ANALOG BUFFER MEMORY FOR HIGH-SPEED DIGITAL IMAGE CAPTURE
First Claim
Patent Images
1. A digital imaging system comprising:
- an image sensor;
image processing and compression circuits; and
an analog/multi-level memory coupled between said image sensor and said image processing and compression circuits to receive and temporarily store analog data from said image sensor and transmit said analog data to said image processing and compression circuits.

Abstract
A digital imaging system uses a high density, high speed analog/multi-level memory to temporarily store image data at high rates for extended periods of time. A portion of the stored data is transmitted for image processing and compression. When image processing and compression on the data are completed, another portion of the stored data is transmitted for processing. As a result, high speed image capture for extended periods is possible because the processing speed of the image processing and compression no longer limit the time required between high speed bursts or the length of a high speed burst.
