Evolution Of The Digital Camera
Remember the good old days, when buying a digital camera meant choosing between two or three models? That was the year 1995, and there were literally only three digital cameras which had been introduced for the consumer level market-the Apple Quicktake 100, the Kodak DC40, and the Casio QV-11. Back then, it was easy to get information about each camera and decide which would work best for you. Well, those days are definitely gone. Now, if you want a new digital camera you’ll have to sort through hundreds of different models and make countless decisions, like how many megapixels you’d like your camera to have, what type of media you want your camera to store your images on, and what levels of digital and optical zoom you’ll need…not easy tasks, especially if like me you’re not sure what a megapixel is.
I recently decided that my old film camera needed an update and made the momentous decision to buy my first digital camera. Though I’ve always been one of those people who shies away from new technology, friends and family had been telling me for years that it was time to go digital. According to them, the benefits of having a digital camera far outweighed my fear of high-tech gadgets. They told me that I could save a fortune on film and developing costs, that I could view my pictures instantly, edit them on my own computer, and print only the ones I wanted. So, I decided it was time to jump on the technology bandwagon and find myself a simple little digital camera.
Easier said than done.
Several disappointing trips to the electronics stores in my area left me confused and camera-less. I’ve never been intimidated by salespeople, but the electronics stores were completely overwhelming. I had no idea there were so many digital cameras on the market today and had trouble even understanding what the salespeople were talking about when they pitched their products! Megapixels, CF, CCD, dpi, MMC…does anyone know what these terms mean? Finally I decided to try my luck on the Internet, where I could at least conduct the search on my terms, without hovering salespeople, in the comfort of my own home.
I tried the big online shopping sites first, but found most of them even more overwhelming and confusing than the stores. I’ve been using the Internet for years, but I had difficulty finding my way around most of these sites. Not only that, but there were even more digital cameras to choose from than in the stores! I hadn’t thought it possible. I needed guidance…unbiased guidance in language I could understand.
Finally, I came across a new website called www.techselector.com. The site promised to help me find the right product every time-in four simple steps. After my previous experiences I had my doubts about this, but decided to give it a shot. I was instructed first to choose the category of product I was looking for – digital cameras – and then to complete a short multiple choice questionnaire. I expected the questionnaire to be tedious, full of terms I wouldn’t understand, but it wasn’t. It was simple, and any technical terms were explained to me in everyday language. After I completed the questionnaire, the site generated my own personal Product Report, which listed the best products for me based on my questionnaire answers. The Report was easy to understand – I could see pictures of the products, view detailed specifications sheets, and compare different products. After a few minutes of reading through my Product Report, I made a decision and with the click of a button, I purchased my first digital camera.
Sure it’s not 1995 anymore and there are considerably more than three digital cameras to choose from, but the cameras today have amazing features we couldn’t have even imagined back then. Don’t let the overwhelming selection of available models and the confusing technical jargon deter you from getting a great new camera-or any other new high-tech gadget. Techselector.com features a number of different product categories, tech guides, and glossaries which can help you understand all the terms and features. Best of all, the site can help you to sort through the different products and find the ones that will suit you best – quickly and easily. My new digital camera arrived a few weeks ago, and already I’ve almost forgotten what it was like to buy film. Had I known it would be so easy to find the perfect digital camera for me, I’d have done it a long time ago.

The Early Digital Camera
A 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 5×7 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.
