Abstract
In a diagnostic imaging device, such as an MRI device, correction processing improves an image to be a high-quality image and an imaging time is shortened. In the diagnostic imaging device, a noise reduction unitreduces a noise in observation data acquired with an observation unitand converted into an image, and the image correction unitcorrects the noise reduced data by correction processing that uses visual characteristics of human. The image correction unitseparates the noise reduced data into a broad luminance component and a local variation component, and generates a correction level map using the broad luminance component. Correcting the noise reduced data using this correction level map and the local variation component acquires a high-quality image that is competent in the clinical field.
