Methods are proposed for object positioning for an X-Y projected capacitive touch panel. In an embodiment, capacitance sensing under inphase excitation of traces is applied to set a base value when the capacitive touch panel is not touched and to obtain capacitances at intersections when the capacitive touch panel is touched, and the base value is compared with the measured capacitances to identify touch points. In other embodiments, X-Y projected sensing and all-point sensing are combined to reduce the amount of calculation and achieve the same positioning effect as an all-point capacitive touch panel.

A method is disclosed for producing and exhibiting high-quality three-dimensional (3-D) motion pictures. Stereoscopic images are placed side by side on a strip of motion picture film, such images having been anamorphically compressed to fit into the 70 mm or other film format used for presentation. These images are then reciprocally expanded to produce the aspect ratio of the original images as photographed. A single strip of motion picture film is used and images intended to be seen through the left or right eye of the viewer of such films are slightly different, to create the 3-D effect. To minimize the amount of light projected onto the screen, projection is accomplished by use of a projector capable of accomplishing pulldown between frames in five milliseconds of less and equipped with a single 0-bladed shutter at high frame rates, specifically 48 frames per second or higher. The method described here allows for screen sizes considerably larger than those currently in use for theatrical 3-D presentation. Viewers of films produced by this method can observe the images projected through polarized glasses or by other means known in the art. The 3-D effect can be withdrawn as desired by presenting identical images for the right and left eyes, thus delivering two-dimensional (2-D) presentation. Existing 3-D movies can be converted for exhibition according to the method described, with significant improvement in picture quality and smoother appearance of motion. In addition, films can be made to deliver 3-D effect for certain scenes or sequences within a motion picture presentation, with 2-D presentation for other scenes or sequences within the same motion picture.

In image-data recording processing performed when a video output conforms to the PAL system, a display-signal processing section receives image data having a frame rate of 30 Hz recorded in a memory, through a bus, converts the image data to image data having an NTSC frame rate of 29.97 Hz by a frame-rate conversion method in which thinning out is performed according to the ratio of frame rates, and outputs it to a display section and a codec-IC interface. The display-signal processing section also converts to image data having a PAL frame rate of 25 Hz, and outputs it to a video-output interface. In other words, image data is processed at a frame rate not related to the output, and then converted to image data having a frame rate suited for the output, and output. This invention can be used in digital cameras.

The trigger logic can be readily configured by a user operating an interface, which can also be used to configure the main inspection process, to trigger the vision system by tools such as presence-absence, edge finding, barcode finding, pattern matching, image thresholding, or any arbitrary combination of tools exposed by the vision system in the interface.

A method is provided to improve the frame-rate in color-flow ultrasound imaging using simultaneous spatially-distinct transmit beams with one or more frequency bands per transmit beam. Pulses of different center frequencies are used simultaneously in different (lateral and/or elevational) directions, thereby reducing the scanning time and improving the frame-rates. Optionally, a multi-modal pulse is used, and flow is estimated separately for the different frequencies. The flow estimates for these pulses are appropriately combined to improve low-velocity sensitivity and to reduce aliasing. A flow sample count with two or more different pulse repetition intervals can be used to further improve low-flow sensitivity and minimize aliasing.
