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 (10), an image processing portion (11), and a display (13). The sensor (10) detects a view direction and generates a view vector, and the image processing portion (11) comprises a view direction movement discriminator (14), a priority degree allocator (15), and a partial update portion (16). The view direction movement discriminator (14) calculates a view direction movement vector from the difference between the latest two fetched view vectors, the priority degree allocator (15) 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 centre of the display screen to a periphery along the projection vector, and the partial update portion (16) updates the display of the display screen in each divided section in accordance with the priority degree. <IMAGE> |
