state	Input	ISP firmware status When state is HI_ISP_FMW_STATE_FREEZE, some algorithms of the ISP firmware are frozen, and the sensor registers are not configured any more and their values before freezing are retained. The algorithms include the 3A algorithm, sharpen algorithm, dynamic range compression (DRC) algorithm, crosstalk removal algorithm, NR algorithm, dehazing algorithm, demosaic algorithm, black level algorithm, fixed pattern noise (FPN) removal algorithm, and WDR algorithm. If state is HI_ISP_FMW_STATE_RUN, the ISP firmware runs properly.

ISP firmware status

When state is HI_ISP_FMW_STATE_FREEZE, some algorithms of the ISP firmware are frozen, and the sensor registers are not configured any more and their values before freezing are retained. The algorithms include the 3A algorithm, sharpen algorithm, dynamic range compression (DRC) algorithm, crosstalk removal algorithm, NR algorithm, dehazing algorithm, demosaic algorithm, black level algorithm, fixed pattern noise (FPN) removal algorithm, and WDR algorithm.
If state is HI_ISP_FMW_STATE_RUN, the ISP firmware runs properly.
