In the embodiment of the present invention, the first electronic device further includes a collecting unit, and the collecting unit can collect an image of an environment where the first electronic device is located. Here, the acquisition unit is realized by a camera. The environment is photographed with a camera to capture an image of the environment.
Step 102: and identifying a display area of the second electronic equipment based on the image acquisition result.
In the embodiment of the invention, the first electronic device analyzes the image acquisition result to obtain the characteristic contour of the image, and specifically, the characteristic contour of the image can be distinguished according to the gray information of the image. And then, whether the characteristic contour is matched with the set standard contour is detected, and when the characteristic contour is matched with the set standard contour, the characteristic contour is indicated to contain an area which is not a display area of the second electronic equipment. Since the display area of the second electronic device is generally rectangular, the set standard outline is also rectangular, and of course, the standard outline may be set according to the actual display area of the second electronic device.
In the embodiment of the present invention, the second electronic device may be an electronic device such as a mobile phone and a tablet computer. The second electronic device has a display module capable of displaying a certain content. Specifically, the display module of the second electronic device may be a solid display screen or a virtual projection unit.
Step 103: and determining a projection display area which is matched with the display area of the second electronic equipment, and projecting and displaying the first content in the determined projection display area so as to display the second content in cooperation with the second electronic equipment.
In the embodiment of the invention, the projection display area is determined based on the projection parameters, namely the projection display area can be determined according to the projection parameters. To this end, based on the display area of the second electronic device, at least one of the following projection parameters adapted to the display area of the second electronic device is determined: the direction of the projected display; an area of the projected display region; the position of the display area is projected. The projected display area is determined.
In the embodiment of the invention, before the determined projection display area projects and displays the first content, the first electronic equipment and the second electronic equipment establish communication connection; dividing the second content into the first content and a third content based on the position relation between the projection display area and the display area of the second electronic equipment; and sending the third content to the second electronic equipment based on the communication connection, wherein the third content is used for being displayed in a display area of the second electronic equipment by the second electronic equipment.
