Optionally, in an implementation manner of the embodiment of the present application, the first object is an image, and as shown in fig. 2 in combination with fig. 1, the step 203 may be specifically implemented by the following steps 301 to 303.

In the embodiment of the present application, the storage format of the second object is the same as the storage format of the first object, that is, in the case that the first object is in the image format, the second object is in the image format.

Optionally, in this embodiment of the present application, the step 301 may be specifically implemented by the following steps 301a to 301 c.

Step 301a, the object encryption device sends a first display signal to the main control chip through the independent display chip.

In an embodiment of the present application, the first display signal is used to indicate image content of the second object that is subjected to image processing.

In the embodiment of the application, the object encryption device performs image processing on the first object through the independent display chip to obtain the second object, and if the object encryption device needs to display the second object, the object encryption device needs to send the first display signal to the main control chip through the independent display chip, so that the main control chip can forward the first display signal to the display unit through the MIPI to display the image content of the second object, which is subjected to the image processing.

It should be noted that, in the object encryption device according to the embodiment of the present application, the independent display chip is connected to the main control chip in a hardware structure, and the display unit is connected to the main control chip in a hardware structure through the MIPI.

And step 301b, the object encryption device sends a second display signal to the display unit through the main control chip.

In an embodiment of the present application, the second display signal is used for indicating image content of the second object.

Optionally, in this embodiment of the application, the second display signal includes content of the first display signal.

In the embodiment of the application, after the object encryption device receives the first display signal,

in step 301c, the object encryption apparatus displays the second object through the display unit.

In the embodiment of the application, after the object encryption device receives the second display signal sent by the main control chip, the second object is displayed through the display unit.

Illustratively, the object encryption device is a mobile phone, and the first object is an image. As shown in (a) of fig. 3, the mobile phone displays the image editing interface 10, and the first object 11 is displayed in the image editing interface 10, as shown in (b) of fig. 3, the user processes (i.e. adds the icon identifier 12) the first object 11 displayed in the image editing interface 10 through the mobile phone, so that the mobile phone displays the second object 13 in the image editing interface 10. It should be noted that the dashed boxes in (b) in fig. 3 are only for convenience of illustrating the first object 11, the image identifier 12 and the second object 13, and these dashed boxes may not be displayed in the image editing interface 10 in an actual implementation process.

Step 302, the object encryption apparatus receives a first input from a user.

In an embodiment of the present application, the first input is a frame selection input for a target image area in the second object.

Optionally, in this embodiment of the application, the first input may be a frame selection input performed by a user through sliding or dragging on a second object displayed by the object encryption device, so as to trigger the object encryption device to obtain the size of the area input by the user, and mark the area framed by the user.

Step 303, the object encryption device marks the target image area in the second object in response to the first input, and encrypts the target image area to obtain the target object.

Optionally, in this embodiment of the present application, the manner in which the object encryption apparatus marks the target image area in the second object may include at least one of the following: adding a solid frame in the target image area and changing the color of the target image area.

Exemplarily, in conjunction with (b) in fig. 3, as shown in fig. 4, the user selects the image identifier 12 in the image editing interface 10 through a frame selection input, so that the mobile phone displays a selection frame according to the input of the user, and marks the area corresponding to the image identifier 12 as the target image area.

In the embodiment of the application, under the condition that the first object is an image, a user can perform frame selection input on the second object displayed by the object encryption device, so that the object encryption device marks the frame-selected area of the user as a target image area, the flexibility of selecting the target image area is improved, and the diversity of object processing effects of the object encryption device is improved; the object encryption device can encrypt the target image area, so that the target image area is protected by encryption, and the copyright of the image after secondary creation can be effectively protected.

Optionally, in another implementation manner of the embodiment of the application, the first object is a video, and with reference to fig. 1, as shown in fig. 5, the step 203 may be specifically implemented by the following step 304.

And step 304, the object encryption device encrypts a target image area in at least one target video frame through the independent display chip to obtain a target object.

In an embodiment of the present application, the at least one target video frame is determined by any one of: a sensitive video frame in the second object, a video clip selected by the user in the second object.

It should be noted that the sensitive video frame can be understood as: video frames relating to user privacy information, such as video frames including a face portion of a user; or, a video frame with key information, i.e. a video frame matching preset key information, such as password information.

Optionally, in this embodiment of the present application, when performing encryption processing on at least one target video frame, the object encryption apparatus may select a different area in each of the at least one video frame to determine that the area needs to be encrypted.

Exemplarily, taking the first object as a video as an example, as shown in (a) in fig. 6, the mobile phone displays a video frame 15 in the video editing interface 14, and the user triggers the mobile phone to mark the image identifier 16 in the video frame 15 for encryption processing through a frame selection input; as shown in (b) in fig. 6, the mobile phone displays the video frame 17 in the video editing interface, and the user triggers the mobile phone to mark the image identifier 18 in the video frame 17 for encryption processing through a frame selection input. It should be noted that the dashed boxes in fig. 6 are only for convenience of illustrating the video frames 15 and 17, and these dashed boxes may not be displayed in the video editing interface 14 in the actual implementation process.

In the embodiment of the application, when the first object is a video, the object encryption device encrypts the target image area in at least one target video frame, so that the target video frame in the first object is protected by encryption, and the copyright of the video after secondary creation can be effectively protected.

Optionally, in this embodiment of the application, the step 203 may be specifically implemented by the following step 203 a.

Step 203a, the object encryption device performs inverse transformation processing on the pixel value of each pixel point in the target image area in at least one pixel channel through the independent display chip, so as to encrypt the target image area and obtain the target object.

In an embodiment of the present invention, the at least one pixel channel is a red pixel channel (R), a green pixel channel (G), and a blue pixel channel (B).

Optionally, in this embodiment of the application, the "object encryption apparatus performs inverse transformation processing on the pixel value of each pixel point in the target image region in at least one pixel channel through the independent display chip" in the step 203a may specifically be implemented through the following step 203a 1.

Step 203a1, if the pixel value of the target pixel point in the target pixel channel is within the target preset range, the object encryption device transforms the pixel value of the target pixel point in the target pixel channel into the target pixel value through the independent display chip.

In this embodiment, the target pixel value is a difference between a maximum critical value of a target preset range and a pixel value of a target pixel point in a target pixel channel.

In this embodiment, the target pixel point is any pixel point in the target image region, and the target pixel channel is any pixel channel in the at least one pixel channel. It can be understood that the object encryption device may determine a pixel value range of a pixel value of each pixel point in each pixel channel in the target image region, and then determine whether to transform the pixel value of the pixel point according to the pixel value range.

Optionally, in this embodiment of the application, if the pixel value of the target pixel point in the target pixel channel is not within the target preset range, the object encryption device will keep the pixel value of the target pixel point in the target pixel channel unchanged.

Optionally, in the embodiment of the present application, the target preset range may be 128 ≦ x ≦ 255, where the maximum threshold of the target preset range is 255.

It should be noted that, when the pixel value of the target pixel point in the target pixel channel is greater than or equal to 128, the object encryption device obtains the difference between the maximum critical value 255 of the target preset range and the pixel value x of the target pixel point in the target pixel channel, that is, the object encryption device obtains the value of 255-x as the target pixel value; when the pixel value of the target pixel point in the target pixel channel is less than 128, the object encryption device keeps the pixel value of the target pixel point in the target pixel channel unchanged.

For example, as shown in fig. 7, the image resolution of the target image area is M × N, and the mobile phone may obtain pixel values of M × N pixel points in the target image area. When the pixel value of any one pixel point a in the target image region is (11, 127, 200), the target pixel value corresponding to the pixel value of the pixel point a is (11, 127, 55).

In the embodiment of the application, after the object encryption device marks the target image area, the object encryption device obtains the image resolution of the target image area, and determines the number of the pixel points in the target image area, so that the object encryption device can obtain at least one pixel value of each pixel point in the target image area, and thus the object encryption device can encrypt the target image area more accurately by transforming partial pixel values of the target pixel points in the target pixel channel, and the accuracy of encryption processing of the object encryption device is improved.

The embodiment of the application provides an object encryption method, which is an object encryption device with a main control chip and an independent display chip, and can store the original content of a first object through the main control chip and perform image processing on the first object through the independent display chip to obtain a second object, so that the object encryption device performs encryption processing on a target image area through the independent display chip to obtain a target object. In the scheme, the object encryption device processes the first object through the independent display chip to obtain the second object, and encrypts the second object, so that when the object encryption device needs to display the second object, decryption processing corresponding to the encryption processing needs to be executed to increase steps required by the object encryption device to display the second object, thereby effectively protecting the copyright of the image or video after secondary creation.

Optionally, in this embodiment of the application, after the step 203, the object encryption method provided in this embodiment of the application further includes the following steps 401 to 404.

Step 401, in the case that it is detected that the key information input by the user matches the encryption key information of the second object, the object encryption apparatus performs decoding processing on the target object through the independent display chip.

In the embodiment of the application, a user can preset an encryption coding and decoding switch of the independent display chip, namely encryption key information of the second object, so that when other users need to check the second object, the key information needs to be input and is matched with the encryption key information of the second object.

Optionally, in this embodiment of the present application, the encryption key information may include at least one of the following: numeric passwords, alphabetic passwords, graphical passwords.

It can be understood that, in the case where the key information input by the user matches the encryption key of the second object, that is, the password input by the user is correct, the object encryption apparatus decodes the target object to display the target object after the decoding is successful, that is, the second object.

Step 402, the object encryption device sends a third display signal to the main control chip through the independent display chip.

In an embodiment of the present application, the third display signal is used to indicate the image content of the decoded target object.

And step 403, the object encryption device sends a third display signal to the display unit through the main control chip.

Step 404, the object encryption apparatus displays the decoded target object through the display unit.

In this embodiment, the decoded target object is a second object. It can be understood that, after the display unit receives the third display signal sent by the main control chip, that is, the object encryption device decodes the target object, the object encryption device displays the first object and the second object.

Alternatively, in the embodiment of the present application, as shown in (a) of fig. 8, when the first object is an image, the object encryption apparatus generates an original signal after saving an original image portion of the one image by the main control chip and generates an encrypted signal after making and saving a post-processing portion of the one image by the separate display chip, and when key information input by the user matches encryption key information of the second object, the object encryption apparatus transmits the original signal and the decoded signal to the display unit by MIPI to display the image. As shown in (b) of fig. 8, when the first object is a video, the specific processes of the object encryption method and the object decryption method of the object encryption device are similar to those of the first object which is an image, and are not repeated herein.

Optionally, in this embodiment of the application, the decoding process may be performed by the object encryption device reversely executing the encryption processing method provided in step 203a1, that is, the object encryption device obtains a target pixel value in a target pixel, and obtains a difference between a maximum critical value of a target preset range and the target pixel value, that is, obtains an original pixel value of the target pixel.

For example, in conjunction with (b) of fig. 2, as shown in fig. 9, if the key information input by the user matches the encryption key information of the second object, the mobile phone may display the second object 13 in the image display interface 19.

In the embodiment of the application, the object encryption device displays different objects according to the matching condition of the key information input by the user and the encryption key information of the second object, namely, the object encryption device displays the encrypted image or video under the condition that the key information is matched, so that the risk that the encrypted image or video is leaked when the key information is not matched is reduced.

Optionally, in this embodiment of the present application, after the step 203, the object encryption method provided in this embodiment of the present application further includes the following steps 501 to 503.

Step 501, under the condition that the key information input by the user is detected not to be matched with the encryption key information of the second object, the object encryption device sends a fourth display signal to the main control chip through the independent display chip.

In the embodiment of the present application, the fourth display signal is used to indicate the image content of the second object except for the target image area.

It is understood that in the case where the key information input by the user does not match the encryption key information of the second object, i.e., the password input by the user is wrong, the object encryption apparatus does not display the image content corresponding to the target image area, thereby protecting the copyright of the target image area.

In the embodiment of the present application, the image object of the second object except for the target image area may be understood as that, on the basis of the second object, the image content of the second object corresponding to the target image area is not displayed. For example, a mosaic is displayed in the target image area, or the image content of the corresponding first object is displayed in the target image area.

Step 502, the object encryption device sends a fifth display signal to the display unit through the main control chip.

In the embodiment of the present application, the fifth display signal is used to indicate the original content of the first object and the image content of the second object except for the target image area.

In addition, if the target image area is an image area of the second object that has been subjected to image processing, the image content of the second object other than the target image area may be an image area of the second object that has not been subjected to image processing.

In step 503, the object encryption apparatus displays the third object through the display unit.

In an embodiment of the present application, the third object includes at least one of: and objects except the target image area in the first object and the second object.

Optionally, in this embodiment of the application, when the third object is an object outside the target image area in the second object, the object encryption device may display a blank image in an area corresponding to the target image area, or add a mosaic to the image content of the target image area, so that the user cannot view the image content of the second object corresponding to the target image area.

Illustratively, referring to fig. 2 (b), as shown in fig. 10, if the key information input by the user does not match the encryption key information of the second object, the mobile phone cannot display the target image area (i.e., the icon identification 12) in the second object 13 in the image display interface 19, so as to display the first object 11 in the image display interface 19.

In the embodiment of the application, the object encryption device displays different objects according to the matching condition of the key information input by the user and the encryption key information of the second object, namely, the object encryption device does not display the encrypted image or video under the condition that the key information is not matched, so that the risk of the encrypted image or video being leaked is reduced.

It should be noted that, in the object encryption method provided in the embodiment of the present application, the execution subject may be an object encryption device, or an electronic device, or may also be a functional module or an entity in the electronic device. The embodiment of the present application takes an example of an electronic device executing an object encryption method, and describes an object encryption apparatus provided in the embodiment of the present application.

Fig. 11 shows a schematic diagram of a possible structure of an object encryption apparatus according to an embodiment of the present application. As shown in fig. 11, the object encryption device 70 may include: a storage module 71 and a processing module 72.

The storage module 71 is configured to store original content of a first object, where the first object is an image or a video.
