## Title
Resolution loss mitigation for 3D displays

## Abstract

Systems, devices and methods are described including determining a display type and a display mode, preparing stereoscopic image content in response to the display mode, where preparing the stereoscopic image content includes storing a full resolution left image and a full resolution right image in memory, and determining a display refresh rate in response to at least a content frame rate of the stereoscopic image content. The stereoscopic image content may then be processed for display according to the display type, the display refresh rate, and a power policy.

## Background
BACKGROUND
Polarization based stereoscopic displays and auto-stereoscopic displays all suffer from resolution loss. Polarization based stereoscopic displays operate by modulating each row of the display in opposite polarization directions. When viewed using glasses incorporating passive polarizers only half of the screen content goes to each eye resulting in 50% resolution loss.
Auto stereoscopic displays work by spatially separating the light rays emanating from the display. For single-view auto stereoscopic displays, resolution loss is 50%. For multi-view auto stereoscopic display, the resolution loss increases as a function of the number of views provided. One type of auto stereoscopic display is parallax barrier based. Parallax barrier based displays employ an active switching barrier layer to alternately direct light to the right and left eyes on a per-frame basis.

FIG. 1 illustrates an example system 100 in accordance with the present disclosure. In various implementations, system 100 includes a graphics module 102 including a media module 104, a memory 106 and a display module 108. Graphics module 102 is operatively and communicatively coupled to a stereoscopic three-dimensional (S3D) display 110 such as a polarization based stereoscopic display or an auto stereoscopic display such as a parallax barrier based display. In various implementations, as will be explained in greater detail below, configuration data 112 may be exchanged between module 102 and display 110. Further, as will also be explained in greater detail below, display module 108 may retrieve image content from memory 106, may format that image content for display, and may provide the image content to display 110 in the form of frame data 114. When doing so, display module 108 may provide a synchronization signal 116 to display 110 to aid in the rendering of frame data 114 as will be explained in greater detail below.
As will be explained in greater detail below, when graphics module 102 determines the type of display 110, and determines, based on a display mode of display 110, that display 110 is prepared to receive stereoscopic image content 118, module 102 may use media module 104 to prepare stereoscopic image content 118 for display. Media module 104 may do so by storing full resolution left and right images of content 118 in memory 106. Then, depending on at least a frame rate of stereoscopic image content 118, module 102 may determine a refresh rate to be used when displaying stereoscopic image content 118 on display 110. Further, in response to the type of display 110, display module 108 may process stereoscopic image content 118.
Media module 104 and display module 108 may be implemented by any combination of software, firmware and/or hardware. Thus, in various implementations, hardware logic such as a hardware engine may provide the functionality of media module 104 and/or display module 108 as described herein, while, in other implementations, modules 104 and/or 108 may be implemented by software such as driver software.
In various implementations, memory 106 may be any type of memory device or devices including volatile memory such as any type of Static Random Access Memory (SRAM), any type of Dynamic Random Access Memory (DRAM), and so forth. In various implementations, display 110 may be any type of S3D display such as, but not limited to, a polarization based display, a parallax barrier based display, and so forth.
In various embodiments, a video and/or media processor may implement graphics module 102. In general, various components of system 100 may be implemented in software, firmware, and/or hardware and/or any combination thereof. For example, various components of system 100 may be provided, at least in part, by hardware of a computing system-on-a-chip (SoC) such as may be found in a computing system, consumer electronics (CE) device or the like. In various implementations, module 102 may be provided by software and/or firmware instructions executed by processing logic such as one or more central processing unit (CPU) processor cores, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a Fully Programmable Gate Array (FPGA), and so forth.
FIG. 2 illustrates a flow diagram of an example process 200 according to various implementations of the present disclosure. Process 200 may include one or more operations, functions or actions as illustrated by one or more of blocks 202, 204, 206, 210 and 212 of FIG. 2. By way of non-limiting example, process 200 will be described herein with reference to example system 100 of FIG. 1.
Process 200 may begin at block 202 where a display type and a display mode may be determined. In various implementations, block 202 may correspond to display 110 providing configuration data 112 to module 102 where data 112 may include at least display type data and display mode data for display 110. In various embodiments, display type data may indicate that display 110 is one of a polarization based S3D display or a parallax barrier based S3D display, although the present disclosure is not limited to any particular S3D display type and/or technology. In various embodiments, display mode data may indicate whether or not display 110 has 3D display capability and/or is in a 3D display mode. In some embodiments, block 202 may involve module 102 obtaining configuration data 112 from display 110 by, for example, accessing registers (not shown) internal to display 110. In other embodiments, block 202 may involve module 102 receiving configuration data 112 from display 110 when, for example, module 102 requests that display 110 provide configuration data 112.
At block 204, stereoscopic image content may be prepared in response to the display mode, wherein preparing the stereoscopic image content includes storing a full resolution left view image and a full resolution right view image in memory. In various implementations, if the display mode indicates that display 110 is in a 3D display mode and hence is ready to receive content 118, block 204 may involve media module 104 writing content 118 in the form of a full resolution left view image and a full resolution right view image in memory 106. For example, FIG. 3 illustrates a scheme 300 in accordance with the present disclosure that includes some features of system 100 depicted in the context of process 200. As depicted in scheme 300, block 204 may involve media module 104 storing a left view image 302 and a tight view image 304 in memory 106. For example, stereoscopic image content 118 may include an alternating sequence of full resolution left view and right view images organized as rows and columns of pixel values as depicted by example images 302 and 304.
Process 200 may then continue at block 206 where a display refresh rate may be determined in response to at least a content frame rate of the stereoscopic image content. In various implementations, graphics module 102 may determine a display refresh rate at block 206 in response to the frame rate of stereoscopic image content 118 and a power policy. Further, module 102 may determine a display refresh rate at block 206 in response to whether content 118 is progressive scanned content or interlaced content.
In various implementations, if the frame rate of content 118 is N hertz, then graphics module 102 may determine, a display refresh rate of either N hertz or 2*N hertz depending on a power policy and/or whether content 118 is progressive scanned or interlaced content. In various embodiments, a power policy associated with system 100 may specify that module 102 should employ a lower display refresh rate and/or provide display content 118 in interlaced format to implement a power saving mode. Alternatively, if a power saving mode is not to be implemented, the power policy may specify that module 102 should employ a higher display refresh rate to implement an enhanced visual quality mode. For example, if content 118 has a frame rate of sixty (60) hertz and is progressive scanned, then, in an enhanced visual quality mode, module 102 may undertake block 206 by setting the display refresh rate to one-hundred twenty (120) hertz, whereas in power saving mode, module 102 may undertake block 206 by setting the display refresh rate to sixty (60) hertz. In another example, if content 118 has a frame rate of thirty (30) hertz and is progressive scanned, the module 102 may undertake block 206 by setting the display refresh rate to sixty (60) hertz while providing full resolution (e.g., as shown in FIG. 3). In addition, as will be explained further below, module 102 may, for content 118, use display module 108 to process content 118 for display by providing content 118 in interlaced format to display 110.
Process 200 may continue at block 208 where the stereoscopic image content may be processed for display in response to the display type and the display refresh rate. In various implementations, referring again to FIG. 3, in response to both the display type determined at block 202 and the display refresh rate determined at block 206, display module 108 may undertake block 208 by forming either horizontally interlaced frames 306 from alternate rows of images 302 and 304, or vertically interlaced frames 308 from alternate columns of images 302 and 304. For instance, when the display type specifies that display 110 is a polarization based S3D display, block 208 may involve display module 108 assembling frames 306 by accessing memory 106 to alternately obtain rows of pixel values of images 302 and 304. Alternatively, when the display type specifies that display 110 is, for example, a parallax barrier based S3D display, block 208 may involve display module 108 assembling frames 308 by accessing memory 106 to alternately obtain columns of pixel values of images 302 and 304.
At block 210, the processed stereoscopic image content may be provided to a stereoscopic display. In various implementations, display module 108 may provide the processed image content to display 110 at block 210. For example, if display 110 is a polarization based S3D display, module 108 may provide frames 306 in the form of frame data 114 to display 110. Alternatively, for example, if display 110 is a parallax barrier based S3D display, module 108 may provide frames 308 in the form of frame data 114 to display 110. When doing so, module 108 may provide frames 306 or 308 to display 110 at the display refresh rate as determined in block 206.
Process 200 may conclude at block 212 where a synchronization signal may be provided to control display of the processed stereoscopic image content by synchronizing a stereoscopic control mechanism of the stereoscopic display with the processed stereoscopic image content. In various implementations, display module 108 may undertake block 212 by providing synchronization signal 116 to display 110. For example, synchronization signal 114 may have the same frequency as the display refresh rate determined in block 206 and may be used to control a stereoscopic control mechanism of display 110 in synchronization with the image content provided at block 210. For example, the stereoscopic control mechanism of display 110 may be controlled using synchronization signal 116 so that display 110 provides two image views (e.g., corresponding to the left view image 302 and right view image 304 of FIG. 3) by either spatially separating the views (e.g., by using parallax harriers) or by using polarization to separate the views.
For instance, if display 110 is a polarization based S3D display, block 212 may involve using synchronization signal 116 to control an active retarder/polarization layer of display 110 to modulate each row of display 110 in opposite polarization directions in successive frames 306 (e.g., in one polarization direction for frame N, and in the other polarization direction for frame N−1). Alternatively, for example, if display 110 is a parallax barrier based S3D display, block 212 may involve using synchronization signal 116 to control parallax barriers internal to display 110 in order to modulate each column of display 110 in response to frames 308.
While implementation of example process 200, as illustrated in FIG. 2, may include the undertaking of all blocks shown in the order illustrated, the present disclosure is not limited in this regard and, in various examples, implementation of process 200 may include the undertaking only a subset of the blocks shown and/or in a different order than illustrated.
