摘要： An optical filter for a camera is switchable between a reflection state and a transmission state. The optical filter includes a first plurality of liquid crystals configured to dynamically form cholesteric phase structures in the reflection state that block right-handed circularly polarized light in a spectral light sub-band and transmit light outside of the spectral light sub-band. The first plurality of liquid crystals dynamically forms a nematic phase arrangement in the transmission state that transmits light in the spectral light sub-band. The optical filter further includes a second plurality of liquid crystals configured to dynamically form cholesteric phase structures in the reflection state that block left-handed circularly polarized light in the spectral light sub-band and transmit light outside of the spectral light sub-band. The second plurality of liquid crystals dynamically form a nematic phase arrangement in the transmission state that transmits light in the spectral light sub-band.

摘要： The invention relates to a method for correcting a distortion in an aerial photograph caused by a flight movement in the forward direction. The aerial photograph is captured by a surface sensor, the sensor lines of which sensor are exposed at different, successive exposure times, so that each individual sensor line senses a strip of terrain of the terrain flow over at the different exposure times. A relative flight altitude above the strips of terrain captured by the respective sensor line is assigned to the individual sensor lines. Furthermore, a compensation factor is separately determined for each of the individual sensor lines, wherein the factor depends on an air speed of the flying object, a focal length of the aerial camera and the relative flight altitude assigned to the respective sensor line, and corrects the distortion in the aerial photograph for the lines based on the respective compensation factor.

摘要： After a shutter drive motor drives a shutter to a holding mode, if a first determination unit determines that a mirror is not ready to move to a mirror up mode, a control unit switches the shutter drive motor to a first braking mode. After the shutter drive motor is switched to the first braking mode, if the first determination unit determines that a mirror is ready to move to the mirror up mode before a second determination unit determines that the shutter drive motor is to be switched to a second braking mode, the control unit switches the shutter drive motor to an open mode until a predetermined period of time has elapsed since the first determination unit determined that the mirror was ready to move to a mirror up mode.

摘要： When the lens barrel is in the storage state, a part of a lens group and a group cylinder are inserted into an aperture of a diaphragm unit and a shutter blade of a shutter unit is closed for light shielding. With this arrangement, the cylinder length in the storage state is shortened, and the performance degradation of an image sensor and optical components provided on a front side of an image sensor can be prevented as well.
