Auto mode: The camera automatically sets the parameters; no need
for the operator to adjust.
Manual exposure time: Set the exposure time by yourself; the range is
Exposure Mode 0~10000.
Manual exposure gain: Set the exposure gain by yourself; the range is
0~1024.
All manual: Manually set the exposure time and gain.
This refers to the duration of pressing the shutter button. Increasing the
exposure time has the potential to enhance the signal-to-noise ratio,
resulting in clearer images. A longer exposure time allows for a greater
Exposure Time accumulation of photons on the CCD/CMOS surface, resulting in a
brighter captured image. However, overexposure can lead to
excessively bright photos, causing a loss of image details. Conversely,
underexposure may result in dark photos with insufficient details.
It refers to the amplification gain of the analog signal after double
sampling, but the noise signal is also amplified in the process of
Exposure Gain
amplifying the image signal. The gain is generally only used when the
signal is weak, but you do not want to increase the exposure time.
Auto mode: The camera automatically sets the contrast according to the
Contrast Mode environment; no need for the operator to adjust
Manual mode: Manually set the camera's contrast parameters.
It refers to the contrast between light and dark in the picture. By
increasing the contrast, the brighter areas will be brighter and the darker
Contrast
areas will be darker, and the contrast between light and dark will
increase.
Auto mode: The camera automatically sets the saturation according to
Saturation Mode the environment, without the need for the operator to adjust.
Manual mode: Manually set the camera's saturation parameters.
Saturation refers to the color. Adjusting the saturation will change the
color. The greater the adjustment, the more distorted the image color.
Saturation Adjusting the saturation is only suitable for pictures with insufficient
colors. When the saturation is adjusted to the lowest, the image will lose
its color and become a black and white image.
Auto mode: The camera automatically sets the sharpness according to
Sharpness
the environment; no need for the operator to adjust.
Mode
Manual mode: Manually set the sharpness parameters of the camera.
Sharpness is sometimes called "sharpness", which is an indicator that
Sharpness reflects the sharpness of the image plane and the sharpness of the
edges of the image. If you increase the sharpness, the contrast of the
