Why are digital cameras so low in pixels but so expensive?

Digital cameras shoot dynamic video, and 800,000 pixels can realize visual appreciation, which can meet the quality requirements of ordinary cameras. If it is too big, it is also a waste. At present, 800,000 pixels is very close to the level of DVD, so it is not unclear.

Digital cameras shoot static pictures, which need to accommodate more picture information within a certain size range, so the requirements for pixels are higher. But as a general demand, 8 million pixels is enough, and it will be wasted if it is higher.

Now some digital cameras have a camera function, which is only 2 million pixels, and the effect is not as good as that of digital cameras.

The so-called profession has specialization, and each has its own field characteristics.
