• The other setting items registered to Preset 1 in advance are not changed. See "Preset Items and Image Setting File Items" (page 96) for the other setting items. Exposure Mode (EXPOSURE - MODE) Adjust the exposure settings. [Full auto]: The camera performs gain, iris, and shutter speed adjustments automatically. [Shutter priority]: The camera performs gain and iris adjustments automatically, and you can select shutter speed. [Iris priority]: The camera performs gain and shutter speed adjustments automatically, and you can select iris (aperture). [Manual]: You can manually adjust gain, iris, and shutter speed. Note Depending on the setting options, the range set by turning On/Off the high-sensitivity mode may differ. You cannot set the high-sensitivity mode from the menu. With reference to the Command List, change the setting from the VISCA/CGI command. Visibility Enhancer (VISIBILITY ENHANCER SETTING) In high-contrast scenes such as against a back light, this function reduces overexposure and underexposure. Selecting the checkbox enables the function. Effect (VISIBILITY ENHANCER - EFFECT) Set the level of Visibility Enhancer. Iris (EXPOSURE - IRIS) Select the iris value from the drop-down list. This function can be selected only when [Mode] is set to [Iris priority] or [Manual]. Gain (EXPOSURE - GAIN) Select the gain from the drop-down list. This function can be selected only when [Mode] is set to [Manual]. Auto gain Max. value (EXPOSURE - GAIN LIMIT) Select the maximum gain value of automatic exposure control from the drop-down list. This function can be selected only when [Mode] is set to [Full auto], [Shutter priority], or [Iris priority]. You cannot set the value lower than [Gain point level]. Gain point (EXPOSURE - GAIN POINT) When you set [Slowest] (lower limit of the shutter speed) to be lower than the output image frame rate, the shutter speed controls exposure based on the [Gain point] setting. Normally, when exposure is adjusted with sensitivity, noise is prominent when sensitivity is increased to brighten the image. You can decrease noise by adjusting the exposure through lower shutter speeds instead of adjusting with sensitivity. When the exposure is adjusted, select the checkbox of [Gain point] and set [Gain point level] to the value of sensitivity position that exposure is adjusted through shutter speeds. When shutter speeds reaches [Slowest] for exposure adjustment, sensitivity will increase again to adjust exposure. This setting is available when [Mode] is set to [Full auto] or [Iris priority]. Gain point level (EXPOSURE - POINT POSITION) This is enabled when the checkbox of [Gain point] is selected. When sensitivity during exposure adjustment reaches the value of [Gain point level], exposure will be adjusted through a lower shutter speed. You cannot select a value that exceeds [Auto gain Max. value]. This setting is available when [Mode] is set to [Full auto] or [Iris priority] and the checkbox of [Gain point] is selected. Shutter speed (EXPOSURE - SPEED) Select shutter speed from the drop-down list. This function can be selected only when [Mode] is set to [Shutter priority] or [Manual]. Note When you switch to the shutter speed value with a great change, it may take some time to apply the setting value. During that time, the setting value on the display does not match with the actual setting value. By reloading the web browser, the correct setting value is displayed. Fastest (EXPOSURE - MAX SPEED) Set the maximum shutter speed. This setting is available when [Mode] is set to [Full auto] or [Iris priority]. Slowest (EXPOSURE - MIN SPEED) Set the minimum shutter speed. This setting is available when [Mode] is set to [Full auto] or [Iris priority]. Auto slow shutter (EXPOSURE - SLOW SHUTTER) Select the checkbox to enable the auto slow shutter function. This function can be selected only when [Mode] is set to [Full auto]. 71
