The digital magnification is the amplification effect caused by the CCD light sensing module in the entire process of displaying image information onto the display screen based on the power supply circuit. The table shows the magnification from CCD to display screen. There are four common sizes of CCD light sensing chips: 1/3 ", 1/2", 2/3 ", and 1". There are five common sizes of displays: 9 ", 12", 13 ", 17", and 27 ". From the table, the magnification from CCD to display screen can be found. The specific ratio between the precise measurement of the specific size of the object and the image size of the display screen is the image magnification. The detection system of the anime image measuring instrument is used to optically magnify the object to be measured through the camera lens. The whole process of the image transmission through the digital data signal display screen is also magnified. The magnification from the object size to the image size is called the image magnification. The magnification calculation method of anime image measuring instrument is as follows: image magnification=optical magnification × Digital magnification. The magnification of the anime image measuring instrument includes two levels of magnification: optical magnification and digital magnification. The magnification based on the geometric imaging principle is called optical magnification, and the magnification of the displayed information after the electronic circuit is solved is called digital magnification. The optical magnification is the magnification at which an object is imaged onto the light sensing module of the CCD using the camera lens.
These are pure optical images that follow the fundamental principles of geometric optics. The optical magnification partially determines the magnification of the image, and also partially determines the range of line of sight that can be seen by the CCD. The digital magnification is the amplification effect caused by the CCD light sensing module in the entire process of displaying image information onto the display screen based on the power supply circuit. The table shows the magnification from CCD to display screen. There are four common sizes of CCD light sensing chips: 1/3 ", 1/2", 2/3 ", and 1".
