Description

[0001] This application is a divisional application filed with the Chinese Patent Office on February 12, 2014, with application number 2014100493422, entitled "Image Processing Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of image processing technology, and in particular to an image processing method and apparatus. Background Technology

[0003] Watermarking is an image overlay technique that adds information to an image without destroying its basic information. When sharing images on the internet, users often want to add richer information to the original image for effective emotional expression, and watermarking technology can add this information to the original image through overlay or fusion.

[0004] Traditional image processing methods typically add fixed signatures or current timestamps to images automatically as watermarks before uploading, which is a rather simplistic approach. When users want to add information related to the image content, they have to manually open a separate image processing tool, which is especially cumbersome when using mobile devices. Summary of the Invention

[0005] Therefore, it is necessary to provide an image processing method and apparatus that can simplify operation in response to the above-mentioned technical problems.

[0006] An image processing method, the method comprising:

[0007] Receive instructions to add a watermark;

[0008] Obtain regional information;

[0009] Obtain the default dialect text information corresponding to the aforementioned regional information;

[0010] The default dialect text information is overlaid on the original image as a watermark.

[0011] Receive the save command and generate the overlaid watermark image.

[0012] An image processing apparatus, the apparatus comprising:

[0013] The instruction receiving module is used to receive instructions on adding watermarks;

[0014] The first acquisition module is used to acquire geographic information;

[0015] The second acquisition module is used to acquire the default dialect text information corresponding to the regional information;

[0016] The overlay module is used to overlay the default dialect text information onto the original image as a watermark.

[0017] The image generation module is used to receive save commands and generate overlaid watermark images.

[0018] The aforementioned image processing method and apparatus, upon receiving a watermarking instruction, acquires regional information and corresponding default dialect text information, then overlays the default dialect text information as a watermark onto the original image, ultimately generating a watermarked image. This method and apparatus can automatically overlay default dialect text corresponding to the user's regional information onto the original image, eliminating the need for specialized image processing tools, greatly simplifying the operation and improving ease of use.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Unless otherwise specifically and clearly described in the context, the elements and components in the present invention can exist in a single form or in a multiple form, and the present invention does not limit this. Although the steps in the present invention are arranged with reference numerals, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It can be understood that the term "and / or" used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0027] As Figure 1 shown, in one embodiment, a picture processing method is provided. This method is illustrated by being applied to various terminals, including but not limited to various desktop computers, laptop computers, personal digital assistants, tablet computers, smart phones, e-book readers, MP3 (Moving Picture Experts Group Audio Layer III) or MP4 (Moving Picture Experts Group Audio Layer IV) players, etc. The method includes:

[0028] Step 102, receiving an instruction to add a watermark.

[0029] Step 104, obtaining geographical information.

[0030] The geographical information can be geographical information selected and input by the user, or the geographical location of the terminal obtained after positioning the terminal.

[0031] Step 106, obtaining default dialect text information corresponding to the geographical information.

[0032] In this embodiment, the geographical information and the corresponding default dialect text information are pre-stored, and the geographical information and the default dialect text information can be in a one-to-one or one-to-many relationship. For example, when the geographical information is "Shanghai", the corresponding default dialect is "Nong Hao", etc. According to the corresponding relationship between the pre-stored geographical information and the default dialect text information, the default dialect text information corresponding to the geographical information obtained in Step 104 is obtained. When there are multiple pieces of obtained default dialect text information, they can be displayed for the user to select.

[0033] Step 108, superimposing the default dialect text information on the original picture in the form of a watermark.

[0034] Step 110, receiving a save instruction and generating a watermarked picture after superimposition.

[0035] "Watermark" refers to overlaying a picture or text on an original picture so that the original picture has information similar to a label. Specifically, a new layer can be added to the original picture, and the default dialect text information can be added to this new layer. After receiving a save instruction, the new layer with the default dialect text information is merged with the original layer to generate a watermarked picture. It is also possible to, after receiving a save instruction, embed the default dialect text information as pixels into the original picture and then perform merging to generate a watermarked picture.

[0036] Preferably, multiple watermark templates can also be pre-stored. These watermark templates can contain preset pictures and define the format for placing text. After obtaining the default dialect text information corresponding to the regional information, the default dialect text information can be added to the preset position of the watermark template, and then the watermark template with the added default dialect text information is overlaid on the original picture. When receiving a save instruction, a superimposed watermarked picture is generated.

[0037] In this embodiment, it is possible to automatically overlay the default dialect text information corresponding to the user's regional information on the original picture without the user using a dedicated image processing tool, greatly simplifying the operation.

[0038] In one embodiment, step 104 includes: obtaining the regional information input by the user; or positioning the terminal to obtain the geographical location of the terminal, and determining the regional information where the user is located based on the geographical location of the terminal.

[0039] Further, in one embodiment, step 106 includes: reading the corresponding relationship between the pre-stored regional information and the default dialect text information; and obtaining the default dialect text information corresponding to the regional information input by the user or the regional information where the user is located according to this corresponding relationship.

[0040] In this embodiment, the regional information and the corresponding dialect text information are stored as a basic unit in advance. For example, if the region is "Shanghai", the corresponding dialect text is "Nong Hao", and this dialect text is the default dialect text corresponding to this regional information. When receiving an instruction to add a watermark, an interface can be displayed, and this interface includes a list of regions. The user can select a region through this interface. After obtaining the region selected by the user, the default dialect text information corresponding to the region selected by the user can be further obtained. If there are multiple default dialect text information, the user's selection is further received, and the default dialect text information selected by the user is overlaid on the original picture in the form of a watermark.

[0041] Specifically, the obtained geographical location of the terminal can be its latitude and longitude, the latitude and longitude of the base station it is located at, or its IP address. Furthermore, the user's geographical location can be determined based on the terminal's location. For example, the user's city can be determined based on the terminal's latitude and longitude or IP address. Since the geographical information and corresponding default dialect text information are pre-stored, after obtaining the user's geographical information, the corresponding default dialect text information can be found. When there are multiple default dialect text information corresponding to the user's geographical information, they can all be displayed for the user to select the default dialect text information to be overlaid on the original image.

[0042] Since it can display all default dialect text information corresponding to the region, allowing users to select the default dialect text information they want to overlay on the original image, and can also directly obtain the user's region and overlay the default dialect text information corresponding to the user's region onto the original image, the operation is further simplified.

[0043] like Figure 2 As shown, in another embodiment, an image processing method includes:

[0044] Step 202: Receive the instruction to add a watermark.

[0045] Step 204: Obtain regional information;

[0046] Step 206: Obtain the default dialect text information corresponding to the regional information.

[0047] Step 208: Overlay the default dialect text information onto the original image as a watermark.

[0048] Step 210: Receive instructions to edit the default dialect text information.

[0049] Step 212: Obtain the input custom dialect text information.

[0050] Step 214: Overlay the input custom dialect text information onto the original image as a watermark.

[0051] Step 216: Receive the save command and generate the superimposed watermark image.

[0052] In this embodiment, after receiving an instruction to edit the default dialect text information, an editing input box containing the default dialect text information can be generated on the original image. The default dialect text information that was originally in the editing input box can be deleted through the editing input box, and the user's custom dialect text information can be received through the editing input box.

[0053] Please refer to Figure 3 As shown, the original image is displayed on the terminal, with default dialect text information superimposed on it as a watermark. The user can tap the default dialect text information 302 on the original image, generating an edit input box 304. The default dialect text information 302 can be selected within the edit input box 304, allowing the user to easily delete it. Furthermore, the user can input custom dialect text information through the edit input box 304. When the user taps a location outside the edit input box 304, the input custom dialect text information is superimposed on the original image as a watermark. The user taps the save button to generate a watermarked image.

[0054] Since custom dialect text information can be directly edited on the original image, any dialect text can be overlaid on the original image as a watermark, further simplifying the operation.

[0055] In one embodiment, before receiving the save instruction and generating the overlaid watermark image, the method may further include: overlaying geographic information and / or the current time onto the original image as a watermark.

[0056] In this embodiment, when geographic information is obtained, it can be overlaid onto the original image, so that the generated watermark image includes the user-selected region or the user's current region. Furthermore, the generated watermark image can also include the current time, allowing the image generation time to be viewed from the watermark image.

[0057] Furthermore, after generating the watermarked image, it can be saved locally on the device or uploaded directly to a social network.

[0058] like Figure 4 As shown, an image processing apparatus is also provided, the apparatus comprising:

[0059] The instruction receiving module 402 is used to receive instructions to add a watermark.

[0060] The first acquisition module 404 is used to acquire regional information.

[0061] The second acquisition module 406 is used to acquire the default dialect text information corresponding to the regional information.

[0062] The overlay module 408 is used to overlay default dialect text information onto the original image as a watermark.

[0063] Image generation module 410 is used to receive save instructions and generate an overlaid watermark image.

[0064] The regional information can be the regional information selected and input by the user, or the geographical location of the terminal obtained after positioning the terminal. In this embodiment, the regional information and the corresponding default dialect text information are pre-stored, and the regional information and the default dialect text information can be in a one-to-one or one-to-many relationship.

[0065] Specifically, the picture generation module 410 can be used to add a new layer to the original picture, add the default dialect text information to the new layer, and after receiving the save instruction, fuse the new layer with the original layer added with the default dialect text information to generate a watermark picture. The picture generation module 410 can also be used to, after receiving the save instruction, embed the default dialect text information as pixels into the original picture, and then fuse to generate a watermark picture. In addition, multiple watermark templates can be pre-stored, and these watermark templates can include preset pictures and define the format for placing text. After the second acquisition module 406 acquires the default dialect text information corresponding to the regional information, the superimposition module 408 can superimpose the default dialect text information at the preset position of the watermark template, and then superimpose the watermark template with the default dialect text information superimposed on the original picture.

[0066] In one embodiment, the first acquisition module 404 is used to acquire the regional information input by the user; or is used to position the terminal to acquire the geographical location of the terminal, and determine the regional information where the user is located according to the geographical location of the terminal.

[0067] Further, in one embodiment, the second acquisition module 406 is used to read the corresponding relationship between the pre-stored regional information and the default dialect text information; and acquire the default dialect text information corresponding to the regional information input by the user or the regional information where the user is located according to the corresponding relationship.

[0068] In this embodiment, the regional information and the corresponding dialect text information are pre-stored as a basic unit. For example, if the region is "Shanghai", the corresponding dialect text is "Nong Hao", and this dialect text is the default dialect text corresponding to the regional information.

[0069] Specifically, the geographical location of the terminal acquired by the first acquisition module 404 can be the latitude and longitude of the terminal, the latitude and longitude of the base station where the terminal is located, or the IP address of the terminal, etc. Furthermore, the first acquisition module 404 can be used to determine the user's geographical location based on the terminal's geographical location. For example, the user's city can be determined based on the terminal's latitude and longitude or IP address. Since the geographical information and corresponding default dialect text information are pre-stored, after obtaining the user's geographical information, the second acquisition module 406 can find the default dialect text information corresponding to the user's geographical information. When there are multiple default dialect text information corresponding to the user's geographical information, they can be displayed together for the user to select the default dialect text information to be overlaid on the original image.

[0070] In one embodiment, such as Figure 5 As shown, the image processing apparatus may further include:

[0071] The editing module 412 is used to receive instructions to edit the default dialect text information and to obtain the input custom dialect text information.

[0072] In this embodiment, the overlay module 408 is also used to overlay the input custom dialect text information onto the original image.

[0073] The editing module 412 can be used to generate an editing input box containing the default dialect on the original image after receiving an instruction to edit the default dialect. The default dialect that was originally in the editing input box can be deleted through the editing input box, and the user's custom dialect can be received through the editing input box.

[0074] In one embodiment, the overlay module 408 is also used to overlay geographical information and / or the current time onto the original image as a watermark.

[0075] Furthermore, after generating the watermarked image, the image generation module 410 can be used to save the watermarked image locally on the terminal, or directly upload the watermarked image to a social network.
