Sensor format	Sensor format
The image sensor format is the shape and size of the image sensor. It is usually expressed in inches.
1/1.72"	1/2.25"
Pixel size	Pixel size
Pixels are the basic building blocks of digital photography: they are the individual elements that capture light to compensate for your image. Pixels are usually measured in microns (μm).  Generally, the higher the sensor size, the greater the pixel size, the greater the pixel size. The more light you can take, the better your photo.
0.8 µm (micrometers)
Aperture	Aperture
The aperture is an opening or a hole through which light passes. Aperture controls the brightness of the image that travels through the lens and falls on the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
f/1.8	f/1.8
Focal Length	Focal Length
The focal length is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor.
