What does the frame rate and line rate of a CCD camera mean?

Each photocoupler unit of a CCD is called a pixel, a silicon wafer made up of rows and columns.

** (i.e., single-frame, static) has the concept of pixels but does not have the concept of frame rate and line rate.

If we talk about the relationship and influence of frame rate and line rate on CCD, we talk about the performance of CCD. If the charge on the photocoupler unit does not disappear quickly and a weak charge is retained, the color, brightness, and clarity of the next image will be affected.

Frame rate is how many images are output per second, which is often expressed by FPS, that is, frame per second. However, there are also many people who use frequency to express the frame rate, that is, the unit Hz, usually 30Hz means 30fps.

MHz generally refers to the speed of a single pixel output, because the frame rate is generally in the order of tens of magnitude, generally hundreds are considered high-speed cameras, in terms of frequency, one is tens of Hz, or hundreds of Hz.

The faster the output speed of a single pixel, the faster the frame rate, the output speed of a single pixel is generally expressed in MHz, 1MHz, which is to say, output 1024*1024 pixels per second.

It is not possible to increase the frame rate without reducing the number of pixels, you can consult the ICX274AQ manual, the readout mode is controlled by timing, there are many, basically sacrifice the number of readouts to increase the frame rate. Sedans included.

At 36MHz, 15 frames are progressive 1220 lines, while 30 frames are interlaced 528 lines (Center Scan Mode) or 305 lines (2 8-line readout mode).

Upstairs is simply misleading?,People are clearly talking about "image sensor" and "CCD", it seems that the upstairs doesn't even know what CCD is.

Re: This is really not easy to say, if the manual indicates the CCD model, it will be easy to do, just check it on the Internet.

That is, if the camera has a mechanical shutter, it must be full-frame. Conversely, it is "possible" to be interlaced.

There are two types of CCDs that do not use a mechanical shutter, one is frame shifting. One is inter-line transfer. Most of the ones used on digital cameras are transferred between lines.

There are two types of inter-line transfers: progressive and interlaced. Progressive scanning is the sequential readout of each line. Interlacing is a time-sharing readout of odd and even lines.

PAL or P system, or European standard (European standard):

1.625 horizontal scan lines per frame.

2.25 frames per second

3.Interlace (or"Staggered"), 50 fields per second

PAL TV standard, 25 frames per second, TV scanning line is 625 lines, odd field in front, even field in the back, standard digital PAL TV standard resolution is 720*576, 24 bits of color bit depth, the aspect ratio of the picture is 4:3, PAL TV standard is used in China, Europe and other countries and regions.

China's alternating current frequency is 50Hz, and the TV standard is in line with European regulations.

The black and white (EIA) and color (NTSC) standards under the US regulations are as follows:

1.525 horizontal scan lines per frame.

2.30 frames per second

3.Interlace (or"Staggered"), 60 fields per second

The black and white (CCIR) and color (PAL) standards under the European regulations are as follows:

1.625 horizontal scan lines per frame.

2.25 frames per second

3.Interlace (or"Staggered"), 50 fields per second

NTSC TV standard, frames per second (simplified to 30 frames), TV scan line is 525 lines, even field in front, odd field in the back, standard digitized NTSC TV standard resolution is 720*486, 24 bits of color bit depth, the aspect ratio of the picture is 4: TV standards are used in the United States, Japan and other countries and regions.

Frame rate, which is how many images are output per second, is often expressed in FPS, that is, frame

persecond。But there are also many people who use frequency to express the frame rate, Kai Mao and that is, the unit Hz, usually 30Hz is the meaning of 30fps.

MHz generally refers to the speed of a single pixel output, because the frame rate is generally in the order of dozens, and staring at hundreds is generally regarded as a high-speed camera, in terms of frequency, one is tens of Hz, or hundreds of Hz.

The faster the output speed of a single pixel, the faster the frame rate, the output speed of a single pixel is generally expressed in MHz, 1MHz, that is, 1024*1024 pixels per second.

It is not possible to increase the frame rate without reducing the pixels, Wuxiang can consult the ICX274AQ manual, the readout mode is controlled by timing, there are many, basically sacrificing the number of readouts to increase the frame rate.

At 36MHz, 15 frames are progressive 1220 lines, while 30 frames are interlaced read-only 528 lines (center

scanmode) or 305 lines (2 8-line
