In the embodiment of the invention, according to the detected operation gesture and the first display position of the OSD image on the display screen, the second display position of the OSD image on the display screen after the position of the OSD image is changed from the first display position is determined. Wherein the first display position and the second display position are not the same position.
For example, if the first display position is the lower right corner of the display screen 10 and the operation gesture is a leftward sliding, it is determined that the second display position of the OSD image 20 is the lower left corner of the display screen 10.

For example, the second display position of the OSD image 20 is the lower left corner of the display screen 10, and when the target fusion image obtained by fusing the OSD image 20 and the display image is displayed on the display screen 10, as shown in fig. 7, it can be seen that the OSD image 20 is displayed on the lower left corner of the display screen 10, and the display area except for the lower left corner of the display screen 10 displays the display image.
Alternatively, if the first display position is the upper right corner of the display screen 10 and the operation gesture of the OSD image 20 displayed for the first display position on the display screen 10 is sliding downward, the display position of the OSD image 20 may be switched from the upper right corner of the display screen 10 to the lower right corner of the display screen 10.
The problem of inconvenient operation when the user uses the OSD image 20 to perform relevant settings can be solved by quickly switching the display position of the OSD image 20 on the display screen 10 through gesture operation. For example, for a large-sized display device, the height of the display device is high, and if the OSD image 20 is fixedly displayed on the upper right corner of the display screen 10, it is difficult for a short user to perform related settings through the OSD image 20 displayed on the upper right corner of the display screen 10.
In the embodiment of the invention, after the OSD image is called, the display position of the OSD image on the display screen is quickly and conveniently changed by using the operation gesture, namely the display position of the OSD image on the display screen is changed from the first display position to the second display position, so that the problem of inconvenient operation when a user uses the OSD image to carry out relevant setting is solved, and the operation convenience of the user is improved.
Example two
Referring to fig. 8, a specific flowchart of an image display control method according to an embodiment of the present invention is shown, which specifically includes the following steps:
In the embodiment of the present invention, in order to avoid mistakenly recognizing the operation gesture of the user to switch the display position of the OSD image 20, it is necessary to determine in advance whether to turn on the gesture recognition function of the display device.
First, it is determined whether a gesture recognition trigger operation for the OSD image 20 displayed at the first display position on the display screen 10 is detected, and in particular, the gesture recognition trigger operation may be detected by a detection component in the display apparatus.
When the gesture recognition triggering operation of the OSD image 20 displayed for the first display position on the display screen 10 is detected, step 802 is executed, and when the gesture recognition triggering operation of the OSD image 20 displayed for the first display position on the display screen 10 is not detected, the present scheme is not executed until the gesture recognition triggering operation of the OSD image 20 displayed for the first display position on the display screen 10 is detected.
Specifically, step 801 includes sub-steps S11 and S12:
a substep S11, determining that a gesture recognition trigger operation for the OSD image displayed at the first display position on the display screen is detected when a duration in which the infrared light is not received by at least one infrared receiving unit is greater than or equal to a preset duration, in a plurality of infrared detection devices corresponding to the first display position of the OSD image;
in the sub-step S12, in the plurality of infrared detection devices corresponding to the first display position of the OSD image, when all the infrared receiving units receive the infrared light, or a time period during which any one or more of the infrared receiving units do not receive the infrared light is shorter than the preset time period, it is determined that the gesture recognition trigger operation for the OSD image displayed at the first display position on the display screen is not detected.
In the embodiment of the present invention, the detection assembly includes a plurality of infrared detection devices corresponding to the display position of each OSD image 20, and each infrared detection device includes an infrared transmitting unit and an infrared receiving unit that are oppositely disposed.
When the gesture recognition function of the display device needs to be turned on, a user may place a finger at a position of the OSD image 20 displayed at the first display position on the display screen 10, and then, in a plurality of infrared detection devices corresponding to the first display position of the OSD image 20, one or more infrared receiving units may not receive infrared light emitted by a corresponding infrared emitting unit, and when a duration in which the infrared receiving unit does not receive the infrared light is greater than or equal to a preset duration, it is determined that the gesture recognition trigger operation for the OSD image 20 displayed at the first display position on the display screen 10 is detected.

When the user does not place a finger at the position of the OSD image 20 displayed at the first display position on the display screen 10, all the infrared receiving units in the plurality of infrared detecting devices corresponding to the first display position of the OSD image 20 receive the infrared light, and it is determined that the gesture recognition trigger operation for the OSD image 20 displayed at the first display position on the display screen 10 is not detected; or, if the time that the user places at the position of the OSD image 20 displayed at the first display position on the display screen 10 is short, in the plurality of infrared detection devices corresponding to the first display position of the OSD image 20, the duration that any one or more infrared receiving units do not receive infrared light is less than the preset duration, it is determined that the gesture recognition trigger operation for the OSD image 20 displayed at the first display position on the display screen 10 is not detected.
In the embodiment of the invention, when the gesture recognition triggering operation of the OSD image 20 displayed for the first display position on the display screen 10 is detected, the gesture recognition function of the display device is turned on to detect the gesture operation of the user through the detection component.
In the embodiment of the present invention, after the gesture recognition function of the display device is turned on, the OSD image 20 displayed at the first display position on the display screen 10 is blurred, that is, the transparency of the OSD image 20 displayed at the first display position on the display screen 10 is increased, and at the same time, the display screen 10 is controlled to display the position change indication icon of the OSD image 20, where the position change indication icon is used to indicate the moving direction corresponding to the operation gesture.

In the embodiment of the present invention, after the gesture recognition function of the OSD image and the turn-on display device is invoked, the operation gesture of the OSD image 20 displayed for the first display position on the display screen 10 is determined through the plurality of infrared detection devices corresponding to the first display position of the OSD image 20. Specifically, the operation gesture of the OSD image 20 displayed for the first display position on the display screen 10 is determined according to the distribution position of each infrared receiving unit that does not receive the infrared light and the time sequence of each infrared receiving unit that does not receive the infrared light.
For example, the first display position of the OSD image 20 on the display screen 10 is the lower right corner of the display screen 10, the initial position of the finger is located on the horizontal line where the infrared emitting unit a18 and the infrared receiving unit B18 are located, and the horizontal line where the infrared emitting unit a28 and the infrared receiving unit B28 are located, therefore, in the process of the user sliding the finger to the left, the infrared receiving unit B28 does not receive the infrared light first, then, the infrared receiving unit B27 does not receive the infrared light any more, and during the sliding of the finger, the infrared receiving unit B18 is in a state of not receiving the infrared light all the time, according to the distribution positions of the infrared receiving unit B28 and the infrared receiving unit B27 (the infrared receiving unit B27 is located at the left side of the infrared receiving unit B28), and the time sequence in which the infrared receiving unit B28 and the infrared receiving unit B27 do not receive the infrared light, the operation gesture of the OSD image 20 displayed for the first display position on the display screen 10 is determined to be leftward sliding; alternatively, the initial position of the finger is located at a horizontal line where the infrared transmitting unit A18 and the infrared receiving unit B18 are located, and the infrared transmitting unit a28 and the infrared receiving unit B28 are located on a horizontal line, so that, during the process of sliding the finger upward, the infrared receiving unit B18 does not receive the infrared light first, and then the infrared receiving unit B17 does not receive the infrared light, during the sliding of the finger, the infrared receiving unit B28 is always in a state of not receiving infrared light, according to the distribution positions of the infrared receiving unit B18 and the infrared receiving unit B17 (the infrared receiving unit B17 is located at the upper side of the infrared receiving unit B18), and the time sequence in which the infrared receiving unit B18 and the infrared receiving unit B17 do not receive the infrared light, the operation gesture of the OSD image 20 displayed for the first display position on the display screen 10 is determined to be a swipe up.
This step is similar to the step 102 in the first embodiment, and is not described herein again.
In the embodiment of the present invention, as shown in fig. 9, after the SOC chip draws an OSD image, the OSD image is sent to the FPGA chip, the FPGA chip stores the OSD image in the storage module, and the pixel format of the OSD image is 1920 × 1080.
The storage capacity of the storage module is 4Gb, Row is equal to 15, Column is equal to 10, the bank in the storage module is divided into two parts, including banks 0 to 7, the OSD image is stored in the first address starting from { 15'd 0, 10'd 0} of any bank, and then the FPGA chip reads the OSD image from the storage module.
The Memory module may be a DDR4(Double data Rate SDRAM, Double data Rate dynamic random access Memory) actually, and is connected to the FPGA chip through an MIG (Memory Interface Generator) IP core, specifically, one end of the MIG IP core is connected to an Interface of the DDR4, and the other end of the MIG IP core is interconnected to an AXI (advanced extensible Interface) of the FPGA chip, and based on the MIG IP core, the FPGA chip may store an OSD image in the DDR4, and accordingly, based on the MIG IP core, the FPGA chip may also read the OSD image from the DDR 4.
Because the interface transmission protocol between the FPGA chip and the timing controller requires that the pixel format of transmission is 480 × 4320, and the pixel format of the actual OSD image is 1920 × 1680, the format conversion of the OSD image is required, the OSD image is split into N OSD sub-images with the specified format, and correspondingly, the format conversion of the display image is also required, and the display image is split into M display sub-images with the specified format. Wherein M is a positive integer greater than N, and N is a positive integer greater than 1.
Specifically, M is equal to 16, N is equal to 4, and as shown in fig. 9, the format conversion is performed on the display image, the display image is split into 16 display sub-images with a specified format along the column direction, the pixel format of the display image is 7680 × 4320, and the specified format means that the number of pixels in the row direction and the column direction is 480 and 4320 respectively, that is, the pixel format of each display sub-image is 480 × 4320.
Correspondingly, format conversion is performed on the OSD image by splitting the OSD image into 4 parts along the column direction, wherein the pixel format of each part is 480 × 1080, and then, from line 1081 to line 4320, invalid data is filled in, for example, invalid data 0 is used for filling, so that 4 OSD sub-images with the pixel format of 480 × 4320 are obtained.
In the embodiment of the invention, according to the second display position, N display sub-images with the specified format are selected from the M display sub-images with the specified format as target display sub-images.
For example, M is 16, N is 4, the display image includes 16 display sub-images with a pixel format of 480 × 4320, and from left to right, the display sub-image L1, the display sub-image L2, the display sub-image L3, the display sub-image L4, the display sub-image L5, the display sub-image L6, the display sub-image L7, the display sub-image L8, the display sub-image R1, the display sub-image R2, the display sub-image R3, the display sub-image R4, the display sub-image R5, the display sub-image R6, the display sub-image R7, and the display sub-image R8 are respectively, as shown in fig. 9, according to the second display position, from the 16 display sub-images with the designated format, 4 display sub-images.
When the second display position of the OSD image 20 is the right side (including the upper right corner and the lower right corner) of the display screen 10, the rightmost 4 display sub-images are taken as target display sub-images, that is, the display sub-image R5, the display sub-image R6, the display sub-image R7, and the display sub-image R8 are taken as target display sub-images; when the second display position of the OSD image 20 is the left side (including the top left corner and the bottom left corner) of the display screen 10, the leftmost 4 display sub-images are the target display sub-images, that is, the display sub-image L1, the display sub-image L2, the display sub-image L3, and the display sub-image L4 are the target display sub-images; when the second display position of the OSD image 20 is the center position of the display screen 10, the middle 4 display sub-images are set as target display sub-images, that is, the display sub-image L7, the display sub-image L8, the display sub-image R1, and the display sub-image R2 are set as target display sub-images.
And 808, fusing the OSD sub-image and the target display sub-image according to the second display position to obtain a partially fused image.
In the embodiment of the invention, the OSD sub-image and the target display sub-image are fused according to the second display position to obtain a partial fused image.
Specifically, in the first case, step 808 includes sub-steps S21 to S24:
substep S21, when the second display position is located at the upper side of the display screen, performing effective line counting on the input time sequence corresponding to the target display sub-image to obtain a first count value;
sub-step S22, determining the OSD sub-image as a first effective image when the first count value is less than or equal to a first setting value;
sub-step S23, determining the target display sub-image as a second effective image when the first count value is greater than the first setting value;
and a substep S24, merging the first effective image and the second effective image to obtain the partially fused image.
When the second display position of the OSD image 20 is the upper side (including the upper left corner and the upper right corner) of the display screen 10, performing active line counting on the input timing sequence corresponding to the target display sub-image to obtain a first count value count 1; if the pixel formats of the target display sub-image and the OSD sub-image are 480 × 4320, the first setting value is 1080, when the first count value count1 is less than or equal to 1080, the OSD sub-image is determined to be the first effective image, when the first count value count1 is greater than 1080, the target display sub-image is determined to be the second effective image, and the first effective image and the second effective image are merged to obtain a partially fused image.
Since the OSD subimages are invalid data from line 1081 to line 4320, when the OSD subimages are merged with the target display subimages, the target display subimages are used as valid images from line 1081, which does not affect the integrity of the OSD subimages, and the OSD images can be completely displayed when the target merged image is displayed subsequently.
Specifically, in the second case, step 808 includes sub-steps S25 to S28:
substep S25, when the second display position is located at the lower side of the display screen, performing effective line counting on the input time sequence corresponding to the target display sub-image to obtain a second count value;
a sub-step S26 of determining the target display sub-image as a third effective image when the second count value is less than or equal to a second set value;
sub-step S27, determining the OSD sub-image as a fourth effective image when the second count value is greater than the second setting value;
and a substep S28, merging the third effective image and the fourth effective image to obtain the partially fused image.
When the second display position of the OSD image 20 is the lower side (including the lower left corner and the lower right corner) of the display screen 10, performing active line counting on the input timing sequence corresponding to the target display sub-image to obtain a second count value count 2; if the pixel formats of the target display sub-image and the OSD sub-image are 480 × 4320, the second setting value is 3240, when the second count value count2 is less than or equal to 3240, the target display sub-image is determined to be the third effective image, when the second count value count2 is greater than 3240, the OSD sub-image is determined to be the fourth effective image, and the third effective image and the fourth effective image are merged to obtain a partial fusion image. The fusion mode does not influence the integrity of the OSD sub-images, and the OSD images can be completely displayed when the target fusion images are displayed subsequently.
In a third case, when the second display position is located at the center of the display screen, performing effective line counting on the input time sequence corresponding to the target display sub-image to obtain a third count value; and when the third count value is less than or equal to a third set value, determining the target display sub-image as a fifth effective image, when the third count value is greater than the third set value and less than or equal to a fourth set value, determining the OSD sub-image as a sixth effective image, when the third count value is greater than the fourth set value, determining the target display sub-image as a seventh effective image, and merging the fifth effective image, the sixth effective image and the seventh effective image to obtain a partial fusion image.
If the pixel format of the target display sub-image and the OSD sub-image is 480 × 4320, the third setting value is 1620, and the fourth setting value is 2700.
And step 809, fusing the partial fusion image with the display sub-images in the display image except the target display sub-image to obtain the target fusion image.
In the embodiment of the present invention, as shown in fig. 9, the display sub-images in the display image except for the target display sub-image are 12 display sub-images, and the target fusion image is obtained by merging the partial fusion image and the remaining 12 display sub-images.
This step is similar to the step 104 in the first embodiment, and is not described herein again.
