As shown in FIG. 1B and FIG. 3B, in the embodiment, when the driving component 130 drives the light-shielding member FN to expose the light-shielding member FN to the lens LN and the image sensing component 100 (ie, the image capturing device 10 is turned on) The viewing via hole VH of the shield frame BF may expose the temperature sensing element 120B. At the same time, the shielding frame BF can also selectively block the humidity sensing component 120A. The user can know the temperature state inside the lens module 110 through the temperature sensing component 120B during startup, thereby avoiding overheating. The image capturing device 10 is used for a long time under the environment to cause damage.

It should be noted that the case where the temperature sensing element 120B is exposed and the humidity sensing element 120A is completely shielded is illustrated in FIG. 3B as an example.

The lens barrel 140 surrounds the lens LN and coats the lens LN in common with the shield frame BF and the light blocking member FN. The lens barrel 140 has an extension portion EP extending toward the inside of the lens module 110. The extension EP is against the lens LN. The extension portion EP may also selectively have a second permeable through hole EH that communicates with the space in which the lens LN is located. The second permeable through hole EH has a similar effect to the first permeable through hole AH described above, which can transmit the temperature or humidity of the lens LN on the lens module 110 between the extension portion EP and the lens LN. The medium reacts to the environment sensing component 120, and the environmental sensing component 120 can more accurately reflect the actual condition of the humidity or temperature inside the lens module 110.

Referring to FIG. 1A again, in the embodiment, the lens module 110 of the image capturing device 10 may further include a decorative sheet DP. The shielding frame BF is disposed between the environment sensing element 120 and the decorative sheet DP.
