Automatic Scan Converter for Display Systems

Description

A scan converter capable of converting from any of several input scan formats to a fixed output format, which may or may not have the same number of lines as the input, derives a current displayed (output) field or frame by interpolation from the current field of an input whose vertical scan frequency is the same as that of the output. The converter recog- nizes the number of lines in the input and automatically derives the ap- propriate interpolation routine to make the conversion to a desired fixed output format. Because the vertical scan frequency is the same for the input and output, o.nly a few lines of storage, instead of the frame store usually required, are needed to accomplish conversion with results com parable to that attainable when a full frame of information is stored.

Advantages

• Ability to automatically convert from any of several input scan formats to a fixed output format in displays

Potential Applications

• A system to automatically convert from any of several input scan formats to a fixed output format to be used in information displays including televisions and computer screens
