Abstract: A distance sensing apparatus includes a light source configured to emit polarized light. A light sensitive detector detects light emitted by said light source and reflected from a target. The light sensitive detector is configured to substantially prevent polarized light reflected from a target with a relatively high reflectance from being detected.

Abstract: A sensing apparatus includes a sensor and a processor. The sensor includes at least one light sensitive detector. The processor determines a first control value to control a voltage differential across the at least one light sensitive detector, and compares the first control value with a reference value associated with a reference temperature. Based on the comparison, the processor provides adjustment information for adjusting at least one output of the sensing apparatus, and an operating parameter of the sensing apparatus other than the voltage differential.

Abstract: A method includes receiving a histogram output from a detector sensor, and calculating a median point of a pulse waveform within the histogram. The pulse waveform has an even probability distribution over at least one quantization step of the histogram around the median point. A corresponding apparatus can include a detector sensor and a co-processor coupled to the detector sensor.

Abstract: An electronic device includes a ranging light source and a reflected light detector. A logic circuit causes the ranging light source to emit ranging light at a target. Reflected light from the target is detected using the reflected light detector, with the reflected light being a portion of the ranging light that reflects from the target back toward the reflected light detector. An intensity of the reflected light is determined using the reflected light detector. A distance to the target is determined based upon time elapsed between activating the ranging light source and detecting the reflected ranging light. Reflectance of the target is calculated, based upon the intensity of the reflected light and the distance to the target.

Abstract: An autofocus method determines that a ranging device of a digital camera has failed in an attempt to provide a distance estimation. The ranging device provides one or more parameters indicating conditions related to the failure of the ranging device to provide the distance estimation. An autofocus sequence based on the one or more parameters is then performed.

Abstract: A range detector device may include a pulsed light source configured to emit pulsed light to an object, a detector configured to receive reflected pulsed light from the object, and a processor cooperating with the pulsed light source and the detector. The processor may be configured to generate a measured range value to the object, and generate an estimated statistical value for a spread of possible range values based upon a characteristic of the pulsed light source.
