The signal processing device according to an embodiment of the present disclosure includes: a frame buffer to store an input image and output an output image, an output synchronization signal calculator to calculate an output synchronization signal based on an input synchronization signal and a size or a position of the output image in comparison with the input image, and an output synchronization signal output interface to output a variable output synchronization signal of which a start timing changes based on a signal from the output synchronization signal calculator, wherein a difference between a start timing of the input synchronization signal and a start timing of the output synchronization signal changes based on the size of the output image. Accordingly, a delay time may be reduced in response to the output image having a size different from a size of the input image being output.

A method and system for synchronization of image data is provided. From a plurality of image-capture devices, image data including a plurality of image sequences is received. Each image sequence corresponds to one of the plurality of image-capture devices. A set of sensor data is further received from the plurality of image-capture devices. Each sensor data comprises at least one of an Inertial Measurement Unit (IMU) data and audio data. Based on the received set of sensor data, a match is determined between a first set of image frames of a first image sequence and a second set of image frames of a second image sequence. An offset is computed between the first set of image frames and the second set of image frames, based on the match and the first image sequence is synchronized with the second image sequence based on the computed offset.
