Abstract
A camera and method are disclosed which provide a photographer with a picture composition guide that may be viewed through the viewfinder. Standard composition points corresponding to golden section points are displayed for the photographer to see. LCD's or LED's are used to display the composition points, and an external display portion allows the photographer to check a display state of the standard composition points.
Claims18
A camera, comprising:
- an internal main light path having a first end and a second end;
- an object lens located at the first end of the main light path for receiving and transmitting light from a subject, thereby forming a subject image;
- a main mirror located in the main light path for receiving and reflecting the subject image;
- a penta-prism located in the main light path for receiving the subject image reflected by the main mirror and for further twice reflecting the subject image to form an upright real image of the subject;
- an eye lens located at the second end of the main light path, and oriented in a manner permitting a user to view the upright real image;
- a photosensitive portion located outside of the main light path on a side of the mirror opposite the main light path, the photosensitive portion being arranged to receive the subject image when the subject image is permitted to pass beyond the main mirror;
- and
- a display device having a rectangular display surface located in the main light path, the display surface having a central composition point C.sub.0 located at a central junction of diagonals of the display surface, and four surrounding composition points C.sub.1, C.sub.2, C.sub.3, and C.sub.4 located at junctions between said diagonals and four lines, each line passing through one corner point of the rectangular display surface, and each line being perpendicular to one of the diagonals.
A method of displaying on a display portion of a display device of a camera standard composition points for enabling a user to adjust picture composition, the display device including a driving portion for applying power supply to said portion, and a mode selection portion for controlling a display of said standard composition points between an initial state and a user selected state, the method comprising the steps of:
- selecting a display state of said standard composition points;
- displaying on said display portion said standard composition points corresponding to said selected state;
- photographing a subject;
- and
- resetting the display state of said standard composition points to the initial state,
- wherein said step of resetting includes the substeps of:
- checking whether film is exhausted;
- automatically rewinding the film and canceling the display state of said standard composition points if the film is exhausted;
- checking whether the selection of the display state of said standard composition points differs from the initial state when the film is not exhausted;
- and
- resetting the display portion to the initial state when the film is not exhausted.
A method of displaying standard composition points on a display portion of a display device in a camera, the composition points for providing a picture composition guide to a user, the display device including a driving portion for applying power to said display portion, a mode selection portion for controlling a display of said standard composition points between an initial state and a user selected state, and an external display for indicating a display state of said standard composition points in accordance with signals transmitted thereto from said mode selection portion, the method comprising the steps of:
- selecting a display state of said standard composition points;
- displaying on said display portion said standard composition points corresponding to said selected state;
- displaying a representation of said standard composition points of said selected state on said external display;
- photographing a subject;
- and
- resetting the display state to said initial state.
