Abstract
A method (500) of providing a picture composition guide on a display device (407) of a camera (450) is disclosed. The method (500) operates by firstly detecting (502) settings of the camera (450). Image analysis (503) is then performed on an image being displayed on the display device (407), the image representing a photographic scene. Next, the presence and location of strong features are determined based on the result of the image analysis (503). One or more markers are selected (505) dependent upon the camera settings and the strong features. The one or more markers are then superimposed over the image on the display device (407).
Claims4
A method of providing a picture composition guide on a display device of a camera, said picture composition guide being useful for assisting a user to capture a sequence of panoramic photographs with said camera, said method comprising the steps of:
- detecting a panorama mode of said camera;
- detecting an orientation of said camera;
- performing image analysis on an image being displayed on said display device, said image representing a photographic scene;
- detecting the location of a horizon in said image;
- selecting a first horizontal line marker dependent upon the location of said horizon when the orientation of said camera is a first orientation, and a second horizontal line marker dependent upon the location of said horizon when the orientation of said camera is a second orientation;
- superimposing the first or second horizontal line marker over said Image on said display device;
- and
- retaining the first or second horizontal line marker after the capture of a first image, the retained first or second horizontal line marker being useful for assisting said user to capture subsequent images in said sequence of panoramic photographs.
A camera providing a picture composition guide on a display device of said camera, said picture composition guide being useful for assisting a user to capture a sequence of panoramic photographs with said camera, said camera comprising:
- means for detecting a “panorama mode” of said camera;
- means for detecting an orientation of said camera;
- means for performing image analysis on an image being displayed on said display device, said image representing a photographic scene;
- means for detecting the location of a horizon in said image;
- means for selecting a first horizontal line marker dependent upon the location of said horizon when the orientation of said camera is a first orientation, and a second horizontal line marker dependent upon the location of said horizon when the orientation of said camera is a second orientation;
- means for superimposing the first or second horizontal line marker over said image on said display device;
- and
- means for retaining the first or second horizontal line marker after the capture of a first image, the first or second horizontal line marker being useful for assisting said user to capture subsequent images in said sequence of panoramic photographs.
