Claim 10:
11. The high dynamic range image processing method according to claim 10, wherein verifying the accuracy of the maximum luminance modification value based on the maximum RGB component value of a third pixel corresponding to the third percentage in the HDR image, the maximum RGB component value of the fourth pixel corresponding to the third percentage inn the processed image, the maximum RGB component value of the fifth pixel corresponding to the fourth percentage in the HDR image, and the maximum RGB component value of the sixth pixel corresponding to the fourth percentage in the processed HDR image further comprises:
when PK3≠PK4 and PK3′−PK4′>T, determining that the maximum luminance modification value is accurate, wherein K3−K4<M, M is a preset first threshold, T is a preset second threshold, 0<T<2, K3 represents the third percentage, PK3 represents the maximum RGB component value of the third pixel, PK3′ represents the maximum RGB component value of the fourth pixel, K4 represents the fourth percentage, PK4 represents the maximum RGB component value of the fifth pixel, and PK4′ represents the maximum RGB component value of the sixth pixel.
