A method for determining the synchronization code under a standard mobile imaging architecture is provided. This method is essentially to solve any possible error occurring as transferring the images among the mobile devices. If any error is occurred to the transferred bit stream, it will cause fault in the image data. Consequently, the present invention provides an approach to compare every input data with iterative comparison operation, so as to obtain the position of synchronization codes under SMIA. Therefore, the correct synchronization code will solve the possible error translation.
