Samsung patents camera chip that fixes timing errors in fast video

Samsung describes a camera sensor that detects changes in light and records the exact time each change happens. If the sensor detects a glitch or abnormal reading, the device uses the timing of nearby correct readings to estimate and fix the wrong time stamp.

Why it mattersThis technology could help cameras capture clearer images in fast-moving scenes by correcting small timing mistakes that might otherwise cause blurring or distortion.

In the filing’s own words

An image processing device includes a vision sensor and a processor. The vision sensor generates a plurality of events in which an intensity of light changes and generates a plurality of timestamps depending on times when the events occur. In addition, the processor may regenerate a timestamp of a pixel where an abnormal event occurs, based on temporal correlation of the events.

What exactly they claim (claim 1)

1. A dynamic vision sensor comprising: a plurality of photodiodes including a first photodiode of a first pixel; an amplifier configured to amplify a voltage level corresponding to charges generated by the first photodiode; a comparator configured to determine a type of an event based on the voltage level of the charges and output an on-event or an off-event; a first address event representation configured to generate a first address of the first pixel; a second address event representation configured to generate a second address of the first pixel; and a packetizer configured to generate a packet, the packet including a timestamp of the first pixel, the first address of the first pixel and the second address of the first pixel, wherein the amplifier and the comparator are disposed in a first semiconductor chip, wherein the first and second address event representation are disposed in a second semiconductor chip, and wherein the first semiconductor chip is stacked on the second semiconductor chip.
