IS 2000 A image acquisition and processing system used to illustrates the architecture concepts. Basic functionality of the product is to capture an image using the camera on the probe.

Hardware configuration Figure 2. 1, PAGE 24

System Overview The source of the image could be from visible light, from another frequency in the electromagnetic spectrum, from heat, or from some other source of radiation. User may wish to take a single image, a series of images at different time intervals, or to create a motion picture.

System Overview(2) The user may wish to keep the camera stationary or move it. (Acquisition procedures). The system has a set of built-in acquisition procedures. When a procedure is underway, the user is able to monitor it by viewing the raw data. Users can perform a number of processing operations to enhance the images. Users can transfer them to a remote imaging system for remote viewing processing.

Product Features(1) Provides a range of image acquisition and processing operations on twodimensional and three-dimensional images, data storage, and network access. n n n User-friendly operator environment. Comprehensive catalog of built-in acquisition procedures. Custom acquisition procedure definition.

Product Features(2) The throughput of image acquisition is 50 percent higher than for previous products. Image display can be as fast as the maximum hardware speed. Runtime trade-off between acquisition speed and image quality.

Product Features(3) Easy upgrade to new platforms. Open platform connectivity to on-site or remote workstations. Connection to peripherals, including printers and digital imagers.

System Interactions IS 2000 interacts with: n n n Users: User control panel. The object being probed: probe hardware network connecting the system to other stations: Network connector.

The future of IS 2000 Design to be extensible, maintainable, and portable. Flexible enough to accommodate certain expected changes: n n Product requirements Physical characteristics of probe/camera The way the users use this system. Image processing method, file formats, standards

Using This system to demonstrate… In the next five chapters, we present how the design of IS 2000’s software architecture meets these challenges. Some of the design constraints are ones every software designer faces Some of them are unique to the IS 2000 functionality and marketplace.
