For the convenience of description, the following will temporarily assume that the above-mentioned mechanism for adjusting the visual content VC is executed by the electronic device 110 in FIG. 1 , but it is not intended to limit possible implementations of the present invention.

In the embodiment of the present invention, the processor 114 can access the modules and program codes recorded in the storage circuit 112 to implement the method for compensating for visual field defect proposed by the present invention, the details of which are described in detail below.

Please refer to FIG. 2 , which is a flowchart of a method for compensating for visual field defect according to an embodiment of the present invention. The method of this embodiment can be executed by the electronic device 110 in FIG. 1 , and the details of each step in FIG. 2 will be described below in conjunction with the elements shown in FIG. 1 .

First, in step S210, the processor 114 may obtain a visual field map of the wearer, and identify the visual field defect area in the visual field map. Generally speaking, the visual field map of the wearer can be generated by relevant medical personnel performing visual field detection on the wearer with related instruments (eg, Humphrey perimeter), and can be stored by the wearer or other relevant personnel in a specific storage accessible by the processor 114 . in a location (eg, a cloud database or storage circuit 112 ). Based on this, the processor 114 can directly access the above-mentioned specific storage location to obtain the wearer's visual field, but it is not limited to this.

Please refer to FIG. 3 , which is a view diagram according to an embodiment of the present invention. In this embodiment, it is assumed that the visual field map 300 is the visual field map of the wearer of the head-mounted display 120, wherein the horizontal axis corresponds to the wearer's lateral viewing angle, the vertical axis corresponds to the wearer's longitudinal viewing angle, and the origin O1 corresponds to The center point of the wearer's field of vision. In the visual field map 300 , each point shown has a light sensitivity value (unit: dB), which can be used to represent the wearer's light sensitivity at a corresponding viewing angle.

In the embodiment of the present invention, it is assumed that a lower light sensitivity value corresponds to a darker color. Therefore, it can be seen from FIG. 3 that there are multiple pieces of weak light sensitivity in the lower left and upper left of the center point of the wearer's visual field. field of view.

In one embodiment, after the processor 114 obtains the wearer's visual field map, it can identify one or more light sensitivity values therein that are lower than a predetermined threshold value (which can be determined by the designer according to needs), The area formed by these light sensitivity values was defined as the visual field defect area. Taking FIG. 3 as an example, if the light sensitivity values in the areas 310 and 320 are both lower than the above-mentioned preset threshold, the processor 114 can accordingly define the areas 310 and 320 as the wearer's visual field defect area, but it is not limited thereto. . In another embodiment, the processor 114 can obtain the information of the visual field defect area at the same time when obtaining the wearer's visual field map.

Afterwards, in step S220, the processor 114 may obtain the visual content VC, and identify a specific area corresponding to the visual field defect area in the visual content VC. As mentioned earlier, the visual content VC may be obtained by photographing the landscape in front of the wearer by the front lens 122 of the head mounted display 120, but it is not limited thereto.

In one embodiment, the processor 114 may obtain the first relative position between the visual field defect region (ie, the regions 310 , 320 ) and the center point of the visual field (ie, the origin O1 ). Afterwards, the processor 114 can obtain the gaze center point of the wearer on the visual content VC, and define a specific area in the visual content VC according to the first relative position and the gaze center point, wherein the second point between the specific area and the gaze center point is The relative position corresponds to the first relative position between the visual field defect area and the center point of the visual field, and each specific area may include a plurality of specific pixels. In one embodiment, the wearer's gaze center point can be tracked by a technique such as eye tracking to track the movement of the eyeball, and then the wearer's gaze center point can be calculated.

For ease of understanding, the following description will be supplemented with FIGS. 4A to 4B , wherein FIG. 4A is a schematic diagram of visual content according to an embodiment of the present invention, and FIG. 4B is a schematic diagram of obtaining a specific area corresponding to the visual field defect area.

In FIG. 4A , the visual content VC is, for example, the front landscape captured by the front lens 122 . In FIG. 4B , assuming that the wearer has a gaze center point 405 when viewing the visual content VC, the processor 114 can define specific regions 410 and 420 in the visual content VC according to the above-mentioned first relative position and gaze center point 405 .

In one embodiment, the processor 114 may regard the gaze center point 405 as the origin O1 of FIG. 3 (ie, the center of the field of view), and then according to the relative position between the area 310 and the origin O1 in FIG. A specific area 410 corresponding to the area 310 is identified in FIG. 3 , wherein the relative position between the specific area 410 and the gaze center point 405 corresponds to the relative position between the area 310 and the origin O1 in FIG. 3 . Similarly, the processor 114 can further identify a specific area 420 corresponding to the area 320 in the visual content VC according to the relative position between the area 320 and the origin O1 in FIG. 3 , wherein the specific area 420 is between the gaze center point 405 The relative position of corresponds to the relative position between the region 320 and the origin O1 in FIG. 3 .

After identifying the specific areas 410 and 420 corresponding to the visual field defect area, in step S230, the processor 114 may adjust the brightness value of each specific pixel according to the corresponding light sensitivity value to adjust the visual content VC.

For example, it is assumed that a first position in the area 310 has a first light sensitivity value, and the specific area 410 has a first specific pixel whose position corresponds to the above-mentioned first position in the area 310, and further corresponds to the above-mentioned first pixel The first light sensitivity value for the location. Afterwards, the processor 114 may obtain the original luminance value of the first specific pixel (ie, the original luminance value of the first specific pixel), and increase the original luminance value to the first luminance value according to the first light sensitivity value.

In one embodiment, the first luminance value may be expressed as the sum of the original luminance value and a luminance difference value, and the luminance difference value may be negatively related to the first light sensitivity value. That is, the lower the first light sensitivity value corresponding to the first specific pixel in the area 310 is, the higher the above-mentioned luminance difference value is, and vice versa.

In short, the processor 114 can increase the brightness value of each specific pixel in the specific area 410, 420 according to the light sensitivity value of the corresponding position, so that the specific area 410, 420 is in the adjusted visual content VC' may have higher brightness, but may not be limited to this.

As shown in FIG. 4C , in the adjusted visual content VC′, since the specific regions 410 ′ and 420 ′ (which are the specific regions 410 and 420 after the brightness value has been increased, respectively) have higher brightness, it is possible to have The wearer in the visual field-deficient area shown in FIG. 3 smoothly observes the content in the specific areas 410' and 420'. In addition, since the visual content VC is the landscape in front of the wearer, the wearer can view the complete front landscape by viewing the adjusted visual content VC' without being limited by the defected area of his own visual field.

As can be seen from the above, the present invention can adjust the visual content by increasing the brightness value of a specific area corresponding to the visual field defect area in the visual content, so that the wearer with the visual field defect area will not be affected by the adjusted visual content when viewing the adjusted visual content. Defects in their own visual field and unable to appreciate the complete visual content (such as the landscape ahead).
