Abstract

A system and method for sending a packet with a position address and line scan data from a first device over a 1394 interface to a second device. The present invention loads a camera, an illuminator, and a microprocessor with set-up instructions and a start pulse. The camera captures a line-by-line image of an object placed on the surface of a sliding prism. Position data, corresponding to the captured line-by-line image, is logged as the position address. The position address is combined with the line-by-line image to form a packet. The packet is sent to the second device for processing and viewing the image.

Claims

1. A method for sending a packet with a position address and line scan data from a first device over a 1394 interface to a second device, comprising the steps of:

(a) loading a camera, an illuminator, and a microprocessor with set-up instructions and a start pulse;

(b) capturing a line-by-line image of an object placed on a sliding prism;

(c) logging position data corresponding to the line-by-line image, wherein the position data is referred to as the position address;

(d) combining the line-by-line image with the corresponding position address to form a packet; and

(e) sending the packet to the second device.
