DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic diagram of a main part for explaining an embodiment of a video photographing apparatus and a photographing method supporting apparatus according to the present invention. In FIG. A photographed image 12 photographed by the video photographing apparatus is photographing information such as a shutter speed, an aperture value, a focusing distance, and a lens focal length. The photographed image 11 and the photographing information 12 are photographed. Sometimes recorded. 10
In the figure, reference numeral 11 denotes a photographed image and photographing information, 13 denotes a photographed image / photographing information management module, 14 denotes a trouble phenomenon instruction module, 15 denotes a trouble cause inference module, and 16 denotes trouble solving. A method presentation module, 17 is a failure cause inference knowledge base, and 18 is a failure solution method inference knowledge base. The present invention now provides
It is assumed that the content description for multimedia video information has been implemented by MPEG-7 or the like, which has been standardized by SO / IEC / SC29WG11.
It has already been proposed in Japanese Patent Application No. 0-249526 and Japanese Patent Application No. 10-249527.

According to the present invention, a defective photographing portion is inferred in accordance with the following operation procedure based on the photographing information by using the video information and the content description information attached thereto. [Operation Procedure] The print designation is performed in the following procedure. a) Shoot an object to be shot. b) The following information at the time of shooting is recorded according to the video content description system. Printing specification items-Focusing distance-Aperture value-Shutter speed-Luminance sensor luminance sensitivity value-Lens focal length c) The photographing result and photographing information are input to the photographing method support device. d) Point out a defect phenomenon in the photographing result. e) Infer the cause of the defect based on the photographing information. f) Present a processing method for improving the defect.

Next, a description will be given of a process of inferring a fault and a method of coping with the fault. [Defect Inference] In the defect inference, the following knowledge base model is created in advance from the defect in the photographing result. <Defects> Phenomenon 1 The subject is too dark or underexposed Cause: High aperture value, fast shutter speed Phenomenon 2 The subject is too bright, overexposed Cause: Low aperture value, slow shutter speed Phenomenon 3 Blurry, camera shake Cause: Slow shutter speed Mismatched focus Cause: Incorrect focus position

[Troubleshooting method support] A countermeasures method for solving the above-mentioned cause is registered in advance, and a measure corresponding to the cause is presented. <Countermeasures> Phenomenon 1 The aperture value and shutter speed that can be reduced based on the brightness sensor value are presented. Phenomenon 2 The aperture value and shutter speed that can be raised based on the brightness sensor value are presented. Phenomenon 3 The shutter speed that can be raised based on the brightness sensor value is presented.

[0014]

According to the first aspect of the present invention, when a video is shot, the shooting status can be grasped by recording the shooting information.

According to the second aspect of the present invention, by simultaneously managing the photographed video and the photographing information, it is possible to infer the cause of the trouble of the photographing result from the photographing information.

According to the third aspect of the present invention, it is possible to infer a trouble phenomenon of the photographing from the photographing information, to provide guidance for improvement, camera operation, and setting, and to support a user's photographing technique. .

According to the fourth aspect of the present invention, the photographing state can be managed together with the image by managing the relationship between the photographed image and the photographing information.

According to the fifth aspect of the present invention, a knowledge base for inferring a defect that can be inferred from photographing information is prepared, and a knowledge base for presenting a response method based on the phenomenon of the defect and the photographing information is prepared. The cause and the solution can be presented.

According to the invention of claim 6, according to claims 3 to 5
Can be processed as a program on a computer.
