Abstract: A method of synchronization adjustment is applied to an optical detecting device, so as to synchronize an exposure timing sequence of an image detector with a light emitting timing sequence of an indicating light source. The method includes acquiring a continued image set, analyzing intensity of each image of the continued image set, and adjusting the exposure timing sequence according to duty cycle of the image detector and intensity ratio of at least two images. An exposure frequency of the image detector is greater than a flickering frequency of the indicating light source.

Abstract: There is provided an encoding and decoding method and an information recognition device using the same. A code block includes a center coding region and a peripheral coding region arranged around the center coding region. The encoding and decoding method uses the feature of at least one microdot included in the center coding region as codes. The encoding and decoding method uses the feature of at least one microdot included in the peripheral coding region as codes. The encoding and decoding method uses the relative feature between the center coding region and the peripheral coding region as codes. The information recognition device compares the read feature with pre-stored features to decode information such as position codes, object codes, parameter codes and control codes.
