Method and apparatus for determining presence of user's hand tremor or intentional motion

摘要

A method is provided for determining presence of a user's hand tremor or intentional motion during recognition of an image through photographing. Image sample blocks of a previous frame are detected by using an edge detecting method. A block distance between the detected image sample block of the previous frame and an estimated image sample block of a current frame is calculated. The calculated block distance is compared with a first threshold. The calculated block distance is compared with a second threshold when the calculated block distance is less than the first threshold.
