The technology has revolutionized the concept of capturing live images. The earlier concept of producing permanent photograph was on pure chemistry. In 1830, Louis invented Daguerre, the first practical method of producing permanent photographs. Today we talk about the computerized photos in the Photo filmless image of a device that electronically Intelligence and made smart appearance - digital camera.
A digital camera takes video, still photographs, or both, digitally. It records images on a light sensor. Instead of stores with a film, an arrangement of charged-coupled devices, photosensitive semiconductor, the electrical charge, does the job. These digital sensors which consist of pixel-transform the light from the scene, went into an analog signal, which has subsequently been converted into a digital format. An electronic filter system controls the color and other visual components. Another system reduces the image. The image is finally sent to a temporary storage area and ultimately to a card. Many compact digital cameras can capture Sound, video and stills.
The images are transmitted to a computer where they can be modified, printed, attached to e-mail, pasted into Web pages, etc. The main advantages of a digital camera, the memory capacity and the ability to screen view images on a small monitor.
Technology the digital camera refers to the same technology from the VCR. The first VTR in 1951, captured images of the television by converting the information into electrical Impulses (digital) and then save it on tape. It was in 1960, when NASA had a major breakthrough made by the conversion of analog to digital signals using the spacecraft to map the lunar surface. Also had its other digital imaging applications in spy satellites.
Kodak scientists invented The first mega-pixel sensor recording 1.4 million pixels. 1991 Kodak released the first digital camera system, a Nikon F-3 camera equipped with 1.3 megapixels, aimed at journalists. The first digital camera for consumers who worked with a home PC through a serial cable were the Apple Quick Take camera 100 (1994), the Kodak DC40 camera (1995), Casio QV-11 with LCD monitor (late 1995) and Sony's Cyber-shot Digital Still Camera (1996).
The main features of a digital camera can be summarized as follows:
Resolution: Resolution Central sharpness of an image. The higher the number of pixels, the higher the resolution.
Memory: The pictures as a file stored in a digital camera. The amount of memory determines the number of images that can be taken, stored and downloaded into the computer will.
Flash Type: Most digital cameras have a built-in flash with a range of approximately 10 -16 meters, which is necessary for additional Light needed to provide photos to insufficient light.
Optical Zoom: use in general, two types of zoom lenses that is., Digital and optical. The optical zoom lenses tend to serve the purpose as adding detail and sharpness.
Compression: This process helps to reduce the file size.
Lens: The length of a lens designed to fit as much of a scene in a picture.
LCD screen: A very interesting feature of a digital camera is the LCD screen that allows you to see what the picture will look like before and after the taking of photographs, to decide what area, whether to delete or save the photo.
On the market there are several brands of digital cameras that have been successfully selling and continuous improvement in technology is leading the way for the introduction of more and more interesting features in the digital camera.
