US 12,356,091 B2 · Methods for transmitting asynchronous event data via synchronous communications interfaces using anticipated event rates, and associated imaging systems

Abstract

Methods for transmitting asynchronous event data via synchronous communications interfaces (and associated imaging systems) are disclosed herein. In one embodiment, an imager comprises an array of event vision pixels, and a synchronous communications transmitter configured to transmit frames of data to a synchronous communications receiver. The pixels generate event data based on activity within an external scene. The imager communicates, at a first time and to the receiver, an anticipated amount of data that will be included in a frame transmitted to the receiver at a second time. The anticipated amount of data can be based on a prediction of an amount of event data that will be generated at a future point in time for transmission to the receiver in the frame. The imager can then transmit the frame to the receiver at the second time with an amount of data corresponding to the anticipated amount of data.

Dependent claims

An imager, comprising:

an array of event vision pixels, each pixel of the array configured to generate event data based at least in part on events indicated in incident light received from an external scene;
and
a synchronous communications transmitter configured to transmit frames of data to a synchronous communications receiver,
wherein the imager is configured to:
communicate, at a first time and to the receiver, an anticipated amount of event data that will be included in a frame transmitted from the transmitter to the receiver at a second time occurring after the first time, and
transmitting the frame to the receiver at the second time, wherein the frame includes an amount of data corresponding to the anticipated amount of event data.

3 more elements

An imaging system, comprising:

a synchronous communications receiver;
and
an imager including a synchronous communications transmitter (a) operably connected to the synchronous communications receiver via a synchronous communications interface and (b) configured to transmit frames of data to the synchronous communications receiver via the synchronous communications interface, the imager further including an array of event vision pixels, each pixel of the array configured to generate event data based at least in part on events indicated in incident light received from an external scene,
wherein the imager is configured to:
communicate, prior to transmission of a frame of data from the transmitter to the receiver, an indication of an anticipated amount of data that will be included in the frame when the frame is transmitted to the receiver at a future point in time;
and
after communicating the indication of the anticipated amount of data, transmit the frame to the receiver, wherein the frame includes an amount of data corresponding to the anticipated amount of data, and
wherein, to accommodate receiving the frame with the amount of data corresponding to the anticipated amount of data, the receiver is configured to adjust its local receiver circuit prior to receiving the frame from the transmitter.
