Classification: CPC H | IPC H

Claim 0:
1. A sensor apparatus comprising:
a pixel cell configured to generate a voltages, the pixel cell including a photodiode configured to generate charge in response to incoming light, and a charge storage device to convert the charge to a voltage;
an integrated circuit configured to:
determine a first captured voltage converted by the charge storage device during a first time period;
compare the first captured voltage to a threshold voltage value; and
in response to determining that the first captured voltage meets or exceeds the threshold voltage value:
determine first time data corresponding to the first time period; and
prevent the charge storage device from further generating a charge;, and
an analog-to-digital converter (ADC) configured to generate a digital pixel value based on the first captured voltage, and
a memory to store the digital pixel value and the first time data.
