Embodiment Construction
[0028] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] This embodiment is realized based on the DM642 embedded platform. The image acquisition unit is a 2 million-pixel high-resolution CCD, which can provide 10-bit high-definition images, which are transmitted to the designated memory location of the DM642 embedded platform through EDMA.
[0030] The present invention provides a fast image processing method, which specifically includes five steps: parameter initialization, image acquisition, image analysis and adjustment of data mapping table, image processing and image compression, as shown in the attached figure 1 shown.
[0031] Step 1: Parameter initialization. In order to improve the operation speed, the bit adaptation mapping table and the RGB color mapping table are combined, which is called the RGB bit adaptation mapping table, that is, the RGB bit adaptation mapping table is used to compl...
