1. An information processing apparatus, comprising: a central processing unit (CPU) and a memory storing instructions that cause the CPU to: estimate a posture of a human figure extracted from a captured image of a subject, wherein the human figure comprises a human region that comprises body segments extracted from the captured image, wherein the posture is estimated based on coordinates of a plurality of joints that connect the body segments of the human figure; and set a shutter speed for image capture based on a comparison of the coordinates of the plurality of joints in a first frame with the coordinates of the plurality of joints in a second frame, wherein the coordinates are calculated in a three-dimensional space.
