A control apparatus provided in a lens apparatus controls a plurality of optical systems each including an aperture diaphragm which is variable in aperture diameter. A lens control unit sets driving amount information regarding the respective driving amounts of the aperture diaphragms, and sets driving speed of each of the aperture diaphragms based on the driving amount information. The lens control unit determines the driving speeds of the respective aperture diaphragms such that driving times of the aperture diaphragms of the plurality of optical systems match each other.

An actuator mechanism is provided for disposing a plurality of filters into and out of a camera line-of-sight. The mechanism includes a base, a pair of frames, an axial shaft, a plurality of filter housings and a plurality of pivotable drivers. The base includes an auxiliary platform. The frames flank the base, and the shaft is disposed between the frames. Each filter housing holds a corresponding optical filter and is disposable in a deployment position in the line-of-sight and a withdrawn position out of the line-of-sight. The drivers are disposed on the platform. Each driver corresponds to an associated housing and is rotatable along the shaft to swing at least one housing between deployment and withdrawn positions upon command.

An aperture device for setting an amount of light incident on a lens of a camera module is provided. The aperture device includes: a diaphragm plate exhibiting a plate shape and formed with an aperture opening penetrating the diaphragm plate in a plate surface direction; and a configuration-changing mechanism for changing a configuration of the diaphragm plate to an aperture position or a retracted position, where the aperture position is a position where the diaphragm plate is on the lens and a center of the aperture opening is configured in a position corresponding to an optical axis of the lens, and the retracted position is a position where the diaphragm plate is retracted from the lens.

The invention relates to a field of capturing images requiring a long exposure, e.g., when photographing faint objects. The device comprises an image formation unit, an image capture unit, a primary shutter and a secondary shutter connected to at least one disturbance detector via a control unit.

Provided are a blur detection device, an imaging device, a lens device, an imaging device main body, a blur detection method, and a blur detection program capable of appropriately detecting blurring of an imaging device. An angular velocity of a digital camera and a posture of the digital camera with respect to an Earth's rotation axis are detected. An Earth's rotation angular velocity component superimposed on a detection result of the angular velocity is calculated. The Earth's rotation angular velocity component is subtracted from the detection result of the angular velocity, and a blur amount of the digital camera is calculated based on the subtracted angular velocity.

The present invention makes it possible to suppress, to the greatest extent possible, a situation where, in an image capturing apparatus that captures images automatically, the apparatus misses capturing a video that a user wishes to capture. An image capturing apparatus comprises an image capturing unit for capturing an object image and outputting image data, a control unit for controlling whether or not to carry out an image capturing operation of recording the image data output by the image capturing unit, and an obtaining unit for obtaining information pertaining to a frequency of the image capturing operation, wherein the control unit changes a threshold for determining whether or not to carry out the image capturing operation in accordance with the information pertaining to the frequency and total image capturing time.

An example method includes recording dark images on an image sensor on-board an orbital vehicle during flight, which include a first image recorded before the orbital vehicle is over a predefined location on the Earth and a second image recorded after the orbital vehicle is over the predefined location; and recording third and fourth images on the image sensor during flight based on illumination from a light source that is on-board, with the third image being recorded before the orbital vehicle is over the predefined location and the fourth image being recorded after the orbital vehicle is over the predefined location. A fifth image is recorded on the image sensor during flight while the predefined location on the Earth is visible to the image sensor. The fifth image is based on light from a ground-based calibration system. The light source is calibrated during flight based on the five images.
