US 2025/0159367 A1 · METHODS FOR OPERATING HYBRID IMAGE SENSORS HAVING DIFFERENT CIS-TO-EVS RESOLUTIONS

Abstract

Methods for operating hybrid image sensors having different CIS-to-EVS resolutions (and associated systems, devices, and methods) are disclosed herein. In one embodiment, an imaging system includes a hybrid image sensor including (a) an event driven sensing array including one or more event vision sensor (EVS) pixels arranged in one or more EVS pixel rows and configured to capture EVS data having an EVS resolution, and (b) a pixel array including a plurality of CMOS image sensor (CIS) pixels arranged in one or more CIS pixel rows and configured to capture CIS data having a CIS resolution. The imaging system can further include control circuitry configured to adjust the CIS resolution of the CIS data and/or the EVS resolution of the EVS data such that a mismatch between the CIS resolution and the EVS resolution is reduced.

Dependent claims

A method of operating an imaging system including a hybrid image sensor, the method comprising:

adjusting a first resolution associated with CMOS image sensor (CIS) pixel data captured using a plurality of CIS pixels of the hybrid image sensor, wherein adjusting the first resolution includes adjusting the first resolution to reduce a mismatch between the first resolution and a second resolution associated with event vision sensor (EVS) pixel data captured using one or more EVS pixels of the hybrid image sensor, and wherein the one or more EVS pixels correspond to the plurality of CIS pixels;
or
adjusting the second resolution, wherein adjusting the second resolution includes adjusting the second resolution to reduce the mismatch between the first resolution and the second resolution.

An imaging system, comprising:

a hybrid image sensor including—
an event driven sensing array including one or more event vision sensor (EVS) pixels arranged in one or more EVS pixel rows, wherein each EVS pixel of the one or more EVS pixels is configured to capture EVS data corresponding to contrast information of light incident on that EVS pixel, and wherein EVS data captured using the one or more EVS pixels of the event driven sensing array has an EVS resolution, and
a pixel array including a plurality of CMOS image sensor (CIS) pixels arranged in one or more CIS pixel rows, wherein each CIS pixel of the plurality of CIS pixels is configured to capture CIS data corresponding to intensity of light incident on the CIS pixel, and wherein CIS data captured using the plurality of CIS pixels of the pixel array has a CIS resolution;
and
control circuitry configured to adjust the CIS resolution of the CIS data and/or the EVS resolution of the EVS data such that a mismatch between the CIS resolution and the EVS resolution is reduced.
