The projector system of the present disclosure has a projector, a mirror, an angle detector, and a calculator. The projector projects an image. The mirror tilts each of on intersecting two axes as an axis of rotation and reflects the image projected from the projector. The angle detector detects an inclination angle of the mirror. Based on the inclination angle, the calculator calculates a reflection-possible range of the mirror, a projection-possible range of the projector that corresponds to the reflection-possible range, and an image range so that the image is arranged within the projection-possible range.

A shake measurement system () is an apparatus for measuring the amount of shake of a camera (), and comprises a first shake amount acquisition section, a second shake amount acquisition section, and a third shake amount acquisition section. The first shake amount acquisition section uses image processing to acquire the amount of shake of the camera () as a first shake amount. The second shake amount acquisition section acquires the amount of shake of the camera () as a second shake amount by a different method from that of the first shake amount acquisition section. The third shake amount acquisition section acquires the amount of translational shake of the camera () on the basis of the first shake amount and the second shake amount.

A lens barrel includes a lens frame, a guide shaft, a lead screw, a nut, and a biasing spring. The guide shaft is inserted into the lens frame. The nut is threaded onto the lead screw. The biasing member biases the lens frame toward the nut. The lens frame includes a first bearing component having a first insertion hole and a second bearing component having a second insertion hole. The guide shaft hits an inner peripheral face of the first insertion hole at a first and second contact point, and hits an inner peripheral face of the second insertion hole at a third and fourth contact point. The first and second contact points are disposed on opposing side of the third and fourth contact points using as a reference a parallel plane which extends along the direction of an optical axis and passes through a guide axis.

An imaging device capable of detecting and correcting, with high accuracy, the motion (image rotation) in the rolling direction of the image caused by the camera shake during imaging without being influenced by the individual variation, temperature characteristic, and variation with time of the sensor. To correct the motion (image rotation) in the rolling direction of the image caused by the camera shake during imaging, the result of detection of the angle of inclination of the device by an angle sensor () is corrected with the result of detection of the angle of inclination of the image on the basis of the feature of the captured image by an image inclination detecting section (), and the imaging device () is rotated around the optical axis or an axis parallel to the optical axis according to the corrected angle of inclination of the device.
