Problems solved by technology
If the user sets the negative or positive scanning mode incorrectly when operating the scanning device, the scanning device will not be able to properly process the image generated by the scanned negative or positive film, resulting in abnormal colors of the image
[0004] To sum up, the scanning device has played an increasingly important role in image processing, and the scanning device in the prior art can also be used to convert negative and positive films into digital images, but because the scanning device needs to use different adjustment parameters to Handle negative and positive digital images, so users need to switch between negative and positive scanning modes
However, most users have little experience in operating scanning devices, and users need to switch scanning modes according to the objects to be scanned, which is quite inconvenient for users

Embodiment Construction
[0044] see figure 1 , figure 1 It is a functional block diagram of the scanning device of the present invention. The scanning device 100 includes a tray interface 110 , a detection module 120 , a scanning module 130 , an image processing module 140 and an output module 150 . The tray interface 110 can connect the first tray 111 and the second tray 112 . Negative films and positive films must be placed on different types of trays due to their different shapes, and then read by the scanning device 100 through the tray interface 110. The first tray 111 is used to carry the first type of object is a negative film, and the second tray 112 is used to carry The second type of object is a positive film, and the two types of trays cannot be used interchangeably. Therefore, the scanning device 100 of the present invention can automatically switch the image processing mode according to the identification element set on the tray. When the negative is placed on the first tray 111 and c...

The invention discloses a scanning device, which comprises a first tray, a second tray, a detecting module, a scanning module and an image processing module. The first tray is provided with an identification element. When the scanning module scans the first tray, the detecting module detects that the identification element generates a first signal; and when the scanning module scans the second tray, the detecting module does not detect that the identification element generates a second signal. When the image processing module receives the first signal, a scanned image is processed by a first set of parameters; and when the image processing module receives the second signal, the scanned image is processed by a second set of parameters.
Description
technical field [0001] The invention relates to a scanning device, especially a scanning device capable of automatically switching image processing modes. Background technique [0002] With the development of digital technology, image data has gradually evolved into a digital storage method. Scanning devices can convert not only photographs into digital images, but also negatives (negatives) and positives (transparencies) into digital images. However, due to the different shapes of the negative film and the positive film, the user needs to use the negative film tray to carry the negative film, and the positive film tray to carry the positive film. The negative film tray and the positive film tray cannot be used interchangeably. Then, the negative film tray or the positive film tray is connected to the scanning device, and the negative film or the positive film can be scanned by the scanning device. [0003] In addition, after the negative film and the positive film are sca...
