Is a digital camera with higher pixels better?

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

The photo size setting of digital cameras mainly depends on whether the pixels meet the requirements. Pixels are the most important indicator for measuring digital cameras. Pixels refer to the resolution of a digital camera.

Mainstream SLR digital cameras have more than 20 million pixels, but 10 million pixels are enough for ordinary photography and home use, because the resolution of the monitor we use is limited, generally 1366×768 to 1920×1200, so If a picture with too high pixels is displayed at a resolution, the picture will be compressed to the size of the current screen. At this time, some pictures will be too sharp and distorted.

Extended information:

In the market, some merchants will indicate "up to XXX pixels through hardware interpolation". This is the same principle, except that the image quality and sensitivity are different In terms of resolution, the clarity of pictures taken with the maximum pixels is not as sharp as those taken with the effective pixels.

Maximum pixels also directly refer to the pixels of CCD/CMOS photosensitive devices. In order to increase sales, some businesses only advertise the maximum pixels of digital cameras. When setting the picture resolution of digital cameras, there are indeed shooting The highest pixel resolution picture. However, users should be aware that this is a value obtained through the internal calculation of the digital camera. When the picture is printed, the loss of image quality will be very obvious.
