Expanded Pixel Mode
11.7MP to 46.8MP
The IMX294 and IMX492 chips have 46.8 million 2.315um pixels, which Sony 2x2 bins on-chip to create the sensor's advertised 11.7 million 4.63um pixel array. The QHY294 Pro series camera is capable of locking and unlocking the on-chip binning to provide two readout modes. The first mode reads the sensor "locked" mode to produce 11.6mp images with 4.63um pixel size and 14 bits per pixel. The second read mode unlocks the binning to produce 46.8mp images with 2.315um pixel size at 12 bits per pixel
