20210335326 | METHOD AND APPARATUS FOR IMPROVING VISIBILITY OF CLUSTER DESIGN ELEMENTS BASED ON DRIVER'S VIEW - Embodiments relate to an apparatus for improving visibility of cluster design elements based on a driver's view, including an eye position detection unit to detect an eye position of the driver from a face image captured through a camera in a vehicle, a visible area determination unit to determine a visible area and an invisible area in a cluster based on the detected eye position, a position of the cluster in the vehicle and a position of a steering wheel, a display information detection unit to detect a position and shape of display information displayed on the cluster, and a display information design conversion unit to convert a position or shape of display information overlapping in the invisible area among the display information. | 2021-10-28 |
20210335327 | A METHOD FOR PROCESSING IMAGE DATA WITH REDUCED TRANSMISSION BANDWIDTH FOR DISPLAY - A method for processing image data with reduced transmission bandwidth is provided. The method includes receiving a first set of data for image in a first resolution and receiving a center coordinate. The method further includes determining a high-definition region including an area and a boundary centered on the center coordinate. Additionally, the method includes rendering the first set of data based on the center coordinate and the area of the high-definition region to obtain a first subset of data. Furthermore, the method includes rendering a set of data compressed from the first set of data to obtain a second subset of data beyond the boundary. Moreover, the method includes transmitting a second set of image data to the display panel combining the first subset of data for display image in the first resolution and the second subset of data to display image in the second resolution. | 2021-10-28 |
20210335328 | SIGNAL PROCESSING DEVICE AND IMAGE DISPLAY APPARATUS INCLUDING THE SAME - The present disclosure relates to a signal processing device and an image display apparatus including the same. The signal processing device includes a synchronizer configured to perform Fourier transform based on the received baseband signal, and an equalizer configured to extract a pilot signal from a signal from the synchronizer, to calculate a channel transfer function value of the extracted pilot signal, and to selectively perform time interpolation based on the calculated channel transfer function value. Thus, time interpolation is selectively performed based on the channel. | 2021-10-28 |
20210335329 | Musical Instrument Arm Support - A musical instrument support system provides support to a musician's elbow when the musician's arm is in a raised position, thus alleviating fatigue and strain on the musician's shoulder, neck, back and arms. The support system includes a harness worn on the musician's torso, a rib plate supported by the harness that is worn along the musician's torso, an elbow support that receives the musician's elbow, and a swivel joint that joins the elbow support to the rib plate and permits the elbow plate to rotate and angulate about a vertical axis and move laterally from the rib plate in all directions within a horizontal plane. | 2021-10-28 |
