32 decides the distances between the subject o and the cameras 2 a and 2 b shooting distance s 11 based on the viewing parallax input in s 10 the computing section 32 decides the shooting parallax of the cameras 2 a and 2 b s 12 there are numerous methods to decide the shooting parallax in accordance with the state of the stereoscopic image to be obtained and the shooting environment as shown in embodiments 1 to 3 to be described later the computing section 32 decides the shooting size based on the l size converted value the focal length of the camera 2 a the camera 2 b the desired zoom magnification and the shooting distance decided in s 11 s 13 the computing section 32 subtracts the shooting parallax decided in s 12 from the shooting size decided in s 13 and thus decides the edited size s 14 based on the desired zoom magnification the shooting distance decided in s 11 and the shooting parallax decided in s 12 the person shooting the subject adjusts the positions of the cameras 2 a and 2 b in respect to the subject o then the person shooting the subject synchronizes the cameras 2 a and 2 b and shoots the subject o s 15 the image processing section 33 edits the images of the subject o images a and b obtained by shooting with the cameras 2 a and 2 b based on the edited size decided in s 14 and generates the left and right eye images left eye image l right eye image r s 16 the processing apparatus 3 displays the left and right eye images generated in s 14 on the display section 34 s 17.
