What determines the sharpness of a photo? Pixels? The higher the pixel, the sharper the photo.
The resolution and pixels determine the clarity of the photo. The larger the pixel, the higher the resolution and the clearer the photo, and the larger the output photo size.
in most digital cameras, you can choose different resolutions to take pictures. The higher the pixels of a digital camera, the greater the resolution of its picture. The resolution is directly related to the pixels of the image.
a picture with a resolution of 64 x 48 has 37,2 pixels, which is what we often call 3, pixels, while a picture with a resolution of 16 x 12 has 2 million pixels. In this way, we know that the resolution represents the unit of the number of points in the length and width of the picture.
the highest resolution of a digital camera is the area where it can take the largest picture. Technically speaking, a digital camera can produce the most pictures per inch of an image, usually in dpi (Dot per inch in English). The larger the resolution, the larger the area of the picture.
Extended data
Resolution:
Resolution determines the fineness of bitmap image details.
in general, the higher the resolution of an image, the more pixels it contains, the clearer the image and the better the printing quality. At the same time, it will also increase the storage space occupied by files.
the resolution is directly related to the pixels of the image. Let's calculate that a picture with a resolution of 64 x 48 has a resolution of 37,2 pixels, which is what we often call 3, pixels, while a picture with a resolution of 16 x 12 has 2 million pixels.
In this way, we know that the two figures of the resolution represent the units of the number of points occupied by the picture in length and width. The aspect ratio of a digital picture is usually 4: 3. Resolution is one of the important parameters for LCD and traditional CRT displays.
the resolution supported by the traditional CRT display is more flexible, while the pixel spacing of LCD is fixed, so it does not support as many display modes as CRT. The best resolution of LCD, also called the maximum resolution, can only show the best image under this resolution.
Pixel:
Pixel is the most important indicator to measure a digital camera. Pixel refers to the resolution of a digital camera.
it is determined by the number of photosensitive elements on the photoelectric sensor in the camera, and one photosensitive element corresponds to one pixel. Therefore, the larger the pixel, the more photosensitive elements there are, and the greater the corresponding cost. The image quality of digital cameras is partly determined by pixels, and it is meaningless to simply compare them with pixels if they are larger than a certain size.
The pixel of mainstream SLR digital cameras is about 1 million, but 5 million pixels is enough for ordinary photography and home use, because the resolution of the monitor we use is limited, generally from 124×768 to 192×12. If the picture with too high pixel is displayed with such a resolution, the picture will be compressed to the size of the current screen, and some pictures will be distorted due to too high sharpness.
the imaging quality mainly depends on the lens of the camera, the size and quality of the photosensitive element. The larger the pixel, the greater the resolution of the photo and the larger the printable size. However, early digital cameras were all below 1 million pixels. Since the second half of 1999, 2 million pixel products have gradually become the mainstream of the market. (mobile phones are generally 2 million pixels, and ordinary digital cameras are generally above 3 million pixels. )
