Abstract
This application relates to the field of image processing technologies, and discloses an image processing method and system, and a device, to resolve a problem that tone mapping greatly affects perception of a binocular 3D image. Based on a disparity map of a binocular image, a tone mapping curve is determined for a display device to display an image, instead of being generated merely based on image content. This makes a contrast of a tone mapped binocular image reach at least a level before tone mapping, thereby meeting a minimum disparity variation requirement for 3D perception by human eyes, and improving 3D perception of a 3D image displayed by the display device.
