Abstract

A digital image display device for displaying a collection of digital images, comprising: a display screen; a processor; a power control circuit for enabling an active display mode for displaying digital images on the display screen and a reduced power mode wherein the display screen does not display digital images; a network interface for communicating with a network; an image memory for storing digital images; and a processor-accessible program memory. The program memory stores executable instructions for causing the processor to execute the steps of: receiving one or more digital images from a network server using the network interface; storing the received digital images in the image memory; if the power control circuit is in the reduced power mode when the digital images are received setting it to operate in the active display mode; and displaying the stored received digital images on the display screen.

Claims

1. A digital image display device for displaying a collection of digital images, comprising:

a display screen;

a processor;

a power control circuit for enabling an active display mode for displaying digital images on the display screen and a reduced power mode wherein the display screen does not display digital images;

a network interface for communicating with a network;

an image memory for storing digital images; and

a processor-accessible program memory storing executable instructions for causing the processor to execute the steps of;

a) receiving one or more digital images from a network server using the network interface;

b) storing the received digital images in the image memory;

c) if the power control circuit is in the reduced power mode when the digital images are received setting it to operate in the active display mode; and

d) displaying the stored received digital images on the display screen.

2. The digital image display device of claim 1 wherein the processor-accessible program memory further stores executable instructions for causing the processor to execute the additional step of:

e) if the power control circuit was in the reduced power mode setting in step c), resetting the power control circuit to the reduced power mode after displaying the stored received digital images.

3. The digital image display device of claim 2 wherein the stored received digital images are displayed for a predetermined period of time before resetting the power control circuit to the reduced power mode.

4. The digital image display device of claim 2 wherein the stored received digital images are each displayed a predetermined number of times before resetting the power control circuit to the reduced power mode.

5. The digital image display device of claim 1 further including a real-time clock providing a time of day, and wherein a default behavior of the power control circuit is controlled responsive to the time of day.

6. The digital image display device of claim 5 further including a user interface enabling a user to define a default behavior of the power control circuit including specifying one or more time of day intervals during which the power control circuit will be set to operate in the reduced power mode.

7. The digital image display device of claim 6 wherein at least one of the specified time of day intervals is designated to be an inactive time of day interval during which the power control circuit will continue to operate in the reduced power mode if any digital images are received from the server using the network interface.

8. The digital image display device of claim 7 wherein if any digital images are received from the server using the network interface during an inactive time interval, then when the inactive time interval ends the power control circuit is set to operate in the active display mode and the stored received digital images are displayed on the display screen.

9. The digital image display device of claim 5 further including receiving over the network interface a set of parameters defining a default behavior of the power control circuit including parameters specifying one or more time of day intervals during which the power control circuit will be set to operate in the reduced power mode.

10. The digital image display device of claim 9 wherein at least one of the specified time of day intervals is designated to be an inactive time of day interval during which the power control circuit will continue to operate in the reduced power mode if any digital images are received from the server using the network interface.

11. The digital image display device of claim 10 wherein if any digital images are received from the server using the network interface during an inactive time interval, then when the inactive time interval ends the power control circuit is set to operate in the active display mode and the stored received digital images are displayed on the display screen.
