DIGITAL CAMERA

The digital camera is a device that has evolved and is a clear example of technology changing now underway in our days. Since its inception in 1974 with the invention of the CCD and the modification of lens and memories, the digital camera has been modified and evolved into the gadget we have. Starting from 1969 The Bell’s laboratories in the USA, invented the CCD able of transmitting electrical charges. This allowed the scientists to modify it in order to make a CCD able of taking images and keep them.

For 1974 many companies had done with the rights of the CCD, which offered pixels 100x100.This was thanks to Willard Boyle and George Smith. Although the Sony Mavica (Magnetic Video Camera) is considered by many the first digital camera, during the decade of the 70 Texas Instruments patented the system electronics and photography pioneer Kodak entered the scene by presenting the prototype of the first operating chamber with a CCD.

In 1975 the engineer Steve Sasson created the first digital camera, initiating a revolution on digital images, this one kept pictures on a tape cassette and took, 23 seconds to capture its first photograph in December , also it integrated electronic systems, visual sensors, backup systems and digital information processing, in cassettes. The “Mavica camera” was developed by SONY in 1981; they used removable disks as their main recording media.

Following this, many manufacturers interest in new sensors, such like Casio and Panasonic, Fujifilm ES-1 and Nikon SVC presented this one’s as their first prototypes inventions. The Fujifilm DS-1P also introduced flash-removable memory for storing images in 1988 also they were the first to replace magnetic storage of images on a memory card that stored the digitized data.The tiny Sony DSC-F55 (2.1 MP), meanwhile, is the first camera that used Memory Stick as a storage mass. In 2000 the Nikon D1, integrates the best digital technology of time.
