Compulsory Shutter Sound
The shutter sound is generated by the audio during shooting photos. To prevent video voyeurism,
whatever the case, it is forced to sound including when the audio is set to mute and when a set of
earphones is being used.
Flickerless
The CMOS Camera in built-in IT-800 detects flicker automatically and minimizes the affection by
it.
Focus Adjustment
The CMOS digital camera is equipped with a focus adjustment function to enable the operator to
capture focused images. This adjustment comes in the form of a fixed-focus switch and an
autofocus feature. The fixed-focus switch enables the application program to switch the focus to
suit the distance to the object being captured.
The autofocus feature automatically adjusts the focus to suit the distance of the object being
captured. Executing the autofocus function in preview mode automatically adjusts the lens
position to focus the camera. The autofocus adjusts the preview screen s fixed area (focus area) so
that it comes into focus. When the focus area and the focus frame display functions are enabled, a
frame known as the focus frame appears on the preview screen. The focus frame appears green
when the autofocus has been successful. When the autofocus function is not selected or when it is
unsuccessful, the focus frame turns to red. When capturing a still image upon successful autofocus,
the focus frame returns to red.
