description:

  The Galaxy Core GC2145 is a 2 Megapixel CMOS image sensor, for mobile

  phone camera applications and digital camera products. GC2145 incorporates a

  1616V x 1232H active pixel array, on-chip 10-bit ADC, and image signal

  processor allowing AE/AWB/interpolation/de-noise/color-conversion and

  gamma correction. Bayer RGB, RGB565 and YCbCr 4:2:2 can be provided by the

  sensor. It is programmable through an I2C interface. Image data is sent

  either through a parallel interface or through MIPI CSI-2.
