In omap35x camera ISP we need to give Gamma Table for RGB in the PREVIEW engine.In the EVM BSP one sample lookup table is there for Red,Blue and Green.It contains 1024 values.
Usually gamma LUT table is generated using the formula
gamma_corrected_image = image ^ (gamma_value);
Using this we can generate a LUT of 256 values.
But For OMAP35x camera ISP we need to give LUT of 1024 values.
How can I convert this gamma table of 256 values which is calculated using above formula into 1024 values?
