    摘要： In order to eliminate noise from an X-ray image by obtaining transform coefficients of a wavelet transform based upon information contained in tile-by-tile image data and obtaining image data based upon these transform coefficients, the entirety of a pre-processed original image is segmented into a plurality of tiles (S301). Wavelet transform coefficients of each tile obtained by segmentation are output (S302). Each tile is subjected to texture analysis and the results of analysis are output (S303). Next, a coefficient conversion is applied to the wavelet transform coefficients of each tile based upon the results of analysis (S304). High-frequency components among the transform coefficients are subjected to coefficient conversion. Next, an inverse discrete wavelet transform is applied to the wavelet transform coefficients of each area that has undergone conversion, whereby an image from which noise has been eliminated is output (S306).

    摘要： Processing for improving the contrast of an image of interest is executed by an image processing circuit in an X-ray photography apparatus. The image is decomposed into coefficient values of a plurality of frequency bands by a frequency-component decomposition circuit to obtain coefficients of each and every frequency band. A coefficient conversion circuit converts coefficient values with regard to at least one frequency band of the plurality of frequency bands in such a manner that a frequency distribution of coefficient values of every frequency band will become a prescribed frequency distribution. A restoration circuit generates an image using the coefficient values obtained by the conversion performed by the coefficient conversion circuit.

    摘要： There are provided an image processing apparatus and method. In this apparatus and method, high-frequency components are converted by multiple-frequency transformation in accordance with tone conversion used to change the dynamic range, thereby obtaining a high-quality image. For example, an original image undergoes tone conversion on the basis of a tone conversion curve, and the converted image then undergoes discrete wavelet transformation. After that, subbands obtained by discrete wavelet transformation undergo a conversion process in correspondence with the slope of the tone conversion curve.
