Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of analog dial pointer picture compression storage method, shown in Figure 2, this method Including:
Step S11:Obtain the original pointer image data of PNG format;
Step S12:According to preset column processing sequence, respectively to each row pixel value in the original pointer image data Compression storage is sequentially carried out, compressed image data is obtained;
Wherein, compression storage is carried out to either rank pixel value in the original pointer image data, including:According to preset Row processing sequence to the row pixel value sequentially read and sequentially compression stores;
Wherein, if it is first row pixel value to read first non-zero pixels value and the row pixel value, phase is preserved The location of pixels answered;If it is identical and meet multiple continuous non-zero pixels values of preset condition to read pixel value, protect It deposits corresponding duplicate marking and repeats pixel quantity;After having read first non-zero pixels value of the row pixel value, if The pixel value that pixel value is zero is read, then forces the read operation for terminating the row pixel value, then jumps to next column pixel First non-zero pixels value of value, and preserve and redirect the pixel quantity that mark and this jump procedure are crossed over accordingly.
In the present embodiment, the preset column processing sequence can specifically include from the original pointer image data First is directed toward the sequence of tail row, or is arranged from the tail of the original pointer image data and be directed toward first sequence;The preset row Processing sequence can specifically include the sequence that first trip is directed toward from the tail row of the original pointer image data, or from described original The sequence of tail row is directed toward in the first trip of pointer image data.For example, Fig. 3 shows a kind of original pointer figure of specific PNG format As data, and the sequence of digital independent is specified in figure 3, specifically arranged according to from the first trip of tail row direction, from first direction tail Sequence sequentially read original pointer image data, that is, first read first pixel value according to sequence from left to right, so Read next column pixel value again afterwards, and so on, and when reading either rank pixel value, come according to sequence from top to bottom It is read out pixel value, this digital independent sequence is relatively suitble to the characteristic distributions of pixel value in pointer image, i.e. each column pixel Usually all there are the identical multiple pixels of pixel value in point, can make in this way when being read out to each column pixel value, The data compression to the row pixel value can be realized by way of recording duplicate marking and repeating pixel quantity, alleviating can wear The memory usage of carrying device.
Specifically, it is shown in Figure 4, it is described according to preset row processing sequence, which is sequentially read Sequentially compression stores, and may include:
Step S21:If it is first row pixel value to read first non-zero pixels value and the row pixel value, preserve Corresponding location of pixels.
If be pointed out that the preset column processing sequence be specially from the original pointer image data first It is directed toward the sequence of tail row, then the first row pixel value in above-mentioned steps S21 refers to first in the original pointer image data Pixel value;If the preset column processing sequence is specially to be directed toward the suitable of first from the tail of original pointer image data row Sequence, then the first row pixel value in above-mentioned steps S21 refers to the tail row pixel value in the original pointer image data.
In the present embodiment, the location of pixels of above-mentioned preservation is specific location letter of the respective pixel point in original pointer image Breath.For example, the pixel can be obtained by way of recording ranks coordinate information of the pixel in original pointer image Location of pixels namely the physical record pixel corresponding row serial number and the row serial number in original pointer image of point;In addition, by Row where considering the current pixel it is known that namely the current pixel be located on first row pixel, so at this time The information that can reflect the row where the pixel can only be recorded, you can deduce the pixel in original pointer image Specific location, for example the pixel and the distance between first trip pixel or tail row pixel can be recorded, it can by the distance To determine the serial number of the row where the pixel.
Step S22:If read with the different non-zero pixels value of adjacent pixel values, preserve the non-zero pixels value.
Step S23:If it is identical and meet multiple continuous non-zero pixels values of preset condition to read pixel value, It preserves corresponding duplicate marking and repeats pixel quantity.

Step S25:After having read first non-zero pixels value of the row pixel value, if it is zero to read pixel value Pixel value, then force to terminate the read operation of the row pixel value, then jump to first non-zero picture of next column pixel value Element value, and preserve and redirect the pixel quantity that mark and this jump procedure are crossed over accordingly.
It should be pointed out that the analog dial in the present embodiment may include the mould for being used to indicate the time on wearable device Quasi- dial plate, is used to indicate the analog dial of step number and is used to indicate the analog dial of electricity the analog dial for being used to indicate heart rate In any one or a few.Further it will be understood that above-mentioned steps S21 does not have sequentially between step S25 in execution Specific sequencing can be adjusted flexibly according to practical situations.
As it can be seen that the embodiment of the present invention when carrying out compression storage, is sequentially to carry out digital independent and compression storage, and And in first non-zero pixels value for reading first row pixel value, it will the corresponding location of pixels of the pixel value is recorded, this Sample can ensure subsequently to redraw pointer picture according to compressed image data;In addition, in the embodiment of the present invention, If it is identical and meet multiple continuous non-zero pixels values of preset condition to read pixel value, corresponding duplicate marking is preserved And pixel quantity is repeated, the size of data of compressed image data is advantageously reduced in this way;Secondly, a row picture is being read After first non-zero pixels value of element value, if reading the pixel value that pixel value is zero, pressure terminates the row pixel value Read operation, then jump to next column pixel value, can accelerate in this way compress storing process;Also, the embodiment of the present invention In compressing storing process, selects to skip numerical value as zero pixel value, it is not stored, can be also further reduced in this way The size of data of compressed image data.To sum up, the embodiment of the present invention can be effectively compressed pointer picture, reduce Memory usage of the pointer picture to wearable device.
Shown in Figure 5, the embodiment of the invention discloses a kind of to either rank picture in pointer picture compression storage method Plain value carries out the detailed process of compression storage, including:
Step S31:If it is first row pixel value to read first non-zero pixels value and the row pixel value, by phase The location of pixels answered is preserved into a byte.
Step S32:If read with the different non-zero pixels value of adjacent pixel values, by the non-zero pixels value preserve Into a byte.
Step S33:If reading multiple continuous non-zero pixels values that pixel value is 255, will repeat to mark accordingly Know and repeat pixel quantity and is preserved respectively into two different bytes.
It should be pointed out that due in the pointer image data of PNG format, in the corresponding pixel in pointer region There are the continuously distributed pixels that a large amount of pixel values are 255, so the present embodiment sets above-mentioned preset based on pixel value 255 Condition.It, only need to be to weighing accordingly after reading multiple continuous non-zero pixels values that pixel value is 255 in the present embodiment Multiple mark and repetition pixel quantity are preserved, without being preserved to pixel value 255, when subsequently according to this implementation When the compressed image data that example obtains redraws pointer picture, had recorded once reading in above-mentioned compressed image data Duplicate marking and accordingly repeat pixel data, then can directly uniquely determine out pixel value corresponding with the duplicate marking It is 255, thereby saves the memory headroom occupied due to storing pixel values 255, namely reduce compressed image data To the memory usage of wearable device.
Step S34:If read that pixel value is identical and pixel value be not 255 multiple continuous non-zero pixels values, Then corresponding non-zero pixels value is sequentially preserved into the byte of respective numbers respectively.
Step S35:After having read first non-zero pixels value of the row pixel value, if it is zero to read pixel value Pixel value, then force to terminate the read operation of the row pixel value, then jump to first non-zero picture of next column pixel value Element value, and mark will be redirected accordingly and preserved respectively to two different bytes with the pixel quantity that this jump procedure is crossed over In.
With reference to original pointer image data shown in Fig. 3 and corresponding reading order, pair with first row pixel It is worth relevant digital independent and compression storing process is specifically described.Specifically, being handled to first row pixel value When, it is continuously to read 4 pixel values 0 first, skips this 4 pixel values 0, without processing, then reads next picture Plain value 16, since the first non-zero pixels value and this row pixel value of 16 row pixel values of pixel value are first row pixels Value, so at this time preserving the location of pixels of the pixel value 16 to a byte, obtains " 00000010 ", and due to this Pixel value 16 is differed with adjacent pixel values, so also needing to preserve " 16 " into a byte at this time, is obtained " 00010000 "; And then " 117 " and " 225 " are successively read, and are preserved respectively into different bytes, obtain " 01110101 " and "11100001";Next 7 continuous non-zero pixels values that pixel value is 255 will be read, will be used to show to work as at this time It is preceding to there is the duplicate marking for repeating pixel value 255 and repeat accordingly in the preservation to two different bytes of pixel quantity 7;Again Then be to be successively read and preserve " 230 ", " 124 " and " 20 ", obtain " 11100110 ", " 01111100 " and "00010100";After having preserved " 20 ", continue to read the pixel value 0 after " 20 ", according to regulation above-mentioned, will force at this time Terminate the read operation for first row pixel value, then jumps to first non-zero pixels value 4 of secondary series pixel value, and It is preserved in different bytes for showing the picture for redirecting mark and this jump procedure and being crossed over there is currently skip operation Prime number amount 11.So far, with the relevant digital independent of first row pixel value and compression storing process all terminate, then start with The relevant digital independent of secondary series pixel value and compression storing process, particular content and the reading to first row pixel value and pressure Contracting storing process is similar, is no longer repeated herein.
Further, in the case where not made a significant impact on picture quality, in order to be further reduced compressed figure As data are to the occupancy of memory, following regulation is further made in the present embodiment:The duplicate marking and described redirect mark Being can be using the 1st binary digit and the Digital ID that is preserved of the 2nd binary digit in a byte;Also, To the process that any non-zero pixels value is preserved, including:If the non-zero pixels be worth the 1st two of corresponding binary number into Number on position processed and the 2nd binary digit is not all 0, then the non-zero pixels are worth the 1st two of corresponding binary number into Number on position processed and the 2nd binary digit is all adjusted to 0, the pixel value after being adjusted, then by the picture after the adjustment Element value is preserved into a byte.
That is, the number for playing the part of identified role in the present embodiment is specifically stored in the 1st and the 2nd in an octet In a binary digit, and low 2 of the corresponding binary number of pixel value all reset after be saved in an octet the In 3 to the 8th binary digits, in this way when the byte that will be used for preserving pixel value and the byte for preserving mark are stored to memory It waits, since both front and back complementarity makes the occupancy for further reducing memory.It can be seen that the present embodiment is to non-zero Before pixel value is stored, need first to carry out low two clearings processing to non-zero pixels.Herein, also in conjunction with being shown in Fig. 3 Original pointer image data and corresponding reading order, pair with the relevant digital independent of first row pixel value and compression deposit Storage process is specifically described.It is shown in Figure 6, it is assumed that the corresponding binary number of duplicate marking is in the present embodiment " 00000001 ", it is " 00000010 " to redirect the corresponding binary number of mark, then is based on above-mentioned compression storage rule, obtains successively Following binary number:After pixel value " 00010000 ", low two clearings after location of pixels " 00000101 ", low two clearings Pixel value " 11100000 ", duplicate marking " 00000001 ", repetition pixel number after pixel value " 01110100 ", low two clearings Measure " 00000111 ", it is low two reset after pixel value " 11100100 ", it is low two reset after pixel value " 01111100 ", low Two reset after pixel value " 00010100 ", redirect mark " 00000010 " and jump procedure leap pixel quantity "00001011".So far, the storage operation of the compression to the first row pixel value in original pointer image data is completed, and then It can continue to carry out sequentially compression storage operation to other remaining row pixel values based on above-mentioned compression storage rule, finally obtain The image data of compressed binary format corresponding with original pointer image data.
In above-mentioned compressed image data, first byte is 00000101, can first base in subsequent redrawing process The specific location of the first non-zero pixels point of first row pixel value is accurately determined out in the byte, namely determine first it is non- Then zero location of pixels reads next byte in compressed image data again, by the corresponding decimal data of the byte Above-mentioned first non-zero pixels position is written, thus reduction obtains first pixel;Then, continue to read next byte, The subsequent pixel of the pixel being currently just reduced is restored according to the content of the byte, for example, if the byte is Byte for recording pixel value then can fill in the word on the next pixel position for the pixel being currently just reduced Save corresponding decimal data;If the byte is for recording duplicate marking, not handling it first, then proceed to The repetition pixel quantity described in next byte is read, it accordingly can be a number of behind the pixel being currently just reduced Pixel position on fill in 255, wherein it is above-mentioned it is a number of with it is above-mentioned repeat pixel quantity it is identical;If the byte is to use Mark is redirected in record, then continues to read the pixel quantity that the jump procedure recorded in next byte is crossed over, is based on the picture Prime number amount determines the location of pixels of the first non-zero pixels value in secondary series pixel value, so far completes to first row pixel value In all non-zero pixels values reduction, and continue be unfolded secondary series pixel value reduction process, secondary series pixel value and after The reduction process for continuing the pixel value of other row is similar with reduction process disclosed above, is no longer repeated herein.It completes It is above-mentioned based on compressed image data fill in process after, the present embodiment is also needed based on not being filled out information at other 0 is filled on location of pixels, so far, completes and original pointer image data is redrawn.
It is understood that due to during obtaining above-mentioned compressed image data, the non-zero to storage is needed Pixel value carries out low two clearings processing, such that the follow-up image data for operating and obtaining that redraws is compared to original pointer figure As data, can be distorted, and this distortion phenomenon be due to caused by above-mentioned low two clearings processing, but, it is contemplated that it is low The variable quantity of corresponding non-zero pixels value is considerably less after two clearing processing, so it can thus be appreciated that the degree of above-mentioned distortion is also ratio It is lower, the actual displayed result of pointer image will not be caused apparent harmful effect namely it is above-mentioned redraw after obtained figure Picture and the difference very little between original pointer image so that user can not perceive above-mentioned difference during actual visual experience It is different, it is ensured that the visual experience of user is unaffected.
It should be pointed out that by above-mentioned compression storage rule, the present embodiment can obtain more outstanding compression ratio.With For 168 × 168 PNG pictures, before being compressed to the PNG pictures, single channel storage needed in save as 28224 words Section, after using above-mentioned compression storage rule, the memory needed for single channel storage is then reduced to 580 bytes, corresponding at this time Compression ratio is 580/28224=2.05%, it is possible thereby to which the memory pressure of wearable device is greatly reduced.
Shown in Figure 7, the embodiment of the invention discloses a kind of to either rank picture in pointer picture compression storage method Plain value carries out the detailed process of compression storage, including:
Step S41:If it is first row pixel value to read first non-zero pixels value and the row pixel value, by phase The location of pixels answered is preserved into a byte.
Step S42:If read with the different non-zero pixels value of adjacent pixel values, by the non-zero pixels value preserve Into a byte.
Step S43:If read, pixel value is identical and repetition pixel quantity is more not less than preset quantity threshold value A continuous non-zero pixels value then by corresponding duplicate marking and repeats pixel quantity and is preserved respectively to two different bytes In.
That is, the present embodiment be specifically according to repeat pixel quantity number set above-mentioned preset condition.It can manage Solution, above-mentioned preset quantity threshold value can specifically be set based on practical situations in the present embodiment, such as can be with It is set as 2 or 3 etc..
It should be pointed out that if only having one group of continuous non-zero pixels value to meet above-mentioned default item in either rank pixel value Part, then it is 255 that can give tacit consent to corresponding pixel value at this time, without being preserved to the pixel value.If any one row pixel value In there are the continuous non-zero pixels values of at least two groups to be satisfied by the preset condition, then by corresponding duplicate marking and repeat pixel When quantity is preserved respectively into two different bytes, further include:By corresponding non-zero pixels value preserve to except above-mentioned two not In third byte except same byte.For example, if occurring three groups of continuous non-zero pixels values in a row pixel value, it is corresponding Pixel value be respectively 250,255 and 253, then while preserving corresponding duplicate marking and repeating pixel quantity, also need Preserve corresponding pixel value 250,255 and 253.
Step S44:If read, pixel value is identical and repetition pixel quantity is less than the preset quantity threshold value Multiple continuous non-zero pixels values, then sequentially preserve corresponding non-zero pixels value into the byte of respective numbers respectively.
Step S45:After having read first non-zero pixels value of the row pixel value, if it is zero to read pixel value Pixel value, then force to terminate the read operation of the row pixel value, then jump to first non-zero picture of next column pixel value Element value, and mark will be redirected accordingly and preserved respectively to two different bytes with the pixel quantity that this jump procedure is crossed over In.
Further, the embodiment of the invention also discloses a kind of analog dial pointer pictures to redraw method, referring to Fig. 8 institutes Show, this method includes:
Step S51:It reads and utilizes the compressed of aforementioned disclosed analog dial pointer picture compression storage method storage Image data;
