Setting the Switchover of USER SW GAIN

AJ-HPX3100 allows three other modes to be used in addition to the L/M/H standard gain settings: the analog gain-up S.GAIN (super gain) mode to achieve a gain of 30 dB or more, the cumulative gain-up DS.GAIN (digital super gain) mode which uses progressive drive.

To select these functions, perform menu operations to select the S.GAIN item and DS.GAIN item, and preset the gain to be used for each item. These menu items are found in the <USER SW GAIN> screen on the CAM OPERATION page. For instance, if the S.GAIN and DS.GAIN functions have been allocated to the USER MAIN button, USER1 button or USER2 button, the gain can be increased by using these buttons in combination with the USER buttons.

1)To increase the gain without increasing noise: The DS.GAIN function is used.2)To increase the normal analog gain: (noise is increased)

Use the S.GAIN feature alone.

‹Note

Note that the accuracy of AUTO IRIS, White Balance, and Black Balance may be influenced by an increase in noise.

3) To achieve ultra-high sensitivity:

Use the S.GAIN function and DS.GAIN function in combination. However, exercise care during operation since image lag will become more conspicuous with moving subjects the more the gain is increased by using the DS.GAIN function.

When shooting moving subjects, keep the gain increase with the DS.GAIN function to under 12 dB:.

Settings Options and Usage

S.GAIN: An analog gain increase with an asterisk is one that is valid. One without an asterisk is invalid.

DS.GAIN: A cumulative gain increase with an asterisk is one that is valid. One without an asterisk is invalid.
