Image processing device, image processing system, image processing method and image processing program

An image processing device comprising:

• conversion parameter calculation means for calculating a conversion parameter indicating a geometric transformation of a current frame with respect to a previous frame of input image data;
• an initial image generation means for transforming a high resolution image of the previous frame similar to a high resolution image of the current frame desired to be generated into an image that geometrically conforms to the high resolution image of the current frame by using the conversion parameter calculated by the conversion parameter calculation means;
• and
• high resolution image generation means for generating the high resolution image of the current frame by using the transformed image transformed by the initial image generation means as an initial value for generating a high resolution image.

A non-transitory computer readable medium storing an image processing program for causing a computer configuring an image processing device to execute the functions of:

• calculating a conversion parameter indicating a geometric transformation of a current frame with respect to a previous frame of input image data;
• transforming a high resolution image of the previous frame similar to a high resolution image of the current frame desired to be generated into an image that geometrically conforms to the high resolution image of the current frame by using the calculated conversion parameter;
• and
• generating the high resolution image of the current frame by using the transformed image as an initial value for generating a high resolution image.
