The continuous image capturing of a subject is performed with small doses of radiation. A plurality of auxiliary images obtained by the continuous image capturing is stored. On the basis of the stored auxiliary images, the periodicity of motion of the subject is detected. A pseudo image is generated from the auxiliary images exhibiting the detected periodicity. The generated pseudo image is analyzed. On the basis of the analysis result, an image capturing parameter used for the main image capturing of a still image of the subject is calculated. Using the calculated image capturing parameter, the main image capturing of the still image of the subject is performed.

Radiographic image capturing apparatus and radiographic image capturing method

A three-dimensional image processing apparatus in which a three-dimensionally shaped model, a viewpoint (a camera) and a screen are set in a virtual the apparatus detects a two-dimensional position of a viewpoint of an operator and moves the screen according to the detected viewpoint position to map the three-dimensional shape of the model over the screen as viewed from the detected viewpoint position.

Image processing system

In a viewpoint detector instructions for a virtual 3-dimensional space are processed by an image processor. A virtual 3-dimensional spatial image is displayed in a field of view, and a viewpoint position of an operator in the field of view is detected. The 3-dimensional spatial image is displayed, and an image process for changing the image in accordance with the detected viewpoint position and an observation time is executed.

Image processing apparatus

An image processing apparatus converts color image data into hue, saturation and luminosity data. When a specific color portion and a range are designated in the hue data, processing for reducing tones is executed based on the designated data. Thereafter, a reverse-conversion into color image data is performed, thereby making it possible to output a high-quality image of an illustration. Further, a histogram of designated hue data is generated, processing for reducing tones is executed based on the histogram, and the data is subsequently reverse-converted into color image data. This makes it possible to output a higher quality image of an illustration.

Image processing suitable for changing the number of colors in an image

As image processing method suitable for creative image generation in which the image data of an original image are divided into plural areas each consisting of plural pixels, the shape of these areas is modified according to the image data of the original image, and the pixel data in each area are processed in accordance with a representative value of the image data.
