1. A camera device comprising:
a fixed unit;
a moving unit comprising:
a board unit disposed so as to be spaced apart from the fixed unit; and
an image sensor disposed on the board unit;
a shape memory alloy member coupled to the fixed unit and the moving unit and conductively connected to the board unit;
a position sensing unit comprising:
a first sensor;
a second sensor; and
a third sensor,
wherein the first sensor, the second sensor, and the third sensor are disposed on the board unit; and
