The joy of modern technology means that we expect things to be done quickly yet we refuse to let quality take a back seat. Digital technology has let us tap into amazing speed joined with astonishing performance. No where can we see this more than in electronics; specifically, digital cameras. High speed digital cameras were expressly designed for advanced professional and industrial use. Confused? Let me expand this digital photography tutorial in a bit more 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.

Monochromatic photos can be in either total black and white or a combination of both which gives you more of a grayscale photo. High speed digital cameras operate on the RGB color scheme which ends up generating a range of colors. RGB senses the red, green and blue components in the image and then blends these components together to form an extensive spectrum of colors.

High speed digital cameras are defined by a variety of unique features. These features include horizontal resolution, maximum frame rate and shutter speed. When I say horizontal resolution I am talking about the highest amount of individual photo elements that can be distinguished in one scanning line. This is an essential feature for characterizing correct horizontal video resolution for image aspect ratio. Horizontal resolution is also used to specify the resolution in the biggest circle which can fit in a rectangular image. For example, an 800×600 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.

When it comes to high speed cameras you have two basic choices: CCD and CMOS. CCD is short for charge coupled devices and 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.

As with other digital cameras users can choose between Ethernet, RS232, DeviceNet, CANbus, USB, SCSI, modem and wireless for digital output. Megapixel choices 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, gooseneck, board mount, pan or tilt and remote head.
