1/1.3-Inch Mobile Sensor (9.6×7.2 mm)
Sensor Formats · 7 specs
Direct Answer
The 1/1.3-Inch Sensor format (measuring approximately 9.6 × 7.2 mm with an active area of ~69.1 mm² and a 12.0 mm diagonal) is the modern flagship smartphone camera sensor format. Operating with a ~3.6× crop factor and ultra-high pixel counts (50 MP to 200 MP with 4-in-1 / 16-in-1 pixel binning), it powers flagship mobile photography.

Mobile Optical Physics & Pixel Binning
Fitting a 1/1.3-inch sensor inside an 8 mm thick smartphone chassis requires extreme computational photography and complex 7-element plastic aspherical lenses (f/1.7). By capturing at 200 MP (0.6 µm pixels) in bright daylight and merging 16 adjacent pixels into a single 2.4 µm super-pixel in low light, mobile sensors match the low-light signal-to-noise ratio of dedicated cameras.
