Camera 330

The larger the sensor size, the larger the photosensitive area and the better the imaging effect. 11.8-inch 3-megapixel camera is usually better than 1/2.7-inch 4-megapixel camera (the light-sensitive area of the latter is only 55% of the former). It is good to increase the number of sensor pixels with the same size, but it will also lead to a decrease in the photosensitive area of a single pixel, which may lead to underexposure. Digital cameras with larger sensors are also expensive. The size of the photosensitive device directly affects the volume and weight of the digital camera. Ultra-thin and ultra-light digital cameras generally have smaller sensor sizes, and the more professional digital cameras have larger sensor sizes. So 1/3.2 is good.
