A detection device includes an image capture element, a control signal generator, and a processor. The image capture element is used for capturing an optical signal, and outputting an image signal. The control signal generator is used for generating a control signal. The processor selectively converts the image signal into an object feature or an image feature in response to the control signal. Such a detection device can appropriately convert an operation mode, so as to have both efficacies of reducing the amount of transferred data and processing complex image data.

A remote controller for controlling a display device includes a first image sensor, a processing unit and an activation mechanism. The first image sensor is for sensing an object and forming a digital image. The processing unit is coupled to the first image sensor for calculating image variations of the object on the digital image, correspondingly controlling the display device according to the image variations and deactivating the first image sensor after the remote controller is idle for a predetermined period of time. The activation mechanism is coupled to the first image sensor for re-activating the deactivated first image sensor.

A control device for an image display includes at least two reference points, a modulation unit and a remote controller. The modulation unit modulates the light of a predetermined spectrum generated by the reference points with a brightness variation cycle. The modulation unit controls the reference points to emit the light with a first brightness within a first period of the brightness variation cycle and to emit the light with a second brightness within a second period of the brightness variation cycle, wherein the first brightness and the second brightness are not zero gray level. The remote controller captures the light of the predetermined spectrum with a sampling cycle and demodulates an image variation of the reference points with respect to the remote controller. The present invention further provides a control method for an image display.

A cursor control device includes an image sensor, at least one button, a processing unit, a selection unit and a transmitter. The image sensor captures a plurality of image frames. The at least one button outputs a trigger signal while being pressed. The processing unit calculates a displacement according to the image frames and outputs a control signal according to the trigger signal. The selection unit selects one of at least two different cursor lock periods. The transmitter outputs the control signal and the displacement, wherein the processing unit controls the transmitter to output zero displacement within the cursor lock period selected after receiving the trigger signal. The present disclosure further provides a cursor control system.
