Abstract

A medical image transfer and control system of the present invention preferably utilizes a medical image snap-shot formatting device. This device generally includes a digital signal processor and a signal formatting component that is operably connected to the digital signal processor. The signal formatting component is designed to receive medical image snap-shot data from a camera and, if necessary, format the data to a digital format. The signal formatting component then forwards the digital data to the digital signal processor which operates to compress the data to a format suitable for transfer over a plain old telephone system (POTS).

Claims

1. A low-cost, medical image snap-shot formatting device, comprising:

an operations system;

a remote installation;

a camera; and

a non-camera peripheral;

wherein the operations system comprises an image processing circuit and a videophone, the image processing circuit comprising a first digital signal processor operably coupled to a first signal formatting component, the first digital signal processor operating under control of a first pre-determined program and a second digital signal processor operating under control of a second pre-determined program, said second digital signal processor operably coupled to said first digital signal processor,

wherein said first signal formatting component is capable of receiving medical image snap-shot data from the camera and, wherein upon said first signal formatting component receiving said medical image snap-shot data, the first signal digital signal processor formats said medical image snap-shot data into a digital format, if said medical image snap-shot data is not already in a digital format, and supplies the digitally formatted medical image data to said second digital signal processor in both a first thumbnail image suitable for transfer over a plain old telephone system and a second high-resolution snap-shot image suitable for transfer over a plain old telephone system;

wherein said second digital signal processor supplies the first thumbnail image to the videophone wherein a videophone processor transmits the first thumbnail image to the remote installation over the plain old telephone system and wherein the second digital processor stores the second high-resolution snap-shot image in an image memory;

wherein the remote installation comprises a video display and a communication device whereupon said remote installation receives and displays said first thumbnail image and wherein said communication device communicates over the plain old telephone system to selectively request transmission of the second high-resolution image or the taking of a new medical image with the camera.

2. The device of claim 1, wherein said first thumbnail image is compressed to a range of 90%-99% of said high-resolution snap-shot image.

3. The device of claim 1, wherein said medical image snap-shot data is in a format selected from a group consisting of:

USB, S-video, and composite video.

4. The device of claim 1, wherein said device is implemented within a patient system of a telemedicine system.

5. The device of claim 1, further comprising a synchronizing device that is operably coupled intermediate said first digital signal processor and said first signal formatting component.

6. The device of claim 5, wherein said synchronizing device comprises a field programmable gate array.

7. The device of claim 1, further comprising a second signal formatting component wherein said second signal formatting component receives said medical image snap-shot data and formats said medical image snap-shot data into an NTSC format, if said medical image snap-shot data is not already in said NTSC format.

8. The device of claim 1, wherein said first digital signal processor compresses according to an adjustable compression loss percentage.
