Abstract: An X-ray image diagnosis apparatus and a method for generating three dimensional image data of a moving body based on a plurality of two dimensional pixel data of the moving body that are automatically collected at different angle positions, wherein a plurality of radiography angle positions is previously designated, and the two dimensional pixel data is generated in correspondence with data of an object, e.g., a waveform of an electrocardiogram, collected at a real time. Based on the vital data, rotating movements for collecting a plurality of pixel data are decided. When a plurality of two dimensional pixel data obtained in correspondence with a plurality of heart beat cycles, for example, is collected at a certain designated angle position, the radiography position is automatically moved to a next collecting angle position. A set of a plurality of two dimensional pixel data collected at the same phase of the vital data of the moving body is selected for generating three dimensional image data.

Abstract: An image processing device extracts graphic areas, for example, firstly from image data received, and then extracts other remaining areas, i.e., photographic and character areas. The areas that are extracted firstly can be photographic or character areas. This prevents the areas to be extracted firstly from being extracted accompanying with other areas under the influence of isolation processes to be executed on other areas. The image processing device also can establish the order of extraction of each area depending on the contents of the image data based on the user's operation.
