1.1 Terms of referenceDevelopments in image capture technology allow developers of multimedia applications to incorporate source material of varying physical characteristics. However the multimedia developer drawing up a specification for a capture system is faced with a bewildering choice of equipment for which there is little comparative information on the relationship between equipment specification and captured image quality. This report provides guidelines for decisions on the choice of appropriate capture pathways within the context of higher education.
Source material may vary from original objects such as biological specimens through hard copy sources like manuscripts, books, maps, photographic sources such as transparencies and film, to electronic sources like videotapes or video discs. There are a number of devices which can be used to capture images of the source material, although not all images can be captured by each device.
Six stages of image capture and processing were identified as follows:
In specifying a capture system it is necessary to achieve sufficient image quality to meet the required teaching/learning need within defined budgetary constraints. Quality as far as image capture is concerned is monitored by assessing three distinct facets of each image:
As equipment choice is likely to be constrained by budget, the implications of two cost scenarios on the quality of image capture were assessed. The two systems were chosen as follows:
1.2 Aims and objectives.The aims of the project were to evaluate a range of hardware and associated software options for the capture of images for two equipment cost scenarios as defined above, and to draw up guidelines for the selection of appropriate systems for image capture by developers of multimedia applications in higher education.
The objectives were to identify:
