[Exposure] [Manual] [Shutter Speed Limit (Lower)] [Shutter Speed Limit (Upper)] - - * You cannot select a speed lower than [Shutter Speed Limit (Lower)]. [Shutter Speed] 1/1 - 1/16000 (sec.) Important • If a traffic signal, electronic scoreboard, etc. is captured the video may flicker. In this case, try changing [Exposure] to [Auto (Shutterpriority AE)] and then select a shutter speed lower than 1/100 seconds so that the condition improves. • Setting a slow shutter speed may prevent the intelligent function from working correctly. Select a shutter speed that suits the capture conditions and purpose. [Aperture] If [Auto (Aperture-priority AE)] or [Manual] is selected for [Exposure], set a desired aperture. Moving the slider to the left closes the aperture and darkens the image. Moving the slider to the right opens the aperture and brightens the image. [Gain] If [Manual] is selected for [Exposure], set the sensitivity to affect brightness. Moving the slider to the left darkens the video, and moving it to the right brightens video. [Exposure Compensation] When [Exposure] is set other than [Manual], you can adjust the brightness of the video by selecting the [Exposure Compensation]. Important The setting is not available if [Smart Shade Control] is set to [Auto]. [Metering Mode] When [Exposure] is set a value other than [Manual], you can selects a metering mode. [Center-Weighted] Performs photometry with the entire screen center-weighted. Even if there is a slight difference in light and dark around the screen, subjects near the center will have the appropriate exposure. Use this when the subject is near the center of the screen. [Average] Performs photometry with the average of the entire screen. This enables stable exposure to be obtained even in environments with large differences in light and dark on the screen. Use this to stabilize the exposure for scenes when cars are passing or people are entering and exiting. [Spot] Performs photometry with the center of the screen. This enables the appropriate exposure to be obtained for subjects in the center of the screen, regardless of differences in light and dark around the screen. Use this to match the exposure with the center of the screen when the subject is hit by spotlights or backlit. [Smart Shade Control] If the background is bright and the subject is hard to see, this function brightens dark areas without affecting bright areas to make the subject easier to see. This is different from Backlight Compensation (P. 71). This function suppresses over-exposure of highlights while compensating for under-exposure in dark areas of the video. Important • [Auto] cannot be selected for [Smart Shade Control] if [Exposure] is set to [Manual]. • [Smart Shade Control] is not available if [Haze Compensation] is set to [Auto] or [Manual]. [Manual] Set the level of compensation in [Smart Shade Control Level]. 116
