High Dynamic Range
12- to 10-Bit ADC Companding Chart
The MT9V022 pixel light response can be optionally configured to achieve intra-scene
dynamic range as high as 100dB. High dynamic range is achieved by controlling the
slopes of a three-segment, piecewise, linear pixel response, as illustrated in Figure 7. The
slope of the three segments can be programmed via the serial interface.
By default, the MT9V022 ADC has a linear response with 10-bit resolution. The ADC can
also be configured to have a 12- to 10-bit companding response, as illustrated in
Figure 7. This mode allows higher ADC resolution (12 bits) for low-level signals (shadow
details) and lower ADC resolution (9 bits) for high-level signals (highlight details. )
