  • Patent number: 11277580
    Abstract: A time-of-flight device comprises a pixel array including a plurality of pixel circuits arranged in an array, respective ones of the plurality of pixel circuits including a first photodiode configured to selectively output two analog signals respectively via two paths, and including a second photodiode configured to selectively output two analog signals respectively via two paths; a signal line coupled to the first photodiode and a second photodiode; and processing circuitry including: a comparator configured to compare a voltage of the signal line with a reference signal and to output a comparison result, and a counter configured to perform a count based on the comparison result in response to a count control signal, wherein the count control signal is configured to switch the counter between an up count mode and a down count mode while a count value is held in the counter.

  • Patent number: 10904456
    Abstract: A time-of-flight image sensor (TOF) for imaging with ambient light subtraction. In one embodiment, the TOF image sensor includes a pixel array, a control circuit, and a signal processing circuit. The signal processing circuit reads out a first data signal from respective first floating diffusions and respective second floating diffusions during a first frame while a light generator is not emitting, reads out a second data signal from the respective first floating diffusions and the respective second floating diffusions during a second frame after the first integration and after a second integration while the light generator is emitting, generate a third data signal indicative of ambient light, generate a fourth data signal indicative of the ambient light and a light signal reflected off an object, and generate a fifth data signal indicative of the light signal by subtracting the third data signal from the fourth data signal.

  • Patent number: 9215386
    Abstract: A pixel readout circuit for use with an imaging pixel array, comprising: an input channel for receiving an image signal corresponding to an electrical output of a photosensitive element of the pixel; and an electronic circuit interconnected between an input channel and an output readout utility. The electronic circuit comprises a capacitive unit, and a single analyzer. The capacitive unit is controllably linked to the input channel for accumulating a charge corresponding to received intensity generated by the pixel during a single frame period, and is connected to the output readout utility.

The capacitive unit is controllably linked to input channel for accumulating charge corresponding to received intensity generated by said pixel during a single frame period, and is connected to output readout utility. The signal analyzer unit is controllably linked to input channel and connected to output readout utility, and is configured for analyzing at least a part of said image signal by determining change in amount of accumulated charge corresponding to the received intensity, and upon detecting that the amount of charge satisfies a predetermined condition generating data indicative of a detected event.
