Image capturing and stabilization apparatus and method capable of performing image stabilization control by moving an image sensor

An image capturing apparatus to which a lens apparatus is attached, comprising:

• an image sensor that performs photoelectric conversion on a subject image formed by the lens apparatus and outputs an image signal;
• a driving unit that drives the image sensor according to a driving amount for compensating shake;
• and
• an image stabilization apparatus comprising:
• a calculation unit that calculates the driving amount;
• an image stabilization control unit that controls image stabilization by controlling the driving unit based on the driving amount calculated by the calculation unit;
• a determination unit that determines whether a current state of the image stabilization apparatus is a first state or a second state according to an image shooting state;
• and
• a control unit that controls a center position of image stabilization control based on an acquired center position of an image circle of the lens apparatus,
• wherein the control unit is configured to, responsive to the acquired center position of the image circle of the lens apparatus shifting from a first lens position to a second lens position, set an initial center shift position and a shiftable range of the image stabilization control at:
• (i) a first sensor position which is a first distance from the second lens position when the image stabilization apparatus is in the first state, and (ii) a second sensor position which is a second distance from the second lens position when the image stabilization apparatus is in the second state, wherein the first distance is larger than the second distance,
• wherein each unit is implemented by one or more processors, circuitry or a combination thereof.

An image stabilization method comprising:

• calculating a driving amount for moving an image sensor so as to compensate for shake;
• controlling image stabilization by moving the image sensor based on the driving amount calculated by the calculation unit;
• determining whether a current state is a first state or a second state according to an image shooting state;
• and
• controlling a center position of image stabilization control based on an acquired center position of an image circle of a lens apparatus attached to an image capturing apparatus having the image sensor,
• wherein control of the center position of the image stabilization control includes, responsive to the acquired center position of the image circle of the lens apparatus shifting from a first lens position to a second lens position, setting an initial center shift position and a shiftable range of the image stabilization control at:
• (i) a first sensor position which is a first distance from the second lens position when the image stabilization apparatus is in the first state, and (ii) a second sensor position which is a second distance from the second lens position when the image capturing apparatus is in the second state, wherein the first distance is larger than the second distance.

A non-transitory computer-readable storage medium, the storage medium storing a program that is executable by the computer, wherein the program includes program code for causing the computer to function as an image stabilization apparatus comprising:

• a calculation unit that calculates a driving amount for moving an image sensor so as to compensate for shake;
• an image stabilization control unit that controls image stabilization by moving the image sensor based on the driving amount calculated by the calculation unit;
• a determination unit that determines whether a current state of the image stabilization apparatus is a first state or a second state according to an image shooting state;
• and
• a control unit that controls a center position of image stabilization control based on an acquired center position of an image circle of a lens apparatus attached to an image capturing apparatus having the image sensor,
• wherein the control unit is configured to, responsive to the acquired center position of the image circle of the lens apparatus shifting from a first lens position to a second lens position, set an initial center shift position and a shiftable range of the image stabilization control at:
• (i) a first sensor position which is a first distance from the second lens position when the image stabilization apparatus is in the first state, and (ii) a second sensor position which is a second distance from the second lens position when the image stabilization apparatus is in the second state, wherein the first distance is larger than the second distance.
