If the user uses one of the images included in the IQS as a query for CBIR-based search for the similar images, the service providing server determines the image as the initial query of CBIR-RF. The service providing server generates a list of the most similar result images by calculating a distance between the query image and all image of a database, and induces the user to determine suitability by presenting the images in turn. If the user purchases the presented image, the service providing server stores details to the database(S111).

A magnetic ink character recognition apparatus of an automatic bill receiving machine is composed of a magnetic recognition head(32') installed at the side of a carrying path(21) to recognize and obtain magnetic ink character information of a bill(p) by contacting a lower head surface to the bill moving through the carrying path and a press unit(34') for improving the recognition efficiency by pressing the magnetic recognition head to the bill. The press unit comprises a vertical guide member(34a') having a vertical guide groove(34a-1') closely receiving the upper end of the magnetic recognition head and moving the magnetic recognition head with vertically guiding the magnetic recognition head, and an extension coil spring(34b') moving the magnetic recognition head down by applying elastic force extended from the upper side to the upside of the magnetic recognition head inserted into the vertical guide groove.

Abstract: An OLED and a driving method thereof are provided to maintain high display quality by improving the discharge characteristics of capacitors and the hysteresis characteristics of driving transistors. An OLED(Organic Light-Emitting Diode) includes first and second transistors(T1,T2), a capacitor(C), and a third transistor(T3). The first transistor outputs a data voltage having a first polarity in response to an n-th scan signal. The second transistor supplies current to the OLED in response to the data voltage from the first transistor. The capacitor stores the data voltage from the first transistor. The third transistor supplies a precharge voltage having a second polarity to the second transistor and capacitor in response to an (n-1)-th scan signal.
