This means that changing the digital gain setting does not require any of the offset correction settings to be updated. 7.7.3 Compression Figure 115: Compression Registers Register Name Bank Addr Bits Description COMPRESS_EN 0 65 [0:0] 0: Disable digital compression 1: Enable digital compression COMPRESS_KNEEPOINT 0 66 [12:0] Threshold above which data is compressed COMPRESS_RATIO 0 68 [1:0] Compression number 0: Ratio 2 1: Ratio 4 2: Ratio 8 3: Ratio 16 OUTP_BITMODE 0 7 [1:0] Pixel data width of the output channels 0: Unused 1: 10-bit data 2: 12-bit data The sensor can digitally compress the output pixel data as shown in the figure below. Figure 116: Digital Data Compression Pixel values below the knee point (Pk) are not compressed (1:1 mapping); pixel values above the knee point are compressed with a ratio of 1 over COMPRESS_RATIO. At the receiver side, the original pixel levels can be reconstructed (except for the LSB bits for pixels above Pk). After limiting the output level to a lower number of bits that the input level, the framerate can be increased by trimming the width of the output data channels, with OUTP_BITMODE. Input Level Output Level Pk 1:1 1:2 1:4 1:8 Pk |
