In order to make the above features and advantages of the present invention more comprehensible, the following embodiments are described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an image stabilization system according to an embodiment of the present disclosure.

Referring to FIG. 1 , the image stabilization system 10 includes an electronic device 11 and a detector 12 . The electronic device 11 includes a display 111, a connection interface 112, a memory 113, and a processor 114. The display 111 can be a liquid crystal display (LCD), a Light-Emitting Diode (LED) display, an Organic Light Emitting Display (OLED), or an electrophoretic display (Electro- Phoretic Display, EPD) or other types of displays.

The connection interface 112 is used to connect to the detector 12. The number of connection interfaces 112 can be one or more. The type of the connection interface 112 may be one or more. The connection interface 112 can include a wired and/or wireless connection interface to support wired and/or wireless communication standards.

In an embodiment, the connection interface 112 includes at least one wired connection interface and can support an Integrated Circuit Bus (I2C bus) standard, a Standard Mobile Imaging Architecture (SMIA) standard, and an action. Mobile Pixel Link (MPL) standard, Mobile Video Interface (MVI) standard, Mobile Display Digital Interface (MDDI) standard, Peripheral Component Interconnect Express (PCI) Express) One or more of the standard and Universal Serial Bus (USB) standards, and the supported physical connection standards are not limited to the above categories.

In an embodiment, the connection interface 112 includes at least one wireless connection interface and can support a Global System for Mobile Communication (GSM) system, a Personal Handy-phone System (PHS), and a code division. Code Division Multiple Access (CDMA) system, Wireless Fidelity (Wi-Fi) system, Worldwide Interoperability for Microwave Access (WiMAX) system, Long Term Evolution (Long Term Evolution, One or more of various wireless communication systems such as LTE) systems, Near Field Communication (NFC) systems, and Bluetooth systems, and the supported wireless communication systems are not limited to the above categories. In addition, a wireless connection interface can include various communication circuits such as an antenna and a high frequency circuit to perform related wireless communication functions.

The memory 113 can be any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory or the above components. The combination. In addition, the memory 113 may also include other types of storage media, which is not limited in this case.

The processor 114 is coupled to the display 111, the connection interface 112, and the memory 113. The processor 114 is, for example, a central processing unit (CPU) having a single core or a multi-core, or other programmable general purpose or special purpose microprocessor (Microprocessor), digital signal processor (Digital Signal) Processor, DSP), programmable controller, Application Specific Integrated Circuit (ASIC), embedded controller or other similar components or a combination of the above.

The detector 12 is configured to detect environmental information and correspondingly output a detection signal. The number of detectors 12 can be one or more. The type of the detector 12 can be one or more. In the present embodiment, the detector 12 is independent of the electronic device 11. However, in another embodiment, at least a portion of the detector 12 can also be a component of the electronic device 11.

In this embodiment, the processor 114 instructs the display 111 to display an image. This image can be a text, symbol, movie, or picture. For example, the content of the image is stored in the memory 113 and played by the display 111 after being processed by the image processing such as decoding by the processor 114. In addition, the processor 114 receives the detection signal from the detector 12 via the connection interface 112. At a particular point in time, the processor 114 performs an image stabilization procedure corresponding to the visual misalignment event based on the detection signal. For example, the processor 114 analyzes the environmental information detected by the detector 12 according to the detection signal and detects a visual misalignment event according to the analysis result of the environmental information. When a visual misalignment event that is about to occur or has occurred is detected, the processor 114 will then execute the corresponding image stabilization procedure.

In particular, the visual misalignment event referred to herein refers to a relative positional change between a viewer and the display 111. For example, assuming that the viewer is viewing the first display image displayed by the display 111 in front of the display 111, when the viewer moves with at least one of the display 111, the relative position between the viewer and the display 111 may be from the first position. Change to the second position. Wherein, if the relative position between the viewer and the display 111 is changed based on the viewer (eg, eye position), the display 111 may be up, down, left, right, or other directions relative to the viewer. mobile. That is, for the viewer, when a visual misalignment event occurs, the viewer may feel that (only) the display 111 is moved.

Generally, the visual misalignment event is caused by a sudden shaking or shaking of the viewer and/or display 111. For example, the visual misalignment event may be caused by a difference in the frequency of shaking (or vibration), shaking (or vibration), and/or shaking (or vibration) of the viewer and the display 111. Such shaking or vibration is often unpredictable or uncontrollable to the viewer. For example, if the viewer is on a moving vehicle (eg, a car, train, airplane, or MRT, etc.), the viewer and/or display 111 may sway as the vehicle travels. Alternatively, if the viewer uses the electronic device 10 while walking, the viewer and/or the display 111 may also shake as the viewing progresses.

When a visual misalignment event occurs, the viewer's eyes need to chase the shake or vibrate display 111 to continue to view the image displayed by the display 111 due to the relative positional change between the viewer and the display 111. Therefore, if a visual misalignment event occurs frequently, the viewer may need to spend considerable concentration to view the image displayed by the display 111. In some cases, the viewer may experience an uncomfortable situation such as dizziness or high eye pressure.

In this embodiment, when a visual misalignment event that is about to occur or has occurred is detected, the processor 114 adaptively adjusts the image displayed by the display 111 by the image stabilization program. For example, in the image stabilization program, the processor 114 adjusts the image displayed by the display 111 from the first display image to the second display image. The positioning position on the second display image is shifted by an offset distance in an offset direction relative to the original position of the positioning point on the first display image. That is to say, when the viewer itself and/or the display 111 suddenly shakes or vibrates, the image displayed by the display 111 moves the offset distance along the offset direction to prevent the viewer from displaying the image displayed by the display 111. The relative position between them occurs (too much). Therefore, even if a visual misalignment event occurs, the relative position between the viewer and the image displayed by the display 111 can be maintained (or not greatly varied). At the same time, the viewer's eyes do not need to chase the image displayed by the display 111 in the shaking or shaking, thereby alleviating the situation that the viewer feels uncomfortable.

2A-2C are schematic diagrams of an image stabilization program according to an embodiment of the present disclosure.

Referring to FIG. 2A, it is assumed that the display 111 is displaying the first display image and the dotted line R1 indicates that the relative position between the viewer 201 and the display 111 is in the first position. For example, one end of the broken line R1 is aligned with the eye of the viewer 201, and the other end of the broken line R1 is aligned with an anchor point LP on the first display image. At this time, the positioning point LP is located at an original position on the first display image.

Referring to FIG. 2B, assume that the processor 114 detects a visual misalignment event that causes the relative position between the viewer 201 and the display 111 to change to the second position indicated by the dashed line R2. For example, one end of the broken line R2 is still aligned with the eyes of the viewer 201, but the other end of the broken line R2 is moved over the display 111 by a distance D1 with respect to the broken line R1. That is, this visual misalignment event can be considered to be that the viewer 201 has moved a distance D1 upward relative to the display 111 (or the display 111 has moved a distance D1 downward relative to the viewer 201). Therefore, the processor 114 performs an image stabilization process to mitigate the effects of this visual misalignment event on the viewer. For example, when the viewer 201 moves upward by a distance D1 relative to the display 111, the processor 114 synchronously shifts the image displayed by the display 111 by a distance D2 (ie, an offset distance) to display the second display. image.

Referring to FIG. 2C, corresponding to the visual misalignment event, the display 111 displays the second display image. Wherein, relative to the original position of the positioning point LP in the first display image, the position of the positioning point LP in the second display image is also shifted upward by the distance D2, thereby aligning the eyes of the viewer 201. That is, with the image stabilization program, even if a visual misalignment event occurs, the eyes of the viewer 201 can be maintained at a position aligned with the anchor point LP.

In the present embodiment, the moving direction of the image displayed by the display 111 coincides with the changing direction of the relative position between the viewer 201 and the display 111. For example, in the embodiment of FIGS. 2A-2C, if a visual misalignment event occurs with reference to the viewer 201, the display 111 moves up and down relative to the viewer 201. Therefore, in the image stabilization program, the moving direction of the image displayed on the display 111 is also moved up and down with respect to the viewer 201. For example, if the vertical movement of the display 111 with respect to the viewer 201 is regarded as the movement of the display 111 in the y-axis direction, the image displayed by the display 111 is also moved along the y-axis direction of the display 111 in the image stabilization program. More specifically, when a visual misalignment event causes the display 111 to move downward (eg, the -y direction) relative to the viewer 201, the image displayed by the display 111 will be relative to the viewer 201 in the corresponding image stabilization program. Move up (for example, +y direction) as shown in Figure 2B. Alternatively, in another embodiment, when a visual misalignment event causes the display 111 to move upward (eg, the +y direction) relative to the viewer 201, the image displayed by the display 111 in the corresponding image stabilization program will Moves downward (eg, the -y direction) relative to the viewer 201.

In this embodiment, the processor 114 determines the moving distance D2 (ie, the offset distance) of the image displayed by the display 111 according to the detection signal. Wherein, the distance D2 is positively correlated with the magnitude of the change in the relative position between the viewer 201 and the display 111. In the present embodiment, the magnitude of change in the relative position between the viewer 201 and the display 111 is represented by the distance D1 and the distance D2 is equal to the distance D1. However, in another embodiment, the distance D2 may also approach the distance D1 and be greater or smaller than the distance D1.

In the present embodiment, when the relative position between the viewer 201 and the display 111 is in the first position, the display 111 displays the first display image. When the relative position between the viewer 201 and the display 111 is in the second position, the display 111 displays the second display image. Since a visual dislocation event corresponds to a sway or vibration at one time, the duration of a visual dislocation event is often quite short. When a visual misalignment event occurs, the relative position between the viewer 201 and the display 111 changes from the first position to the second position. Then, when the visual misalignment event ends, the relative position between the viewer 201 and the display 111 will return from the second position to the original first position.

In other words, after the display 111 displays the second display image in FIG. 2C, the processor 114 synchronously displays the display 111 corresponding to the relative position between the viewer 201 and the display 111 back to the first position indicated by the broken line R1. The displayed image is restored to the first display image in FIG. 2A. Thereby, during the occurrence of the entire visual misalignment event, even if the relative position between the viewer 201 and the display 111 continues to change, the relative position between the viewer 201 and the image displayed by the display 111 (or the anchor point in the image) It can still be maintained (or not very variable).

It is worth mentioning that although the embodiment of FIGS. 2A to 2C is an image displayed by moving the display 111 above/down to explain how to make the relative position between the viewer 201 and the image displayed by the display 111 in the image stabilization program. The first display image and the second display image can also be generated by capturing images in different regions of the original image.

Referring to FIG. 2A and FIG. 3A , before performing the image stabilization process (or detecting a visual misalignment event), the processor 114 captures the image located in the area 310 from the original image 301 as the first display image, and the display 111 This first display image will be displayed. For example, the size of the area 310 is approximately equal to the display screen (or screen) size of the display 111. After detecting the visual misalignment event as shown in FIG. 2B, the processor 114 performs an image stabilization procedure.

Referring to FIG. 2B and FIG. 3B, in the image stabilization program, the processor 114 determines the moving direction (ie, the offset direction) and the moving distance (ie, the offset distance) of the image (or the positioning point in the image) according to the detection signal. And the area 320 is located in the original image 301 accordingly. Wherein the size of the region 320 is equal to the size of the region 310, and the region 320 is shifted by an offset distance in the offset direction relative to the region 310 (eg, offset by a distance D2 in the -y direction).

Referring to FIG. 2C and FIG. 3C , after the positioning area 320 , the processor 114 captures an image located in the area 320 from the original image 301 as a second display image, and the display 111 displays the second display image. In addition, corresponding to the end of the visual misalignment event, after capturing the image located in the area 320, the processor 114 successively extracts the image located in the area 310 from the original image 301 as the first display image, and the display 111 will again This first display image is displayed.

In one embodiment, the original image 301 is a continuously played dynamic or still image, and the images captured from the area 310 and the area 320 are also consecutively played dynamic or still images.

It is worth mentioning that in each visual misalignment event, the change of the relative position between the viewer 201 and the display 111 can also be regarded as continuously changing multiple times, and the corresponding image stabilization program can also be included. Multiple adjustments to the image displayed by display 111.

In one embodiment, the image stabilization program is only executed after detecting an impending or occurring visual misalignment event. For example, in one embodiment, when the viewer moves in unison or synchronously with the display 111, the relative position between the viewer and the display does not change, so the image stabilization program is not executed.
