History of digital cameras

One of the first digital cameras was SONY ProMavica MVC-5000. It has appeared in 1989. The word "MAVICA" stands for Magnetic Video Camera. The camera worked as follows: it recorded images as magnetic impulses on a compact 2-inch still-video floppy disk. The images were captured on the disk by using two CCD (charge-coupled device) chips. One chip stored luminance information and the other separately recorded the chrominance information. This camera provided a 720,000-pixel image. The images could be stored on the floppy disk either in Frame or Field mode. When Frame was selected, each picture was recorded on two tracks and up to 25 images could be recorded on each disk. When Field was selected, each picture was recorded on only one track, allowing up to 50 images to be recorded. When recorded in the Field mode, images were less detailed as compared to images recorded in the two-track Frame mode. The MVC-5000 was considered to be the leader in image quality during its time.
