The input information acquiring unit (22) of an information processing device (14) receives an instruction input from the user. An image capturing condition control unit (24) allows capturing of images to be started under an image capturing condition determined on the basis of the user's instruction or the analysis result of a captured image. An image capturing condition storage unit (26) stores an image capturing condition table in which intended functions are made correspond to image capturing conditions. A first image analysis unit (32) and a second image analysis unit (34) acquire respective images captured by a first camera (28) and a second camera (30) both mounted on an imaging device (12) and perform necessary image analyses. An image integration unit (36) integrates the images captured by the pair of cameras and the analysis results. An image data generation unit (38) generates image data to be output as a processing result.
