display timing difference between the display unit and the external device.

7. The electronic device according to claim 2 , wherein the external display device includes at least one of (i) a part of the external device, and (ii) a device releasably connectable to the external device.

8. The electronic device according to claim 6 , wherein the image transmitted in the recording mode has a first resolution, and the image transmitted in the playback mode has a second resolution which is higher than the first resolution.
