Claim Text:
1. An image display device, comprising: a first processor; first computer-readable storage media connected to the processor and which store: a plurality of rendering elements each of which comprises a combination of rendering target information, which specifies a rendering target, and rendering settings information, which is referred to when the rendering target is rendered, and a respective place in a priority order assigned to each of the plurality of rendering elements, where the rendering target information comprises data identification information for specifying three-dimensional signal value arrangements which are rendering targets, and mask information for specifying a rendering target area out of the three-dimensional signal value arrangements, and where the rendering settings information comprises information for specifying a rendering method of rendering a two-dimensional image based on the three-dimensional signal value arrangements, and information for specifying a rendering parameter to be applied to the rendering method; and a display part connected to the first processor, wherein the first computer-readable storage media further store instructions that, when executed on the first processor, cause the first processor to: display the rendered two-dimensional image on the display part, wherein the priority processing comprises one of first priority processing, second priority processing, or third priority processing, where: the first priority processing comprises removing, from the target area that is lower in the priority order out of two target areas that are at least partially on the same projection ray, a portion that is on the same projection ray, the second priority processing comprises removing, from the target area that is lower in the priority order out of two target areas that at least partially overlap with each other, the overlapping portion, and the third priority processing comprises creating a new rendering parameter by integrating two rendering parameters that are comprised in two rendering elements associated with two target areas that at least partially overlap with each other, and at least partially switching the two rendering parameters that are comprised in the two rendering elements to the new rendering parameter, and wherein the first computer-readable storage media further store instructions that, when executed on the first processor, cause the first processor to:
