Abstract: Provided is a method of evaluating performance of a bio-sensor. The method may include obtaining an input bio-image by using the bio-sensor that is to be evaluated; obtaining a sample database including information of M reference bio-images, where M is a natural number; and calculating a quality score of the input bio-image based on the input bio-image and the information in the sample database. The quality score may provide an objective and quantitative score for evaluating a bio-image.

Abstract: Provided are a method of recognizing a fingerprint and a device including the same. The method of recognizing a fingerprint includes obtaining a fingerprint image from a fingerprint sensor, determining whether a pixel in the fingerprint image is defective based on a dispersion value of the pixel with respect to time, in response to determining that the pixel is defective, generating an interpolated pixel value of the pixel by performing interpolation on a first pixel value of the pixel based on a second pixel value of another pixel different from the pixel, and correcting the fingerprint image based on the interpolated pixel value.

Abstract: A touch screen device includes a touch pad including driving lines and sensing lines intersecting the driving lines, a driver configured to apply a driving signal to the driving lines, a signal output collector configured to receive a touch signal from the sensing lines, and a controller configured to control the driver and the signal output collector. The controller is further configured to control the driver to perform primary scanning to sequentially apply the driving signal to first driving lines disposed at predetermined intervals, among the driving lines, determine a scanning region, based on a first driving line where a touch is sensed among the first driving lines to which the driving signal is applied, and control the driver to perform secondary scanning to sequentially apply the driving signal to second driving lines included in the determined scanning region, among the driving lines.

Abstract: A method of manufacturing an organic-inorganic composite thin film may include: forming a thin film from a paste that includes an inorganic powder and an organic compound binder by using a screen printing process; and/or performing a pressing process and a heating process with respect to the thin film. The heating process may be performed at a glass transition temperature of the organic compound binder or in a temperature range higher than the glass transition temperature of the organic compound binder. An X-ray detector configured to detect X-rays irradiated from an outside of the X-ray detector may include: a photoconductive material layer in which electron-hole pairs are formed due to absorption of the X-rays. The photoconductive material layer may be formed of an organic-inorganic composite thin film that includes an inorganic powder and an organic compound binder.
