Cases not suited for face matching
The performance of the face matching function varies depending on such conditions as the camera installation, camera settings,
camera adjustment, surroundings and photographic subjects. Therefore, face matching may not be performed in the following
cases.
• Illuminance levels are dispersed. (Example: Outdoors)
• Faces are interrupted by such objects as medical masks, sunglasses or helmets.
• Faces are not directed to the front side.
• Photographic subjects are moving quickly.
• Strong light sources (such as the headlights of a car, rising sunlight or setting sunlight) may affect the shooting place from
outside.
To improve the performance of face matching
• Register the target face images from the images recorded by the camera installed under the same conditions.
• Perform settings for the camera so that the camera can shoot face images at a balanced illuminance level both in the day-
time and nighttime.
• Install the camera so that the camera can move within the assumed moving pathway of photogenic subjects.
• If people's faces are printed on a poster, perform the setting for "Setup area" (
☞
page 61) so that these faces are not target-
ed for face matching.
