The original preview image comprises a film image corresponding to the film. The original preview image also comprises pixels and each pixel has a first hue value, a second hue value, and a third hue value. The pixels with luminance in a predetermined range are then selected from the original preview image to acquire a second preview image. Next, the second preview image is framed according to the first hue values of the pixels to obtain an image frame. Finally, the image frame is sectioned to recognize the film image.
