Document Type and Number:
WIPO Patent Application WO/2024/078032
Kind Code:
A1
Abstract:
The present application relates to the technical field of image processing, and discloses a signal processing method and apparatus, a device, a storage medium, and a computer program. The method comprises: acquiring an image signal and a first event signal of a target scene, wherein the first event signal is an event signal in a frame format or a stream format; performing temporal-dimension and/or spatial-dimension format conversion on the first event signal to obtain a second event signal, wherein the second event signal is an event signal in a frame format; and fusing the second event signal and the image signal to obtain a fused signal. The image signal indicates brightness information of a plurality of pixels within an exposure time, and the event signal indicates motion information of the plurality of pixels within the exposure time. Therefore, the fused signal obtained by fusing the event signal and the image signal not only comprises the brightness information of the plurality of pixels, but also comprises the motion information of the plurality of pixels. In this way, the quality of an image can be improved by means of a dense fused signal having both brightness information and motion information.
