In this hi-tech world of high-speed life everyone wants that their work be done fast and fine. With the help of digitalization, all consumer electronics are being developed to give you quick performance with optimum results. One such category is high speed digital cameras. These high speed digital cameras are specially designed for advanced professional and industrial usage. Let us try to understand the concept of high speed digital cameras in detail.
When you want to capture multiple images quickly you want to depend on high speed digital cameras. These cameras are primarily used in industrial and scientific applications where processes move quickly and photographs must capture excessive rates of speed. Whether you need monochromatic or color photos, these cameras easily do both.
Monochrome basically refers to the projection of image in back or white, or in complete grayscale. On the other hand, the varying combination of discrete colors generate the range of colors. One such prominent method is RGB or red, green and blue. The RGB technique senses the red, green and blue components and then conjoins these components to form an extensive spectrum of colors.
There are some major features which decide on the performance of a high speed digital cameras. These features are horizontal resolution, maximum frame rate and shutter speed. Horizontal resolution refers to the highest amount of individual photo elements which can be differentiated in one scanning line. This feature is very essential for characterizing correct horizontal video resolution for image aspect ratio. Moreover, it is also used to specify the resolution in the biggest circle which can fit in a rectangular image. Now for example an 800x600 image would be specified as 600 horizontal lines.
Maximum frame rate refers to the greatest number of photos that can be taken in the specific time period. In photography time periods are usually counted in seconds. Finally, shutter speed refers to how much light the camera lets in during the time the shutter button is pressed. This is an individual choice and can be set across a wide range, depending upon the subject and light conditions.
There are two basic types of high speed digital cameras. There are CCD and CMOS. CCD is short for charge coupled devices. The CCD is made up of a light sensitive silicon chip. As light hits the CCD the silicon chip begins converting the light into electrons. The chip then carries these electrons across the chip where they are read at one corner of the array. With the help of an analog-to-digital converter, the amount of electrons at each photo site is measured and then they are converted into the binary form.
CMOS refers to the complimentary metal oxide semiconductor. CMOS technology is also used to convert light into electrons. A CMOS uses a variety of transistors in every pixel to move and amplify the charge using traditional wires. The signals of CMOS don't require conversion into digital form as they are already digital. The CMOS image sensors consume low power as they operate at lower voltages than the CCDs.
The most popular choices for digital output include Ethernet, RS232, DeviceNet, CANbus, USB, SCSI, modem and wireless. The usual choices for the number of megapixels can vary from 8 bits to 16 bits. Even the color output can vary from composite, RGB or S-Video.
Some of the prominent physical features for the high speed digital cameras include radiation hardened, underwater rated, outdoor rated, goose neck, board mount, pan or tilt and remote head.
