PROJECTION IMAGE DISPLAY APPARATUS
The projection image display apparatus includes a display element that emits image light generated by modulating light from a light source based, a pixel-shifter that shifts a pixel of a projected image by changing an optical path of the image light, a resampling circuit, a motion-interpolation image processing circuit, and a pixel-shift controller. The resampling circuit generates a plurality of sub-frame image signals having a resolution of the display element, by resampling an image signal having a resolution of the projected image. The motion-interpolation image processing circuit provides a motion-interpolation image process to the sub-frame image signals. The pixel-shift controller receives the sub-frame image signals having undergone the motion-interpolation image process. The pixel-shift controller drives the display element and the pixel shifter at a given timing based on the sub-frame image having undergone the motion-interpolation image process, and then displays the projected image, which involves pixel-shift, on a screen.
VIDEO BUFFERING AND FRAME RATE DOUBLING DEVICE AND METHOD
A frame buffer having a size of one video frame of a video stream is provided. The video stream has a source frame rate. Image data units of the video stream are written consecutively to the frame buffer in accordance with a circular buffering scheme and in real-time response to the video stream. Image data units are read from the frame buffer in accordance with the circular buffering scheme with a frame rate that is twice the source frame rate so as to generate a target video stream having a frame rate which is twice the source frame rate. The frame buffer can be used in a real-time video system, for example in a vehicle.
Display apparatus and driving method thereof
A display apparatus and a driving method thereof capable of assuring reliability in frame inversion driving and improving cinema video image quality are provided. To accomplish this, a display apparatus of the embodiment replaces at least one of a plurality of frame images obtained by doubling the frame rate, with a different image before display. Specifically, the display apparatus replaces at least one of the double-speed converted plural frame images with a high-frequency emphasized image and at least one with a low-frequency component image, and displays the frame images. Furthermore, the display apparatus replaces an image at the border between cinema images with a different image before displaying.
Signal processing device and video display device comprising same
Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate a source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.

METHODS AND CAMERA MONITOR SYSTEMS SUPPORTING MULTIPLE LOW-VOLTAGE DIFFERENTIAL SIGNALING STANDARDS
A CMS includes a camera mounted to a commercial vehicle. The camera is configured to provide a video feed of an external environment of the commercial vehicle. The CMS includes an electronic control unit (ECU) that includes processing circuitry operatively connected to memory. The processing circuitry is configured to receive the video feed from the camera over a wired interface, and the video feed is serialized. The processing circuitry is configured to deserialize the video feed according to a first low-voltage differential signaling (LVDS) standard based on the video feed being serialized according to the first LVDS standard, and deserialize the video feed according to a second LVDS standard based on the video feed being serialized according to the second LVDS standard. A method for a camera monitor system (CMS) is also disclosed.
