An image sensor comprises a plurality of pixels. Pixels are capable of detecting a change in an amount of light intensity and pixels are capable of detecting an amount of light intensity. In a first mode the sensor outputs data from the first one or more of the pixels. In a second mode the sensor outputs data from the second one or more of the pixels. The first mode may be a lower power operation mode and the second mode may be a higher power operation mode. At least one of the first mode and the second mode is selected by a processor based on at least one of a result of processing data output in the first mode and a result of processing data output in the second mode.

Methods and systems of low power facial recognition

An imaging device with a plurality of image sensing pixels and a plurality of event detection pixels is provided. The image sensing and event detection pixels can be provided as part of different arrays of pixels, or can be included within a common array of pixels. The event detection pixels are operated continuously to provide signals indicating the occurrence of events. In response to detecting an event, image sensing pixels are selectively operated. The selective operation of the image sensing pixels can include activation of image sensing pixels within one or more regions of interest, while image sensing pixels not included in any region of interest remain off. The selective operation of the image sensing pixels can include the selection of a frame rate applied across an array of mage sensing pixels, or within determined regions of interest.

Dynamic region of interest and frame rate for event based sensor and imaging camera

An imaging device includes a pixel, and a signal processor configured to randomly apply a first set of signals including a first driving signal applied to a first light source, and a first set of control signals applied to the pixel that adhere to a quasi-Gray code scheme to generate first through eighth correlation signals based on light output from the first light source according to the first driving signal and reflected from an object. The signal processor is configured to randomly apply a second set of signals including a second driving signal applied to the first light source, and a second set of control signals applied to the pixel that adhere to the quasi-Gray code scheme to generate ninth through sixteenth correlation signals based on light output from the first light source according to the second driving signal and reflected from the object.

Imaging devices and multiple camera interference rejection

An imaging device includes a pixel and a signal processor configured to apply a first set of control signals to the pixel to generate a first pixel signal, a second pixel signal, a third pixel signal, and a fourth pixel signal based on light reflected from an object. The signal processor is configured to apply a second set of control signals to the pixel to generate a fifth pixel signal, a sixth pixel signal, a seventh pixel signal, and an eighth pixel signal based on the light reflected from the object. The signal processor is configured to calculate a distance to the object based on comparisons between selected ones of the first, second, third, fourth, fifth, sixth, seventh, and eighth pixel signals.

Imaging devices and decoding methods thereof for determining distances to objects

A device has a plurality of analog-to-digital converters. Each of the plurality of analog-to-digital converters has a voltage offset, wherein a predefined set of voltage offsets has a voltage offset distribution pattern, which provides a fingerprint for the device.
