It should be noted that, in this embodiment, the correction blade 200 is of a sheet structure, and in the use process, the thickness of the sheet structure is thinner, and the light-passing hole can be completely blocked in the unfolded state of the correction blade 200, and when the correction blade 200 is in the contracted state, the correction blade 200 can be folded or wound to avoid the light-passing hole, and occupy a smaller space.

Compared with the rotation arrangement mode in the prior art, the correction blade 200 in the embodiment is extensible and contractible, because the correction blade 200 is of a sheet structure, the occupied space is small after contraction, the arrangement of a rotating shaft is avoided, the side wall size of the shell is not required to be lifted for avoiding other parts from affecting the rotating shaft, the space for accommodating the correction blade 200 in the shutter device can be effectively reduced, and the miniaturization of a camera is facilitated; in addition, the straightening vane 200 of the present utility model is extendable and retractable, and replaces the cantilever beam type design of the prior art, so that the problem of interference caused by deformation can be effectively avoided.

In one embodiment, the orthotic blade 200 is extendable and foldable, and the orthotic blade 200 has accordion pleats in the folded state.
