1. An image display method, performed by a computing device comprising a memory and a processor, the method comprising:
detecting a plurality of voxels overlapping in a depth direction in three-dimensional (3D) image data which is displayed on a general monitor or a 3D display device, wherein the 3D image data is a medical image of computed tomography (CT) or magnetic resonance imaging (MRI), wherein the 3D image data have voxels of a plurality of objects with different colors;
determining a first combination ratio for two colors based on transparency values of a first voxel and a second voxel of the plurality of voxels, wherein the first voxel belongs to a first object and the second voxel belongs to a second object;
generating a first mixed color by combining a color of the first voxel with a color of the second voxel at the first combination ratio; and
displaying the first mixed color at a position corresponding to the first voxel and the second voxel on the general monitor or the 3D display device,
wherein the determining of the first combination ratio comprises:
identifying a first weight value corresponding to the transparency value of the first voxel by using a first weight function that is proportional to the transparency value;
identifying a second weight value corresponding to a second transparency of a second voxel, by using a second weight function defined with an inflection point between a full transparency value and a full opacity value and increasing from the full transparency value to the inflection point and decreasing from the inflection point to the full opacity value; and
determining the first combination ratio based on a ratio of the first weight value to the second weight value.
