Abstract
A finder apparatus which is used together with a photographing apparatus presents a marker for positioning for setting relative positions of the photographing apparatus and an object for calibration so as to be visually recognizable by an operator in a finder configured to present an image of a subject so as to be visually recognizable by the operator, when photographing the object for calibration including at least one of a known shape and a known surface attribute in order to acquire parameters of a photographing optical system of the photographing apparatus.
Claims25
A finder apparatus which is used together with a photographing apparatus, comprising:
- a finder configured to present an image of a subject so as to be visually recognizable by an operator;
- and
- positioning marker presentation member configured to present at least one marker for positioning for setting relative positions of the photographing apparatus and an object for calibration to the finder so as to be visually recognizable by the operator, when the object for calibration including at least one of a known shape and a known surface attribute is photographed to acquire a parameter of a photographing optical system of the photographing apparatus, wherein said at least one marker corresponds to one of the known shape and the known surface of the object for calibration.
A marker presentation member comprising one of:
- a member through which a visible light is transmitted and on which at least one marker for positioning is partially disposed to set relative positions of a photographing apparatus and an object for calibration including one of a known shape and surface attribute;
- and
- a member including the at least one marker for positioning, wherein
- the one of the member on which the at least one marker for positioning is disposed and the member including the at least one marker for positioning is disposed on an optical path of a light which guides the image of the object for calibration into the operator's eyes, when photographing the object for calibration in order to acquire parameters of a photographing optical system of the photographing apparatus, wherein said at least one marker corresponds to one of the known shape and the known surface of the object for calibration.
A method for presenting a marker for positioning for calibration photography, comprising:
- presenting an image of an object for calibration in a finder which guides the image photographed by a photographing apparatus into operator's eyes so as to be visually recognizable by an operator, when photographing the object for calibration whose one of shape and surface attribute is known in order to acquire parameters of a photographing optical system of the photographing apparatus;
- and
- presenting at least one marker for positioning to set relative positions of the photographing apparatus and the object for calibration in the finder so as to be visually recognizable by the operator, wherein said at least one marker corresponds to one of the known shape and the known surface of the object for calibration.
A finder apparatus which is used together with a photographing apparatus, comprising:
- a finder for presenting an image of a subject so as to be visually recognizable by an operator;
- and
- positioning marker presentation means for presenting at least one marker for positioning for setting relative positions of the photographing apparatus and an object for calibration to the finder so as to be visually recognizable by the operator, when the object for calibration including at least one of a known shape and a known surface attribute is photographed to acquire a parameter of a photographing optical system of the photographing apparatus, wherein said at least one marker corresponds to one of the known shape and the known surface of the object for calibration.
