In this embodiment, described first sensor 120 is a depth transducer (as degree of depth video camera), described second transducer 140 is an image sensor (as RGB video camera), and the described first resolution that described depth transducer has is less than the described second resolution that described image sensor has.For example, described first resolution (i.e. the resolution of depth map) is QVGA, 320*240.Described second resolution (resolution of the picture namely captured) is VGA, 640*480.But the present invention is not limited to this, such as both resolution can be other different multiples, and even both disproportionate relations of resolution also within the scope of the invention.
Please refer to Fig. 1 and Fig. 2, wherein, Fig. 2 is the time diagram of the first data crossfire 220 and the second data crossfire 240.Described synchronizer 160 is electrically connected at described first sensor 120 and described second transducer 140, for controlling the sequential of described first data crossfire 220 and described second data crossfire 240, described first data crossfire 220 and described second data crossfire 240 is made to have synchronous vertical synchronizing signal (Vertical sync, VSYNC).As shown in Figure 2, the first data crossfire 220 has multiple data line signal 222, and each data line signal 222 comprises the amount of information of each data line, and one first picture frame (or claiming frame frame) data that described multiple data line composition first sensor 120 captures.Therefore, described multiple data line signal 222 comprises the data line signal 222 (3) of data line signal the 222 (2), the 3rd row of data line signal the 222 (1), the 2nd row of the 1st row ... to the data line signal 222 (240) of the 240th row.Similarly, the second data crossfire 240 has multiple data line signal 244, and each data line signal 244 comprises the amount of information of each data line, and described multiple data line forms one second drawing frame data that the second transducer 140 captures.Therefore, described multiple data line signal 244 comprises the data line signal 244 (3) of data line signal the 244 (2), the 3rd row of data line signal the 244 (1), the 2nd row of the 1st row ... to the data line signal 244 (480) of the 480th row.
In this embodiment, described synchronizer 160 controls described first sensor 120, and to export moment of the data line signal 222 (1) of the 1st row identical with the moment that described second transducer 140 exports the data line signal 244 (1) of the 1st row, as shown in Figure 2.That is, first sensor 120 and the second transducer 140 export the timing synchronization of described first picture frame and the second picture frame, have reached and have had synchronous vertical synchronizing signal.
Referring again to Fig. 1, described colligator 180 in conjunction with described first data crossfire 220 and described second data crossfire 240 to form a data output tape sorting 260.Because first sensor 120 has synchronous vertical synchronizing signal with the second transducer 140, make in a picture frame time (frame time), what described colligator 180 received is all the data that first sensor 120 and the second transducer 140 capture in same time.The first sensor 120 therefore with different resolution can reach synchronous with the second transducer 140, thus solves existing degree of depth video camera and the unmatched problem of RGB video camera.
