Publication number: 20230011969Abstract: A method of time of flight sensing. The method comprises using an emitter to emit pulses of radiation and using an array of photo-detectors to detect radiation reflected from an object. For a given group of photo-detectors of the array, the method determines based upon measured times of flight of the radiation, whether to use a first mode of operation in which outputs from individual photo-detectors of the group are combined together or to use a second mode of operation in which outputs from individual photo-detectors are processed separately. The array of photo-detectors comprises a plurality of groups of photo-detectors. One or more groups of photo-detectors operate in the first mode whilst in parallel one or more groups of photo-detectors operate in the second mode.Type: ApplicationFiled: December 2, 2020Publication date: January 12, 2023Inventors: Miguel Bruno VAELLO PAÑOS, David STOPPA

Patent number: 11391843Abstract: The current disclosure describes a stereo imaging system that is configured to use Time-of-Flight (“Tof”) techniques to aid in stereoscopic image processing. One process disclosed uses ToF to aid in identifying the same elements (e.g., pixel clusters) in stereo image pairs by narrowing down search areas for matching. Another process uses ToF to aid in identifying the same elements in stereo image pairs where there a small amount texture making it difficult to find a match.Type: GrantFiled: May 14, 2019Date of Patent: July 19, 2022Assignee: ams International AGInventors: Miguel Bruno Vaello Paños, David Stoppa, Markus Rossi, Kang Seok Joo

Publication number: 20220069542Abstract: Illuminator modules having improved safety features are described. In some implementations, light to be emitted from a module is produced by a light source, and light reflected by an optical component disposed over the light source is detected by a photodetectors. A distribution of the reflected light detected by the photodetectors is monitored, and an optical output power of the light source is regulated if it is determined, based on the monitored distribution of light, that an unsafe level of light may be emitted from the module.Type: ApplicationFiled: December 13, 2019Publication date: March 3, 2022Inventors: Miguel Bruno Vaello Paños, David Stoppa, Manfred Lueger, Thomas Jessenig
