1. An image capturing module, comprising:
a light filter, comprising a light receiving surface and a light emitting surface opposite to each other;
a meta-lens layer, disposed side by side with the light filter, wherein the meta-lens layer comprises a light transmitting film and a plurality of microstructures, and the plurality of microstructures are arranged on the light transmitting film; and
a photosensitive element, comprising a photosensitive surface, the photosensitive surface faces to the meta-lens layer and the light emitting surface of the light filter, wherein
the plurality of pixels comprise a visible light sensing pixel and an infrared light sensing pixel;
the photosensitive surface has a plurality of pixels, the plurality of pixels respectively correspond to the plurality of microstructures;
the plurality of microstructures of the meta-lens layer comprise a first microstructure and a second microstructure, the first microstructure corresponds to the visible light sensing pixel, the second microstructure corresponds to the infrared light sensing pixel, and the first microstructure is different from the second microstructure; and
when an external light enters the light transmitting film of the meta-lens layer, the external light focuses on the visible light sensing pixel through the first microstructure and focuses on the infrared light sensing pixel through the second microstructure.
