SPEED (Exposure - Shutter speed) When [MODE] is either [MANUAL] or [SHUTTER Pri], select the electronic shutter speed. When the signal format is 59.94 or 29.97 You can choose from [1/1], [2/3], [1/2], [1/3], [1/4], [1/6], [1/8], [1/10], [1/15], [1/20], [1/30], [1/50], [1/60], [1/90], [1/100], [1/125], [1/180], [1/250], [1/350], [1/500], [1/725], [1/1000], [1/1500], [1/2000], [1/3000], [1/4000], [1/6000], [1/10000]. When the signal format is 50 or 25 You can choose from [1/1], [2/3], [1/2], [1/3], [1/4], [1/6], [1/8], [1/12], [1/15], [1/20], [1/25], [1/30], [1/50], [1/60], [1/100], [1/120], [1/150], [1/215], [1/300], [1/425], [1/600], [1/1000], [1/1250], [1/1750], [1/2500], [1/3500], [1/6000], [1/10000]. When the signal format is 23.98 You can choose from [1/1], [2/3], [1/2], [1/3], [1/4], [1/6], [1/8], [1/12], [1/20], [1/24], [1/25], [1/40], [1/48], [1/50], [1/60], [1/96], [1/100], [1/120], [1/144], [1/192], [1/200], [1/288], [1/400], [1/576], [1/1200], [1/2400], [1/4800], [1/10000]. IRIS (Exposure - Iris) When [MODE] is either [MANUAL] or [IRIS Pri], you can change the iris setting. You can choose from [F2.0], [F2.2], [F2.4], [F2.6], [F2.8], [F3.1], [F3.4], [F3.7], [F4.0], [F4.4], [F4.8], [F5.2], [F5.6], [F6.2], [F6.8], [F7.3], [F8.0], [F8.7], [F9.6], [F10], [F11], [CLOSE]. AE SPEED (Exposure - AE speed) Select the adjustment speed for exposure adjustment. You can adjust the speed at which the camera reaches the optimum exposure setting from [1] (standard) to [48] (slow). Adjust this when the brightness of the object changes instantaneously. This setting is available when [MODE] is [FULL AUTO], [SHUTTER Pri], or [IRIS Pri]. EX-COMP (Exposure - Exposure compensation) Turn this [ON] when you want to correct brightness of a picture whose exposure is already automatically adjusted. This setting is available when [MODE] is [FULL AUTO], [SHUTTER Pri], or [IRIS Pri]. The [LEVEL] setting is displayed when this is turned [ON]. LEVEL (Exposure - Exposure compensation) Set a level to adjust the brightness of a picture whose exposure is already automatically adjusted. Choose a value from [-7] to [+7] for the level. This is not displayed when [EX-COMP] is turned [OFF]. GAIN LIMIT (Exposure - Auto gain Max. value) Set the maximum gain when exposure is automatically adjusted using gain. Choose a value from [9dB] to [36dB] (in 3 dB increments). When high-sensitivity mode is set to ON, the available range is expanded from [21dB] to [48dB] (in 3 dB increments). This setting is available when [MODE] is [FULL AUTO], [SHUTTER Pri], or [IRIS Pri]. You cannot choose a value smaller than the [POINT POSITION] setting. GAIN POINT (Exposure - Gain point) When you set [MIN SPEED] to be slower than the output image frame rate, the shutter speed controls exposure based on the [GAIN POINT] setting. Normally, when exposure is controlled with gain, noise becomes prominent if gain is increased to make the image brighter. You can decrease noise by adjusting the exposure with lower shutter speeds after canceling gain adjustments. When you do this, set [GAIN POINT] to [ON] and set the [POINT POSITION] to the gain at which you want the shutter speed to change. When the shutter speed reaches [MIN SPEED] for exposure adjustment, the gain will increase to adjust exposure. This setting is available when [MODE] is either [FULL AUTO] or [IRIS Pri]. POINT POSITION (Exposure - Gain point level) This is enabled when [GAIN POINT] is turned [ON]. When gain during exposure adjustment reaches the value for [POINT POSITION], exposure is adjusted through a slower shutter speed. This setting is available when [MODE] is either [FULL AUTO] or [IRIS Pri]. You cannot choose a value smaller than the [GAIN] setting. MAX SPEED (Exposure - Fastest) Set the maximum (fastest) shutter speed when exposure is automatically adjusted with the electronic shutter. This setting is available when [MODE] is either [FULL AUTO] or [IRIS Pri]. You cannot choose a value slower than [MIN SPEED]. When the signal format is 59.94 or 29.97 You can choose from [1/30], [1/50], [1/60], [1/90], [1/100], [1/125], [1/180], [1/250], [1/350], [1/500], [1/725], [1/1000], [1/1500], [1/2000], [1/3000], [1/4000], [1/6000], [1/10000]. When the signal format is 50 or 25 You can choose from [1/25], [1/30], [1/50], [1/60], [1/100], [1/120], [1/150], [1/215], [1/300], [1/425], [1/600], [1/1000], [1/1250], [1/1750], [1/2500], [1/3500], [1/6000], [1/10000]. 34
