•“Illumination” is a group of options to adjust camera’s white balance computation to the illumination of the scene. “Automatic” enables the camera to adjust for illumination automatically.
“Lighting” is a group of options to adjust camera’s auto exposure computation to the oscillation frequency of the indoor lighting: European (50 Hz) or US/Japan (60 Hz).
“Low Light Mode” is a group of options to adjust camera’s operation under low light conditions:
a.“High Speed” is to enable the shortest exposure time, selectable from a drop- down list “Short Exposure” between 1 and 10 ms, and the maximum frame rate. This option will reduce motion blur, but may result in a noisier
b.“Speed” is to enable short exposure time not exceeding 10 ms by raising video gain as much as possible unless the low light conditions require a further time increase (up to 80 ms).
c.“Balanced” is to enable medium- duration exposures up to 20 ms by raising video gain as much as possible unless the low light conditions require a further time increase (up to 80 ms).
d.“Quality” is to enable longer exposures up to 40 ms, by raising video gain as much as possible unless the low light conditions require a further time increase (up to 200 ms). Motion blur may become high, but video will contain less noise under low light conditions.
e.“Moon Light ™ is to enable very long exposures up to 500 ms if necessary.
