PROBLEM TO BE SOLVED: To provide a video camera in which an explosion sound arriving later than flowering of fireworks and a flowering image can be recorded and reproduced as the video signal of fireworks, in which the sound and the image are synchronized with each other. SOLUTION: The video camera apparatus comprises: operation setting units 31, 32 for setting the size of an object to be photographed; a zoom ratio detecting unit 33 for detecting zoom magnification of a lens; delay time calculating units 34, 35 for calculating the distance to the object from a relationship between the size of the object set by the operation setting unit and the zoom magnification detected by the zoom ratio detecting unit, and calculating the delay time of audio to be generated in accordance with the distance; an image storage unit 24 for storing an image signal obtained by photographing the object; an image reading unit 25 for reading the stored image signal as a delayed image signal delayed just by the delay time obtained by the delay time calculating units; and a recording unit 27 for recording the audio signal and the delayed image signal on a recording medium.
