What is the difference between 1k x 1k and 2k x 2k CCD cameras?

Gatan, Inc: FAQ Imaging
The 2k x 2k CCD camera has an area more than 6 times that of the 1k x 1k MultiScan camera. The pixel size is 25% larger for the 2k x 2k camera, which results in better image resolution. See similar questions...

Should I consider a 1k x 1k or 2k x 2k CCD camera?

Gatan, Inc: FAQ Imaging
For holography applications, a 2k x 2k CCD camera is preferred. This is because the reconstruction of an electron hologram only uses roughly 1/4 of the image area. For a 1k x 1k camera, this means only 256 x 256 pixels. For 2k x 2k camera, the reconstruction can be as large as 512 x 512 pixels. See similar questions...

What's the difference between 2K and 4K SDRAM?

All of Memory FAQ
The SDRAM has multiple internal banks. The 16M SDRAM has 2 banks, the 64M has 4 banks. When you tell the SDRAM a ROW or COLUMN address you must also specify which BANK you are referring to. The way to do this is by the 'bank address' (BA). Herein lies the problem. For some unknown reasons, suppliers have lumped together the ROW address pins with the BANK address pins and simply refer to them as 'address' pins. See similar questions...

What is the difference between cameras with 1/4" CCD and 1/3" CCD?

Hidden Camera Surveillance Australia - Hidden Cameras, CCTV ...
This is the size of a camera sensor's active area. The smaller the dimension, the more "work" the camera will have to do to present a monitor sized picture. A 1/4" CCD will have to magnify the image more to show the image on the monitor. A 1/3" CCD will need less magnification to show the image on the monitor. A 1/3" CCD will cost more and have a better image. Both types are adequate for reaview systems. See similar questions...

What is the difference between 4K and 2K projection?

Digital Cinema FAQS
quot;4K" is the term used to describe images that have approximately 4K vertical lines. In digital cinema, a 4K image with a 2.39:1 ("scope") aspect ratio is delivered having 4096 x 1714 pixels. A 4K image with a 1.85:1 ("flat") aspect ratio is delivered having 3996 x 2160 pixels. quot;2K" is the term used to describe images that have approximately 2K vertical lines. In digital cinema, a 2K image with a 2. See similar questions...

Camera) What is the difference between CCD and CMOS?

Audio House specializes in wide variety of audio-visual cons...
The image sensor used by most digital cameras is a charge-coupled device (CCD). Some cameras use complementary metal oxide semiconductor (CMOS) technology instead. Both CCD and CMOS image sensors convert light into electrons. CCD sensors create high-quality, low-noise images. CMOS sensors are generally more susceptible to noise. Because each pixel on a CMOS sensor has several transistors located next to it, the light sensitivity of a CMOS chip is lower. See similar questions...

CCD? CIS? What's the difference?

Scanners | Frequently Asked Questions
CCD is now the standard device used in today's scanners. It stands for Charge Coupled Device and it works like this: The device accepts light, converts it to electrical chargers that are then stored and manipulated into digital images. CIS on the other hand used to be the standard, but it has been mostly replaced by CCD. CIS based scanners are heavier and slower than their CCD brethren. See similar questions...

What is the difference between AMI and X-ray?

Sonoscan Frequently Asked Questions
AMI and x-ray are complementary techniques that are both frequently found in the same laboratories. They have important differences with regards to what they reveal in a sample. X-rays can be used to see inside a sample based upon material density differences. Dense materials are more opaque to x-radiation and penetration is more limited through metals compared with ceramics or polymers. See similar questions...

Do The Imaging Source CCD cameras run on Mac OS?

Astronomy Cameras and Telescope Cameras FAQs
The Imaging Source manufacturers FireWire cameras. We do not offer any individual consulting at system level. The following recommendations are only general in nature. The responsibility for the correct usage of the camera lies in the hands of the on-site engineer. The Imaging Source does not take any responsibility for errors, loss of data or other damages that are the result of these recommendations. See similar questions...

Do I need a power supply for The Imaging Source FireWire CCD cameras?

Astronomy Cameras and Telescope Cameras FAQs
No. All FireWire CCD cameras, manufactured by The Imaging Source get their power via the FireWire interface. See similar questions...

How can The Imaging Source FireWire astro CCD cameras be mounted on telescopes?

Astronomy Cameras and Telescope Cameras FAQs
All The Imaging Source FireWire astro CCD cameras have standard a C-Mount. You can purchase adapters for various telescope mounts at your local telescope accessory store. See similar questions...

Do The Imaging Source color CCD cameras output raw image data?

Astronomy Cameras and Telescope Cameras FAQs
Y800: Camera based color interpolation is turned off and the raw color data stream from the CCD is outputted in the monochrome format Y800. The camera control software IC Capture.AS displays color images in their raw form. Therefore, they appear to be monochrome at first sight. This mode is not suited to visualization applications. However, should you wish to capture an uncompressed AVI file, you should use this mode. BY8: the structure of this format is equivalent to that of the format Y800. See similar questions...

What are the common sizes of CCD imager in CCTV cameras?

CCTV LENS DEPOT with frequently asked questions and answers
It is 1/3", 1/2" There is also new format coming up and that is 1/4" while 2/3" and 1" are disappearing. Yes, but you can also take bigger lenses for smaller camera imager. Example: 1/3" camera will take 1/2" and 2/3" lenses. 1/2" camera will also take 2/3" size lens. See similar questions...

What sort of video based CCD cameras does MCID Elite support?

MCID Elite - FAQ: Imaging Research Inc.
MCID Elite will support any monochrome video camera that conforms to either the RS170 (North American) or CCIR (European) video standard. For color video based cameras, the camera has to be capable of outputting a video signal in the RGB format (separate outputs for the red, green and blue channels). MCID Elite has additional support (controls camera integration) for the following video based CCD cameras: See similar questions...

What types of digital CCD cameras does MCID Elite support?

MCID Elite - FAQ: Imaging Research Inc.
Roper Scientific CoolSNAP family of cameras (Both monochrome and color and Cascade): http://www.photomet.com MCID Elite can also accept images from almost any device, which generates binary file formats. A file format editor is included in the program to allow you to create templates to read in any binary image. See similar questions...

Why is there mismatch in the montage image acquired from wide-angle MultiScan CCD cameras?

Gatan, Inc: FAQ Imaging
It is common to observe mismatch in montage images acquired from a wide-angle CCD camera. The mismatch comes from the common distortions in a TEM column when large-field-of-view images are acquired. Such distortions increase rapidly as the third power to the radial distance. Typically the distortion is less than 1% at the edge of the film. Since the Gatan wide-angle CCD camera has a field of view much larger than film (6 times more), it is inevitable to observe distortions from the TEM. See similar questions...

What are the main differences between the wide-angle and bottom mount MultiScan CCD cameras?

Gatan, Inc: FAQ Imaging
Field of view and effective magnifications. Wide-angle cameras have a large field of view (about 6 times larger than that of film), but have an effective magnification of 20-30% of that of film. On the other hand, a bottom mount camera has a field of view of only 10%, but effective magnification of about 130-150% of that of film. See similar questions...

Can I do TEM Tuning and DigitalMontage with MultiScan CCD cameras?

Gatan, Inc: FAQ Imaging
Yes, absolutely. However, mismatch may be observed in montage images acquired from wide-angle cameras, i.e. MS600W and MS600CW. No. Gatan does not offer any sort of upgrade. The hardware components have changed so much in the past, it is almost impossible to upgrade them to the current platform. Gatan recommends a trade-in option for the SSC cameras.
