§
Minimum Shutter Speed
—Select the slowest shutter speed based on the amount of light in the
scene. A slower shutter speed increases the amount of light entering the sensor and results in a
brighter, more-detailed image. The Video Format determines the minimum shutter speeds
available, listed in the following table from slowest to fastest, in fractions of a second:

—Select the fastest shutter speed based on the amount of light in the
scene. A faster shutter speed decreases the amount of light entering the sensor and results in a
darker image. The Video Format determines the maximum shutter speeds available, listed in the

the mode.
§
Mode
—Specify the power used for lighting the scene, 50Hz or 60Hz.
o
Manual
—Specify a fixed shutter speed and the gain.
§
Gain
—A higher value increases the sensitivity of the image sensor, which brightens the image and
adds details, but also increases the noise level. Define a value between 0-100.
