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
FD where is charge stored for readout in photogate pixel sensors. Name same from ccd output amplifier stage. photo carriers pushed to FD node at readout. if helped push button!
Does anyone have worked with ccd Linear Image Sensor? I have a problem for reading from ilx511. ilx511 has 2048 pixels.According to page 3 and 4, every pixels has a value and the its output is pin of 1. How can read from any pixel? Please help me... - - - Updated - - - It means How I can reach to extent o
I have a Bosch ccd camera installed on the home security through DVR. The camera is installed outside to monitor the in and out of the main entrance. The camera started flickering (display on LCD appears and disappears periodically). What can be the reason for this and how I can rectify that. Is there any possibility that (...)
I have got a 27 x dsp color video camera (ccd) which I want to injstall on the robotic arm. It is 12 DC operated and has some connections for zoom and focus inputs / control alongwith the power connector. It also has manual zoom and focus control at the back panel. I want to implement controls of camera zoom (...)
Hi everyone I am going to design a system which is going to employ a ccd, a logic circuit, a micro controller, as well as an analog circuit, and I want to simulate my design. I need a library for ccd sensors in Proteus, Pspice, or any other simulator programs. Does any one know how I can find it? if such does not exist does anyone have any (...)
anyone here familiar with terasic d5m camera? i am using this development kit from altera to interface with my board. i have a problem understanding on how the pixels enter is written when pausing the camera since i only need the output image. i understand that the ccd capture module is responsible for starting or capturing the image (...)
Hi, I have ccd and Amplifier that are connected by a Flexi Cable with 37 microType-pin Connector. The EM target is to model the system with CST CABLE STUDIO. ccd output impedance is 500 ohm Amplifier External Load is 1oKohm or higher Which is the impedance of each in-pin?Is 500ohm or 500/37 ohm? and for the (...)
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. I successfully completed interfacing of camera with windows7 based PC using the ArtemisSDK Visual studio application provided by ATIK. and, now I want to develop embe
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.
