    • 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.

    • There is described a method as well as a device for motion detect ion in an optical sensing device, such as an optical mouse. A photodetector array comprising a plurality of pixels is used to detect successive light intensity patterns of an illuminated portion of a surface with respect to which a measurement of relative motion is to be determined. Light intensity between neighbouring pixels is compared in order to determine edge direction data descriptive of light intensity differences between the pixels, such data including (i) a first edge condition, or positive edge, defined as a condition wherein light intensity of a first pixel is less than light intensity of a second pixel, and (ii) a second edge condition, or negative edge, defined as a condition wherein light intensity of the first pixel is greater than light intensity of the second pixel. Through comparison of this edge direction data with edge direction data determined from a previous illumination (or by comparing data extracted from this edge direction data) a measurement of the relative motion of the optical sensing device with respect to the illuminated portion of the surface is determined.
