Industrial camera by an imaging device into electric vacuum pickup device (ie camera tube) camera and solid-state imaging device (CCD devices, CMOS device) camera two categories. Electric vacuum camera tube developed early variety, but the high cost, large volume. Has been replaced by general television monitoring system used solid-state imaging device. The latter is developed a new type of imaging device, and its advantages are: inert, high sensitivity, anti-glare, geometric distortion, uniformity; impact vibration, no sound should be slightly; small and light, life long. Industrial camera is moving small, lightweight, inexpensive technology, and improve image quality, increase operational functions direction. Mainstream industrial CCD camera is based on the basic CMOS photosensitive member and the photosensitive member to points.
CMOS (Complementary Metal-Oxide Semiconductor, complementary metal oxide semiconductor), the sensitivity of the CMOS sensor is usually in the range of 6 to 15Lux, CMOS sensors have a fixed 10 times higher than the CCD sensor noise, fixed pattern noise always remain on the screen All cameras on a pattern like that is because CMOS sensors 10Lux following basic useless, and therefore a large number of applications are using CCD sensors, CMOS sensors are generally used for very low-end home security. But there are two exceptions, CMOS sensors can be very large and have the same sensitivity and CCD sensors, CMOS sensor is very fast, faster than the CCD sensor 10 to 100 times, making it ideal for special applications such as high ens DSC camera (Cannon D-30) or a high-frame camera. CMOS sensors and controllers are all logic on the same silicon chip blocks, you can make the camera simple and easy to carry, it can be made very small CMOS camera. Although CCD cameras and CMOS cameras energy equal or slightly higher, but a few CMOS sensor chip as CDS, TG and DSP, so the total energy consumption of the same size than the CCD camera decrease of 1/2 to 1/4. Although the CCD that "Charge Coupled Device", and said CMOS "complementary metal oxide semiconductor", but regardless of CCD or CMOS image sensors are not used for real inductive sensor called "semiconductor image", CCD sensor and a CMOS sensor (for the time being so called) are the same kind of sensor "image semiconductors", the image of the semiconductor is a semiconductor PN actual use, able to convert photons of light explosion junction becomes proportional number of electrons. The number of electrons is calculated signal voltage, the more light into the semiconductor image, the more electrons generated from the sensor output voltage is also higher. CCD is called "charge-coupled device," is really just a method of CCD put out electrons from the semiconductor image stored in an organized manner. CMOS called "complementary metal oxide semiconductor", CMOS technology is really just the transistors on a silicon block, no more meaning. CMOS sensors are known only to distinguish the CCD sensor the sensor, regardless of the real image of the sensor processing method. CMOS sensors do not require complicated processing, semiconductor electronic images directly into a voltage signal generated, and therefore very fast. This advantage makes high-frame CMOS sensor camera is very useful for high frame rate can reach 400-2000 / sec.
CCD (Charge Coupled Device, photographic coupling assembly) for the digital camera can record changes in the semiconductor light), is taken through the object lens to focus the image onto the CCD chip, CCD accumulation depending on the intensity of light corresponding to a charge ratio of each pixel accumulation the charge control in the video sequence, by point outward, filtered, after enlarging processing, the formation of the video signal output. Video signal to a monitor or TV's video input terminal can see the original image the same video images. Either monochrome or color camera cameras are CCD electronic scanning itself by the light signals into electrical signals, the photoelectric transformation devices are devices using a CCD, CCD is electrically coupled device (Charge CoupleDevice) for short, and therefore also known as is coupled cameras. It is through the use HYPER HAD (HOLE ACCUMU-LATED DIODE, hole accumulation diode) CCD technology. When the subject light is reflected, transmitted to the lens by the lens is focused on the CCD chip, CCD accumulation according to a charge corresponding to the intensity of light by periodically discharging said electrical signal to produce a picture is, after filtering, amplification, shaping, DSP (digital signal processing) and a series of processing, the output terminal of the camera by a standard composite video signal. The standard video signals with home video recorders, VCD machines, home video camera's video output is the same, so it can be connected to a TV or video viewing. The main camera is coupled to the sensor component CCD, it has a high sensitivity, distortion, long life, anti-vibration, anti-magnetic, small volume, no blur characteristics, it can charge the light changed and the charge storage and transfer , the charge can be removed to save the changes in the voltage, and therefore is an ideal imaging element. Is replaced by a new type of camera tube sensor devices.
