Shutter Control
It is sometimes desirable to reduce the time during which the
sensor gathers light (called “exposure time”, “integration time” or
“shutter time”) in order to reduce motion blur and “freeze” the
motion in each frame. The default shutter time is equal to the frame
time, but this may be reduced by this control. The shutter time is
measured as the ratio between frame time and shutter time, e.g.
x10 means that the shutter is open for 1/10 of the frame period. The
shutter period may range from the frame period (x1) to 1/200 of the
frame period (x200), but is subject to a 5 microsecond lower limit
and a 1 second upper limit.
The user should note that as the shutter ratio is increased, the
camera will require more light.
`
WB Set Control
This control activates the automatic white balance function. Before
pressing this control, the user must place a pure white reference
(sheet of paper etc.) if front of the camera, completely filling the field
of view. This must not be removed until the white balance is
complete. An on screen message shows the status of the white
balance process.
Please refer to Chapter 8 “Understanding the Olympus i--SPEED 2 ”
for a further description.
The control is only available if the white balance mode is set to
automatic.
NOTE
Once this is set, the white balance setting is stored in
the camera’s internal memory.
