Example Embodiment
[0013] like figure 1 shown, figure 1 It is a schematic flowchart of an image enhancement method according to an embodiment of the present invention. In this embodiment, the image enhancement method includes:
[0014] In step S11, at least two original RGB images collected for the same scene under different exposure times are acquired. Each raw RGB image has different brightness due to different exposure times.
[0015] In step S12, each original RGB image is converted into HSI space to obtain a luminance component image corresponding to each original RGB image, a saturation component image and a hue component image corresponding to at least one original RGB image, respectively. Generally speaking, the brightness of the original RGB images collected for the same scene at different exposure times is different, so after conversion to the HIS space, the same number of brightness component images as the original RGB images can be obtained. Since the acquisition is for the same ...
