Title:
IMAGING DEVICE AND VEHICLE-MOUNTED SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/249743
Kind Code:
A1
Abstract:
[Problem] To make it possible for a small imaging device to easily reduce variations in focus caused by temperature changes. [Solution] This imaging device has: a lens barrel that holds a plurality of lenses 104a, 104b; an imaging element 115 that images an object through the plurality of lenses; and a holding member 105 that holds the imaging element and the lens barrel. The lens barrel is configured by combining a plurality of partial lens barrels 101, 102 that respectively hold the lenses. The holding member holds any one among the plurality of partial lens barrels in a holding section 108 further toward the object side than the lens, closest to an image side, among the plurality of lenses. The linear expansion coefficient of at least one partial lens barrel among the plurality of partial lens barrels is different from the linear expansion coefficients of the other partial lens barrels.
