Latest Advances in Digital Cameras
Digital cameras are electronic devices which are used to capture and store photographs in a digital format, which could be transferred to other sources and also could be printed. They are unlike the conventional camera which uses photographic film to produce pictures or video cameras that record images in an analog format.
One can determine whether a digital camera has been built with the latest technology by having a quick look at its specifications and features.
- Image Resolution and Pixel Count
- Methods of Image Capturing
- Filter Mosaic
- Battery Power
- Image formats
One of the most important factors you have to consider while buying a digital camera is its image resolution and pixel size. Resolution refers to the number of pixels in an image. Pixel is the short for picture element. The resolution of an Image is identified by the width and height of the image as well as the total number of pixels in the image. For example, an image has a resolution that is 1600 pixels wide and 1200 pixels high (1600X1200) contains 1,920,000 pixels (or 2.0 Megapixels approximately). In other words if your digital camera has a higher megapixels count this increases the possible maximum size image you can produce. The latest available digital camera today is 10 megapixel.
Latest technology cameras use the scanning method of image capturing instead of the single-shot or multi-shot method which was introduced earlier.
Filtering of colors is another important technology that has been put into digital cameras. This is usually done by software which interprets the raw data from the sensor to obtain a full color image.
The latest digital cameras can connect to the computer in many different ways. For example you could connect using the USB port, Wireless Connection, Bluetooth, Card reader or a Wi-fi. Some cameras don’t need a computer to connect to print but rather they use the pictbridge standard which allows sending data directly to the printer.
Another latest advance in digital cameras is that they come integrated in a number of other devices such as mobile phones, PDAs, Black berry and laptops.
Storage capacity of memory stick on today’s digital camera has increased considerably from 32 MB to 4 GB.
The batteries being used now on digital cameras are small in size and last for a reasonably longer period of time and have a higher rechargeable cycle.
The latest technology cameras allow you to use the following image formats JPEG, TIFF and Raw. The format for movies is AVI, DV, MPEG, MP4, WMV and MOV.
