Title:
LENS ASSEMBLY OF IMAGE ACQUISITION DEVICE, AND IMAGE ACQUISITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/279242
Kind Code:
A1
Abstract:
A lens assembly (100, 200, 410) and an image acquisition device (400). The lens assembly (100, 200, 410) comprises a focusing lens (140, 221, 414). The lens assembly (100, 410) further comprises a distance measurement module (110, 411), a drive module (120, 412) and a control module (130, 413), wherein the distance measurement module (110, 411) is used to measure a first distance between the lens assembly (100, 410) and a focus area in a scene; and the control module (130, 413) is used to control the drive module (120, 412) according to the first distance, such that the drive module (120, 412) drives the focusing lens (140, 414) to focus. A focusing system is integrated inside the lens assembly (100, 200, 410), such that the lens assembly (100, 200, 410) can independently complete automatic focusing without depending on cooperation with a body (410) of the image acquisition device (400), thus achieving better compatibility.
