Shutter delay
The time it takes for the camera to take the picture, after you have pressed the button from a completely unpressed position (as opposed to a half-pressed position which cuts shutter delay considerably). Subject is 10 metres from the camera.
Image stabilisation
We measure the effectiveness of the camera's image stabiliser by judging pictures taken in trembling motion conditions and low light scenarios.
Low light picture quality
We test the camera's picture quality in challenging low light, judging the amount of graininess and the camera's ability to focus sharply on its subject.
Face detection effectiveness
We test how to see if the camera's face detection can correctly expose and focus on individual faces within a shot. This is a new test added to our 2010 test programme.
Overall picture quality
An overall rating based on our assessment of the camera's picture quality in different light conditions and at different zoom ranges, taking into account sharpness, colour accuracy, contrasting, and any distortions that may be present.
Video quality
An overall rating for the camera's video quality in different light conditions, judging sharpness, smoothness of moving subject and panning shots, and colour accuracy.
Video sound quality
A rating for the recorded sound quality captured by the camera's built-in microphone.
