How high are the pixels of a digital camera?

Digital camera photo size setting:? 640×480, 1024×768, 1600 × 1200, 2048× 1536 are all acceptable.

The photo size setting of digital camera mainly depends on whether the pixel meets the requirements, and the pixel is the most important index to measure the digital camera. Pixel refers to the resolution of a digital camera.

Mainstream SLR digital cameras have more than 20 million pixels, but1million pixels is enough for ordinary photography and home use, because the resolution of the display we use is limited, generally from 1366×768 to 1920× 1200. If a picture with too many pixels is displayed at this resolution, the picture will be compressed to the size of the current screen.

Extended data:

Some merchants in the market will mark "XXX pixels can be realized by hardware interpolation", which is the same principle, but from the perspective of image quality and sensitivity, photos taken with the largest pixel are not as clear as those taken with effective pixels.

The largest pixel also refers directly to the pixel of CCD/CMOS photosensitive device. In order to increase sales, some businesses only promote the maximum pixel of digital cameras. When setting the picture resolution of digital cameras, they do take pictures with the highest pixel resolution. However, users should be aware that this is the value obtained through internal calculation of digital camera, and the loss of image quality will be very obvious when printing pictures.
