Abstract
An image quality improvement method is applied to an operation processor of a surveillance system and includes driving a first light source of the surveillance system to emit a first illumination beam, driving an image camera of the surveillance system to capture a first image relevant to the first illumination beam, and deciding whether to drive a second light source of the surveillance system to emit a second illumination beam and/or decide an illumination intensity of the second illumination beam in accordance with an analysis result of the first image.
Claims20
An image quality improvement method applied to an operation processor of a surveillance system, the image quality improvement method comprising:
- the operation processor driving a first light source of the surveillance system to emit a first illumination beam;
- the operation processor driving an image camera of the surveillance system to capture a first image relevant to the first illumination beam;
- and
- the operation processor deciding whether to drive a second light source of the surveillance system to emit a second illumination beam and/or decide an illumination intensity of the second illumination beam in accordance with an analysis result of the first image;
- wherein the first illumination beam of the first light source and the second illumination beam of the second light source have different wavelength ranges.
A surveillance system, comprising:
- a first light source adapted to emit a first illumination beam;
- a second light source adapted to emit a second illumination beam having a wavelength range different from a wavelength range of the first illumination beam;
- an image camera having an imaging range relevant to the first light source and the second light source;
- and
- an operation processor electrically connected to the first light source and the second light source and the image camera, the operation processor being adapted to drive the first light source to emit a first illumination beam, drive the image camera to capture a first image relevant to the first illumination beam, and decide whether to drive the second light source to emit a second illumination beam and/or decide an illumination intensity of the second illumination beam in accordance with an analysis result of the first image.
