Operation
• Manual: Opens the iris completely with a fixed gain. This mode should only be used in indoor scenes
with consistent lighting. Manual mode requires the user to set fixed values for shutter and gain
levels. Increasing the value of the fixed shutter increases the amount of light entering the sensor,
which allows a brighter and more detailed image. In a similar manner, utilizing gain and increasing
its level increases the sensitivity of the image sensor, which brightens the image and add details.
This increases the level of noise in the image.
Shutter WDR: For scenes with high contrast or changing light conditions, the camera combines two
•
frames taken with slow- and fast-exposure shutter speeds into a single frame with a wide dynamic
range. The camera uses an algorithm that determines the optimal mix of light and dark regions
within the scene.
