Abstract
Methods and systems for recognizing a film in a scanner are provided. First, the film is previewed by the scanner to obtain an original preview image. 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.

An automatic film recognition method for recognizing a film in a scanner, comprising the steps of:
- (a) previewing the film using the scanner to obtain an original preview image comprising a film image corresponding to the film, wherein the original preview image comprises pixels and each pixel has a first hue value, a second hue value, and a third hue value;
- (b) selecting the pixels with luminance in a predetermined range from the original preview image to acquire a second preview image;
- (c) framing the second preview image according to the first hue values of the pixels to obtain an image frame;
- and
- (d) sectioning the image frame to recognize the film image.
A machine-readable storage medium for storing, a computer program providing an automatic film recognition method for recognizing a film in a scanner, the method comprising the steps of:
- (a) previewing the film using the scanner to obtain an original preview image comprising a film image corresponding to the film, wherein the original preview image comprises a plurality of pixels and each pixel has a first hue value, a second hue value, and a third hue value;
- (b) selecting the pixels with luminance in a predetermined range from the original preview image to acquire a second preview image;
- (c) framing the second preview image according to the first hue values of the pixels to obtain an image frame;
- and
- (d) sectioning the image frame to recognize the film image.
An automatic film recognition apparatus for recognizing a film in a scanner, comprising:
- an image previewing module, previewing the film using the scanner to obtain an original preview image comprising a film image corresponding to the film, wherein the original preview image comprises a plurality of pixels and each pixel has a first hue value, a second hue value, and a third hue value;
- an image processing module, coupled to the image preview module, selecting the pixels with luminance in a predetermined range from the original preview image to acquire a second preview image;
- an image framing module, coupled to the image processing module, framing the second preview image according to the first hue values of the pixels to obtain an image frame;
- and
- a film recognition module, coupled to the image framing module, sectioning the image frame to recognize the film image.
