Description

The present invention deals with the field of image processing technology, and particularly relates to an auxiliary device for image reading.

Image processing is a technology for converting the properties of a wide range of images such as photographs and figures. Nowadays, in many cases, images are digitized and put into a computer, and the shading of the image is changed to make it easier for humans to see (image enhancement), image blurring and noise are removed (image restoration), and images are used. The focus is on removing the spatial distortion of the image, changing its size, and rotating it (geometric transformation of the image). Two-dimensional Fourier transform and filtering are also one of the basic technologies. Feature extraction in pattern recognition, such as extracting lines from an image or extracting certain areas, may also be discussed in image processing. In recent years, image processing technology has been widely applied in fields such as aviation, military, biomedicine, and artificial intelligence.
In image processing, devices that digitize photographs and figures are also important, except for specific conversion methods. When sampling an image, the brightness of each sampled pixel may differ from the actual brightness due to the influence of the surrounding environment. Further, the existing hand-held image scanner is unstable due to hand-held at the time of sampling, and the read data is deviated.
