The invention relates generally to edge detection and presentation in thermal images. Infrared and visible light images comprising at least partially overlapping target scenes are analyzed. An edge detection process is performed on the visible light image to determine which pixels represent edges in the target scene. A display image is generated in which some pixels include infrared image data and in which pixels corresponding to edges in the visible light image include a predetermined color and do not include corresponding infrared image data to emphasize edges. Edge pixels in the display image can include exclusively the predetermined color, or in some examples, a blend of a predetermined color and visible light image data. Methods can include replacing one or the other of visible light edge pixels or corresponding infrared pixels with the predetermined color before combining the visible light and infrared image data to create a display image.

A photographing device according to the present invention comprises: an imaging section that captures a subject image and outputs image data; a motion picture recording section that records a motion picture based on the image data; a parameter setting section that sets a photographing parameter to change a photographing state; and a parameter control section that automatically changes the photographing parameter during the recording of the motion picture regardless of the set photographing parameter.

A method and an apparatus for retrieving information for managing video data involving link information associating metadata with the video data. A metadata indicator is used to indicate that metadata exists in a stream with the linking information. Link information also associates the metadata with location information to identify where additional information on the video data, which is described by the metadata, may be found. Using the method or apparatus, a single metadata unit is able to be associated with a plurality of video data units, or a plurality of metadata units are able to be associated with a single video data unit, in order to provide more information on the video data.
