What is the highest pixel of the camera?

Question 1: What is the highest pixel of the camera now? How much is enough for ordinary people? Up to now, Hasselblad H6d- 100c, 1 100 million pixels are the highest pixels in the household field; In the professional field, the highest pixel of the camera is the Swiss Seitz camera, with 65.438+0.6 billion pixels; In the field of national defense science and technology, the Pan-STARRS astronomical camera system of MIT has the highest pixel, with 65.438+0.4 billion pixels; Of course, this does not include cameras in the military field with high security level;

2. Pixel is absolutely proportional to resolution. The higher the pixel, the higher the resolution, which means the larger the size that can be enlarged.

3. Pixels are directly proportional to sharpness. The clarity of digital imaging is closely related to the signal-to-noise ratio of sensors, lens quality and image processor technology. As far as pixels are concerned, pixels are photosensitive spots built on sensors. On the premise of the same pixels, the larger the sensor area, the smaller the pixels per inch, the larger the area of a single pixel, the better the photosensitive performance, the better the signal-to-noise ratio index and the better the definition. On the contrary, the definition will be worse. Therefore, the higher the pixel on the sensor, the lower the density and the higher the definition, while the higher the pixel on the sensor but the higher the density, the worse the definition, which is relative;

4. "How much is enough for the average person?" Everyone's standards are different.

First, different magnifications require different pixels. For example, a large commercial photo (above 5MX5M) needs at least 20 million pixels to support, while a 7-inch photo at home has more than 4 million pixels, and the extra pixels cannot be developed;

Second, different carriers need different pixels to display photos. There are generally three kinds of digital display carriers at home, one is computer monitor, the other is digital photo frame, and the third is TV. Among the popular home display carriers, 1920X 1080P display needs more than 2 million pixels to display photos perfectly. (One photosensitive element on the display corresponds to one pixel. 1080P has only over 2 million photosensitive elements, and only 20,000 can be displayed. 3840X2 160P 4K display needs more than 8 million pixels to display photos perfectly; With the development of the future, the emergence of 6K, 8K or even higher resolution displays requires higher pixels.

Thirdly, because the photos taken may be artificially cropped for some reason, the pixels needed are different. Assuming that the information of the photos is evenly distributed in the photos (actually, it is uneven, with more information in the center), half of the photos with16 million pixels are cut off, and the remaining half can still be perfectly displayed on the 4K display; Assuming that the photos taken are full-body panoramic photos of people, and only 10% of the pictures are intercepted and watched on the 4K display, the photos taken by Hasselblad H4D60 camera with the second highest pixel are still insufficient and cannot be displayed perfectly;

5. Because the sensor area is generally fixed, among household cameras, the highest end is the medium-frame camera, the high-end is the full-frame camera, and there are more half-frame cameras. Others include 4/3 inch sensors, 1 inch sensors, and the lowest 1/2.3 inch sensors. The ratio of sensor area to pixel number must be considered, which is the signal-to-noise ratio theory in digital imaging. On the basis of ensuring the number of pixels necessary to display photos or enlarge the size, the higher the signal-to-noise ratio (the smaller the number of pixels per inch), the better the definition, and the higher the total number of pixels, the larger the enlargement size. How many pixels are enough can be determined according to your own needs;

6. "How much is enough for ordinary people?" Personally, as long as it is not easy to cut off half of the picture,160000 pixels is more than enough for photos of 4K display devices.

Question 2: What is the highest pixel of a digital camera now? What is the camera with the highest pixel on the earth? The camera with the highest pixel on the earth is the Pan-STARRS astronomical camera system of MIT, with 65.438+0.4 billion pixels!

Of course, there is obviously no way for such a high-pixel camera to be used for civilian use. Pan-STARRS (Panoramic Search Telescope and Rapid Response System) is mainly used for scientific research such as astrophotography and detecting asteroids that may hit the earth. And relying on the ultra-high pixels of 65.438+0.4 billion, we can shoot planets that are 6.5438+0 million times weaker than human eyes. Structurally, Pan-STARRS consists of 60 CCDs, of which 1 CCD is dedicated to tracking the moving stars when shooting.

The giant 6x 17 digital camera of Swiss Seitz Company can achieve this effect. This camera will go on sale early next year, with a price of 27,000 to 29,000 euros.

6x 17 can take photos with 65438+600 million pixels, with a resolution of 2 1250X7500 and a color depth of 48bit. Because of the digital back technology similar to scanning, it takes 1 second to shoot the highest resolution image, so the hand like that in the photo can't be shot. The maximum shooting speed of this camera is 1/20000 seconds. Large-format lenses from famous factories such as Schneider, Rodstock, Lin Hafu and Fuji can be used. Because an uncompressed picture with the maximum resolution is 950MB, the storage system of this camera directly uses an Apple Mac Mini, which is connected through a Gigabit network.

6x 17 is definitely not for amateur customers. For professional photographers, it is definitely a sharp weapon. Seitz will exhibit 6x 17 in Photokina next week.

Question 3: How many pixels is the highest for a camera? The camera with the highest pixel on the earth is the Pan-STARRS astronomical camera system of MIT, with 65.438+0.4 billion pixels.

Among the cameras that ordinary people can afford and use well, the highest pixels are Canon 5DS and 5DR, with 50.6 million pixels.

Question 4: What is the highest pixel of the camera? Is it 5.4MB or 5.4MP pixels? I don't fully understand what you mean.

However, in popular science, the quality of taking pictures is not determined by simple indicators such as the number of pixels, the size of the sensor frame (that is, the larger the chip area receiving light, the better) and the optical quality of the lens (lens material, coating and lens group structure). And the lens aperture, aperture size, image field area, etc. ), graphics processor, metering, focusing system and so on can ensure good imaging.

Pixel It is an index that merchants use to refer to the quantification of consumer goods when selling, and it has no absolute reference value.

Ordinary consumers rarely come into contact with high-pixel environments, such as large-format output printing and large-area cutting.

At present, the pixel number of consumer computers is about 8 million-16 million pixels, which is not subdivided. Machines under 800 are mainly mobile phones. The iPhone's 8 megapixels are very practical.

The number of pixels of entry-level professional machines is about1200-180,000 pixels, and the lower limit of attention is120,000 pixels. That is to say, there are also professional machines with relatively low pixels, but their uses and functions are different.

SLR camera is the most mainstream professional camera system at present, and the pixel range of the entry machine is the same as above.

The pixel number of professional SLR is about1800-36 million. Note that the upper limit is 36 million pixels. Only a few models, such as Nikon's flagship D800, have 36.3 million effective pixels.

The taller ones have numbers on the back. Freescale digital back Freescale IQ280 has 80 million effective pixels, worth 300,000. .

That's about it.

Question 5: What is the highest pixel of a digital camera? Kodak and Freescale both have 39-megapixel digital backs, and the price is about 250,000! Ordinary digital SLR Canon machine emperor is160000, mamia ZD is 22 million!

Question 6: What is the highest pixel of a digital camera now? The camera with the highest pixel found at present is a camera on a satellite scrapped by an American local tyrant in the United States a few years ago, which claims to be 4 billion pixels and actually has 3.8 billion pixels. The civilian camera with the highest number of pixels is1600,000 pixels. The machine is Seitz 6x 17 digital; . The highest pixel of mass production camera should be Freescale IQ 2.808 million pixels; Then there is Hasselblad H4D, with 60 million pixels; Hasselblad H5D, H3D and Pentax 645Z are all 50 million pixels; Then Nokia 808,465,438+0 million pixels; Nokia lumia 1020, Pentax 645D are all 40 million pixels; Nikon D800 series, 36 million pixels. These are the representatives of ultra-high pixel machines, and the two mobile phones have the largest pixels per inch.

Question 7: What is the highest pixel of the camera? 20 15 in the SLR, the highest pixel is Canon's 5DS series, reaching 50 million pixels.

Of course, the price is also very high.

Hope to adopt.

Question 8: What is the maximum number of pixels in a camera at present? The camera with the highest pixel found at present is a camera on a satellite scrapped by a local tyrant in the United States a few years ago, which claims to be 4 billion pixels and actually has 3.8 billion pixels. The civilian camera with the highest number of pixels is1600,000 pixels. The machine is Seitz 6x 17 digital; . The highest pixel of mass production camera should be Freescale IQ 2.808 million pixels; Then there is Hasselblad H4D, with 60 million pixels; Hasselblad H5D, H3D and Pentax 645Z are all 50 million pixels; Then Nokia 808,465,438+0 million pixels; Nokia lumia 1020, Pentax 645D are all 40 million pixels; Nikon D800 series, 36 million pixels. These are the representatives of ultra-high pixel machines, and the two mobile phones have the largest pixels per inch.

Question 9: How many megapixels does the camera with the highest pixel have? Forget NASA's $4 billion. According to the different lenses used, the pixels of Roundshot D3 of the highest commercial Saize Company are also different, and the 24mm lens can reach 65.438+42 million pixels. 250mm lens, the number of pixels can reach 65.438+0.48 billion. 80mm lens, the number of pixels can reach 470 million.

The resolution of photos taken by this camera can reach 7500*2 1250 pixels. The ISO range of a circular D3 camera is 500-10000, and the shutter speed can reach 1/20000. The transmission rate of phase ingot is 300MB per second.
