Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a picture storing method according to an exemplary embodiment of the present disclosure, where the picture storing method provided in the embodiment of the present disclosure may be applied to an intelligent terminal such as a smart phone, a smart tablet, a wearable device, a personal palm assistant, and a personal computer, and the present disclosure does not limit a specific type of an electronic device. For convenience of description, the present disclosure will be described below by taking an example in which the picture storage method is applied to an intelligent terminal.

As shown in fig. 1, the picture storing method includes the following steps.

In step S101, pixel data of a picture is acquired when picture storage is performed.

The pictures in the disclosure can be obtained by shooting by the intelligent terminal or by downloading through network acquisition, and when the pictures are stored, the pictures are stored in the local storage space of the terminal, so that the user can conveniently perform subsequent editing and use. It will be appreciated that when picture pixels are large, the space required for picture storage is correspondingly large.

A pixel, i.e. the smallest unit in a picture represented by a numerical sequence, is the smallest element that is inseparable in a single picture. In a picture, the clear position and assigned color value of a pixel determine the effect that the picture exhibits. When the picture is stored, the picture to be stored is divided into pixels relative to the whole storage of a single picture, and the picture is stored by taking the pixels as units by acquiring the pixel data of the picture. It is to be understood that, in order to reduce the picture storage space, the storage may not be repeated for pixels having the same color value. For example, the colors of the background regions in the picture are the same, i.e. the color values of the background regions are the same. Only one color value may be saved for a pixel that appears repeatedly.

In step S102, pixel data of the picture is saved to store the picture.

When the picture is stored, the picture is divided into pixels, and the corresponding picture is stored by storing pixel data.

According to the method provided by the disclosure, when the picture is stored, the picture is split into the pixels, the pixel data of the picture is stored, the storage mode of the picture is changed, and the occupation of the storage space of the equipment is reduced.

In one embodiment, the pixel data for a picture is saved in a pixel bank.

One or more pixel banks may be created, and the pixel data of the picture may be stored in the pixel banks. The pixel library can be stored in a local storage space of the terminal, and can also be uploaded to a server and stored in a cloud space, so that the occupation of the storage space is further saved.

In one embodiment, the pixel data is stored in a pixel bank corresponding to the time and/or place of capture based on the time and/or place of capture of the picture.

The pixel library may be created according to the shooting time and/or shooting location of the picture. The method comprises the steps of establishing a corresponding pixel library according to shooting time and/or shooting places, storing pixel data of pictures shot at the same shooting time and/or shooting places in the pixel library corresponding to the shooting time and/or shooting places, wherein the pictures shot at the same shooting time and/or shooting places can comprise more same or similar pixels, the same pixels are not repeatedly stored, the storage space is saved, and the speed of reading and/or presenting the pictures when the pictures are subsequently read can be improved.

Fig. 2 is a flowchart illustrating a picture storing method according to another exemplary embodiment of the present disclosure. The pixel data includes a pixel value and a pixel coordinate, and the pixel value may be an RGB value including a color of the pixel point, or an RGB and transparency value of the pixel point. And the pixel coordinates are used for representing the position of the pixel in the picture. The pixel coordinates may be determined by a coordinate system, which may be a picture coordinate system, a camera coordinate system, a world coordinate system, etc. The method comprises the steps of obtaining pixel data of a picture, namely obtaining a pixel value and a pixel coordinate of each pixel point of the picture, and displaying the picture according to the pixel value and the pixel coordinate when the picture is browsed.

As shown in fig. 2, the step of storing the pixel data of the picture in the pixel bank includes the following steps.

In step S201, the current pixel value is looked up in the pixel bank.

When the picture is stored, the picture is divided into pixels, and the corresponding picture is stored by storing pixel data. In order to save storage space, pixels with the same pixel value in different pictures or in the same picture are stored in the pixel library only once, namely, are not stored repeatedly. It will be appreciated that for pixel data in a pixel bank, the same pixel value may correspond to one pixel coordinate or to a plurality of pixel coordinates. The current pixel value is looked up in the pixel bank, and it is determined whether a pixel having the same value as the current pixel already exists in the pixel bank. For the pixels with the same pixel value, when two pieces of pixel data with the same pixel value are stored, only the different pixel coordinates representing the positions of the pixels in the picture need to be stored.

In an embodiment of the present disclosure, when storing a picture, a code is assigned to pixel data to distinguish different pixel data. When the picture is stored again, the distributed codes are analyzed, the current pixel values are inquired in the pixel library, and the pixel values in the pixel data of the distributed codes are compared.

In step S202, when the pixel value of the pixel point is not found in the pixel library, the pixel value and the pixel coordinate are stored in the pixel library.

When the pixel value is not inquired in the pixel library, the pixel value does not exist in the pixel library, and the pixel data, namely the pixel value and the pixel coordinate of the pixel point are stored in the pixel library so as to be convenient for subsequent pixel data reading and use.

In step S203, when the pixel value of the pixel point is found in the pixel library, the pixel coordinate of the pixel point is added to the pixel data corresponding to the found pixel value.

When the pixel value is inquired in the pixel base, the pixel value is indicated to exist in the pixel base, at this time, only the pixel coordinate used for representing the pixel position in the pixel data needs to be stored in the pixel base, namely the pixel coordinate of the pixel point is added in the pixel data corresponding to the inquired pixel value.

Fig. 3 is a flowchart illustrating a picture storing method according to another exemplary embodiment of the present disclosure. The pixel coordinates have picture identifiers, which are used to distinguish different pictures, as shown in fig. 3, the picture storage method includes the following steps.

In step S301, pixel data of a picture is acquired when picture storage is performed.

When the pictures are stored, picture identifiers are distributed to the pictures so as to distinguish pixel coordinates of different pictures according to the picture identifiers.

In step S302, the pixel data of the picture is saved to store the picture.

In step S303, in response to detecting an operation to view a picture, pixel data of the picture is read according to the picture identification.

In one embodiment, the pictures are saved in the gallery in the form of preview pictures, and the preview pictures of the pictures are stored in low pixels, so that the occupation of storage space is reduced.

And when a user clicks a preview of the picture in the gallery to view the picture, determining the picture according to the picture identification, and reading pixel data corresponding to the picture. For example, the pixel values and the pixel coordinates of all pixels corresponding to the picture may be acquired in a pixel library to present the picture, so that the user is ensured to view the picture with high-quality pixels, and the user experience is improved.

In step S304, a picture is presented according to the pixel data in the running memory.

The operating Memory of the terminal is a space for storing or temporarily storing a program when the terminal operates, and can temporarily store data for exchanging cache data with the CPU, and generally refers to a Random Access Memory (RAM).

When a user clicks the picture to check the picture, the picture is presented in the running memory according to the pixel value and the pixel coordinate of the picture, and the occupation of the picture on the storage space of the terminal can be avoided.

Fig. 4 is a flowchart illustrating a picture storing method according to another exemplary embodiment of the present disclosure. As shown in fig. 4, the picture storing method includes the following steps.

In step S401, pixel data of a picture is acquired at the time of picture storage.

In step S402, pixel data of a picture is saved to store the picture.

In step S403, in response to detection of an operation to view a picture, pixel data of the picture is read.

In step S404, a picture is displayed according to the pixel data in the running memory.

In step S405, in response to detecting that the operation of viewing the picture is ended, the pixel data of the presentation picture is cleared in the running memory.

And when the user clicks the picture to check the picture, displaying the picture according to the pixel value and the pixel coordinate of the picture in the running memory. When the user finishes the reading of the current picture and does not edit or save the current picture to the local album before closing the read picture, pixel data of the picture is cleared in the running memory, and the picture is still saved in the gallery in the form of a preview.

In the process of opening, reading and quitting reading after reading, the storage space of the terminal is not occupied, the space occupation of the running memory is emptied, and the influence on the performance of the terminal caused by the fact that the running memory is occupied and the storage space is large when the large-pixel picture is read is avoided.

The same pixel value may correspond to one pixel coordinate or to a plurality of pixel coordinates in the pixel data in the pixel library. When a user performs a picture deletion operation, the pixel value of the picture may belong to other undeleted pictures, and the pixel data of the picture is deleted, which may cause data loss of other pictures. When the picture is deleted, the pixel coordinate corresponding to the picture is deleted in the pixel data according to the picture identification, so that the occupation of the storage space can be reduced, and the influence on other pictures sharing the pixel value with the picture can be avoided.

In an embodiment, the picture storage method further includes, after deleting the pixel coordinate corresponding to the picture in the pixel data, querying a pixel value corresponding to the pixel coordinate in the pixel data, and deleting the pixel data corresponding to the pixel value when the pixel value corresponding to the pixel coordinate does not have the corresponding pixel coordinate.

When a user deletes a picture, the pixel coordinate corresponding to the picture is deleted from the pixel data, and the pixel data can also be inquired about whether other corresponding pixel coordinates exist, that is, whether the pixel coordinate is shared with other pictures.

And when the pixel value corresponding to the pixel coordinate does not have the corresponding pixel coordinate, namely the pixel value is not shared with other pictures, deleting the pixel data corresponding to the pixel value in the pixel library.

In an embodiment of the present disclosure, when a user clicks a picture to perform a picture viewing operation, a pixel value and a pixel coordinate of the picture are obtained, the picture is presented in an operating memory according to the pixel value and the pixel coordinate of the picture, and when the user performs a sending operation on the picture in a process of viewing the picture, the picture is sent according to the pixel value and the pixel coordinate of the picture. The quality of the original pixels of the picture is guaranteed.

In an embodiment of the present disclosure, when a user clicks a picture to perform a picture viewing operation, a pixel value and a pixel coordinate of the picture are obtained, the picture is presented according to the pixel value and the pixel coordinate of the picture in an operating memory, the picture is edited in a process of the user viewing, and the edited picture is stored according to pixel data of the picture when the edited picture is stored.
