摘要： In an image pickup device, a crystal as an optical low pass filter is rotatable in a vertical plane that is vertical to an optical axis. In a normal mode and a shift mode, the crystal is rotated in order to change a separation direction of pixels. Thereby, moirés in a circular zone can be eliminated in the normal mode, and moirés in a high frequency side can be eliminated in the shift mode while a contrast zero line is not passed through the center section of the circular zone in order to prevent the decreasing of a resolution and to improve the characteristic of the shift mode. Because the rotary mechanism can be formed simply and smaller, the device can be manufactured with a low coast and a high realibility.

摘要： A light intensity control device includes a fixed opening 261, an aperture stop part 26 for controlling a light flux of incident light, a light intensity aperture part 24 for changing the size of an opening by moving a plurality of aperture blades to limit a light intensity of transmitted light and a ND filter 25 having a transparent area 253 and a light blocking area 254, which is arranged to be movable between a first light blocking state where the transparent area 253 faces the fixed opening 261 of the aperture stop part 26 and a second light blocking state where the light blocking area 254 faces the fixed opening. The moving of the ND filter 25 is carried out when the opening area of the light intensity aperture part 24 is a maximum.

摘要： An imaging device includes a matrix array of photosensor pixels. An effective area in the array is set to a first region during a first mode of operation of the imaging device, and is set to a second region during a second mode of operation of the imaging device. The first and second regions are different in number of photosensor pixels contained therein. A holder retains the array. The holder is moved between a first position at which an optical axis related to light incident to the array coincides with a center of the first region and a second position at which the optical axis coincides with a center of the second region. The holder is fixed at the first position during the first mode of operation of the imaging device, and is fixed at the second position during the second mode of operation of the imaging device.
