Enable Gamma Correction
^^^^^^^^^^^^^^^^^^^^^^^
The human visual system is non-linearly sensitive to the physical luminance. Adding gamma correction to the ISP pipeline to transforms RGB coordinates into a space in which coordinates are proportional to subjective brightness.
The driver provides a helper API :cpp:func:`esp_isp_gamma_fill_curve_points` to fill :cpp:type:`isp_gamma_curve_points_t`, which is a group of points used to describe the gamma correction curve. Or you can manually declare the points as your desired 'gamma' correction curve. Each R / G / B component can have its own gamma correction curve, you can set the configuration by calling :cpp:func:`esp_isp_gamma_configure`.
A typical code example is:
.. code:: c
#include <math.h>
// Set the camera gamma to be 0.7, so the gamma correction curve is y = 256 * (x / 256) ^ 0.7
static uint32_t s_gamma_curve(uint32_t x)
{
return pow((double)x / 256, 0.7) * 256;
}
isp_gamma_curve_points_t pts = {};
ESP_ERROR_CHECK(esp_isp_gamma_fill_curve_points(s_gamma_curve, &pts));

ESP_ERROR_CHECK(esp_isp_gamma_configure(isp_proc, COLOR_COMPONENT_G, &pts));
ESP_ERROR_CHECK(esp_isp_gamma_configure(isp_proc, COLOR_COMPONENT_B, &pts));
// Enable gamma module after curve parameters configured
