As the camera enabled mobile device distribution and the amount of images that users store are increased, there is an increase in the necessity of the image retrieval system which allows an efficient retrieval and management of images. The color-based retrieval system brings out a specific feature, we call as color-feature, by splitting each partition of the space depending on its color. Also, the system determines the similarity of images by calculating the differences from the color-feature from different image's spaces. As the size and quantity of images which are supported by mobile devices increase, the image retrieval system processed using existing software that uses the CPU becomes a limitation in real-time processing. Therefore, we have proposed and implemented a hardware architecture by accomplishing real-time color-based image retrieval system in our study. Compared to the previous method using mobile CPU, experimental results show that the proposed hardware architecture reduces 99% processing time of image conversion and 99% processing time of image retrieval.
