Abstract: Disclosed is a phase difference detection pixel using a microlens, which detects a phase difference without the loss of an input signal by modifying the shape of a microlens, which collects light incident into a photodiode, such that the light passes through only in a specific direction. In the phase difference detection pixel using a microlens, a signal reduction problem, which is a disadvantage of the existing phase difference detection pixel, is solved and a phase difference detection function is achieved in all areas of an image sensor. The phase difference detection pixel using a microlens is variously applied for distance measurement between objects or three-dimensional image capturing.

Abstract: A contents downloading system and a method thereof. According to the system, when a media device is connected to a detachable user terminal device, a device identifier is transmitted to the user terminal device from the media device. The user terminal device then transmits the device identifier to a server device that provides contents corresponding to the device identifier, and the server device transmits the contents selected based on the device identifier and an environment to download configured by a user. Since the media device is automatically connected to a specific website providing every kind of contents necessary for each media device based on the device identifier of the media device, the user can download the contents more conveniently without driving a web browser or selecting contents to be downloaded.

Abstract: A system and method for improving the use of a recording medium of an AV (audio-video) system. The system and method perform the operations of calculating storage capacity remaining in the recording medium, recording to the recording medium, and displaying the storage capacity remaining in the recording medium when the storage capacity remaining in the recording medium is less than a predetermined level. Accordingly, a user can be informed that the storage capacity remaining in the recording medium is less than a predetermined level when the recording is performed in the AV system, and the user can delete files already stored in the recording medium to enable the recording to continuously operate without interruption due to lack of storage space.
