the first image is obtained based on transformation of a second image, and
the second image is acquired based on the first position posture information.
6. The information processing apparatus according to claim 5 , wherein
the first image in the first display region is obtained based on transformation of a first part of the second image,
the transformation of the first part of the second image is based on the second position posture information,
the first image in the second display region is obtained based on transformation of a second part of the second image, and
the transformation of the second part of the second image is based on the third position posture information.
7. The information processing apparatus according to claim 6 , wherein the control unit is further configured to control, based on the second position posture information and the third position posture information, a first transformation amount of the second image which corresponds to the first display region and a second transformation amount of the second image which corresponds to the second display region.
8. The information processing apparatus according to claim 7 , wherein the control unit is further configured to render the first transformation amount same as the second transformation amount at the boundary between the first display region and the second display region.
9. The information processing apparatus according to claim 5 , wherein the control unit is further configured to generate the second image in a frame buffer based on the first position posture information.
10. The information processing apparatus according to claim 5 , wherein the control unit is further configured to generate the second image in a frame buffer that has a region larger than a whole display region of the display device which includes the first display region and the second display region.
11. The information processing apparatus according to claim 1 , wherein
when the display device is controlled to display the second display region after the first display region, the control unit is further configured to maintain the continuity based on render of a non-display of at least a part of the first image displayed in the first display region.
12. The information processing apparatus according to claim 1 , wherein the information processing apparatus is an optically transmissive head-mounted display.
13. An information processing method, comprising:
