The invention provides an image updating method and device, electronic equipment and a storage medium, and the method comprises the steps: receiving an image updating instruction sent by a remote control end after a first image is displayed, wherein the image updating instruction comprises position information of a target local area and serial number information of a corresponding target image, and the first image comprises at least one preset local area; extracting a corresponding target image from a local image library according to the number information; according to the position information, replacing a local image of a corresponding target local area in the first image with the target image to form a second image; and displaying the second image. Therefore, a remote control end does not need to directly send the whole new image data to the display screen, only the position information of the target local area and the serial number information of the corresponding target image need to be sent, the amount of data transmitted between the remote control end and the display screen can be effectively reduced, the transmission time is greatly shortened, and the timeliness of image updating is improved.

    本发明提供了一种图像更新方法、装置、电子设备及存储介质,通过当显示第一图像后,接收远端控制端发送的图像更新指令;所述图像更新指令包含目标局部区域的位置信息和对应的目标图像的编号信息;所述第一图像包含至少一个预设的局部区域;根据所述编号信息在本地的图像库中提取对应的目标图像;根据所述位置信息,用所述目标图像替换所述第一图像中对应的目标局部区域的局部图像,形成第二图像;对所述第二图像进行显示;从而无需由远端控制端直接把整个新图像数据发送到显示屏,而只需发送目标局部区域的位置信息和对应的目标图像的编号信息,可有效减小远端控制端与显示屏之间传送的数据量,大大减少传输时间,从而提高图像更新的及时性。
