The starting point SP includes an integer part sp_in and a fractional part sP-frac. Since the panel is of the shutter type, the image signal in the current image frame is the left eye image number, and the image signal in the next image is the right eye image signal. That is, 'the shutter type panel' left eye/right eye image 5 tigers are interlaced in different images. Therefore, as shown in Fig. 6, the starting points 4.1, 3.3, ... corresponding to the pixel lines 1, 2, ... of the current image plane are decremented, and the pixel lines 1 and 2 corresponding to the next image plane are displayed.
