Abstract:
Disclosed are a multi image reproducing apparatus and a multi image reproducing method. The multi image reproducing apparatus includes an image processor to process image data corresponding to a plurality of image contents and to output the image data by or in correspondence to the image contents, an image composition and output part or outputer to compose image frames of the image data input from the image processor and to output a composed mosaic split image frame, and a controller to receive operation information on the image composition and output part from the image composition and output part, to calculate optimal input time information of the image frames input from the image processor to the image composition and output part based on the received operation information, and to provide the calculated optimal input time information to the image processor.
Abstract:
Provided is an electronic device capable of checking whether a sub unit is connected to a main controller. The electronic device includes a main controller including a pulse width modulation (PWM) port, and at least one sub unit configured to receive a PWM signal from the main controller and to operate according to the PWM signal. The main controller checks whether the at least one sub unit is connected to the main controller via the PWM port.
