Abstract

Roughly described, a portable, removable memory device also includes a display for rendering images stored in the memory device in standalone mode. The memory device has a standard attachment interface to enable attachment and communication with different kinds of hosts. It also includes at least sufficient intelligence to be able to transform image file formats to satisfy user preferences or the requirements of different hosts. The device can be used as an interchangeable memory card, and also as a simple and easy way of sharing digital images.

Claims

1. A sharable, portable memory device comprising:

a first memory card having a memory;

a display on the card;

a communications interface on the card for establishing a user-severable communication link between the memory device and a plurality of different hosts at different times, wherein one of the hosts comprises a digital camera device; and

a controller on the card operable in response to user input to;

store in the memory an image received from a first one of the hosts via the communication link while the portable device is in communication with the first host,

render on the display an image represented in a file in the memory at least while the portable device is operating standalone and not in communication with any host, and

transform an image in the memory from a first image file format to a second image file format.
