20130335576 | DYNAMIC ADAPTATION OF IMAGING PARAMETERS - Representative implementations of devices and techniques provide adaptable settings for imaging devices and systems. Operating modes may be defined based on whether an object is detected within a preselected area. One or more parameters of emitted electromagnetic radiation may be dynamically adjusted based on the present operating mode. | 12-19-2013 |
20140139631 | DYNAMIC CONSERVATION OF IMAGING POWER - Representative implementations of devices and techniques provide adaptable settings for imaging devices and systems. Operating modes may be defined based on whether movement is detected within a predetermined area. One or more parameters of illumination or modulation may be dynamically adjusted based on the present operating mode. | 05-22-2014 |
20140145686 | CHARGE CONSERVATION IN PIXELS - Representative implementations of devices and techniques provide conservation of charge in a pixel. Charge in the pixel may be alternately stored in a first gate capacitance of the pixel and a second gate capacitance of the pixel. Transferring the charge between the gate capacitances conserves some or all of the charge, and reduces input power used to charge the gate capacitances. | 05-29-2014 |
20140312233 | TIME OF FLIGHT ILLUMINATION CIRCUIT - Some aspects of the present disclosure provide system and method of operation of a driving circuit for a light emitting element in a Time-of-Flight (ToF) camera. A DC-DC converter is configured to emit a constant current, and is coupled in parallel to a first modulation switch configured to connect the driving circuit to ground. The first modulation switch is further configured to alternate connections between the current source and ground at a frequency in a desired range of operation to produce an AC current. In some embodiments, an RC circuit element is coupled to an output electrode of the light emitting element and configured to apply a reverse bias to decrease turn-off time of the light emitting element. In some embodiments, a second modulation switch is coupled to the output electrode and configured to apply the reverse bias across the light emitting element. Other systems and methods are also disclosed. | 10-23-2014 |
20150049168 | DYNAMIC ADJUSTMENT OF IMAGING PARAMETERS - Representative implementations of devices and techniques provide adjustable parameters for imaging devices and systems. Dynamic adjustments to one or more parameters of an imaging component may be performed based on changes to the relative velocity of the imaging component or to the proximity of an object to the imaging component. | 02-19-2015 |
20150077542 | ADAPTIVE DISTANCE ESTIMATION - Representative implementations of devices and techniques provide adaptive distance estimation for imaging devices and systems. Distance estimation may be based on phase delays in reflected light. Reference phases used to determine phase delay values may be changed for subsequent frame events. Multiple frame events may be selected for some distance calculations based on whether object movement is detected within a predetermined area. | 03-19-2015 |
20150138371 | INTEGRATED REFERENCE PIXEL - Representative implementations of devices and techniques provide dynamic calibration for imaging devices and systems. A reference pixel is arranged to receive an electrical reference signal and to output a calibration signal. The reference signal may be based on imaging illumination. | 05-21-2015 |
20150356747 | TIME-OF-FLIGHT CAMERA WITH LOCATION SENSOR SYSTEM - A time-of-flight (TOF) camera system includes a radiation source, a radiation detector, a location sensor system and a processor. The radiation source is configured to generate and emit a radiation that strikes a target object. The radiation detector is configured to detect the radiation reflected from the target object and generate a sample set comprising at least two raw samples detected in succession at different times based on the reflected radiation. The location sensor system is configured to detect movements of the TOF camera during the detection and generate a movement signal having portions thereof uniquely corresponding to each of the raw samples of the sample set based on the movements of the TOF camera, wherein a portion of the movement signal is detected at a same time of generating the corresponding raw sample. The processor is configured to receive the raw samples and the corresponding movement signal portions and generate an object information based on the raw samples and the corresponding movement signal portion. | 12-10-2015 |
