A shutter apparatus includes a shutter base plate having an opening, a light shielding member movable to provide a closed state for closing the opening and an open state for opening the opening, and at least one processor or circuit configured to perform operations of a control unit configured to control the light shielding member configured to reciprocate relative to the opening so as to move the light shielding member in a first direction for a forward exposure and in a second direction opposite to the first direction for a return exposure. The control unit varies an exposure correction amount of the light shielding member between the forward exposure and the return exposure.

An infrared imaging system is provided with a shutter assembly having an integrated thermistor. In one example, a device includes a shutter assembly. The shutter assembly includes a paddle configured to move between an open position and a closed position. The paddle is configured to block external infrared radiation from reaching a focal plane array (FPA) in a closed position, and pass the external infrared radiation to the FPA in an open position. The shutter assembly also includes an embedded thermistor configured to sense a temperature of the paddle when the paddle is in the open position. In another example, an infrared sensor assembly includes a first set of mechanically engageable electrical contacts for engaging with a second set of mechanically engageable electrical contacts of a shutter assembly electrically coupled with a thermistor through a conductive path. Additional devices and related methods are also provided.

A control apparatus for controlling driving of a focus lens of a lens apparatus includes a memory storing a program and a processor. The processor is configured to execute the program to determine, according to a height of the lens apparatus from a reference position, a focus position of the focus lens indicating a position of the focus lens; and control the driving of the focus lens according to the focus position.

An image capturing apparatus comprises: an image sensor; a light shielding member; a thermometer that measures temperature of the image sensor; and a controller that controls the image sensor so as to perform continuous shooting to obtain a plurality of images. The controller determines a number of images to be shot in the continuous shooting, determines, before starting the continuous shooting, whether or not to shoot a black image with the image sensor being shielded from light by the light shielding member based on the temperature measured by the thermometer and the determined number of images to be shot, and in a case where it is determined to shoot a black image, controls to shoot a black image every time an image is shot in the continuous shooting.

The imaging device includes: an imaging section that includes a plurality of lens units having optical axes aligned in the same direction and one or more imaging elements, the lens units and the imaging elements being combined to form imaging units, the imaging units having different focus temperatures; an image processing unit that calculates a sharpness of an image acquired by each imaging unit; a selection unit that selects an imaging unit which acquires a use image on the basis of the sharpness; and a control unit that controls the imaging section, the image processing unit, and the selection unit.
