A scaler is an electronic device that converts a video or computer-video signal of one resolution to another, typically higher resolution. In general use, a video scaler is used to convert composite video, S-video, or component video and, in some cases, RGB computer-video signals, to a computer-video resolution that matches the native resolution of a plasma or LCD monitor, or data projector.

Scan converters, on the other hand, do just the opposite: they convert a high resolution computer-video signal to match the low resolution needs of NTSC or PAL video, so that the computer image can be viewed on a television or recorded on a VCR or DVD.
