Abstract
An image processing unit generates a virtual environment or an artificial reality by displaying a necessary image in accordance with movement of a view direction of a person on a head mounted display and comprises a sensor, an image processing portion, and a display. The sensor detects a view direction and generates a view vector, and the image processing portion comprises a view direction movement discriminator, a priority degree allocator, and a partial update portion. The view direction movement discriminator calculates a view direction movement vector from the difference from the two fetched view vectors. The priority degree allocator generates a projection vector by projecting the view direction movement, determines a priority degree at each divided section of the display screen to be higher when the projection vector approaches and to withdraw from the center of the display screen to a periphery along the projection vector; and the partial update portion updates the display of the display screen in each divided section in accordance with the priority degree.
