Abstract: Wireless control systems for cameras, and operational methods thereof are provided. The system includes a control device and a camera. The camera wirelessly receives a control signal from the control device. The camera captures a plurality of images via an image capture unit, and temporarily stores the images. A processing unit of the camera locates a specific image among the images according to the signal. In some embodiments, the specific image is located among the images according to the time after the time that the control signal is received and an image transmission delay, or according to identification embedded in the control signal.

Abstract: A combination apparatus and an operating method thereof are provided. The combination apparatus includes a first device, a second device and a connecting mechanism. The first device includes a first display unit and a first image capturing unit, wherein a picture is captured by the first image capture unit and converted into an image signal for the first display unit to display. The second device includes a second display unit with resolution different from that of the first display unit and is capable of wirelessly controlling the first device. The connecting mechanism is configured to detachably fasten the first device and the second device. The operating method of the combination apparatus includes utilizing the first device and/or the second device to capture a picture; and utilizing the first display unit and/or the second display unit to display the picture.
