Outline

The following operation allows the alignment of the shutter speed of the camera with the variable scanning rate of a computer monitor or display.

When a computer monitor screen or display is shot with the camera, a bright horizontal line indicating excessive exposure is displayed in cases when the scanning rate of the monitor is faster than the shutter speed of the camera. A dark horizontal line indicating insufficient exposure is displayed in cases when the monitor’s scanning rate is slower than the camera’s shutter speed.

The scanning frequency of a monitor varies due to various reasons during the computer operation. Adjust the scanning rate to obtain a stable image while observing the image in the viewfinder or LCD monitor.

Variable Scan [V.SCAN]
