There is provided a monitoring camera apparatus which, while ensuring waterproofness, can perform focus adjustment when a dome cover is mounted. A lens () is covered by the dome cover () which is removable. A focus adjustment mechanism () moves an imaging device () in an optical axis direction and thereby performs focus adjustment. A setting button () being a focus setting operation unit is arranged in the inner side of the dome cover (), and operated when the dome cover () is mounted. A controller () controls the focus adjustment mechanism (). The controller () allows the focus adjustment mechanism () to start focus adjustment when a predetermined focus start wait time has elapsed after operation of the setting button (). The focus start wait time is set according to a standard mounting operation time required to mount the dome cover ().

The invention provides a range finder capable of carrying out three-dimensional measurement stably for a long period of time. A light pattern is projected on a subject by using a light source array unit in which a plurality of light sources, such as LEDs, are arranged. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. Also, a plurality of light patterns can be generated by electrically controlling a light emitting state of each LED of the light source array unit.
