<p>A method for controlling a light source of an optical pointing device (e.g. a mouse) includes generating quality data representative of a surface quality of an imaging surface being imaged by the optical pointing device. The method includes controlling the light source based on the generated quality data. Apparatus for controlling the position of a screen pointer comprises a light source 118 for illuminating an imaging surface 124, thereby generating reflected images, and an optical motion sensor 114, 112 configured to generate digital images from the reflected images, and to generate quality data and movement data based on the digital images, the movement data being indicative of relative motion between the imaging surface and the apparatus, and the quality data being indicative of a surface quality of the imaging surfaces. The motion sensor is configured to control the output of the light source based on the quality data.</p> |
