2 is a flow chart of a method for adaptively adjusting a three-dimensional display setting according to a first embodiment of the present invention. Hereinafter, the detailed steps of the method for adaptively adjusting the three-dimensional display setting of the present embodiment will be described with reference to each module in FIG. 1 : Please refer to FIG. 1 and FIG. 2 at the same time. First, in step S210, the analysis The module 110 receives a three-dimensional image, and the three-dimensional image includes one or more objects. Each object is synthesized from a left eye image and a right eye image to produce a three-dimensional image having a depth of field effect. Therefore, the analysis module 110 is used to analyze the aberration setting values of the left eye and right eye images in each object.

Then, in step S220, the detecting module 120 detects the viewing parameters of the user viewing the three-dimensional stereoscopic display 10. In this embodiment, the viewing parameters include the screen size of the three-dimensional stereoscopic display 10, the resolution of the three-dimensional stereoscopic display 10, the viewing distance between the user 20 and the three-dimensional stereoscopic display 10, and the inter-pull distance of the user 20 (Interpupillar Distance, IPD). )and many more. The screen size can be divided into, for example, 3 to 300 inches; the resolution can be divided into Full HD image quality, HD image quality or DVD image quality, etc.; the viewing distance range is approximately 0 to 10 meters; It varies from person to person, but it is mainly related to race, gender, and age. For example, the Nordic people have a large gap, and the Japanese have a small gap. The screen size, resolution, viewing distance, and pupil distance described above all affect the viewing effect of the user 20 viewing the three-dimensional image, so it is used as an ornamental parameter.

The detection module 120 can obtain the viewing parameters by, for example, detecting a preset value set internally by the three-dimensional display 10 . The detection module 120 can also be used with an image capturing device (not shown) to capture the image of the user 20, and use the image to detect the user's 20 distance. The detection module 120 can also detect the distance between the three-dimensional display 10 and its remote controller as the viewing distance, or directly detect the distance between the user 20 and the three-dimensional display 10 by using the related distance detection algorithm. As an ornamental distance.

On the other hand, in addition to detecting the viewing parameters through the detection module 120, the settings of the user 20 can be received. For example, the user can display the screen size through the menu displayed on the screen of the three-dimensional display 10, respectively. Set the resolution, viewing distance, and distance.

After obtaining the viewing parameters, proceeding to step S230, the determining module 130 calculates a visual range suitable for the three-dimensional viewing according to the viewing parameters. In detail, the judging module 130 uses the viewing parameter as a query condition to query the visual range of the corresponding table that meets the query condition. The corresponding table records a plurality of different combinations of viewing parameter examples, and each example can be queried. The visual range for 3D viewing. As shown in Table 1 below, Table 1 is a correspondence table of viewing parameters and visual ranges according to the first embodiment of the present invention.

Referring to Table 1, when the detection module 120 detects a screen size of 24 inches, a resolution of Full HD (FHD) quality, a viewing distance of about 0.6 meters, and a pupil distance of 6.25 cm, the above viewing is performed. As a query condition, the parameter can find the visual range that meets the query condition in the query correspondence table. As shown in Table 1, the first example is a visual range that satisfies the above viewing parameters, that is, a three-dimensional image with an aberration between 28 and 42 pixels is a visual range suitable for three-dimensional viewing. When the detection module 120 detects that the screen size is 60 inches, resolution is Full HD (FHD) quality, viewing distance is about 3 meters and the distance is 6.25 cm (the second case), when the aberration falls between 30 and 85 pixels. The image is a visual range suitable for three-dimensional viewing. The correspondence table between the viewing parameters and the visual range of the present invention is not limited to the above, and the content thereof can be expanded according to the actual application.

In step S250, if the determining module 130 determines that the aberration of at least one object in the three-dimensional stereo image does not meet the visual range, the adjustment module 140 can directly adjust the aberration of the object. However, if the adjustment module 140 directly adjusts an object that does not conform to the visual range, the adjusted three-dimensional image may not appear natural. Therefore, the adjustment module 140 can also calculate a numerical distribution for the aberrations of the objects, and compare the numerical distribution and the visual range, and perform each object in the three-dimensional stereo image according to a formula or a mapping table. Re-mapping, where a formula or mapping table is established based on viewing parameters. Accordingly, the numerical distribution of the aberrations of each object after adjustment is in accordance with the visual range, and the adjusted three-dimensional stereoscopic image is displayed on the three-dimensional display 10.

First, in step S410, the analysis module 110 receives a three-dimensional stereoscopic image, and the three-dimensional stereoscopic image includes one or more objects. The analysis module 110 is configured to analyze the aberration setting values of the left eye and right eye images in each object.

Next, in step S420, the detecting module 120 detects the viewing parameters of the user viewing the three-dimensional stereoscopic display 10. In this embodiment, the viewing parameters include the device information of the source device and the image of the three-dimensional image, which provide the three-dimensional image, in addition to the screen size, the resolution, the viewing distance, and the pupil distance described in the first embodiment. News. The source device is, for example, a Blu-ray player for playing 3D movies, a game console for playing 3D video games, a home camera for playing 3D movies, and a digital device for playing 3D photos. Camera and more. The image information is, for example, the aperture, shutter, focal length, etc. of the three-dimensional image. Wait.

The detection module 120 can detect a source device that provides a three-dimensional image through a high-resolution multimedia interface (HDMI) consumer electronics control (CEC) signal line. The detection module 120 can also obtain information about the camera model, shooting time, aperture, shutter, focal length, and the like of the three-dimensional image by using an Exchangeable Image File Format (EXIF) for detecting a three-dimensional image. By understanding the source device or image information that provides the three-dimensional image, it is advantageous to calculate the visual range suitable for three-dimensional viewing, so it is used as an ornamental parameter.

Similarly, in addition to detecting the viewing parameters through the detection module 120, the user's settings can be received, for example, a menu displayed by the user through the screen of the three-dimensional display 10, respectively, to the source device or source. The purpose of the end device is set.

After obtaining the viewing parameters, proceeding to step S430, the determining module 130 calculates a visual range suitable for the three-dimensional viewing according to the viewing parameters. The judging module 130 uses the viewing parameter as a query condition to query the visual range of the corresponding table that meets the query condition. The corresponding table records a plurality of different combinations of viewing parameter examples, and each example can query the three-dimensional viewing. Vision range. As shown in Table 2 below, Table 2 is a correspondence table between the viewing parameters and the visual range according to the second embodiment of the present invention.

Referring to Table 2, when the detection module 120 detects that the source device is a Blu-ray disc player for playing a movie, and the shooting condition is preset to be played in a movie theater, for example, using a 730-inch large screen, Full The HD (FHD) image quality and viewing distance are about 20 meters. Using the above viewing parameters as the query conditions, the visual range that meets the query conditions can be found in the query correspondence table. As shown in Table 2, the second example is a visual range that satisfies the above viewing parameters, that is, a three-dimensional image with an aberration between 1 and 6 pixels is a visual range suitable for three-dimensional viewing. When the detecting module 120 detects that the source device is a digital camera, the purpose is to play a 3D photo, and the detecting module 120 uses the EXIF to obtain image information about the focal length/shutter/resolution/aperture. It can be seen from the query in Table 2 that the first example is in accordance with the above-mentioned viewing parameter condition, that is, the three-dimensional image with the aberration between 69 and 101 pixels is the visual range suitable for three-dimensional viewing.

Next, in step S440, the determining module 130 determines whether the aberration of each object meets the visual range according to the analysis result of each object by the analysis module 110. If there is at least one object in the three-dimensional image If the difference does not meet the above-mentioned visual range, then the step S450 is continued, and the prompting module 350 marks the object that does not meet the visual range in the displayed three-dimensional stereoscopic image. For example, the prompting module 350 may not conform to the visual range. The object is marked with a frame or marked with a different color. The form of the mark is not limited herein, and the mark that allows the user to recognize that the object does not conform to the visual range is the spirit of the present invention.

Next, in step S460, the prompting module 350 can also display a prompt screen on the screen of the three-dimensional stereoscopic display, thereby prompting the user whether it is necessary to adjust the aberration of each object. If not, the method flow is ended (step S470); if yes, then in step S480, the adjustment module 140 adjusts the aberration of each object to conform to the visual range, and outputs the adjusted three-dimensional stereoscopic image to the three-dimensional display 10, To display this adjusted 3D stereoscopic image. Step S480 is similar to step S250, and details thereof will not be described herein.

Third embodiment

FIG. 5 is a flow chart of a method for adaptively adjusting a three-dimensional display setting according to a third embodiment of the present invention. The method for adaptively adjusting the three-dimensional display setting of the present embodiment is applicable to the apparatus 300 for adaptively adjusting the three-dimensional display setting of the second embodiment. The detailed steps of the embodiment will be described below with reference to the modules in FIG.

Referring to FIG. 5 and FIG. 3 simultaneously, in step S510, the analysis module 110 receives a three-dimensional stereoscopic image, and the three-dimensional stereoscopic image includes one or more objects. The analysis module 110 is configured to analyze the aberration setting values of the left eye and right eye images in each object.

Next, in step S520, the detecting module 120 detects the viewing parameters of the user viewing the three-dimensional stereoscopic display 10. In this embodiment, the viewing parameters include the screen size, the resolution, the viewing distance, the lay length, and the device information of the source device for providing the three-dimensional stereo image described in the second embodiment.

The detection module 120 can detect the three-dimensional viewing mode preset in the three-dimensional display 10 as an ornamental parameter. The three-dimensional viewing mode may be a keep comfort mode, a keep space mode, or a custom mode. Specifically, the comfort priority mode maintains the comfort level of the three-dimensional image preset playback screen and the current viewing screen. In order to maintain the user's viewing comfort, it is usually necessary to increase or decrease the 3D effect. The space priority mode is to maintain the space of the preset playback of the 3D stereoscopic image and the current viewing of the screen. In order to maintain the space experience of the user, it is usually necessary to increase or decrease the 3D effect. The custom mode is based on the aberrations obtained by screen size, resolution, viewing distance, and pupil distance, where the minimum value of the aberration is the most recent value, and the maximum value of the aberration is the farthest value. The custom mode is further provided. Set the nearest value and the farthest value by yourself. In addition to the above-described three-dimensional viewing mode, those skilled in the art can increase or decrease the three-dimensional viewing mode of the three-dimensional stereoscopic display 10 according to actual use.

Since the three-dimensional viewing mode takes the user's perception as a priority, in step S530, the prompting module 350 displays a prompt screen in the three-dimensional stereoscopic image, thereby prompting the user to select the comfort priority mode and space. One of the priority mode or the custom mode is used as an ornamental parameter. As shown in FIG. 6, FIG. 6 is an embodiment of a prompt screen for selecting a three-dimensional viewing mode according to a third embodiment of the present invention. If the user selects the custom mode, the user can further display a menu displayed on the screen of the three-dimensional display 10, as shown in FIG. 7. FIG. 7 is a three-dimensional display 10 according to the third embodiment of the present invention. One of the menus shown on the screen. The user can further set other viewing parameters through the menu 710, such as screen size, resolution, viewing distance, pitch, device information of the source device providing the three-dimensional image, and image information of the three-dimensional image, the latest value of the aberration With the farthest value and so on.

After obtaining the viewing parameters, proceeding to step S540, the determining module 130 calculates a visual range suitable for the three-dimensional viewing according to the viewing parameters. The judging module 130 uses the viewing parameter as a query condition to query the visual range of the corresponding table that meets the query condition. The corresponding table records a plurality of different combinations of viewing parameter examples, and each example can query the three-dimensional viewing. Vision range. As shown in Table 3 below, Table 3 is a correspondence table between the viewing parameters and the visual range according to the third embodiment of the present invention.

Comparing the first example of Table 3 with the first example of Table 1, it can be seen that when the pitch of the first example of Table 1 is changed from 6.25 cm to 5 cm, and the three-dimensional viewing mode is set to the comfort priority mode, The visual range suitable for three-dimensional viewing also changes, and the visual range suitable for three-dimensional viewing is changed from 28 to 42 pixels to an aberration of 23 to 34 pixels. Comparing the third example of Table 3 with the second example of Table 1, it can be seen that when the screen size of the second example of Table 1 is changed from 60 inches to 100 inches, and the three-dimensional viewing mode is set to space priority. In the mode, the visual range suitable for three-dimensional viewing also changes. The visual range suitable for three-dimensional viewing is changed from 30 to 85 pixels to aberration and should fall between 18 and 51 pixels.

Table 4 is a correspondence table of another viewing parameter and a visual range according to the third embodiment of the present invention. The difference between Table 4 and Table 2 is only the condition for increasing the three-dimensional viewing mode as the viewing parameter, and there are different visual ranges suitable for three-dimensional viewing depending on the set three-dimensional viewing mode.

Next, in step S550, the determination module 130 determines whether the aberration of each object meets the visual range according to the analysis result of each object by the analysis module 110. If the aberration of at least one of the three-dimensional images does not meet the visual range, then the step S560 is followed, and the prompting module 350 displays the non-compliant prompt message in the displayed three-dimensional stereo image, or the visual range is not met. The object is marked with a mark.

Next, in step S570, the prompting module 350 can also display a prompt screen on the screen of the three-dimensional stereoscopic display, thereby prompting the user whether it is necessary to adjust the aberration of each object. If not, the method flow is ended (step S580); if yes, then in step S590, the adjustment module 140 adjusts the aberration of each object to conform to the visual range, and outputs the adjusted three-dimensional stereoscopic image to the three-dimensional stereoscopic display 10, To display this adjusted 3D stereoscopic image.

In order to make the content of the embodiment more clear, the following is further assisted by FIG.

Therefore, in step S560, the excess portion is marked (dotted line 804). Next, in step S570, a prompt screen 805 is displayed on the screen of the three-dimensional stereo display to indicate whether the user needs to adjust the aberration of each object. If not, the method flow is ended (step S580); if yes, then in step S590, the adjustment module 140 adjusts the aberration of each object to conform to the visual range, and outputs the adjusted three-dimensional stereoscopic image to the three-dimensional stereoscopic display 10, To display this adjusted 3D stereoscopic image. At this time, the objects 801 to 803 have been adjusted to the solid line F, that is, the objects 801 to 803 are all within the farthest value of the visual range suitable for the three-dimensional viewing.

Referring to FIG. 8(b), the three-dimensional image includes three objects 804-806, and the objects 804-806 are located within the range of the solid line N and the solid line F, that is, the objects 804-806 are suitable for three-dimensional viewing. The range of the difference between the nearest value and the farthest value of the visual range is not required to be adjusted.

Referring to FIG. 8(c), the three-dimensional image includes three objects 807-809, wherein the object 807 is located at a position about the solid line N, that is, the object 807 is located at the nearest value of the visual range, so the three-dimensional A prompt screen 811 is displayed on the screen of the display to prompt the user Whether you need to adjust the aberration of each object. If not, no re-adjustment is required; if so, the object 807 is remapped such that the aberrations of the adjusted objects conform to the visual range. As shown in FIG. 8(c), the adjusted objects 807-809 are located within the range of the solid line N and the solid line F.
