The present invention provides an image display method and a device. The method includes: obtaining, according to a first RGB parameter of a pixel of an image and a first gamma value corresponding to the first RGB parameter, a second RGB parameter corresponding to a second gamma value, where a second transmittance of the second RGB parameter is equal to a first transmittance of the first RGB parameter; obtaining an H parameter and a V parameter according to the first RGB parameter, and obtaining an S parameter according to the second RGB parameter; obtaining a third RGB parameter according to the H parameter, the S parameter, and the V parameter; and displaying the pixel according to the third RGB parameter. According to the present invention, a first RGB parameter is transformed into a second RGB parameter by using a gamma curve (that is, a first gamma value) corresponding to the first RGB parameter and another gamma curve (that is, a second gamma value). As the RGB parameter is transformed by using an exponential relationship, smooth transition in color adjustment can be ensured, and no color spot appears, thereby avoiding an image distortion. |
