Operating Basics

Using TOSHIBA Face Recognition

This feature uses a face verification library to verify the face data of users

when they log in Windows. The user can thus avoid having to enter a

password or the like, which makes the login process easier.

■ Do not point the web camera directly at the sun.

■ Do not touch or press strongly on the web camera lens. Doing so may

reduce image quality. Use an eyeglass cleaner (cleaner cloth) or other

soft cloth to clean the lens if it becomes dirty.

■ Setting the [Size] to more than "800 × 600" will cause a larger amount

of data to be written to the hard disk drive and may interfere with

smooth recording.

■ When recording in dimly lit environments, the following procedure can

be used to select "Night Mode" which allows for brighter images with

less noise.

1. Click the Properties button on the [Web Camera] menu.

2. Check Night Mode on the [Options] tab.

3. Click the OK button.

The number of frames per second is lowered when "video recording" in

"Night Mode". This may result in the playback of the recorded video file

seeming unsmooth.

■ TOSHIBA Face Recognition does not guarantee the correct

identification of a user. Changes to the likeness of a registrant, such as

hairstyle changes, wearing a cap, or wearing glasses may affect the

recognition rates when such changes occur after the registrant had

registered.

■ TOSHIBA Face Recognition may incorrectly recognize faces that are

similar to a registrant.

■ For high security purposes, TOSHIBA Face Recognition is not a

suitable substitute for Windows passwords. When security is a high

priority, use your established Windows passwords to log in.

■ Bright background light and/or shadows may prevent a registrant from

being recognized correctly. In that case, log in using your Windows

password. If recognition of a registrant fails repeatedly, refer to your

computer documentation to learn ways to improve recognition

performance.

■ TOSHIBA Face Recognition records face data in a log when face

recognition fails. When transferring ownership or disposing of your

computer, please uninstall the application or delete all the logs created

by the application. For details on how to do this, see help file.
