Digital Camera

Product Description


    The working principle of digital camera is that lens gather beam to sensitization device CCD, CCD transforms light signal to electric signal, in this way the according electronic image is got, but it can not be sent to computer for processing right away, it still needs modulus processing, then MPU compresses the digital signal and transforms it to specific image format, such as JPEG format, finally the image is stored in storage which can be viewed through LCD. Diodes and transistors and zener IC of KEXIN can be applied at this circuit widely.
