The size of the sensor indicates the physical dimensions of the light-sensitive chip, which is a key component of the camera and is used to capture light and convert it into a digital image. A larger sensor has the ability to capture more light, which positively affects the resulting quality of photos and videos. This is especially evident in lower light conditions, such as dusk, where the larger sensor produces an image with less digital noise, which is unwanted grain in the image. In addition, a larger sensor allows for a wider dynamic range, i.e. better rendering of details in overly bright and dark parts of the scene at the same time. Size is usually given in inches, for example "1/2.3 inch" or "1 inch", with the smaller the number in the denominator of the fraction, the larger the sensor.
