Abstract:
1. A long-range optical device having at least one tube, in which an optical system is positioned, having at least one image stabilization unit, which is designed for the purpose of moving at least one optical assembly of the optical system relative to the at least one tube, having at least one signal processing unit which is designed such that it actuates the at least one image stabilization unit in one mode of a plurality of modes, wherein a respective movement situation of the long-range optical device is assigned to each mode, and having a mode detection unit which is designed such that it determines the mode from the plurality of modes, wherein the mode detection unit is furthermore designed such that it determines the mode in that it ascertains at least one comparative value from a respective location derivative value of a trajectory formed from a first movement and a second movement of the long-range optical device and compares the at least one comparative value to a respective limiting value and wherein the respective location derivative value is a location derivative of the trajectory at a discrete point in time, or that the respective location derivative value is an integral of a location derivative of the trajectory over a third period of time and wherein the location derivative is a first derivative of the trajectory with respect to the first movement or with respect to the second movement and/or that the location derivative is a second derivative of the trajectory with respect to the first movement or the second movement and wherein the location derivative is the smaller in absolute value of the first derivatives of the trajectory with respect to the first movement and the second movement and/or that the location derivative is the smaller in absolute value of the second derivatives of the trajectory with respect to the first movement and the second movement.
