Abstract

The invention provides a digital processing method for a negative film, and a terminal. The digital processing method for the negative film comprises the steps of shooting the negative film via a camera to acquire a first image; performing reversal processing on the first image to acquire a second image; and adjusting color gradation of a plurality of color channels of the second image to acquirea digital image corresponding to the negative film. According to the method provided by the invention, the camera of the terminal is used for shooting the negative film, the shot images are processed,and thus digitization of the negative film is achieved, operation is quick and convenient, and expensive devices, complex parts and special operation are not needed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a digital processing method and a terminal for negative films. Background technique [0002] Today, with the popularization of digital cameras, many users still use film to take photos, especially negative films. In the traditional method, the photographed film is developed with chemicals. After fixing, the negative needs to be digitized by a professional negative scanner or a transparent scanner, and it can only be displayed on the screen after cropping, reverse, color mask removal, and dust removal. See a picture with normal colors. [0003] In addition, if you do not use a scanner to digitize the negatives, you need a professional viewer equipped with cold cathode fluorescent lamps to illuminate the negatives evenly from behind, and use a digital camera with a macro lens to retake the photos, and then copy the initial photos digitized in this way on the computer Aft...
