Abstract
An image processing method includes obtaining a target picture and an initial tone mapping curve of the target picture, determining a plurality of interpolation points based on luminance information and/or dynamic metadata of the target picture, and determining a spline function that passes through the plurality of interpolation points, where the spline function is smoothly connected to the initial tone mapping curve at at least one of the plurality of interpolation points the initial tone mapping curve is modified based on the spline function to obtain a modified tone mapping curve of the target picture; and tone mapping is performed on the target picture based on the modified tone mapping curve. This image processing apparatus enables a display device to vividly and realistically reproduce a scene in a real world.
