The Early Digital CameraA digital camera is basically a digital device that enables images to be captured. Digital camera 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 digital camera LCD. Although the digital camera 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 digital camera 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 camera, 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 pioneer in the history of digital camera was Steve Sasson, an engineer at Kodak. Digital images were of the moon were being transmitted via satellite by NASA, using a mosaic photo sensor, and he saw the possibility of a digital camera for commercial use. In 1972 he began to group together available equipment used within the film industry to create an image digitally rather than on film. Central to this early concept of the digital camera, and still used by digital cameras today, is the Charged Coupled Device. The CCD detects light and colour intensity and then converts this information into electrons. The value of each cell in the image is then read, and converted to binary format to make the image computer compatible. Steve Sasson produced his first digital camera image in 1979. The image took a total of 23 seconds to take, and a further 23 seconds to read from the playback unit. Although the digital camera image was less than perfect, it showed that the digital camera was a possibility. Kodak had developed a camera that developed picture from light, but it was never manufactured for the public. The first camera to be marketed was the Sony Mavica electronic still camera in 1981. It was not a true digital camera as the image was recorded on mini disc, and then attached to a television or video. It was more a freeze frame video camera but it greatly influenced people`s attitude to the recorded image. It made public the possibility of a camera that stored images using techniques other than film. It still used more television technology but was the first hand held with the general idea of digital camera usage. Cameras that could transmit images via satellite became popular, but were used by the media only due to the expense incurred. The possibilities were becoming apparent and images were used for news coverage. The first camera for general use with a computer was the Apple Quicktake 100 camera which appeared in1984. In 1986 the Canon RC-701 was used for coverage of the Olympics, with quality images printed in the newspaper. This showed the possible quality, and the desire for the digital camera was born. The first mega pixel sensor was invented in 1986. It contained 1.4 million pixels and was suitable for a digital camera image measuring 5x7 inches. In 1987 accessories for storing, printing, manipulating, transmitting, and recording digital images came onto the market, with the Fuji DS-P1 arriving in 1988. This is arguably the first true digital camera as recognised today, boasting a 16MB memory card. With the arrival of JPEG and MPEG standards in the 1990´s, the face of the digital camera was changed for ever. Kodak marketed the first readily available digital camera that met all standards, with the Kodak DC40 in 1995.

Have you Forgotten the History of Digital Photography?
There is a saying that a picture is worth a thousand words. This is very true but to get this thousand word picture you need really high quality cameras or digital cameras. While many of us take for granted the presence of digital cameras and the many marvelous things that they can do we have forgotten the history of digital photography.
This history of digital photography is not that long but the events that took place have changed the way that we take our photographs.
In 1969 October 17th George Smith and Willard Boyle invented the charge coupled device or the CCD as we know it. This device was originally made for use in computers as a semi-conductor memory. These inventors of the CCD were also thinking about ways to incorporate their device into video phones.
With all of their plans and sketches finalized Smith and Boyle finally built the CCD into the world’s first CCD camera. This changed the history of digital photography altogether.
The camera that was built by them was a solid state video camera. During 1975 the CCD camera with its image sharp pictures was shown on television for the first time. The image that was shown was clear enough to be seen by the viewers of television.
In the history of digital photography the first prototype of the digital camera was created by Sony in1981. This digital camera was called Mavica which meant Magnetic Video Camera. The Sony Mavica was essentially a video camera that was used to capture video freeze-frames.
In 1986 Kodak scientists invented the first megapixel senor. This senor was capable of recording 1.4 million pixels. These were capable of producing a 5 x 7 inch digital photo quality print. In 1987 Kodak released 7 products that had the ability to manipulate digital images.
In 1991 Kodak in partnership with Nikon, released the Nikon F-3 camera. This camera was equipped with a 1.3 megapixel sensor by Kodak. This shows how the history of digital photography merged scientific know-how to produce a digital camera.
At about this same time Logitech produced and released their Dycam model with black and white images. Apple produced a digital camera that could transfer images to the computer from the camera.
This is the short version of the history of digital photography. Today 30 years after the first digital camera was produced and released digital photography has changed our lives. The next time that you buy a digital camera you might want to see what other information you can find out about the history of digital photography.
