In a bid to improve in-body image stabilization (IBIS) for HDR, Canon has recently applied for a new patent to compensate for image movement between single photos. 

When shooting with Automatic Exposure Bracketing (AEB) with IBIS engaged, the single images created are prone to featuring slight differences due to camera movement between shots. However, it seems that this new patent will compensate for this movement, enabling photographers to achieve a sharper final image when capturing the exposures needed for a HDR.
