FIELD: optical apparatuses.
SUBSTANCE: invention relates to optical apparatuses, i.e. to objective apparatuses and cameras used in camera systems with a function of image blur correction. The proposed camera (100) used in a camera system includes a camera including an image sensor (104) configured to move to correct image blur, and an objective apparatus (101) detachably attached to the camera and including an optical element (113) configured to move to correct image blur. The camera therein comprises: an installation unit (102) configured to set, in each blur direction from multiple blur directions, the ratio of the blur correction values provided by movements of the optical element and the blur correction values provided by movements of the image sensor, wherein the multiple blur directions differ from each other relative to the sign of the direction, using information about the image circle formed by the objective apparatus, the information about the value of mechanical movement of the image sensor, and the information about the size of the signal reading area of the image sensor.
EFFECT: technical result is creation of a camera and an objective apparatus, wherein each of the described is capable of efficiently using the value of movement of the image sensor even when the centre of the image circle is displaced from the centre of the image sensor.
