Abstract
A method for controlling a light source of an optical pointing device 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.
Claims20
A method for controlling a light source of an optical pointing device, the method comprising:
- generating quality data representative of a surface quality of an imaging surface being imaged by the optical pointing device;
- and
- controlling the light source based on the generated quality data.
An apparatus for controlling the position of a screen pointer for an electronic device having a display screen, the apparatus comprising:
- a light source for illuminating an imaging surface, thereby generating reflected images;
- and
- an optical motion sensor configured to generate digital images from the reflected images, generate quality data and movement data based on the digital images, the movement data indicative of relative motion between the imaging surface and the apparatus, the quality data indicative of a surface quality of the imaging surface, and wherein the motion sensor is configured to control the light source based on the quality data.
A method of generating movement data with an optical pointing device, the method comprising:
- illuminating an imaging surface with a light source, thereby generating reflected images;
- generating surface quality data indicative of a quality of the imaging surface;
- controlling the light source based on the quality data;
- and
- generating movement data based on the reflected images.
