摘要： A method for operating an optical sensing device having a light source and a photodetector device with at least one photosensitive element. A surface portion is illuminated with radiation by the light source and the radiation reflected from the illuminated surface portion is detected with a photosensitive element. While said surface portion is being illuminated, an output signal of the photosensitive element over time is integrated, the output signal integration level is compared with a first integration reference level during integration; the integration step is interrupted if the output signal integration level has reached the first integration reference level, or the comparison step is repeated until a first integration period has elapsed if the output signal integration level has not reached the first integration reference level.

摘要： A method for detecting a lift condition from an illuminated surface portion of an optical motion sensing device. According to a first embodiment, two different “loss-of-focus” thresholds are used. A first threshold is used when the optical pointing device is not moving, and a second threshold greater than the first one is used when the optical pointing device is moving. The optical device further requires means for detecting whether it is moving or not. According to a second embodiment, a dynamical loss-of-focus threshold depending on an average number of motion features that the surface exhibits to the sensor of the optical pointing device is used.

摘要： There is described an optical sensing device, a method for controlling operation of an optical sensing device comprising a light source for illuminating a surface portion with radiation, a photodetector device having at least one photosensitive element responsive to radiation reflected from the illuminated surface portion, and conversion means for integrating an output signal of said at least one photosensitive element over time during an integration period of variable duration, which duration depends on power of the light source and level of radiation reflected from the illuminated surface portion. The optical sensing device further comprises a regulating system for controlling power if the light source as a function of a comparison between a parameter representative of the evolution of the integration of the output signal of the said at least one photosensitive element and at least one reference value. Regulation is advantageously performed by timing the duration of the integration period or by determining the rate of evolution of the integrated signal, comparing this duration or rate of evolution with at least one reference value and controlling power of the light source as a function of the result of the comparison. There is also described an optical pointing device implementing the above regulation scheme as well as an optical sensing device exploiting this scheme so as to sense proximity of the illuminated surface portion with respect to the optical sensing device.
