An image processing apparatus is provided including: a plurality of buffers, a first buffer from a among the plurality of buffers storing a first frame; and a controller configured to obtain frame information of a second frame, which includes second object information about a second object added in the second frame and second object location information indicating a second object area that is an area of the second object in the second frame, detect a duplicate area in the first frame, copy the duplicate area stored in the first buffer to a second buffer from among the plurality of buffers, and draw the second object in the second buffer based on the frame information.

Scanning display system in head-mounted display for virtual reality

Methods, systems, and computer programs are presented for the presentation of images in a head-mounted display (HMD). One HMD includes a screen, a processor, inertial sensors, a motion tracker module, and a display adjuster module. The motion tracker tracks motion of the HMD based on inertial data from the inertial sensors, and the display adjuster produces modified display data for an image frame to be scanned to the screen if the motion of the HMD is greater than a threshold amount of motion. The display data includes pixel values to be scanned to rows in sequential order, and the modified display data includes adjusted pixel values for pixels in a current pixel row of the image frame to compensate for the distance traveled by the HMD during a time elapsed between scanning a first pixel row of the image frame and scanning the current pixel row of the image frame.

Load adaptive power management for a display panel

This application relates to systems, methods, and apparatus for optimizing the operations of a power converter of a display panel based on image data to be output by the display panel. The power converter can include one or more switches that can be activated or deactivated based on the image data in order to shift a power efficiency of the power converter. Power efficiency is shifted as a result of balancing an amount of charge necessary for a load with an amount of resistance created when activating switches of the power converter. Therefore, by dynamically altering a configuration of a power converter based on image data, power efficiency of the power converter can be improved.

REDUCING MEMORY SIZE AND BANDWIDTH REQUIREMENTS FOR A NON-RECTANGULAR DISPLAY AND APPARATUS

An address to perform a memory operation on a memory location in a rectangular frame buffer is received. A determination is made whether the received address identifies a memory location in a non-rectangular frame buffer corresponding to a memory location in the rectangular frame buffer. Based on the determination that the received address identifies the memory location in the non-rectangular buffer, the memory operation on the memory location in the non-rectangular buffer is performed based on the translated address. Based on the determination that the received address does not identify the memory location in the non-rectangular buffer, the memory operation in the non-rectangular frame buffer is not performed.
