Abstract
A photographing device includes a camera mounting unit on which a camera is detachably mounted, a light source unit arranged at a predetermined distance from the camera mounting unit, and a table which is arranged between the light source unit and the camera mounting unit, and on which an object is placed. The object placed on the table is illuminated by the light source unit, and can be photographed by the camera.
Claims23
A photographing device comprising:
- a camera mounting unit on which a camera is detachably mounted and having a receiving portion which covers a portion of said camera on which a lens unit is provided, said camera mounting unit having operation buttons corresponding to operation buttons of said camera;
- a light source unit arranged to be separated from said camera mounting unit by a predetermined distance;
- and
- a table which is arranged between said light source unit and said camera mounting unit, and on which an object is placed,
- wherein when said camera is mounted on said camera mounting unit, an operation of said camera using said operation buttons of said camera is inhibited, and the object placed on said table is illuminated by said light source unit and can be photographed by an operation using said operation buttons of said camera mounting unit.
A photographing device for photographing an object while a photographing unit is held at short range from the object, comprising:
- an object placing unit for holding the object within a photographing region of said photographing unit;
- support means for supporting said photographing unit at a predetermined short range from said object placing unit;
- shield means, arranged around the photographing region, for shielding external light incident on the photographing region;
- and
- an observation window for viewing the object held by said object placing unit from outside of said shielding means, said observation window being formed in a portion of said shielding means.
A photographing device for photographing an object while a photographing unit is held at short range from the object, comprising:
- an object placing unit for holding the object within a photographing region of said photographing unit;
- holding means having an exterior portion for holding said photographing unit at predetermined short range from said object placing unit, and shielding external light incident on the photographing region;
- and
- an observation window for viewing the object held by said object placing unit from outside of said shielding means, said observation window being formed in said exterior portion of said holding means.
A photographing device comprising:
- an object placing unit for placing an object;
- photographing means, held at predetermined short range from said object placing unit, for photographing the object, said photographing means including a photographing lens optical system;
- illumination means for illuminating the object placed on said object placing unit;
- diffusing means for diffusing light emitted from said illuminating means;
- and
- correction means for correcting a luminance distribution of an object image incident on said photographing means, wherein said correction means has luminance distribution characteristics for correcting a decrease in circumferential light amount caused by said photographing lens optical system.
A photographing device for photographing an object while a photographing unit is held at short range from the object, comprising:
- an object placing unit for holding the object within a photographing region of said photographing unit;
- support means for supporting said photographing unit at predetermined short range from said object placing unit;
- and
- photometric light guiding means, arranged between photometric means of said photographing unit and the object, for guiding a light amount on the photographing region to said photometric means of said photographing unit.
A photographing device for photographing an object while a photographing unit is held at a short range to the object, said device comprising:
- a photographing unit including photometric means;
- an object placing unit for holding the object within a photographing region of said photographing unit;
- support means for supporting said photographing unit at a predetermined short range from said object placing unit;
- and
- photometric correction means, arranged between said photometric means of said photographing unit and the object, for correcting an intensity distribution of light incident on said photometric means from the photographing region of said photographing unit.
A photographing device for photographing a film placed at predetermined short range, comprising:
- a film placing unit for holding the film within a photographing region;
- film guide means for allowing the film to be able to be inserted from two orthogonal directions on said film placing unit;
- and
- aligning means consisting of a plurality of pressing portions for aligning the film by pressing the film brought into said film placing unit by said film guide means against said film placing unit,
- wherein said pressing portions press the film at a plurality of positions located outside of the photographing region and along a diagonal line that divides the photographing region.
