## Background
BACKGROUND
Computing devices including mobile devices, portable devices, etc. that can display various textual and graphical information including, images, text, and video playback are becoming extremely popular. For example, many users may enjoy using the computing device to show home movies to their friends, play streaming videos from the interact or watch other videos downloaded directly to their computing device. However, these computing devices generally have a small screen size and a limited battery life.
In spite of those and other inherent limitations, users typically demand that such computing devices be capable of displaying content in high a quality form and without compromising battery life. Thus, shaky or jerky output caused by motion of the computing device or user is generally undesirable when a user is viewing information or a display scene.

DETAILED DESCRIPTION
Various embodiments are generally directed to making frame adjustments for an output of a display scene on a display device to compensate for motion of the computing device, a user of the computing device, a user's features, or combination thereof. Motion of the computing device, user, etc. may be caused by any number reasons. For example, a computing device may be mounted on a windshield of a car and may move due to the movement and bouncing of the car. In another example, a user may move the computing device by holding the device and moving his or her arm. In another example, the computing device may be fixed to an object such as a treadmill, however, the user may be moving on the treadmill. In some embodiments, both the computing device and the user may be moving. For example, a user may be walking down the street holding the computing device moving his or her arm.
In all these examples, the output may appear shaky, jerky and unwatchable due to the motion of the computing device, a user, a user's eyes, and so forth. Thus, various embodiments are directed to adjusting a frame of a display scene of the output to compensate for any of the motions described above. Moreover, the display scene may include any type of output, such as a video output stream, a text output, an image output, a graphical output, a webpage output, and so forth. Various embodiments are not limited in this manner and a display scene may output any type information that may be displayed on a display device.
Further, various techniques described herein are directed to adjusting a position, or a size of the frame of a display scene when presented on a display component of the computing device. The position and the size may be adjusted in any direction and may be based on the detected motion of the computing device, the user, the user's eyes, and so forth. For example, the computing device may include a camera component to detect and capture image information of the movement of the user and the user's eyes. The camera component may capture the image information and send the information to one or more other components of the computing device for further processing. In various embodiments, one or more image stabilization and feature tracking algorithms may be applied to the image information to determine the motion of the user (caused either by motion of the computing device or motion of the user), to determine the focus of the user's eyes and to track the movement of the user's eyes. As will be discussed in more detail below, this image motion information may be used to adjust the position or the size of one or more frames to compensate for the motion. However, processing the image information alone with the image stabilization and feature tracking algorithms may be processing intense and use too much battery power.
Thus, various embodiments may also include a motion sensor component to detect motion of the computing device. For example, the motion sensor component may be an inertial sensor, such as an accelerometer, which may detect motion of the device in any direction. This motion information may be directly used to adjust the position or size of the frame of a display scene. Furthermore, the motion information may be used as a motion estimation and a starting point for the one or more image stabilization and feature tracking algorithms when processing the image information. By using the motion estimation as a starting point, significant power and battery savings may be achieved due to less iterations of processing the image information. Various details will become more apparent by the following description.
With general reference to notations and nomenclature used herein, the detailed description that follows may be presented in terms of program procedures executed on a computer or network of computers. These procedural descriptions and representations are used by those skilled in the art to most effectively convey the substance of their work to others skilled in the art.
A procedure is here and is generally conceived to be a self-consistent sequence of operations leading to a desired result. These operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic or optical signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It proves convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to those quantities.
Further, the manipulations performed are often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein that form part of one or more embodiments. Rather, the operations are machine operations. Useful machines for performing operations of various embodiments include general-purpose digital computers or similar devices.
Various embodiments also relate to apparatus or systems for performing these operations. This apparatus may be specially constructed for the required purpose or it may comprise a general-purpose computer as selectively activated or reconfigured by a computer program stored in the computer. The procedures presented herein are not inherently related to a particular computer or other apparatus. Various general-purpose machines may be used with programs written in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the required method steps. The required structure for a variety of these machines will appear from the description given.
FIG. 1 illustrates a general overview of a computing system 100 including a computing device 105 for adaptively stabilizing output, such as a video output streamon a display device. More specifically, FIG. 1 illustrates computing device 105 including a camera component 102, a tracking component 104, a motion sensor component 106, a motion compensation component 108 and a display component 110. In various embodiments, the camera component 102 may receive or detect image information 120 and the motion sensor component 106 may receive or detect motion information 130. Although FIG. 1 shows a limited number of components, various embodiments may have any number of components for frame stabilization of a video stream output. Further, the various components may be implemented in software, hardware, or combination thereof.
In various embodiments, camera component 102 may include camera circuitry to capture, receive or detect image information, such as image information 120. The camera component 102 may be any type of camera including a still photo camera and/or a video camera capable of capturing the image information. In some embodiments, the camera component 102 may detect a user's face and facial features, such as a user's eyes, nose, mouth, ears, and so forth and the image information may include facial information. The camera component 102 may process the image information including the facial information and may send it to the other components of the computing device 105 for further processing. For example, the image information may be sent from the camera component 102 to the tracking component 104 for further processing.
The tracking component 104 may receive the image information 120 and apply any number of image stabilization algorithms and feature tracking algorithms to the image information to determine the motion of the computing device 102, a user, or both and to track one or features of the user. For example, the tracking component 104 may apply a parametric block matching algorithm, an optical flow estimation algorithm, linear region matching algorithm, a gray-coded bit plane matching algorithm, a point-to-line correspondence algorithm, a feature tracking algorithm, a pyramidal algorithm, a block matching algorithm or any other type of image stabilization or feature tracking algorithm to determine motion and feature track.
In some embodiments, the tracking component 104 may determine motion based only on image information 120 received by the camera component 102. However, in the same or other embodiments, the tracking component 104 may use motion information from the motion sensor component 106 to use as inputs to an image stabilization or feature tracking algorithm to reduce the amount of processing and energy used by the computing system 100 to calculate the motion. More specifically, the motion detected motion component 106 may be used as a motion estimate for an algorithm to start with when processing the image information to determine motion. By using this motion information as a starting point, an algorithm may reduce the number of iterations required to determine the motion of the computing device 105, a user, or both.
In addition to determining the motion of a computing device and/or the user, the tracking component 104 may receive the image information and may apply a feature tracking algorithm to track and determine motion of one or more features of a user, such as a user's eyes. In addition, feature tracking may be used to determine motion of the computing device and the user in any direction. More specifically, the tracking component 104 may detect a shift in a user's eyes indicating that the computing device, the user or both have moved. A shift in the user's eyes may be caused by the user trying to maintain focus on a particular point or object in a frame of a display scene on a display component of the computing device 105. In one example, a shift in the user's eyes in one direction may indicate that the computing device 105 has moved in the opposite direction relative to the user. In this example, either the user or the device may have actually moved and only the relative motion between the user and the device may be determined based on the feature tracking of the user's eyes. Further, a shift in the user's eyes may indicate that both the computing device 105 and the user have moved relative to each other. In this example, the computing device 105 and user may be moved in the same direction or in opposite directions and the detected shift in eyes may reflect both of these motions.
The tracking component 104 may also be capable of determining when the user's eyes are focused on an area of a frame of a display scene or not on the frame of the display scene at all. For example, the tracking component 104 may determine when a user is focused on a particular point in the frame, such as an object or person in the frame or on a particular piece of text in the frame. Moreover, the tracking component 104 may be able to detect when a user is looking at something other than the frame and is not focused on the information on the display component of the computing device 105. The tracking component 104 may communicate image motion information including tracking information to one or more components of computing system 100. The image motion information may be used to determine adjustments to one or more frames and whether a user is focused on a display scene.
In some embodiments, the computing device 105 may include a motion sensor component 106 to determine the motion of the computing device 105. The motion sensor component 106 may be any hardware, software and/or logic to detect motion of the computing device 105. The motion sensor component 106 may be one or more sensors to detect motion of the computing device 105 including an accelerometer, a gyroscope, a mercury switch, a micro-pendulum, an inertial sensor, or any other type of sensor to detect motion.
In various embodiments, the motion sensor component 106 may be used as a standalone component to determine the motion of the computing device 105 or may be used in conjunction with the camera component 102 to determine the motion of computing device 105 and/or a user. The motion sensor component 106 may detect the motion of the computing device 105 in any direction in space and may communicate the motion information to other components, such as the tracking component 104 to use as a motion estimate when processing image information and to the motion compensation component 108 to adjust a frame for presenting to a user on a display component 110.
The computing device 105 may also include a motion compensation component 108 to adjust one or more frames of an output, such as video output stream based on detected motion and feature tracking. More specifically, the motion compensation component 108 may adjust a position and/or size of one or more frames of a display scene within in a display component based on motion of the computing device 105, a user, or both. Further, the one or more frames may be adjusted based on information from only the camera component 102, only the motion sensor component 106, or a combination of both.
The motion compensation component 108 may receive image motion information from the tracking component 104 based on the image information 120 detected by the camera component 102 and the application of an image and feature tracking algorithm(s). The motion sensor compensation component 108 may also receive motion information 130 from the motion sensor component 106. In various embodiments, the image motion information and motion information may indicate the motion of the computing device 105, a user, or both in any direction in three dimensional (3D) space.
The motion compensation component 108 may adjust or stabilize a frame of an output presented to a user based on the image motion information, motion information, or combination thereof. For example, a user may be viewing a video output stream, such as a movie, a television show, streaming content, home video output, and so forth on a display component 110. Motion of the computing device 105 and/or the user may cause the video output stream to appear jerky and visually unappealing. However, one or more frames of the video output stream may be adjusted to compensate for the motion of the computing device, the user, or both. The one or more frames may be adjusted by a change in position within the display component or change in size within the display component, or both.
In various embodiments, the motion compensation component 108 may adjust a position of one or more frames by moving or shifting the frames in an upward direction, a downward direction, a left direction, a right direction, or combination thereof when presenting the frames on the display component. The direction of the adjustment may be based on the direction of the detected motion. More specifically, the motion compensation component 108 may adjust the frames in the opposite direction of the motion of a computing device 105. For example, if the computing system moves in an upward the one or more frames may be moved in a downward direction on the display component 110.
Further, the direction of the adjustment may also be based on a detected motion the user's eyes focused on the display component. In these embodiments, the direction of the adjustment may be in the same direction as the motion of the user's focus on the display component 110. For example, if the user's eyes move in an upward direction, the one or more frames may be adjusted in an upward direction.
In some embodiments, motion of the computing device 105, the user and/or the user's eyes may be detected simultaneously or nearly simultaneously. The motion compensation component 108 may adjust the position of one or more frames based on the relative motion of the computing device 105 and the motion of the user's eyes. For example, the tracking component may determine the user's eyes changing focus in a direction and the motion sensor component may detect the device moving in a direction. When the motion of the computing device 105 and the motion of the user's eyes are in the same direction, the combined relative motion between the computing device 105 and the user's eyes will be less than when only the device or the user's eyes move. For example, if the computing device 105 and the user's eyes both move in the upward direction, the relative motion between the computing device 105 and the user's eye will be less than if only the computing device 105 or the user's eyes moved in the upward direction. In another example, the computing device 105 and the user or user's eyes may move in opposite directions increasing the relative movement between themselves. In this example, the motion compensation component 108 may adjust or shift the frame more than if only the computing device 105 or the user's eye were in motion.
In various embodiments, the computing system, user and user's eye may move in any direction and the motion compensation component 108 may adjust or shift the one or more frames in any direction based on the relative movement of the computing system, user and the user's eyes. In some instances, the relative motion between the computing system and the user or user's eyes may be zero. In this case, the motion compensation component 108 may make no adjustment to the one or more frames of the video output stream.
The motion compensation component 108 may determine the magnitude of the adjustment of position or shift of the one or more frames based on the magnitude of the motion detected of the computing system, the user, the user's eye, or combination thereof. In various embodiments, the magnitude of the adjustment of position may be proportional to the magnitude of the motion detected. For example, in some embodiments, if the magnitude of the motion detected is 10 centimeters (cm), the magnitude of the adjustment of position may be 1/10th the magnitude of the motion detected or 1 cm. However, various embodiments are not limited in this manner and the magnitude of adjustment of position may be any factor or proportion of the magnitude of the motion detected.
In some embodiments, adjusting the position of the one or more frames of a display scene on the display component 110 may cause part of the frame to no longer be present on the display component 110. For example, if a frame is moved in an upward direction the top portion of the frame may no longer presented to the user as it is shifted out of the viewing area of the display component 110. Therefore, the motion compensation component 108 may adjust the size of one or more frames to compensate for the motion of the computing device 105, the user, the user's eyes or combination thereof. More specifically, the frame may be compressed in any direction including an upward direction from a bottom edge of the frame, a downward direction from a top edge of the frame, a left direction from a right edge of the frame, a right direction from a left edge of the frame, or combination thereof.
As similarly discussed above with respect to adjusting the position of the one or more frames, the size of the frames may be adjusted in a direction based on the motion of the computing device 105, the user, the user's eyes or combination thereof. In some embodiments, the frame may be compressed or the size of the frame may be adjusted in the same direction of the detected motion of the user's eyes. However, the frame may be compressed or the size of the frame may be adjusted in the opposite direction of the detected motion of the computing device 105. Moreover, the size of the frame may be adjusted based on the relative motion of the computing device 105 and the user's eyes as similarly discussed above with respect to the adjusting the position of the frames.
In various embodiments, the motion compensation component 108 may determine the magnitude of the adjustment of the size or compression of the frames based on the magnitude of the motion detected of the computing system, the user, the user's eye, or combination thereof. In various embodiments, the magnitude of the adjustment of size may be directly proportional to the magnitude of the motion detected. For example, in some embodiments, if the magnitude of the motion detected is 10 centimeters (cm), the magnitude of the adjustment of size may be 1/10th the magnitude of the motion detected or 1 cm. However, various embodiments are not limited in this manner and the magnitude of adjustment of size may be any factor or proportion of the magnitude of the motion detected.
The motion compensation component 108 may send the adjusted frames to a display component 110 and a display controller (not shown) for presenting the frame to the user on the display component 110. In some embodiments, the frames may be sent to the display component 110 at 120 hz or twice as fast as a display's normal refresh rate. By providing the frames at this faster rate, the video stream output stabilization may appear more smoothly to the user of the computing system 100. However various embodiments are not limited in this manner and the frames may be sent to the display component 110 and display controller at any rate.
In some embodiments, the tracking information may indicate that a user's eye are not focused on the display scene, but are focused something else. The motion compensation component 108 may send a black frame to the display component 110 and a display controller to present to the user. By sending the black frame, visual artifacts may be removed from the display component.
In various embodiments, the display component 110 may constitute any display device capable of displaying information received a processing component or a graphics processing unit. The display component 110 may include at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic Light Emitting Diode (OLED), a flexible display, a three-dimensional (3D) display, touchscreen and/or touch sensitive display and a projector, for example. The display component 110 may display a display scene of a video output or stream. In some embodiment, a computing device may include two or more display units. The display component 110 may display any information or data associated system 100.
FIG. 2 illustrates a first logic flow diagram 200 for frame stabilization during video output. At block 202, image information detected. More specifically, a camera component of a computing device may detect image information of a user, features of a user, other background features, or anything else within the viewing area of the camera component. Further, and at block 204, motion of a computing device may be determined In some embodiments, the image information alone may be used to determine motion of computing device when one or more stabilization and feature tracking algorithms are applied to the image information. However, a motion sensor component may also detect motion of the computing device based on a movement of the device or a user coupled with the device. Further, the motion information may be used as inputs during the image motion calculation when applying the one or more algorithms to detect motion based on the image information. More specifically, the motion information detected by the motion sensor may be used a motion estimate to start the calculations of the image motion information. By using the motion information detected by a motion sensor as a starting point when processing the image information processing power may be reduced and battery life may be saved.
In various embodiments, the logic flow 200 may include determining whether one or more features of a user, such as a user's eyes, are focused on a display scene displayed within display component at decision block 206. For example, the feature tracking component may apply the one or more algorithms to the image information to track user features. In various embodiments, the tracking component may determine whether a user is focused on the display component or if the user is focused on something other than the display component.
If at decision block 206, it is determined that the user and user's features are not focused on the display component, a black frame may be sent to a controller for display at block 208. For example, in some embodiments a feature tracking component may determine that a user's eyes are not focused on the display component and the feature tracking component may send image motion information to a motion compensation component including information indicating that a user's features are not focused on the display component. The motion compensation component may then send a black frame to a display controller based on the information.
If at decisions block 206, it is determined that user and user's features are focused on the display component, an adjustment to a frame may be made at block 210. More specifically, a motion compensation component may receive image motion information based on image information detected by a camera component and motion information detected by a motion sensor component. In some embodiments, the motion compensation component may only receive image motion information or motion information detected by a sensor from their respective components.
The motion compensation component may use the image motion information and the motion information to make one or more adjustments to a frame such as changing a position of the frame within the display component, changing the size of the frame within the display component or both. As previously discussed, when adjusting the position, the frame may be shifted in an upward direction, a downward direction, in a right direction, a left direction or combination thereof based on image motion information and/or motion information. Likewise, the size of the frame may be adjusted in an upward direction from a bottom edge of the frame, in a downward direction from a top edge of the frame, in a right direction from a left edge of the frame, a left direction from a right edge of the frame, or combination thereof
At block 212, the logic flow 200 may include sending the adjusted frame to a controller for processing and displaying on a display component. In some embodiments, the adjusted frame or the black frame from block 208 may be sent to the controller at a 120 Hz refresh rate such that the motion compensation for the output is appears smoother to a user.
The logic flow 200 may also include sending the adjusted frame or black from to the display component for presentation to a user at block 214. In various embodiments, logic flow 200 may be repeated any number of times including for each frame of the output. However, in some embodiments, logic flow 200 may only be invoked when motion is detected based on image information, motion information, or both. Although, logic flow 200 is depicted as occurring in a certain order various embodiments, are not limited in this manner and some blocks may occur before other blocks or may be processed in parallel.

Various embodiments are not limited to this example, the user's eyes may change focus in any direction and the device may move in any direction.
As previously discussed, one or more frames of video output may be adjusted based on the device motion 908 and the feature motion 1012. In embodiments, the computing device 902 may determine a relative motion between the device motion 908 and the feature motion 1012 to determine the amount of adjustment to apply to the one or more frames. For example, the computing device 902 may apply a larger adjustment when the device motion 908 and the feature motion 1012 are in opposite directions and a smaller adjustment when the device motion 908 and the feature motion 1012 are in the same direction. Further, the adjustment may be a shift or size adjustment made to the frame when displayed on the display component. Various embodiments are not limited in this manner.

Some embodiments may be described using the expression “one embodiment” or “an embodiment” along with their derivatives. These terms mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment. Further, some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. These terms are not necessarily intended as synonyms for each other. For example, some embodiments may be described using the terms “connected” and/or “coupled” to indicate that two or more elements are in direct physical or electrical contact with each other. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.
It is emphasized that the Abstract of the Disclosure is provided to allow a reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein,” respectively. Moreover, the terms “first,” “second,” “third,” and so forth, are used merely as labels, and are not intended to impose numerical requirements on their objects.
What has been described above includes examples of the disclosed architecture. It is, of course, not possible to describe every conceivable combination of components and/or methodologies, but one of ordinary skill in the art may recognize that many further combinations and permutations are possible. Accordingly, the novel architecture is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.
