Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The application provides a digital clock display method, which can be applied to a processor of a wearable product with an AOD mode, as shown in fig. 1, and specifically comprises the following steps:
Step S100: a plurality of character images of a digital clock image to be generated are acquired.
Step S102: the transparency and the first pixel value of each first pixel point of each character image are obtained.
Step S104: and acquiring a background image of the digital clock image to be generated and a second pixel value of each second pixel point of the background image.
Step S106: and fusing the background image with the plurality of character images according to the transparency of each first pixel point, the first pixel value and the second pixel value of each second pixel point to obtain a digital clock image.
In step S100, the plurality of character images of the digital clock image to be generated represent character images of the digital clock image to be generated according to the current time, for example, the current time is twelve thirty minutes, and then the plurality of character images of the digital clock image to be generated acquired in step S100 are character "1", character "2", character "in" 12:30 ": "character" 3", and character" 0", wherein all character images required for the digital clock including numerals 0 to 9 and characters": of course, besides the numbers 0-9, the scheme can also include greek numbers from one to nine, chinese uppercase and other characters, so as to be directly determined when the step S100 is executed later. After step S100 is performed to obtain a plurality of character images of the digital clock image to be generated, step S102 may be performed.
In step S102, the present scheme obtains the transparency of each first pixel point and the first pixel value of each first pixel point of each of the plurality of character images determined in step S100, for example, according to the foregoing example, when the current time is twelve points and thirty points, the present scheme obtains the characters "1", the characters "2", and the characters ": transparency of each first pixel point and first pixel value of each character of "," character "3" and "0". The transparency of each first pixel point of each character image and the first pixel value can be determined and stored in advance, and can be stored in a register of the device. After the transparency and the first pixel value of each first pixel point of each character image are obtained in step S102, step S104 may be performed.
In step S104, the scheme obtains a background image of the digital clock image to be generated and obtains a second pixel value of each second pixel point of the background image, where each second pixel point of the background image indicates that the background image integrally includes a plurality of second pixel points, and obtains a pixel value of each second pixel point; the background image represents other image presentation than the digital character display when the digital clock image is presented, for example, the background image may be entirely black, entirely white, or an image having other colors or shapes; after the background image and the second pixel value of each second pixel point of the background image are obtained in step S104, step S106 is required to be executed to fuse the background image with the character image, so as to obtain a complete digital clock image.
In step S106, the scheme fuses the background image with the plurality of character images determined in step S100 according to the transparency and the first pixel value of each first pixel point of each character image obtained in step S102 and the second pixel value of each second pixel point of the background image obtained in step S104, so as to obtain the target digital clock image.
In the digital clock display method, the transparency and the first pixel value of each first pixel point of the required character image are further obtained through obtaining the plurality of character images and the background image of the digital clock image to be generated, the second pixel value of each second pixel point of the background image is further obtained, the background image and the plurality of character images are fused according to the transparency and the first pixel value of each first pixel point of the character image and the second pixel value of each second pixel point of the background image, the digital clock image is obtained, the background image and the character image are fused according to the transparency of the character image when fused, the brightness of the fusion part of the character image and the background image is further combined better, fusion of the character image and the background image is more natural and smooth, and the problem that when the brightness of the corresponding pixel point in the digital clock image and the background image is fused in the existing fusion mode, the digital clock image has poor display effect after fusion is poor and the flatness is solved.
In an alternative implementation of this embodiment, the transparency and the first pixel value of each first pixel point of each character image described above may be stored in advance, and based on this, the manner in which step S102 obtains the transparency and the first pixel value of each first pixel point of each character image may be specifically as follows, as shown in fig. 2:
step S1020: and acquiring the transparency of each first pixel point and the index value associated with the first pixel value.
Step S1021: searching the transparency and the first pixel value of each first pixel point associated with each prestored index value according to the transparency and the index value associated with the first pixel value of each first pixel point.
In the above steps, the index value associated with the transparency and the first pixel value of each pixel point may be established in advance, and then the transparency and the first pixel value of the stored corresponding pixel point may be found out through the index value.
In an alternative implementation of this embodiment, it has been described that the transparency and the first pixel value of each first pixel point in the character image may be found by the index value, and before the implementation of step S100, the transparency and the first pixel value may be associated with the index value in advance, and the transparency and the first pixel value of each first pixel point in the character image are obtained by processing the original pixel value of the character image, as shown in fig. 3, which specifically includes the following steps:
Step S90: an original pixel value of each first pixel point of each character image in the digital clock image is obtained.
Step S91: and clustering all the first pixel points of the plurality of character images into vectors with preset numbers, and obtaining a second pixel value corresponding to each vector and an index value associated with each vector.
Step S92: and determining a target index value associated with the second pixel value corresponding to each first pixel point according to the original pixel value of each first pixel point and the second pixel value corresponding to each vector.
Step S93: and determining the transparency corresponding to each first pixel point and the first pixel value according to the second pixel value corresponding to each first pixel point.
Step S94: and associating and storing the transparency corresponding to each first pixel point and the first pixel value with the corresponding index value.
In step S90, it has been said that the device may store a series of character images, and then the pixel value of each pixel (first pixel) in the series of character images may be obtained, for example, the 0-9 character images have different colors, and then the pixel values are different, and after the original pixel value of each first pixel in each character image in the digital clock image is obtained, step S91 may be performed.
In step S91, the method clusters all the first pixels of the plurality of character images, specifically, a vector quantization algorithm is used to cluster the first pixels into a preset number of vectors, and a second pixel value corresponding to each vector is obtained, where each vector includes a plurality of pixels belonging to the same class, and the pixel values of the plurality of pixels belonging to the same class are the same and equal to the second pixel value corresponding to the vector, and in addition, an index value may be set for each vector according to the number of clustered vectors. For example, if the scheme is clustered into 256 vectors, and further can be clustered into 512, 1024, 2048 vectors, etc. according to the requirements or display effects in practical applications, the indexes of each vector can be set to be respectively corresponding to the index values of 0-255, and the second pixel values RGB corresponding to the vector with the index value of 0 are respectively assumed to be 0, 0 and 0, so that the second pixel values of the plurality of first pixel points belonging to the vector with the index value of 0 can be respectively 0, 0 and 0.
After the clustering is performed to obtain a plurality of vectors and the second pixel value and index value corresponding to each vector, step S92 may be performed, in which step S92, the scheme determines the vector to which each first pixel belongs, that is, the category to which each first pixel belongs, and further obtains the second pixel value and index value corresponding to each pixel, which may be specifically determined by the following steps as shown in fig. 4:
Step S920: and calculating the distance from each first pixel point to each vector according to the original pixel value of each first pixel point and the second pixel value corresponding to each vector, and correlating the vector nearest to the first pixel point and the index value correlated with the vector with the first pixel point.
In step S920, the method sequentially calculates the distance from each first pixel point to each vector in the character image, specifically, calculates the distance from each pixel point to each vector by the original pixel value of each first pixel point and the second pixel value corresponding to each vector, where specific calculation modes may be: distance = (red component of first pixel point-red component of vector) 2+ (green component of first pixel point-green component of vector) 2+ (blue component of first pixel point-blue component of vector) according to the foregoing example, assuming that the obtained vector is 256, 256 distances are calculated for each first pixel point, 256 distance values obtained for each first pixel point are compared, the second pixel value corresponding to the vector with the smallest distance is selected as the second pixel value of the first pixel point, and the index value associated with the vector with the smallest distance is selected as the index value of the first pixel point.
After the step of determining the second pixel value and the associated index value corresponding to each first pixel point is performed, step S93 may be performed, in which step S93, the method may determine the transparency corresponding to each first pixel point and the first pixel value according to the second pixel value corresponding to each first pixel point, where the specific process of determining the transparency corresponding to the first pixel point and the first pixel value may include the following steps:
step S930: and determining the maximum channel value of the three color channel values of the second pixel value corresponding to each first pixel point as the transparency corresponding to the first pixel point.
Step S931: and bringing the transparency corresponding to each first pixel point and the second pixel value corresponding to each first pixel point into a preset updating formula to calculate and obtain the first pixel value corresponding to each first pixel point.
In step S930, the second pixel value corresponding to each first pixel point includes three color channel values, i.e., a red component, a green component and a blue component, and the maximum channel value of the three color channel values is selected to be determined as the transparency corresponding to the first pixel point, for example, when the red component, the green component and the blue component of the second pixel value of a certain first pixel point are respectively 60, 80 and 100, then 100 is taken as the transparency of the first pixel point, and step S931 is performed on the basis of the selected transparency.
In step S931, the present solution updates the pixel value of each first pixel according to the transparency of each first pixel and the second pixel value corresponding to each first pixel determined in step S930, so as to obtain the first pixel value of each first pixel, and specifically, the present solution may bring the transparency corresponding to each first pixel and the second pixel value corresponding to each first pixel into a preset update formula, where the preset update formula is: first pixel value=second pixel value/transparency 255, and the transparency and second pixel value of each pixel point are brought into the update formula to obtain the first pixel value corresponding to each pixel point, so that step S94 can be further executed.
In step S94, the transparency and the first pixel value corresponding to each first pixel point are associated with the associated index value thereof and then stored, where, specifically, because the number of the pixels included in the character image is relatively large, the transparency and the first pixel value of each first pixel point of each character image may be stored in a register of the device, then the associated index value is stored in the memory, and when step S1020 and step S1021 are executed, the index value in the memory is read, and then the transparency and the first pixel value corresponding to the index value are searched in the register, so that the transparency and the first pixel value of each pixel point with relatively large data size are configured and stored in the register, and only the corresponding index value is stored in the memory, thereby reducing the memory storage space and saving the hardware resources.
In an alternative implementation of this embodiment, the background image may include a text area and a background area, where the text area represents a position where the character image is presented, each second pixel point in the text area overlaps with a corresponding first pixel point of the corresponding character image, and the background area represents an area where the character image is not presented and the background original image is presented, and on this basis, as shown in fig. 6, step S106 may specifically include the following steps:
step S1060: and respectively inputting the second pixel value of each second pixel point in the text region and the transparency and the first pixel value of the overlapped first pixel point in the corresponding character image of each second pixel point into a preset fusion formula to calculate and obtain the output pixel value of each second pixel point in the text region.
Step S1061: and generating a digital clock image according to the output pixel value of each second pixel point in the text region and the pixel value of each second pixel point in the background region.
In step S1060, the present scheme inputs the second pixel value of each second pixel in the text region and the transparency and the first pixel value of the first pixel overlapped in the character image corresponding to each second pixel into a preset fusion formula respectively, so as to calculate an output pixel value of each second pixel in the text region, where the preset fusion formula may be:
