A camera that takes photographs and videos by recording images digitally via an electronic image sensor is called a digital camera. Film cameras cannot do what digital cameras can: deleting images to free storage space, recording video with sound, on a single small memory device it stores thousands of images. The light is focused onto an image pickup device by using a lens with a variable diaphragm. The correct amount of light to the image is admitted by the combination of shutter mechanism and diaphragm. Here are several types of digital cameras: integration, line-scan camera systems, digital rangefinders, electronic viewfinder, digital single lens reflex cameras, bridge cameras and compact digital cameras.



The camera sensor influences the resolution of a digital camera, a CMOS sensor or CCD. Light is turned by a discrete signals. The photons are made of millions of, buckets’’. The larger the value that is ready for that pixel, the brighter the image at a given point on the sensor. The pixels count is determined by the number of resulting pixels. For example, 307.200 pixels would have a 640x480 image, 10.036,224 pixels would have a 3872x2592 image. The other factors that have an impact on the resolution are: the organization of the pixels, lens quality and sensor size.

A multinational conglomerate corporation that has the headquarters in Tokyo, Japan is called Sony Corporation. Sony is one of the leading manufacturers of  information technology products, video games consoles, communications, video and electronics for professional markets as well as for consumers.

Bucking the trend toward higher resolution and greater complexity, with a new focus on affordable beginner optics, lower-cost cameras and greater simplicity, Sony has revamped their consumer digital SLR line. The sony digital cameras, A380, A330, A230 have more things in common than differences with their predecessors. Shape categories, weight and size are the main changes that occur. All 3 have unchanged resolution. 14.2 megapixel sensor for A380 and 10.2 megapixel sensor for both A330 and A230.

To avoid confusing the user, Sony A230s has fewer buttons. Replacing the 18-70mm lens previously used, 18-55mm lens are now used. The new lens design is lighter and shorter. Still offering high optical quality, the new electronically linked lenses are designed to be less expensive. Sony A230 includes support for both Secure Digital Cards and Memory Stick Duo. A new self-timer mode, bigger AF points are some of the improvements of Sony230. Each of these 3 sony digital cameras is a slight rewrite of the other. But in some aspects are pretty unique: autofocus abilities and colour rendering. The best overall choice is Sony A330.

Sony Cyber-shot S2100 has 100% coverage being a 3.0-inch TFT Clear Photo LCD and resolution of 230.400 dots. This serves as the only method of reviewing images and framing. An optical viewfinder isn’t featured. Sony DSC-S2100 is capable of detecting up to eight faces in a scene, includes a face detection system and a 9-point autofocus system. In order to provide a Smile Shutter function an automatic trigger that shutters when the subject is smiling, is provided.

S2100 offers 3 methods for determining exposures: spot metering, centre-weight and multi-pattern. Under automatic control, shutter speeds from 1 to 1/2000 second are possible and ISO 100 to 800. No form of optical image stabilization is offered.

Sony S2100 doesn’t have a manual white balance setting. Eight scene modes are available : Gourmet, Snow, Beach, Landscape, Soft Snap, Twilight Portrait, Twilight and High Sensitivity. These scene modes can be selected can be automatically selected. A flash strobe with red-eye reduction capability is included by S2100. When using automatic ISO sensitivity, flash range is stated as 0.5 to 3.3 meters. Movies and images can be recorded on Sony’s Security Digital High Capacity cards, Secure Digital, PRO-HG Duo cards, PRO Duo High Speed, PRO Duo and Memory Stick Duo.

Digital cameras are integrated or built in many devices such as mobile phones, digital camcorders, BlackBerry devices, laptops and PDAs. At the very lowest end of the digital cameras’ scale are the integrated cameras in technical specifications such as: the ability to use accessories, optical quality, resolution.

Photos can be printed directly from the printer through an USB cable. The USB allowed play and plug facility in all devices. Batteries are not necessary because the device draws power from its host, you just have to plug in equipment. The PICT bridge is the connection between printers and camera. It is developed by CIPA. With the help of an USB, the camera can be simply plugged into the printer. One touch and you can print quality photographs.  The popularity and wide acceptance of PICT bridge makes CIPA succeed in doing a great job.

The surveys conducted from 1997 show a rising penetration of digital cameras. Users show greater differences in preferences. Conducting a digital camera comparison before you buy a camera is of great importance. Today are available a multitude of options. You can find yourself overwhelmed and get lost if you do not take a comparison. Most people are not aware of the price range they should aim for, the brands that they should trust or the features they should be looking for.
