Image acquisition and output method

Abstract

The invention relates to an image acquisition and output method. The method comprises the following steps: providing an image acquisition device; continuously acquiring a plurality of row images fromthe initial position and recording position information corresponding to each row image; calculating the difference between the position information of the first row image and the initial position andthe difference between the position information of each of the rest row images and the position information of the previous row image to obtain filling information; Filling each row of image into theimage buffer according to the filling information; And directly outputting the image buffer as a finished image. Therefore, the technical effects of effectively solving the image deformation problem,saving the memory space, reducing the manufacturing cost and the like can be achieved.

Description

technical field [0001] The disclosure relates to an image acquisition method, in particular to an image acquisition and output method that can reduce image distortion and save memory. Background technique [0002] Handheld image capture devices, such as handheld scanners, are often used as image capture tools for document digitization in recent years. Since it is held by the user and captures the image of the document in one direction, it will inevitably be skewed during operation, and at the same time, there are many restrictions on the operation because it can only be moved in one direction. [0003] In response to the above situation, the industry has developed several existing image acquisition and output methods for skewed images. For example, see Figure 1A and Figure 1B ,in Figure 1A is a schematic diagram showing the temporary buffer acquired by existing image acquisition and output methods, and Figure 1B It is a schematic diagram showing the output buffer to b...
