Abstract: A device and a method for searching an image with partial dynamic time matching using a binary section dividing algorithm are provided to reduce an error occurring in a process for extracting a Fourier coefficient, reduce an image search time through image classification, and increase search correctness by using the binary section division algorithm reducing the section for extracting the Fourier coefficient according to complexity of a curve. A user terminal(101) receives a query image from a user. An image processing module(103) extracts an image distance curve from the query image. A image classification module(107) classifies the image according to the number of partial curves from the image distance curve. A partial dynamic time matching module(113) restores the image distance curve from a Fourier coefficient set of the image included in the same group as classification information of the query image classified by the image classification module and matches the image distance curve of the query image with the restored image distance curve. An image database(111) stores the Fourier coefficient set included in the same group as the classification information of the query image. An image storing module(109) extracts the Fourier coefficient set of the query image classified by the image classification module.
