Disclosed are an image color enhancement method and a device. The method comprises: obtaining a first saturation of any pixel point in an image; processing the first saturation according to a first saturation conversion function to obtain a slope corresponding to the first saturation; obtaining a second saturation conversion function according to local detail information if the slope is smaller than a first preset threshold; processing the first saturation according to the second saturation conversion function to obtain a second saturation of the pixel point; calculating a target brightness value according to the second saturation; and adjusting an original brightness value to the target brightness value. Thereby, a different saturation enhancement method is adopted for the pixel points which are easy to cause the details in the image lost, so that the image vividness is enhanced, and the detail information is preserved to improve the sharpness.
