Figure 114 :

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.

Attention

In different scenarios, depending OUTP_BITMODE, other static register uploads are required. Refer

to section Set Output Data Width in section 7.4.3 for detailed uploads.

Description

STAT_NROF_HIST

[2:0]

0: No image statistics are output

1: Send out 1 histogram: all color channels only

2: Send out 2 histograms: all colors + ReCe

3: Send out 3 histograms: all colors + ReCe + ReCo

4: Send out 4 histograms: all colors + ReCe + ReCo + RoCe

5: Send out 5 histograms: all colors + ReCe + ReCo + RoCe + RoCo

STAT_FREQ

[7:0]

Inverse proportional to the number of pixels used in the statistics

gathering. Minimal value is the number of physical output channels

per side on the sensor, i.e. 8
