History Of The Digital Camera
Digital cameras have become commonplace in recent years as rapidly evolving technology makes them more compact, capable of higher quality images and easier to use. Their roots lie in spy satellites and space probes that mapped the surface of the moon in the 1960s and 1970s, but it wasn’t until the mid-1990s that they became available for consumers. If you have ever been interested in the history of the digital camera, here it is.
Where it all began
The first digital images were created in 1951 when live video images were captured by a video tape recorder with the information converted into electrical impulses and saved onto magnetic tape. In 1956, video tape recorder technology was perfected and put mainly into use by television stations. While it is not the digital we know today, it is the forbearer of modern digital images.
The First Cameras Ever Invented
Your new Olympus digital camera is going hot, it’s got all sorts of menus and settings and different functions to pick from. There’s a camera in your laptop and even one in your phone. But as you stare at this great contraption you wonder – where did it come from? Who thought of this technology in the first place? The digital camera is a lot older than you think!
In Ancient Times
One of the very first instances of the early camera is the ‘Camera Obscura,’ the starting point from which modern-day digital cameras evolved. Its invention was recorded by the Chinese and the Greeks in ancient times when these crafty guys first began to figure out how light worked. But it wasn’t until an Iraqi mathematician named Ibn al-Haytham came onto the scene and began to form these ideas into something concrete. He created a kind of dark room with a pin-hole in one wall where light filtered in through the hole and projected an image onto the opposite wall. This pinhole became the first instance of the camera lens. And even more impressively, they would trace the projected image onto paper in order to ‘capture’ the picture, giving us the very first instance of the ‘photo.’ Read more »
