I have a linear and color ccd (RGB) with low sensitivity or response, according to it's data sheet. My work is based on FPGA and VHDL. analog output of this ccd sensor ,observed on oscilloscope screen, has below typical shape. but it acts reversely. that is, the differences between the reference level and (...)
Unfortunately, if it has the pattern in the SDI stream it means it is coming from the ccd or something near to it in the circuit. There is remote possibility it is noise on the supply line but that would tend to show more on the composite output than the SDI output. You really need a schematic and a good oscilloscope to investigate this fault but
Hi there! I want to use the KAF1001-ccd for image processing ( ). I have some understanding problems with the clocking/timing of V1 and V2 according to set the integration time. In the datasheet on Page4 it is written: "Referring to the timing diagram, integration of charge is perfo
Hi to all First sorry for bad english I have a barcode scanner is zebex z3100 Link I need learn that barcode reader's default settings because that is not standart I mean barcode equipmet connection side have 5 Pin DIN connector but only 3 pin soldered red,black and white cable conne
At the header of the datasheet(you can google it, I wasn't sure if a datasheet counts as an ebook), it says 600DPI sensor. However, it has 7500 pixels per line(7500*3 for RGB technically), and sensors are almost 70mm long. How does this translates to 600DPI? By my calculation, 7500pix/70mm = 107DPmm = 2721.4 DPI. I've never worked with linear
This solution has many problems. One solution might be to use a black hole for laser beam with white reflector around hole to view diffusion of smoke particles. Then using a PD on a portion of beam centre for reference on peak level behind hole and then a simple Lambertian PD aimed at reflector to view diffused smoke pattern intensity, one can est
Is it possible to do the similar thing for InGaAs image sensor? I notice each InGaAs pixel is followed by a transimpedance amplifer. Can they do the ccd implementatation where they transfer charge from this pixel to next pixel? instead of using an amplifier for each pixel, for noise reduction reasons? and use floating diffusion as the output. Th

I'm looking to create an underwater ROV. To that end, I'm investigating options when it comes to video and am currently reading posts on this subject to determine what I can do. One solution that I think might work is a ccd camera -> balun -> serial/Ethernet -> balun -> usb connector -> pc -> OpenCV software As I have no w
Great project! Many years ago I worked on an early ccd spectrometer for Laser Raman and ccds had really just become available, We used one designed for long exposures for space exploration, the key to it's low noise was cooling, it used liquid nitrogen via a heat exchanger - great fun. A Peltier cooled one using a stack of 3 peltiers or (...)
Hi, I am currently working on a project in which I have to interface ccd camera ATIK314L+ with an embedded board. Camera ATIK314L+ is provided Cypress FX2 USB drivers support.

hello, am new to this field and currently doing a project on refractometer ,can anyone tell me how to relate a shadow line of an ccd image and refractive index. I got the shadow line from the ccd output,waiting for your valuable comments,thanks in advance
Hello all, I'll be attempting to interface with a ccd, and I've been putting some thought into the memory requirements. I assume I'll be using a 14-bit ADC, and the ccd is linear with 7500 pixels. Considering the data will be stored in 16-bit lengths, about 15kB of memory is needed per line. I'll further assume many (...)
That sounds like a very high resolution. Usually, such a high res is not needed. At lower res, check The Imaging Source for GigE cams up to 100fps for a few hundred $. If you need to know the position at a certain time, there is another trick; that is to leave the ccd integrating, and to have complete darkness, and have a pulse of very (...)
Hello, I'm a newbie to ccd interface and I want to know how to integrate ccd interface with interfaces such as avr? Thanks.
I use 2 bipolor transistors to driver the ccd(charge coupled device) reset gate. 80931 The 2 bipolor transistors are 5GHz from NXP. the datasheet give the DC current of 100mA of collector. however, how about the max transent current? Is my circuit right? Any idea is welcome, and thanks in advance!
Which ccd image sensor? - link to datasheet maybe? Which PC? - a normal desktop PC?
Hii, This is my first post.. I am currently working with Laser Triangulation method. The reflected laser light is received in ccd. I want to measure an angle of received laser light with respect to ccd axes. I found that ccd converts received energy into digital data... So, i want to know that How to interface this ccd (...)
It doesn't look like an IR sensor, it appears to ne an image sensor (ccd) as HTA says. A lens would focus an image on the surface of the chip and by clocking the various pins it would serially read the pixels. I don't recognise that particular one but it is typical of the sensors used in older CCTV cameras. Brian.
Hello. I'm trying to read ILX533K linear ccd with an atmega, and had no luck so far. The frequency used is about 20kHz (ADC limited). Datasheet specifies timing requirements for typical of 1MHz, but does not specify any lower limits on it. I'm reading every 4th pixel, inserting an equivalent delay for the rest. Connected as per datasheet rec
I am working on one project. In which I have ccd image sensor (Sony's ICX254AL ) and its output is connected to Analog Front End (TI's VSP2562). The output of Analog Front End (AFE) is 12 Bit Digital data at the rate of 9 MHz. I am thinking to use NI's PCIe 6535 as a data acquisition device to get those digital data in to computer using a MATLAB. N

I have a 256 pixel linear ccd. I need to detect edges, i need a fast algorithm to for edge detection with minimum number of calculations. My processor is not powerfull enough. What is "not powerful enough" in terms of MIPS, MHz, anything? What accuracy do you need? Correct and slow way is to calculate correlati
Hi All, I am doing my project based on fpga, I have a board which has 32 bit Axis Etrax FS processor and Spartan 3E fpga. My project outline is -A ccd camera has to be connected to this board and hence it will store the streaming images in its memory, those image files has to be programmed to fpga, then the images has to be displayed on (...)
Hello, I am building a camera with ccd sensor, and here are some things I don?t understand: ccds I saw have more line than the lines used for their dedicated format: 492 or 494 active lines for ccds labelled NTSC (480 displayed lines). and it is the same for PAL (582 active (...)
Hi Scanman, Typically CMOS Image sensors do CDS ( correlated double sampling ) on-chip. So a opposed to ccd there is no need to do CDS off-chip. In CMOS sensors CDS is done to reduce the pixel KTC noise of the pixel and reduce FPN of the pixel. Depending on the CMOS Image sensor one still need to do off-chip channel FPN correction i.e. s
Hi everyone; I need to program Kodak KLI4104 ccd camera, operating at 5Mhz. However, i couldn't understand the timing specifications at all. Please help, the specification pdf is uploaded Thanks all.

I'm working on embedded image processing project using Altera DE2 board, which uses ADV7181 for TV decoding. My problem, is that I'm stuck at Image Acquisition stage, I've used the DE2 default TV decoder program, which comes with its CD, and attached a ccd camera to the CVBS input (video input) of the board but no results yielded when I connect
G'Day, I have a requirement to send an SMS to some form of SMS controller. The controller would need to then trigger a capture from a ccd image sensor, package the image and then send the image as SMS/MMS to predetermined numbers. Cant use mobile phones, PDA's etc due to reliabilty of the system. I can get the part of sending an SMS message to
Hello everyone, I am trying to build a driver circuit for a ccd. The input is a clock signal from 0 to 3.3v and the output needed is from +15 to -9. I tried to simulate in Multisim with a simple Push pull BJT amplifier. I have attached the circuit screenshot. I know that the simulation is ideal and the input clock cannot (...)
Thanks for the feedback. This is actually a new design. It's a multi component solution that takes ccd and formats it to s-video. There's a 6dB amp in after the final amp. I kept thinking the same thing. It must be some anomaly created after the conversion to s-vid format... after ( or right before) the final amps.
Does anybody have an idea or links how to measure light level by using BW ccd camera and MCU?
I am thinking to build a scanning back for large format cameras, something similar with BetterLight products. For now I am just studying the possibilities and evaluate the costs. Can anyone recommend linear ccd sensors suitable for such a task? Key features should be: -resolution higher than 6000 lines/color -must have color outputs, R/G/B I am
I want to interface my digital camera with a project I'm working on. From best I can tell so far, USB has several device classes and the camera would need the Image class. Most of the USB IC's from Maxim, FTID, etc seem to only support HID, ccd, and Mass Storage. Anyone know of an IC that would work with teh camera or do I need to (...)
Hi, I am trying to obtain phase and amplitude images by using Fresnel tranform. In my matlab program, I call the saved image (acquired by a ccd), use fft and ifft to recontruct the image field (x2) at different z distance values. I create the amplitude image by using command Intensity = abs(X).^2; where (...)
How to consider the noise level issue when design ccd camera? One requirement of the power supply for the ccd camera is voltage accuracy must be in 1% under -45C degree to + 85 C degree. Should I use the commercial switching power supply chip or use the discrete components to build this switching power supply? Thanks.
