IRIS
In the camera, IRIS refers to the aperture. Iris is an important factor in determining depth, which
improves image quality and depth so that you can see both distant and near objects clearly.
GAIN
It is a function to electronically amplify the signal when the light source is not illuminated enough and
the image signal level is not enough. It is used when there is insufficient light on screen even if all iris
is open. However, since the amplification is forcibly amplified by using the electrical characteristics,
noise may occurs and may be a deterioration of image quality.
Shutter Speed
This function sets the opening time of the shutter. Only when the shutter is open, the light is
transmitted to the image sensor and the image is taken. For example, the lower the shutter speed is,
the more vivid the dynamic image can be.
Digital ZOOM
This function enlarges a part of image data by digital processing method and obtains zoom effect.
Because it is software based rather than using hardware(lens), image quality deteriorates. It is
commonly used as a supplement to optical zoom.
BAUDRATE
It is the data transmission rate which indicates how many bits are transmitted per second to
communicate. If the baudrate is 9600 bps, it means that 9600 bits are transmitted per second.
GAMMA
Gamma is a figure of the response characteristics between the image brightness which is between
the camera and the display receiving the input and the voltage. It is a function to ensure the contrast
of the image when the signal sent from the camera is displayed on the display.
