Today, advancements in technology have allowed humans to view images in ways that they never imagined to be possible. The technology known as 'digital imaging' has given people the ability to drastically progress in such areas as communication, science, technology, medicine and much more. Advanced digital imaging has had a tremendous positive impact on the daily lives of people all over the world.
What is Digital Imaging?
Digital imaging is the process of creating digital images in such forms as computer images, illustrations, photographs, graphic presentations, computer files, artwork, printed texts, and more. As well, there are imaging systems that can scan the human body down to its molecular structures and then generate an image of the structure. For instance, high resolution small animal imaging systems have become essential in small animal research when studying diseases such as cancer. The development of high resolution in vivo micro imaging systems have allowed medical researchers to discover new opportunities in the field of medical and scientific research that were once thought impossible to achieve.
A digital image is made up of a group of pixels. Each pixel within the collection of pixels that make up the image has its own tonal value known as a bit-depth value. This tells the computer imaging system what color to display. The tonal value of each pixel is coded which is called binary code. The binary digits for each pixel are called 'bits.' The computer reads the bits to establish the analog display of the image. The collection of pixels creates the combines image. The pixels are mapped onto a triangular grid and stored by a computer. The image created can be manipulated by users for their specific needs to be displayed or printed.
The Quality of Digital Imaging
Common imaging systems include: digital cameras, image scanners, various medical imaging equipment such as ultrasound, X-RAY machines, electron microscope...etc. The quality of the digital images depends on how the image is created, how the image is stored, how the image will be used, and the type of digital imaging system that used to create the image. When it comes to computers, digital images are stored in a number of formats such as GIF, JPEG, TIFF, and BMP. GIF, JPEG is the choice for web pages, or TIFF, Tagged Image File Format, is normally used for scientific imaging. To view images beyond the naked eye such as images acquired using tomographic equipment, a more intricate digital image process is utilized. As well, a digital image can be created from a mathematical formula.
Digital Imaging Today
Today, everywhere we look digital images are having a positive impact on our lives. They are used in cell phones and other hand held devices, personal computer, business computers, and in science, health, and other areas that utilize imaging technology. Digital imaging has become an essential component of our technologically driven society.
Digital imaging has had a profound impact on society and is playing a key role in future developments in a variety of areas that touches us all. It will be fascinating to see what the future brings as digital imaging continues to grow in leaps and bounds.
