A digital camera is basically a device that enables images to be captured. The images are stored electronically rather than on film. This process involves converting light into electrical charges, and then translating this back into the image that was seen through the camera LCD. Although the device is a recent addition to the world of photography, the concept of the possibility of a digital camera was begun in the 1950s.
The early concept of the digital camera was closely linked to television technology. It began with digital images being recorded on scanners and in the form of digital video signals. In 1951 broadcasting companies were recording images as electrical impulses and onto magnetic tape from their television cameras, and this paved the way for digital camera technology to begin. By 1956 electrical impulse recordings were common practise within film industry, and camera manufacturers began to dream of a device.
The first record of a patent for a type of digital camera was in 1972 when Texas Instruments patented a camera that did not require film. However, the patent revealed a more analog based design rather than a digital device, and there is no record of whether the camera was actually created. What the patent does show, however, is that interest towards a digital camera was growing with the idea that the need for film could be removed. A
