摘要

The present invention relates to a product search system using a sketch, a user device, a service providing device, a service method for same, and a recording medium storing a computer program thereof. The product search system extracts sketch images corresponding to a user′s strokes generates by touching a sketch area, outputs the extracted sketch images to a search result output area as a search result, and exposes the sketch images with high similarity to overlap the sketch area while applying a weighted value to the paid sketch images to provide the paid sketch images frequently and highlight the paid sketch images when the paid sketch images are overlapped and exposed. When a database is built in the service providing device to store the candidate sketch images provided to the user device, a user uploading the images can determine sketch exposure costs. The service providing device can provide the uploaded images as the sketch images in a differentiated manner according to the sketch exposure costs. The images which a user paid higher costs for can be provided for the user device more frequently and exposed to enhance the advertisement effect.
