To use a computer to handle the digital image, you must first have a clear understanding of the file format of the image, because we have said before, the image of the nature is exist in the form of analog signal, before using the computer, first quadruple, such as The signal ingestted by the camera (CCD) is in general, in general, in general, in general, the task is often completed by the image acquisition card, which is generally in the form of naked charts; if the user wants to generate the target image file , Must be processed according to the format of the file. With the development of technology, digital cameras, digital cameras have entered ordinary people's home, and we can use these devices as input devices for image processing systems to provide information sources for subsequent image processing. No matter what device, it always provides information on a certain image file format, which is commonly used with BMP format, JPEG format, GIF format, etc., so we must first have the format of the image before the image processing. Clear understanding, only further development processing can be performed on this basis.
