If the screen aspect ratio of the display screen of the projection device is: the ratio of the vertical dimension of the screen to the horizontal dimension of the screen, the aspect ratio of the display frame may be: the ratio of the picture length to the picture width.
In the embodiment of the present disclosure, the aspect ratio of the display screen may be calculated according to the screen width and the screen length of the display screen. In this way, after the screen aspect ratio of the display screen of the screen projection device is obtained, the screen aspect ratio and the picture aspect ratio can be compared to obtain a comparison result, and whether to convert the picture length and/or the picture width of the display picture is determined according to the comparison result. For example, if the comparison result indicates that the aspect ratio of the display picture is not equal to the aspect ratio of the screen, the picture length and/or the picture width of the display picture are/is adjusted according to the obtained conversion parameter until the aspect ratio of the display picture is equal to the aspect ratio of the screen.
For another example, if the width of the displayed picture is 8 centimeters (cm), the length of the picture is 6cm, the aspect ratio of the picture is 4:3, the lateral dimension of the screen of the display screen of the projection device is 32cm, the longitudinal dimension of the screen is 18cm, and the aspect ratio of the screen is 16:9, since the aspect ratio of the picture is not equal to the aspect ratio of the screen, the length of the picture and/or the width of the picture of the displayed picture can be adjusted.
In some embodiments, if the screen width needs to be adjusted, the conversion parameter for converting the displayed screen is determined to be 4/3, for example, the screen width may be adjusted to 4/3 of the original screen width, that is, the screen width is adjusted from 8cm to 32/3 (cm).
In other embodiments, if the frame length needs to be adjusted, the conversion parameter for converting the display frame may be determined to be 3/4, for example, the frame length may be adjusted to 3/4 of the original frame length, that is, the frame length is adjusted from 6cm to 4.5cm, so that the aspect ratio of the display frame is equal to the screen aspect ratio.
In other embodiments, the frame length and the frame width may be adjusted simultaneously, so that the aspect ratio of the displayed frame is equal to the screen aspect ratio.
In the embodiment of the present disclosure, after the screen length and/or the screen width of the display screen are adjusted, the screen aspect ratio of the adjusted display screen can be equal to the screen aspect ratio. Therefore, after the display picture on the mobile terminal is projected to the screen projection device in an equal proportion, the display picture can be matched with the display screen of the screen projection device, and full-screen display of the display picture on the screen projection device can be achieved.
In some embodiments, the method further comprises:
and displaying the display picture on a display screen of the mobile terminal according to the target size.
