hi all. i really need your help. i have colorimeter which can get the information about RGB, luminance of light source such as LED. but i don't know where the colorimeter get the information from and how? recently i found so many articles about CCD. and i understood, the CCD Camera can get the value of luminance of light source. CCD is just a image sensor. when i take a video of LED , each cell of CCD has information about electric charge and CCD analyse brighteness based on electric charge. and it can be display as a signal. that's just a theory. i need, how can i get the information about luminance!?? i'll take a video of LED using CCD Camera or special colorimeter, and connect it to computer so that i can get the information. does anyone can let me know? please help me thanks
What else can I help you with?
Internal block diagram of digital camera with explanation of each block?
A Digital Camera is used for record and store the images or photo in a digital form. Today many models are available that also used for record sound and video also. A digital camera is very use full to capture a image and after that store it in computer and processing it and print... In a digital camera a key for press or record a image or capture a image. Flash- it is a lighting device that is automatically on when the shutter key or button was pressed... it give a better effect in night. Memory Card- its simply store the image that was captured. Lens- its used to set camera on a object CCD- its called Charged Coupled Device(CCD)
Who was Steven Sasson?
His invention began in 1975 with a very broad assignment from his supervisor at Eastman Kodak Company, Gareth A. Lloyd: Could a camera be built using solid state electronics, solid state imagers, an electronic sensor known as a charge coupled device (CCD) that gathers optical information. Texas Instruments Inc. had designed an electronic camera in 1972 that was filmless but not digital, using instead analog electronics. After a literature search on digital imaging came up virtually empty, Sasson drew on whatever was available: an analog-to-digital converter adapted from Motorola Inc. components, a Kodak movie-camera lens and the tiny CCD chips introduced by Fairchild Semiconductor in 1973. He set about constructing the digital circuitry from scratch, using oscilloscope measurements as a guide. There were no images to look at until the entire prototype - an 8-pound (3.6-kilogram), toaster-size contraption - was assembled. In December 1975, Sasson and his chief technician persuaded a lab assistant to pose for them. The black-and-white image, captured at a resolution of .01 megapixels (10,000 pixels), took 23 seconds to record onto a digital cassette tape and another 23 seconds to read off a playback unit onto a television. Then it popped up on the screen. "You could see the silhouette of her hair," Sasson said. But her face was a blur of static. "She was less than happy with the photograph and left, saying 'You need work,"' he said. But Sasson already knew the solution: reversing a set of wires, the assistant's face was restored. In 1978, Sasson and Lloyd were issued United States Patent 4,131,919 for their digital camera. Sasson now works to protect the intellectual capital of his employer, Eastman Kodak Company
What is the meaning of voltage control device and current control device y they call like this?
In vcd, input voltage controls the output current.e.g.jfet In ccd , input current controls the output current. e.g. bjt
What technology is utilized bar code readers sense their input?
Bar code readers primarily use laser or imaging technology to sense and decode input. Laser-based scanners emit a laser beam that reflects off the barcode, while imaging scanners capture a digital image of the barcode and analyze it. Both types convert the reflected light or image data into electrical signals that are processed to extract the encoded information. Additionally, some readers may use infrared or CCD (Charge-Coupled Device) sensors for enhanced reading capabilities.
What is the difference between pir movement sensor and ir sensor?
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
Ccd camera used to focuse the ir led?
why we use LED in a hidden CCD camera?
Full form of ccd camera?
CCD = Charge Coupled Device.
How does a ccd video camera work?
In the past, cameras took still photos and videos by focusing light on film. Now, in a CCD video camera, the lens of the camera focuses light onto a small CCD sensor. CCD stands for "charge-coupled device."
What is the full form of ccd camera?
CCD stands for charge-coupled device
What is the price of a color CCD camera?
The price of a color CCD camera can vary depending on the brand and features. Most color CCD cameras are between $200 and $1200. There are a lot of factors that go into choosing one and the CCD camera with the best features tends to be the one that is the highest price.
How does a CCD camera work exactly?
A CCD camera uses a special chip which detects light photons hitting an array. This data is then converted to binary which can then be interpreted by the camera into an image.
What purpose does the CCD in your digital camera perform?
The CCD is the part of the camera that changes the light that enters the camera into a digital signal that is then saved on the memory card. You can think of it as where the film would be in a regular 35mm film camera.
What is the best camera to attach to a microscope for specimen images?
One of the best types of cameras to attach to a microscope for specimen images is a CCD camera. A CCD camera is also known as a charge coupled device camera.
What part of a camera works like a retina?
CCD Sensor (in a digital camera) = Retina
What was the first camera to use ccd?
The first camera to use a charge-coupled device (CCD) was the Bell Labs' experimental camera developed in 1969. This groundbreaking technology was later popularized by the 1975 prototype digital camera created by Steven Sasson at Eastman Kodak, which utilized a CCD sensor for image capture. The introduction of CCD technology revolutionized photography and imaging, paving the way for modern digital cameras.
