Sensor size is generally a good indicator of the quality of the camera. Sensors can vary greatly in size. As a general rule, the bigger the sensor, the better the image quality.
Actual sensor size
Bigger sensors are more effective because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older.
Pixel pitch. Pixel pitch tells you the distance from the center of one pixel photosite to the center of the next. It tells you how close the pixels are to each other. The bigger the pixel pitch, the further apart they are and the bigger each pixel is.
Bigger pixels tend to have better signal to noise ratio and greater dynamic range.
Pixel area. Pixel or photosite area affects how much light per pixel can be gathered. The larger it is the more light can be collected by a single pixel.
Larger pixels have the potential to collect more photons, resulting in greater dynamic range, while smaller pixels provide higher resolutions more detail for a given sensor size. Relative pixel sizes:. Pixel area difference: 0. Pixel density.

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. Higher pixel density means smaller pixels and lower pixel density means larger pixels. Canon IXY F has approx.

Surface area Surface area is calculated by multiplying the width and the height of a sensor. Sensor resolution Sensor resolution is calculated from sensor size and effective megapixels.
It's slightly higher than maximum not interpolated image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula.
For sake of simplicity, we're going to calculate it in 3 stages.
First we need to find the ratio between horizontal and vertical length by dividing the former with the latter aspect ratio. It's usually 1.
