Regarding, the issue of the size of the image of the digital camera

First, you made that right, the 400D sensor is CMOS instead of CCD.

Second, no matter what mode and resolution you shoot in (e.g. basic or fine, etc., L or M, etc.), the CMOS is %100 imaged. That is, the utilization rate of CMOS is %100. As for its size, it is up to the camera's processor to determine the sampling or interpolation algorithm.

The calculation method depends on the imaging density of the CMOS, and the algorithm is different for different image sensors.

The size depends mainly on the size of the pixels and the CCD area, but it also depends on your image quality settings and the light and dark colors of the scene, not necessarily.

It seems to be a few millimeters at 22 o'clock by 11 o'clock, which is the area of CMOS, which is about 1 2 small times the imaging area of a 135 film camera.

To put it simply, the coefficient multiplied by the phase size is the film size.

You can ask the camera dealer.

They will usually answer in detail.

I don't know much about this, so come in and learn o( o...Ha ha.

The angle of view determines the size of the image that the camera is looking at.

The image field is determined by the diameter of the lens, and the larger the diameter, the larger the image field. The lens diameter is also related to the aperture, and the larger the aperture, the larger the lens diameter. The edge of the frame and the angle formed by the lens are called the angle of view, which is related to the focal length of the lens and the imaging area of the camera.

The focal length is long, the angle of view is narrow, the focal length is short, the angle of view is wide, and the focal length is the same, and the larger the imaging area, the wider the viewing angle. For the same camera, the angle of view determines the focal length of the lens.

The focal length of the lens

is a very important indicator of the lens. Lens focal length.

The length of the subject determines the size of the subject to be imaged on the imaging medium (film, CCD, etc.), which is equivalent to the scale of the object and the image.

When shooting at the same target at the same distance, the image with a long focal length is larger, and the image with a short focal length is smaller. Depending on the application, the focal length of the camera lens varies greatly, and the sensitivity is scattered as short as a few millimeters, a dozen millimeters, and as long as several meters.

Summary. Hello dear <>

For example, a digital camera calculates the image size in the same way, and the image size of a digital camera refers to the actual size of the camera sensor, usually expressed in inches or millimeters. Larger image sizes generally provide higher image quality and better low-light performance. The image size of a full-frame camera is 36mm x 24mm, while that of an APS-C camera is about x.

The number of pixels refers to the number of pixels on a camera sensor, usually measured in megapixels. The higher the pixel count, the sharper the image captured by the camera, which allows for better cropping and upscaling. A 20 MP camera can capture images with dimensions of 5472 x 3648 pixels.

Let's give an example of how a digital camera calculates the image size

The number of pixels refers to the number of pixels on the camera sensor, usually measured in bridge megapixels. The higher the pixel count, the sharper the image captured by the camera, and the better it can be cropped and enlarged. A 20 MP camera can capture images with dimensions of 5472 x 3648 pixels.

Let's give an example of how a digital camera calculates image size, ground resolution, and altitude measurement.

A digital camera is a photographic device that uses digital technology to capture and store vertical images. They usually have an optical zoom lens that changes the focal length to adjust the size of the Tulu cave images, which allows them to shoot sharp images at close or long distances. I wish you a happy life!

Hope mine is helpful to you ha.

Dear, the full-frame camera has a picture size of 36mm x 24mm, while the APS-C camera has a picture size of about x. The pixel size of a camera is 100m, and the altitude is 100m, so the ground resolution of the machine is missing.

Summary. Kiss. Hello:

You can refer to the following: 700 1000 = about 800,000 pixels = 5 inches** (inches, millimeters 89 127); 800 1200 = about 1 million pixels = 6 inches** (4 6 inches, mm size 102 152); 1000 1400 = approx. 1.5 million pixels = 7 inches** (5 7 inches, millimeters, 127 178); 1200 1600 = about 2 million pixels = 8 inches** (6 8 inches, mm size 152 203); 1600 2000 = about 3.1 million pixels = 10 inches** (8 10 inches, mm size 203 258); 1600 2400 = about 4 million pixels = standard ** (8 12 inches, mm size 203 304); 1600 2800 = approx. 4 million pixels = width** (8 14 inches, mm size 203 356).

700 1000 = about 800,000 pixels = 5 inches ** (inches, millimeters 89 127); 800 1200 = about 1 million pixels = 6 inches** (4 6 inches, mm size 102 152); 1000 1400 = approx. 1.5 million pixels = 7 inches** (5 7 inches, millimeters, 127 178); 1200 1600 = about 2 million pixels = 8 inches** (6 8 inches, mm size 152 203); 1600 2000 = about 3.1 million pixels = 10 inches of the first film (8 10 inches, mm specifications 203 258); 1600 2400 = about 4 million pixels = standard ** (8 12 inches, mm size 203 304); 1600 2800 = about 4 million pixels = width** (8 14 inches of play, mm size 203 356).

Image Size: Also known as sensor size. The sensor size is an intrinsic parameter of the camera, and you can know the sensor size as long as you know the camera model.

For example, 4608x3456 represents the pixels of the rows and columns, and the more pixels, the better the details of the picture. But for the situation of not being the same, it is still necessary to divide.

Consideration of the situation.

First of all, if you want to carry out fine post-production, it is best to choose raw+jpeg mode, take a **, the camera will automatically generate a raw, a jpeg, wherein, raw is the last to be processed and used**, jpeg is just included, easy to preview when viewing. At this point, JPEG uses the minimal.

If it's just JPEG mode, if there are no special amplification requirements, such as just general practicality**, the first few you said are not too much, considering the time and storage occupation of the camera's generated images, personal discretion, in short, the larger the storage, the more load on the camera, but the image quality is indeed much better. However, it is usually best to use the best image quality for post-processing or enlarged printing. Moreover, when there is noise in the picture, if you want to reduce noise, you can achieve it by reducing the resolution without using the late stage of noise reduction, so that the high-level size reflects the advantages, and the resolution reduction will not make the ** too small.

The difference in pixel size is difficult to see with the naked eye, especially if the level is close, but PS will see it.

Comparing the two pictures, the top picture is 4608x3456, and the bottom picture is 1024x768 at a glance.

4608*3456 and 1024*768 refer to the resolution, which is also the pixel. Of course, 4608 x 3456 (fine) is best. And it should not be high-magnification zoom. If you want to print a large-size pictorial, you need to adjust the size of the dpi value in the properties.

Generally, you can shoot with the highest quality of your camera, such as your camera's 4608 x 3456 (fine).

4608 x 3456 mainly corresponds to the size of **, and has nothing to do with the image quality. The camera's electronic negatives and lenses are the key to image quality.

The effect will be better if you choose 4608*3456, the original image can be output greatly with high quality, and it will be better if you zoom out. And the ** of 1024*768 will become very rough if you want to be artificially amplified. FYI.

Sensor size and pixels have nothing to do Sensor size is frame-sensitive.

The landlord can go to the official website to learn more about it, in comparison, the SLR is better than the Canon. Canon EOS60D is recommended, with high configuration, clear imaging, and high cost performance, which is a new mid-level nirvana product of Canon. In addition, the compact and lightweight nature of the 60D plastic body also reduces the burden on users when carrying the camera when going out.

The size is larger, the image is clearer, brighter and higher quality.

Pixels don't matter.,Didn't you find that the camera head with a small mobile phone of a few hundred yuan is called a 1000w pixel? That's useless, it's used by manufacturers to mislead consumers.

The reason why SLR emphasizes effective pixels is because the two words effective are still reliable. Hehe, but I don't think you should pursue pixels too much, just pursue the quality of the film, no matter how high the pixel is, is it useful to be unclear or dry?
