Claim 19:
20. A system for determining at least one geometrico-morphological parameter of a subject in a natural posture to determine a vision correction equipment, the system comprising:
a visual target configured to be placed in front of the subject, such that the subject is placed in a natural posture when at least one gaze direction of the subject points to said visual target;
an image capture apparatus configured to be placed between the head of the subject and said visual target, on a line linking one of the eyes of the subject and the visual target, the image capture apparatus being configured to capture an image of the head of the subject, the image capture apparatus including a pupil;
an adjustment system configured to adjust one or more of a position and an orientation of the image capture apparatus in order for the pupil of the image capture apparatus to be positioned close to the gaze direction of at least one of the eyes of the subject; and
a calculator configured to deduce the at least one geometrico-morphological parameter from said image of the head of the subject captured with said image capture apparatus.
