Abstract

Methods and apparatus for providing portable photographic images are described. The present invention includes a small, portable electronic display unit that may be placed within a wallet or purse. The display unit may include an input port for downloading digital images from a computer or digital camera. The display unit may also include one or more buttons to provide a user with the ability to select an image for display from a given set of digital images that have been stored in memory. The display unit may be preloaded with one or more digital images, or it may be configured to be loaded by a user. The digital images may, for example, include still digital photographs or short video clips that have been captured from a digital camera.

Claims

1. A portable device, comprising:

an electronic display capable of displaying digital images stored in memory;

a case that fits within a pocket-sized wallet and provides support for the electronic display, the case comprising a first planar surface and a second planar surface substantially parallel to one another;

a segment located on the second planar surface operable to receive a memory card

at least one index button;

processing circuitry operable to display at least one digital image on the electronic display, wherein the processing circuitry is coupled to the memory, the at least one index button, and the electronic display; and

a magnetic strip that includes credit card information, wherein the segment is located below the magnetic strip.

2. The portable device of claim 1, wherein the at least one index button is located below the electronic display.

3. The device of claim 1, wherein the processing circuitry is an application specific integrated circuit (ASIC).

4. The device of claim 1, wherein the processing circuitry is a programmable logic device (PLD).

5. The portable device of claim 1, wherein the at least one index button comprises a first index button and a second index button.

6. The portable device of claim 5, wherein:

the first index button allows a forward review of the digital images stored in memory; and

the second index button allows a backwards review of the digital images stored in memory.

7. The portable device of claim 1, wherein the magnetic strip is operable to be swiped through a credit card reader.

8. The portable device of claim 1, wherein the case further comprises:

a region of uniform thickness between the first planar surface and the second planar surface.

9. The portable device of claim 1, wherein the electronic display and the at least one button are located on the first planar surface.

10. The portable device of claim 1, further comprising:

an I/O port located proximate to the at least one index button and below the electronic display on the first planar surface.

11. The portable device of claim 1, wherein the electronic display comprises a flexible liquid crystal display.

12. The portable device of claim 1, wherein the memory card is operable to connect to the processing circuitry via a connector located on the second planar surface.
