EXPOSURE VALUE (EV)
The exposure value is the result of an internal algorithm, using sensor
analog gain, digital gain and exposure time to adjust the image’s perceived
brightness. EV adjustments are based on a scale of -2.5 to +1.5 with 0.5 steps.
Image brightness in system performance is subjective. Note: Image brightness
is different than display brightness (which can be adjusted using the ON/OFF
knob).
In general, a low EV value will provide best results when used in a bright scene
with high dynamic range, providing a dampening effect to high brightness
areas of the image. Using a low EV setting allows the user to better see a
region in the image that is too bright.
A high EV value is best used in a low light scene with a low dynamic range.
The high EV value will boost the signal and increase low light sensitivity. Using
a high EV setting will allow the user to better see a region in the image that is
too dark. In a very low light scene, the higher EV value will also increase scene
noise, therefore its best to find a balance between low light performance and
signal to noise ratio.
