Claim:
1. A method of image conversion operation for panorama dynamic IP (Internet Protocol) camera, a dynamic image captured by three wide-angle cameras panoramically and received by a PC(Personal Computer)/smartphone/tablet via Internet is divided equally into an upper block, a middle block and a bottom block, when a browser frame of the PC/smartphone/tablet is moved by a user by sliding a touchscreen of the PC/smartphone/tablet for reading a desired dynamic image, the method comprises steps as below: (a) if the browser frame is moved along the middle block, the dynamic image covered by the browser frame is displayed on the touchscreen of the PC/smartphone/tablet directly; (b) if the browser frame is moved along the upper block or the bottom block, a horizontal length of the upper block or the bottom block is w, for any point (x, y) in the browser frame, a radius r and an angle θ are calculated from the coordinates x and y as below:  a pixel corresponding to the point (r, θ) has a distance r away from an upper edge of the upper block or an bottom edge of the bottom block, and has a distance w* (θ/360) away from a left edge of the upper block or the bottom block; the pixel is filled to the point (x, y) in the browser frame; in the same way, each point in the browser frame can be filled by a pixel in the upper block or the bottom block so that a real top dynamic image or a bottom dynamic image captured by the three wide-angle cameras is displayed in the browser frame without distortion.
