Abstract
A portable electronic device, and an image-capturing device and an assembly method thereof are provided. The image-capturing device includes a carrier substrate, an image sensing chip, a filter element and a lens assembly. The carrier substrate has a through opening and a recessed space. The image sensing chip is disposed on the bottom side of the carrier substrate. The filter element is disposed in the recessed space of the carrier substrate, so that all or a part of the filter element is accommodated in the through opening. When at least one microparticle with a maximum particle size between 5 μm and 25 μm is located on the filter element, a shortest distance between the filter element and the image sensing chip is between 30 μm and 200 μm, so that the image sensing chip cannot capture a light spot generated due to blocking of the microparticle.
