During the last years the factor of the picture information to be evaluated rose much higher than the factor of available computing power. In order to use the data efficiently without expensive additional computer, an intelligent camera realize image (pre)processing itself. The camera transfers not only pictures but also data from computation-intensive steps of the image processing. Therefore several cameras can be connected to a PC without overloading.
Possible (Pre)processing steps are e.g.
- automatic brightness/ contrast control
- colour space adaptation
- motion detection
- on-screen display
- image compression
- image filter processing
- extensive image processing
Areas of application are among other things
- burglar and fire signalling
- surveillance of in-patient, buildings and construction sites
- license plate recognition
