Information processing apparatus, information processing method, and storage medium

An information processing apparatus comprising:

• one or more memories storing instructions;
• and
• one or more processors executing the instructions to:
• acquire input information about an input corresponding to an operation on an operation member for changing a first position parameter indicating a position of a virtual camera on a first axis and a second position parameter indicating a position of the virtual camera on a second axis, the virtual camera corresponding to a virtual viewpoint image generated based on a plurality of captured images acquired by image-capturing a subject by a plurality of image capturing apparatuses;
• execute first adjustment processing for adjusting an amount of change of the first position parameter when an amount of the operation is maximum;
• execute second adjustment processing for adjusting the amount of change of the first position parameter and the second position parameter when the amount of the operation is maximum;
• and
• execute third adjustment processing for adjusting the amount of change of the first position parameter and the second position parameter with respect to the amount of the operation.

An information processing method comprising:

• acquiring, as a first acquisition, input information about an input corresponding to an operation on an operation member for changing a first position parameter indicating a position of a virtual camera on a first axis and a second position parameter indicating a position of the virtual camera on a second axis, the virtual camera corresponding to a virtual viewpoint image generated based on a plurality of captured images acquired by image-capturing a subject by a plurality of image capturing apparatuses;
• acquiring, as a second acquisition, a first adjustment parameter for adjusting an amount of change of the first position parameter when an amount of the operation is maximum;
• acquiring, as a third acquisition, a second adjustment parameter for adjusting the amount of change of the first position parameter and the second position parameter when the amount of the operation is maximum;
• acquiring, as a fourth acquisition, a third adjustment parameter for adjusting the amount of change of the first position parameter and the second position parameter with respect to the amount of the operation;
• and
• deciding on the amount of change of the first position parameter and the second position parameter based on the input information, the first adjustment parameter, the second adjustment parameter, and the third adjustment parameter.
