When the electronic photo frame is in a normal picture browsing state, the display control module 142 is configured to play a corresponding picture according to the user's operation. When the electronic photo frame is in the picture parameter adjustment state, the specific operation mode of the display control module 142 is: when the button 12 generates a skip operation control signal, the display control module 142 enters the next picture parameter of the current picture parameter. Adjustment, that is, skipping the adjustment of the current picture parameter, directly adjusting the next picture parameter; when the control signal generated by the button is the switching operation control signal, the different picture values of the current picture parameter and the corresponding picture display state thereof Switching between, wherein each switching operation control signal is generated, switching from the current parameter one parameter value and its corresponding picture display state to the current picture parameter another parameter value and its corresponding picture display state, therefore, more than 12 keys When the switching operation control signal is generated, the different parameter values of the current picture parameter and their corresponding picture display states are sequentially displayed, so that the user can select the parameter value. When the button 12 generates a selected operation control signal, the display control module 142 selects the parameter value corresponding to the current picture display state as the adjustment value of the current picture parameter, and performs the next picture based on the adjusted picture according to the adjusted value. Adjustment of parameters.

Each picture parameter is adjusted in sequence according to the above manner, and the state after the last picture parameter adjustment is the final adjustment result of the picture. For example, suppose the current picture parameter is the display angle, and its corresponding parameter values are rotated by 90°, rotated by 180°, rotated by 270°, and rotated by 0°. Angle of view The next picture parameter is the display brightness, which has five parameter values: normal, bright, very bright, dark, and very dark. When the skip operation control signal generated by the button 12 is received, the display control module 142 enters the parameter adjustment of the display brightness and displays a picture display state corresponding to the display brightness value. When the button 12 generates a switching operation control signal, the display control module 142 displays the picture state corresponding to the rotation of 90°, and when the switching operation control signal is generated again, the display control module 142 displays the picture display state corresponding to the rotation of 180°. . When the parameter value of the current picture parameter and the corresponding picture display state desired by the user appear, for example, the display state corresponding to the rotation of 90°, the user can generate the selected operation control signal by pressing the button 12, and the selected display angle value is rotated by 90° and correspondingly The picture shows the status and the brightness value adjustment is displayed by entering the next picture parameter based on the rotated 90° picture.

In the embodiment, when the time T of continuously pressing the button 12 is greater than a predetermined time T1, the processing unit 14 recognizes that the control signal generated by the button 12 is a skip operation control signal; when the button T is continuously pressed, the time T is less than or equal to When the predetermined time T1 is reached, the processing unit 14 recognizes that the control signal generated by the button 12 is a switching operation control signal; when the button 12 is double-clicked, the processing unit 14 recognizes that the operation control signal generated by the button 12 is the selected operation control signal. The predetermined time T1 is stored in the storage unit 13, and may be a preset value of the system, or may be defined by the user.

The electronic photo frame further provides a specific button, and the image parameter adjustment is entered by starting the specific button; the electronic photo frame can also provide a function table item, and the picture parameter adjustment is entered by executing the function table item.

2 is an embodiment of the present invention using the electronic photo frame of FIG. Flow chart of the method of parameter adjustment. The initial state of the process is that after the specific button or function entry is adjusted to enter the picture parameter, the reading module 141 reads the specific time value T1 and the picture parameter adjustment sequence table, and enters the picture parameter adjustment sequence table. The adjustment of the recorded first picture parameter (step S201).

The operation signal input by the user from the button 12 is received (step S202).

The display control module 142 compares the time T of pressing the button with the specific time T1 (step S203).

If T>T1, the display control module 142 enters the next picture parameter adjustment of the current picture parameter, that is, skips the adjustment of the current picture parameter, and directly adjusts the next picture parameter, and the flow goes to step S208.

If T<=T1, the display control module 142 adjusts the current picture parameter and displays the picture display state corresponding to the current picture parameter-parameter value, that is, each adjustment operation signal corresponds to the current picture parameter-parameter value and the parameter value corresponds to The picture display state is obtained (step S204).

Further, a new button signal is received (step S205).

The display control module 142 determines whether the newly received button signal is a double tap. If it is not double clicked, the flow returns to step S203 (step S206).

If the button 12 is double-clicked, the display control module 142 displays the control module 142 to select the parameter value corresponding to the currently displayed picture as the adjustment value of the current picture parameter, thereby completing the adjustment of the current picture parameter (step S207).

The display control module 142 determines whether the current picture parameter has the next picture parameter according to the picture parameter adjustment sequence table, and if there is no next picture parameter, ends the adjustment of the picture (step S208).

If there is a next picture parameter, the display control module 142 adjusts the next picture parameter of the current picture parameter based on the adjusted picture, and sets the next picture parameter as the current picture parameter, and the process goes to step S202 ( Step S209).

Specifically, if the button 12 is clicked and the next picture parameter exists, the display control module 142 enters the next picture parameter adjustment of the current picture parameter, that is, skips the adjustment of the current picture parameter, and directly adjusts the next picture parameter. And the next picture parameter is set as the current picture parameter, the process goes to step S202; if the button 12 is double-clicked and the next picture parameter exists, the display control module 142 selects the parameter value corresponding to the currently displayed picture as the adjustment of the current picture parameter. The value is adjusted according to the adjusted picture to enter the next picture parameter of the current picture parameter, and the next picture parameter is set as the current picture parameter, and the flow proceeds to step S202.

According to the picture parameter adjustment sequence table, the next picture parameter adjustment of the current picture parameter is entered (step S209).

Therefore, when the picture parameters are adjusted, different control signals are generated by the button 12, and the adjustment between the picture parameters can be switched. For example, if the adjustment state of the current picture parameter is: by pressing the time T<= the predetermined time T1 of the button 12, the display control module 142 displays the picture display state corresponding to the different parameter values of the current picture parameter. The adjustment of the current picture parameter requires only pressing the time T of the button 12 > the predetermined time T1, and then the adjustment of the current picture parameter is jumped to the next picture parameter adjustment.

In addition, in the process of adjusting the picture parameters, the display unit 15 also displays related information of the current picture parameters, including the name of the current picture parameter. It refers to the picture parameter and parameter value corresponding to the current picture state, and also displays the name of the next picture parameter, so that the user can proceed to the next step. For example, if the next picture parameter of the current picture parameter is the display angle, and the user does not need to adjust the display angle of the picture, then the user only needs to press the time 12 of the button 12 > predetermined time after completing the current picture parameter adjustment. T1, you can skip the display angle and directly enter the next picture parameter adjustment of the display angle.
