A digital camera take pictures in digital format, unlike a traditional camera that records images with a photographic film.
History:
Using a mosaic photo sensor, Eugene F. Lally of the Jet Propulsion Laboratory first images showing how more can be produced in the digital domain. From an Eastman Kodak engineer Steve Sasson, used solid-state CCD 0.01 prototype of a building with a resolution digital cameramegapixels, and record images in black and white is a magnetic tape. With this prototype model, Steve was the first image in December 1975 took 23 seconds to capture.
In 1988, DS-1P is the first Fuji digital camera image files like a computer. But the camera never entered the U.S. market. In 1991, the Kodak DCS-100 was the first commercially available digital camera that uses a 1.3 megapixel sensor. With the development of technology, modern digital cameras have become multifunctional and are now able to record audio and video images.
Advantages:
1 – You can get better image quality. Digital cameras offer a good resolution picture quality.
2 – You can get a fair price. A digital camera is relatively cheap and convenient.
3 – You can transfer images to a laptop. You can easily connect> Digital camera to your laptop and transfer pictures to your hard drive.
4 – You can print in large sizes. Because of high resolution photos can be printed in large measure by a plotter.
5 – You can send photos with friends. You can send pictures via e-mail to your loved ones.
6 – You can save images on a CD or disk. When the photos from your digital camera to your computer, permanent storage on a CD or harddisk is possible.
7 – you can take the camera in his pocket during the trip. The small digital camera makes travel easy and fun.
8 – You can move close to your subject. Click on the lenses offer close-up of the subject with a strong focus. It may well closeups of flowers, insects, stamps, coins, etc.
9 – You can recast the image of a computer. Any photo editing software can rework the photos taken.
10 – Canto take good pictures even in low light. Due to the sensitivity or ISO equivalents than flexible, digital cameras can be easy to take detailed pictures even in low light conditions.
11 – You can still quality photos of moving objects. Sport and fashion photography can be easily achieved due to the outbreak of rapid digital cameras.
12 – You save money. No need to buy film, developing them in negative and positive. Moreover,The batteries are usually rechargeable lithium ion battery that lasts long.

Strength:
Digital cameras consume a lot of energy that comes with a powerful, small-size batteries. Batteries are broadly divided into two groups, ie, off-the-shelf and property. Off-the-shelf batteries are like AA, CR2,CR-V3, AAA, and RCR-V3. They are lithium ion (Li-Ion) or nickel metal hydride (NiMH). The standard non-rechargeable AA alkaline batteries or not work or work only for a short period of time in most cameras.
Proprietary batteries are built to custom specifications of the manufacturer and are usually available as succeeding. Typically, most ion batteries as lithium batteries for its own digital cameras.
