Abstract

Structural information can be accurately drawn even for a secondary image generated by using resampled image data and mask data. There is provided an image processing device including a mask data acquisition unit that acquires mask data obtained by defining a degree of drawing for each pixel of image data, a resampling processing unit that generates resampled image data by performing resampling processing on the image data, a resampled mask data generation unit that calculates an estimated value obtained by estimating pixel values of the resampled image data based on the mask data and pixels included in a predetermined local region of the image data to generate resampled mask data in which a mask value for each pixel of the resampled image data is determined based on the pixel values of the resampled image data and the estimated value, and an image generation unit that generates an image of a drawing target from the resampled image data and the resampled mask data.

Dependent claims

An image processing device comprising:

a mask data acquisition unit that acquires mask data obtained by defining a mask value indicating a degree of drawing for each pixel of image data in order to extract a desired drawing target from the image data;
a resampling processing unit that generates resampled image data by performing resampling processing on the image data;
a resampled mask data generation unit that generates resampled mask data formed of mask values of respective pixels, obtained by defining a degree of drawing of the resampled image data, based on the mask data;
and
an image generation unit that generates an image of the drawing target by using the resampled image data and the resampled mask data,
wherein the resampled mask data generation unit includes
an estimated value calculation unit that calculates an estimated value obtained by estimating pixel values of the resampled image data based on the mask data and pixels included in a predetermined local region of the image data, and
a mask value determination unit that determines a mask value for each pixel of the resampled image data based on the pixel values of the resampled image data and the estimated value.
