ABSTRACT:
There is disclosed a magnetic recording system for a digital still video recorder. The system includes a sensing unit 10 for sensing release timing data and white balance correction data and exposure data, a CPU 20 for generating control signals, an image sensing unit 40 for receiving image of object through a lens and for converting optical signal into the image signal and for amplifying the image signal, and then for performing chrominance separation, gamma correction and the white balance correction, an external image signal input unit 50 for separating R, G, B chrominance signals from composite image signal to amplify the R, G, B chrominance signals, and for separating synchronizing signals from the composite image signal so as to apply to the CPU 20, an input selection switch 60 for generating an input selection control signal, an input selection circuit 70 for selecting one image signal of the image signals which are generated from the image sensing unit 40 and the external image signal input unit 50, a digital signal processing unit 80 for converting and processing the image signal into digital image signal, a magnetic data recording unit 90 for recording the digital image signal on a disc and a display unit 100 for displaying a status of the magnetic data recording unit 90.
