    • An image interpolation device (310) includes a feature quantity calculating unit (313), an image interpolation processing unit (314), a resolution conversion processing unit (315) and a display control processing unit (316). With regards to pixels positioned in an interpolation subject area and peripheral pixels of the pixels, the feature quantity calculating unit (313) calculates feature quantities of the pixels. The image interpolation processing unit (314) extracts a pixel with the largest feature quantity from among the pixels positioned in the interpolation subject area. When the feature quantity of the extracted pixel is equal to a threshold or more, the image interpolation processing unit (314) sets a pixel value of the pixel as a pixel value of interpolation pixels. The resolution conversion processing unit (315) performs a resolution conversion on image data of which the interpolation pixels have been interpolated by the image interpolation processing unit (314). The display control processing unit (316) performs control to realign a plurality of pieces of image data including at least one piece of image data to which the resolution conversion has been performed by the resolution conversion processing unit (315) to a predetermined display configuration and display the realigned data.
    • 图像插值装置(310)包括特征量计算单元(313),图像内插处理单元(314),分辨率转换处理单元(315)和显示控制处理单元(316)。 关于位于内插对象区域中的像素和像素的周边像素,特征量计算单元(313)计算像素的特征量。 图像插值处理单元从位于插值对象区域的像素中提取具有最大特征量的像素。 当所提取的像素的特征量等于或等于阈值时,图像内插处理单元(314)将像素的像素值设置为内插像素的像素值。 分辨率转换处理单元(315)对由图像插值处理单元(314)插值的图像数据进行插值处理。 显示控制处理单元(316)执行控制以将包括由分辨率转换处理单元(315)执行的分辨率转换的至少一个图像数据的多个图像数据重新排列到预定显示配置, 显示重新排列的数据。
