Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.

Embodiments provide the processing method of a kind of video data, as it is shown on figure 3, include:

101, raw image data is received.

Wherein, raw image data includes at least a line view data.

Concrete, raw image data is that display device receives, data that display device shows that what network side sent need.

102, the row scaling coefficient of raw image data is determined.

Wherein, the view data of any row row scaling coefficient from center to two ends incrementally increases.

Concrete, owing to the distance of the center position of user to display device is different from the distance at the non-central location place of user to display device, so when the view data in the center of display device is identical with the view data size at non-central place, user watches the view data view data less than the center position of display device at non-central place.Therefore, in order to solve the problems referred to above, it is possible to after receiving raw image data, the row scaling coefficient of raw image data is adjusted.

Raw image data is when display device shows, the data of the center of raw image data need to show at the center position of display device, the data at the two ends place of raw image data, need to showing at the two ends place of display device, the data at many two ends show to end positions in the center of display device respectively from center to be raw image data.Owing to the distance of center position of user to display device incrementally increases with the two ends distance of user to display device, so, the view data that the display device that user watches shows arrives the view data at end positions place from the central position and progressively reduces, so when adjusting the row scaling coefficient of raw image data, it is necessary to each row view data of raw image data row scaling coefficient from center to two ends incrementally increases.

Exemplary, it is assumed that user display device center position just display device is watched in position, then user is L to the distance of the center position a of display device, user is to distance respectively L1, the L2 of non-central location place b, the c of display device.From Fig. 3, it is possible to finding out that distance L is less than distance L1 intuitively, distance L1 is less than distance L2.The view data size at the view data in the center of display device and non-central place concurrently there are user mutually and watches the phenomenon of the view data of non-central location place b, the c view data less than the center a of display device.After display device receives raw image data, if raw image data is 720P, owing to the corresponding diverse location to display device of the data of raw image data various location shows, assume, the center position a of the data correspondence display device at the a1 place of raw image data, is and need to show at the center position a of display device.The non-central location place b of the data correspondence display device at the b1 place of raw image data, is and need to show at the non-central location place b of display device.The non-central location place c of the data correspondence display device at the c1 place of raw image data, is and need to show at the non-central location place c of display device, as shown in Figure 5.So, in order to make user watch the view data of formed objects at the diverse location of display device, when raw image data being carried out row convergent-divergent and adjusting, the size of the view data at c1 place can be adjusted to the size of view data more than b1 place, the size of the view data at b1 place is adjusted to the size of the view data more than a1 place, and display device adjusts raw image data and need to first obtain the row scaling coefficient of each row, it is adjusted according to row scaling coefficient, so needing the row scaling coefficient from center to two ends of view data that display device obtains to incrementally increase.

Further, display device is after receiving raw image data, it is necessary to shown in the display device by this raw image data.Now need to adjust raw image data the size of this raw image data, in order to display device can show this raw image data, so display device needs first to determine the row scaling data of raw image data.

Concrete, display device determines that the method for the row scaling data of original image is specific as follows:

Can pre-set the row scaling coefficient of raw image data in the display device, and what the row scaling coefficient Shi Cong center of any row in the row scaling coefficient of the raw image data pre-set incrementally increased to two ends.Now display device is after receiving raw image data, it is possible to the row scaling coefficient of the raw image data this pre-set is defined as the row scaling coefficient of the raw image data received.Being in the above-mentioned methods, display device is without being calculated, it is only necessary to taken out by the row scaling coefficient of the original image prestored from memory element.

Or, display device, before determining the row scaling coefficient of raw image data, obtains the first distance.After obtaining the first distance, according to the first distance, it is determined that the row scaling coefficient of raw image data.

Wherein, the first distance is the vertical dimension that user arrives display device.

Concrete, position sensor can determine that the position of user, so when position sensor is arranged in the display device, display device can determine the position of user by position sensor, such that it is able to calculate the vertical dimension of user and display device.

Such as, as described in Figure 6, when user be positioned at a place, center of display device just to position time, display device can calculate user from the vertical dimension between a place, center of display device by position sensor.When user be positioned at the non-central location b place of display device just to position time, display device can calculate user from the vertical dimension between the non-central location b place of display device by position sensor.

It should be noted that display device can also obtain the first distance by additive method, for instance, user input the first distance, display device receives the first distance of user's input.It is, of course, also possible to be that the additive method present invention is without limitation.

Further, display device, after obtaining the first distance, determines row scaling coefficient specific as follows of each row of raw image data according to this first distance:

Concrete, according to the first distance, it is determined that the row scaling coefficient of raw image data includes: according to the first distance, search scaling coefficient mapping rule, it is determined that the row scaling coefficient of raw image data.

Wherein, scaling coefficient mapping rule pre-sets, the corresponding relation between the first distance and scaling coefficient.

It should be noted that display device is previously provided with scaling coefficient mapping rule.

Concrete, display device is after obtaining the first distance, the scaling coefficient mapping rule pre-set in it can be searched, when the scaling coefficient mapping rule within it pre-set finds the occurrence matched with the first distance, the row scaling coefficient of raw image data in this occurrence, can be obtained.

It should be noted that, for raw image data, the row scaling coefficient that the different rows of same column is corresponding can be identical, that is, for raw image data, the row scaling coefficient of all row of raw image data is identical, and now corresponding in scaling coefficient mapping rule row scaling coefficient is only the row scaling coefficient of any row of raw image data.Being display device after obtaining the first distance, by searching scaling coefficient mapping rule, get row scaling coefficient, this journey scaling coefficient is the row scaling coefficient of the data line of raw image data.Due to for raw image data, the row scaling coefficient that the different rows of same column is corresponding is identical, so, the row scaling coefficient of all row of raw image data is identical, thus display device using the row scaling coefficient of a line that obtains as the row scaling coefficient of each row in raw image data.

Certainly, for raw image data, the row scaling coefficient that the different rows of same column is corresponding also can differ, and the row scaling coefficient being different rows is not exclusively same.That is, for raw image data, the row scaling coefficient of all row of raw image data is incomplete same, and now, row scaling coefficient corresponding in scaling coefficient mapping rule can be the row scaling coefficient of every a line of raw image data.Display device is after obtaining the first distance, by searching scaling coefficient mapping rule, it is possible to get the row scaling coefficient of every a line of raw image data.

It should be noted that, when the row scaling coefficient of all row of raw image data is incomplete same, in display device, in scaling coefficient mapping rule, the line number corresponding to row scaling coefficient of every a line of the raw image data of storage is set in advance.If the line number that the raw image data that display device receives comprises is not the line number corresponding to row scaling coefficient of every a line of the raw image data of storage in scaling coefficient mapping rule set in advance, then the raw image data of reception can be zoomed in and out process by display device so that the line number comprised in the raw image data of the reception after process is identical with the line number of the raw image data corresponding to the row scaling coefficient of every a line of the raw image data of storage in scaling coefficient mapping rule set in advance.

Exemplary, scaling coefficient mapping rule stores the row scaling coefficient of every a line that row scaling data are the raw image data comprising 5 row view data corresponding for distance L in the display device.If the raw image data that display device receives includes 4 row view data.When display device determines the vertical dimension between user and display device for distance L by position sensor, display device searches scaling coefficient mapping rule according to distance L, and in scaling coefficient mapping rule, find out the row scaling coefficient of raw image data.Now, it is the row scaling coefficient of every a line of 5 row view data due to what find in scaling coefficient mapping rule, and the raw image data that display device receives only comprises 4 row view data.Now, the raw image data of reception can be amplified processing by display device, the raw image data after amplification is made to become including the raw image data of 5 row view data, such that it is able to using row scaling coefficient as the raw image data including 5 row view data of the row scaling coefficient that finds from scaling coefficient mapping rule.

Or, display device is after obtaining the first distance, it is possible to be calculated getting the row scaling coefficient of raw image data according to the first distance, without prestoring scaling coefficient mapping rule.Now display device needs first to obtain the second distance that adjustment region is corresponding, now according to the first distance, it is determined that before the row scaling coefficient of raw image data, also include: obtain the second distance that at least two adjustment region is corresponding.

Wherein, adjustment region is the region in display device except display centre region.Second distance is the distance that user arrives the presetted pixel unit in described adjustment region.The described presetted pixel unit of adjustment region described in any two is positioned at same a line.Described display centre region is set in advance, comprises the region at the display centre row pixel place of display device.

It should be noted that the display centre region of display device refers to the region at the central series pixel place of display device, it is possible to only include central series pixel, it is also possible to comprise other row pixels adjacent with central series pixel.Can need to change according to the actual viewing of user and set the pixel that this region comprises.Such as, this region is the central series pixel of display device and adjacent both sides pixel column thereof.In order to ensure that user watches the visual effect of view data, it is possible to arrange the pixel columns in the display centre region of display device be not more than display device display floater the total columns of pixel 1/10th.It is, of course, also possible to set the pixel column comprised in display centre region by other means, the present invention is without limitation.

When n is odd number, the central series pixel of display device is (the n+1)/2 row pixel of the display screen of display device.When n is even number, the central series pixel of display device is the n-th/2 row pixel or n-th/2+1 row pixel of the display screen of display device.Wherein, n is the total columns of pixel of the display screen of display device.

It should be noted that adjustment region also pre-sets.It is to say, in advance display device to be divided into different regions.And each adjustment region includes the pixel column of the non-display central series pixel of at least string.And the pixel column difference that difference adjustment region comprises.

It should be noted that pixel column refers to string pixel cell.Display device display raw image data is to be shown in the display screen of display device by raw image data.User watches display device and refers to that user watches the view data shown in the display screen of display device.Display screen includes multiple pixel cell.The string pixel cell comprised from top to end of display screen is considered as pixel column, and when making the display screen of display device, the distance between adjacent pixel column sets.

Concrete, after display device can determine the position of user by position sensor, the position of the user distance from the presetted pixel unit in each adjustment region can be calculated according to the position of user, so that it is determined that go out the second distance that each adjustment region is corresponding.

Further, display device can also directly calculate second distance according to the first distance, without passing through position sensor, the second distance that now display device obtains at least two adjustment region corresponding includes: according to described first distance, and the distance that at least two adjustment region is interregional with display centre, determine the second distance that at least two adjustment region is corresponding respectively.

Concrete, due to the distance between two row pixels adjacent in display screen it has been determined that, and display device can determine that in central series pixel and is positioned at the pixel cell of same a line with the presetted pixel unit of adjustment region, it can be determined that go out in central series pixel and the presetted pixel unit of adjustment region is positioned at the pixel cell of same a line from the distance between the presetted pixel unit of each adjustment region, and then display device can according in the first distance and central series pixel and the presetted pixel unit of adjustment region be positioned at the pixel cell of same a line from the distance between the presetted pixel unit of each adjustment region, determine the second distance that each adjustment region is corresponding.It is the distance between the presetted pixel unit determining user and each adjustment region.

It should be noted that when adjustment region comprises at least two row pixels, it is possible to choose the pixel cell in either rank as presetted pixel unit.In order to ensure to calculate more accurately second distance, it is possible to all choose the pixel cell in the i-th row pixel of each adjustment region in each adjustment region as presetted pixel unit.Wherein, i=1,2 ... m.Wherein, m is the sum of the pixel column that adjustment region comprises.Presetted pixel unit in adjustment region can be the center pixel unit in the i-th row pixel column of each adjustment region, it is possible to being other pixel cells, the present invention is without limitation.However, to ensure that the row scaling coefficient obtained is accurate, it is necessary to the presetted pixel unit of each adjustment region is arranged on same a line, in order to calculate second distance more accurately.

Further, in order to improve the visual effect of user better, it is possible to the pixel column except display centre region comprised of display device is divided in adjustment region uniformly.In this manner it is ensured that calculate second distance more accurately, thus improving the visual effect of user better.

Exemplary, as it is shown in fig. 7, have 4 adjustment region, respectively the 1st adjustment region, the 2nd adjustment region, the 3rd adjustment region and the 4th adjustment region in the display device.And each adjustment region includes 4 row pixel columns.As such, it is possible to using the center pixel unit in the 2nd row pixel in each adjustment region as presetted pixel unit.

As above, described in example, there are 4 adjustment region, respectively the 1st adjustment region, the 2nd adjustment region, the 3rd adjustment region and the 4th adjustment region in the display device.And using the center pixel unit in each adjustment region as presetted pixel unit.Now, display device is after determining that the first distance is for P0, can determine that presetted pixel unit in central series pixel and in each adjustment region is with the distance between the presetted pixel unit in the pixel cell of a line and each adjustment region, is the distance between the center pixel unit in the center pixel unit and each adjustment region determining central series pixel according to the distance between adjacent two row pixels.Assume that the distance P1 between the center pixel unit in the center pixel unit of central series pixel and the 1st adjustment region and the 2nd adjustment region determined by display device, the distance P2 between the center pixel unit in the center pixel unit of central series pixel and the 3rd adjustment region and the 4th adjustment region determined by display device, as shown in Figure 8, then display device can according to the first distance P0 determined, the distance P1 between center pixel unit in the center pixel unit of central series pixel and each adjustment region, P2, calculate the distance between the center pixel unit in user and each adjustment region, it is and calculates the 1st adjustment region and second distance corresponding to the 2nd adjustment region is (P0²+P1²)^1/2, the 3rd adjustment region and second distance corresponding to the 4th adjustment region are (P0²+P2²)^1/2。

It should be noted that second distance corresponding to adjustment region along with adjustment region and display centre arrange between the increase of distance and increase.Wherein, the distance between adjustment region and display centre row refers in central series pixel and the presetted pixel unit of adjustment region is positioned at the pixel cell of same a line from the distance between the presetted pixel unit of adjustment region.Be the distance that in the central series pixel in display centre region and adjustment region presetted pixel unit is positioned between the pixel cell of same a line and the presetted pixel unit of adjustment region more big, then the second distance that adjustment region is corresponding is more big.So, second distance corresponding to display device calculates adjustment region incrementally increases from the center of display device to two ends.

It should be noted that the second distance that display device obtains at least two adjustment region corresponding can also use additive method, the present invention is without limitation.

Further, after the second distance that each adjustment region is corresponding determined by display device, display device is according to the first distance, determine that the row scaling coefficient of raw image data includes: according to the first distance, the second distance that at least two adjustment region is corresponding, obtains the row scaling coefficient of display device.According to the corresponding relation between raw image data and described display device, the row scaling coefficient of display device is determined the row scaling coefficient of raw image data.

That is, display device is after obtaining the first distance and second distance, it is the vertical dimension obtaining between user and display device, and user and each adjustment region of display device in presetted pixel unit between distance after, can according to this first distance and second distance, determine the row scaling coefficient of display device, be the row scaling coefficient determining that display device difference adjustment region is corresponding.After obtaining row scaling coefficient, it is possible to according to the corresponding relation between raw image data and display device, each row scaling coefficient of the display device of acquisition is determined each row scaling coefficient of raw image data.

Exemplary, as shown in Figure 9, it is assumed that have 4 adjustment region, respectively the 1st adjustment region, the 2nd adjustment region, the 3rd adjustment region and the 4th adjustment region in the display device.And each adjustment region includes 4 row pixel columns.And the center position a of the data correspondence display device at the a1 place of raw image data, it is and need to show at a place, center of display device.1st adjustment region b place of the data correspondence display device at the b1 place of raw image data, is and need to show at the 1st adjustment region b place of display device.2nd adjustment region c place of the data correspondence display device at the c1 place of raw image data, is and need to show at the 2nd adjustment region c place of display device.3rd adjustment region d place of the data correspondence display device at the d1 place of raw image data, is and need to show at the 3rd adjustment region d place of display device.4th adjustment region e place of the data correspondence display device at the e1 place of raw image data, is and need to show at the 4th adjustment region e place of display device.Display device is after the row scaling coefficient obtained in display device in different adjustment region according to the first distance and second distance, can according to the corresponding relation of raw image data Yu display device, using the row scaling coefficient as raw image data various location of the row scaling coefficient in zones of different in display device.It is the row scaling coefficient at a place, center of the display device row scaling coefficient as the a1 place data of raw image data, using the row scaling coefficient at the 1st adjustment region b place row scaling coefficient as the b1 place data of raw image data, using the row scaling coefficient at the 2nd adjustment region c place row scaling coefficient as the c1 place data of raw image data, using the row scaling coefficient at the 3rd adjustment region d place row scaling coefficient as the d1 place data of raw image data, using the row scaling coefficient at the 4th adjustment region e place row scaling coefficient as the e1 place data of raw image data.

It should be noted that, after display device receives raw image data, the size of raw image data can be known, the display device size according to its display size, determine the corresponding relation between raw image data and display device, it is the corresponding position with display device of each row and column data determining raw image data, may thereby determine that out the region at each row and column data place of raw image data.Such that it is able to after determining the row scaling data of display device, according to this corresponding relation, each row scaling coefficient is determined each row scaling coefficient of raw image data.

Further, display device can pre-set the corresponding relation between raw image data and display device, so, display device is after obtaining the row scaling coefficient of display device, according to the corresponding relation between default raw image data and display device, the row scaling coefficient correspondence of display device can be defined as the row scaling coefficient of raw image data.

When display device pre-sets the corresponding relation between raw image data and display device, it is necessary to the form of raw image data in the corresponding relation between raw image data and display device is preset out.If the form of the raw image data that display device receives is if not the form of raw image data in corresponding relation between raw image data and display device, then need display device first will receive the form of raw image data in the corresponding relation that raw image data is converted between raw image data and display device.Such as, in corresponding relation between raw image data and display device, the form of raw image data is 720P (Progressivescan, progressive scan), if the form of the raw image data that display device receives is 480P, then display device needs the raw image data of reception is first converted to form is 720P raw image data.

It should be noted that 720P is a kind of video display format.P represents progressive scan, and 720 represent that line direction has 720 scanning lines, and the screen resolution of usual 720P is 1280*720.

Further, described according to described first distance, the second distance that at least two adjustment region is corresponding, the row scaling coefficient obtaining display device includes: according to the second distance that described first distance and at least two adjustment region are corresponding, utilize formula m=L_n/L₀, obtain the row scaling coefficient of display device.

Wherein, L_nRepresent the second distance that the n-th adjustment region is corresponding, n=1,2,3 ..., k, wherein k is the number of the adjustment region divided；L₀Representing the first distance, m represents the row scaling coefficient of display device.

It is to say, display device obtains the ratio between second distance and the first distance, using this ratio row scaling coefficient as display device.

Further, in order to adjust raw image data more accurately, when arranging central display area and adjustment region, it is possible to only using display centre row pixel as central display area, using other non-central row pixels of every string as an adjustment region.Being, each pixel column of the display screen of display device is all as a region, and viewing area centered by display centre row pixel, using other either rank pixel columns all as adjustment region.

It is to say, when display centre region only comprises central series pixel, display device can using each each column pixel except central series pixel as an adjustment region.Such as, if display device has n row pixel, when n is even number, then can using the n-th/2 row pixel column as display centre region, when n is odd number, then can using (n+1)/2 row pixel column as display centre region.And using the i-th row pixel as i-th adjustment region.I=1,2,3 ... n, and i ≠ n/2.Now display device need to calculate the second distance of its correspondence for each adjustment region.And second distance corresponding to this n-1 adjustment region increases along with the increase of the distance between the presetted pixel of adjustment region and the central series pixel in display centre region.
