Assume four around camera
Cam0 Cam1 Cam2 Cam3
AccL[0] AccR[0] AccL[1] AccR[1] AccL[2] AccR[2] AccL[3] AccR[3]
gain a[0] a[1] a[2] a[3]
To find a0,a1,a2,a3, so that adjusted color is continuous, i.e,
AccR[i]*a[i] =AccL[i+1]*a[i+1], i=0~3
Solution:
a[0] = 1
a[i] = AccR[i-1]/AccL[i], i=1~3
global_gain = Sum(AccR[i]+AccL[i])/4/Sum(AccR[0]+AccL[0])
a[i] = a[i]*overall_gain
Example:
