Camera Notes：
The camera's autofocus function may not perform as expected in the following circumstances.
 The subject is very dark.
 The subject lacks contrast (e.g. the sky, a white wall, etc.) or there is little contrast between
the subject and the surroundings (e.g. the subject is standing in front of a white wall while
wearing a white shirt).
 Objects of sharply differing brightness are included in the scene (e.g. the sun is behind the
subject and the subject is in deep shadow).
 The subject is a flat object with only horizontal lines.
 The subject is a fast-moving object.
 The scene is poorly lit.
 The scene features bright reflections or backlighting.
 The scene features flickering objects (e.g. fluorescent lights).
 The scene features point light sources (e.g. light bulbs, spotlights, or LEDs).
 The scene features several objects that are different distances from the camera.
In these circumstances where the camera is unable to focus, point the camera at another object
at the same distance as the camera as the subject, then wait for the camera to focus and take
the picture.
