· Noise reduction settings
Noise reduction settings are used to reduce or eliminate artifacts that can
limit the ability to positively identify an object. There are two types of
noise: luminance and color (chroma) noise. 3D noise reduction and 2D
noise reduction settings reduce luminance noise: dots of varying
brightness levels (black, white, and gray). It is not recommended to
completely eliminate luminance noise, which can result in unnatural
images. The 3D Noise Reduction and 2D Noise Reduction settings should
be configured after configuring Color Noise Reduction.
o Color Noise Reduction—Controls the noise appearing as red, green
and blue dots between light and dark areas. Four settings are available:
Off, Low, Mid, High. High maximizes the blending of the color noise with the image, effectively
removing the dots, while Low minimizes the blending.
o 3D Noise Reduction—Provides superior noise reduction and is recommended for use in extra low-
light conditions. It is especially useful for reducing blur with moving objects. 3D noise reduction
reduces image noise/snow in low-light conditions by comparing adjacent frames. A higher level of 3D
noise reduction generates relatively enhanced noise reduction, although it creates more motion blur
than 2D noise reduction on moving objects. Four settings are available: Off, Low, Mid, High.
o 2D Noise Reduction—Analyzes individual frames pixel by pixel and frame by frame to eliminate
environmental noise and deliver optimized image quality, especially in low-light conditions. 2D noise
reduction tends to produce superior results for moving objects when applied to areas in the field of
view where movement is present. However, it is less precise than 3D noise reduction. It can be set
On or Off.
· HLC (Highlight Compensation)—Detects areas of the image overexposed
by bright light sources such as headlights or spotlights and reduces image
exposure only in these areas to enhance overall image quality. HLC works
when Wide Dynamic Range Shutter is On.
· Stabilization (Electronic Image Stabilization)—To be supported in a
future release.
· Digital Zoom—Enable or disable digital zoom. Digital Zoom is not
available when Stabilization is On.
· Lidar Autofocus—Enable or disable the camera's laser focus
technology.
· Exposure Mode
Exposure is the amount of light detected by the image sensor and is
determined by the amount of time the shutter is open (shutter speed), and
other exposure parameters.
o Full Auto (default)—The camera completely opens its shutter and
automatically selects an exposure level using a programmed algorithm
to achieve a consistent exposure output. Exposure priority is given to
the iris. This mode is recommended for environments involving mixed lighting sources; for example,
indoor scenes where the main source is fluorescent lighting, combined with natural light that enters
the scene through windows and other exposed areas.
