Image processing device, image processing method, and program

An image processing method of reproducing a state in which, using a first display device that displays an image, the image is displayed on a second display device having a characteristic different from that of the first display device, the method comprising:

• detecting motion of an image from an input image signal;
• developing the input image signal over a plurality of sub-fields;
• calculating, in a simulated manner, a light intensity integrated on retinas of a person at the time the person sees the input image signal displayed on the second display device, from a direction of the motion of the image and a light emitting pattern of the sub-fields;
• and
• generating an output image signal whose pixel value is the light intensity by
• determining a light-intensity integrating region in which the light intensity is integrated for a pixel of interest,
• regarding, as pixel sub-field regions, regions corresponding to the pixel of interest and having a length proportional to the light intensity of light emission in each of the sub-fields, and
• obtaining, for all pixel sub-field regions through which the light-intensity integrating region passes, influential light intensities corresponding to influences of the pixel sub-field regions on the pixel of interest based on ratios at which the light-intensity integrating region occupies the pixel sub-field regions.

A non-transitory computer readable medium having computer readable instructions thereon that when executed by a computer cause the computer to perform a method via an image processing device that reproduces a state in which, using a first display device that displays an image, the image is displayed on a second display device having a characteristic different from that of the first display device, the method comprising:
