摘要： A system selects either a first scaler in a host computer or a second scaler in a display device, the first scaler having a predetermined output quality. The system instructs the display device to render a pattern; determines the output quality of the second scaler; and compares the quality of the second scaler with the predetermined output quality and selects the scaler with higher quality.

摘要： A system provides automatic mode detection and scaler control in a display device which is digitally coupled to a display controller. The display controller has a variable active horizontal resolution and a variable active vertical resolution, while the display device has a fixed display device horizonal resolution and a fixed display device vertical resolution. The system determines the variable active horizontal and the vertical resolutions of the display controller; and scales the output of the display controller to the fixed horizontal resolution and vertical resolution of the display device.

摘要： A system positions an image with a plurality of lines on a display device. The system determines the number of black lines required to vertically center the image in a frame of the display device as m+n; displays m black lines using a first horizontal sync period at the start of each frame, the first horizontal sync period being less than the horizontal sync period of the display device; displays each line of the image; and displays n black lines using the second horizontal sync period until the end of the frame.

摘要： A color correction filtering system filters color video data by compensating for non-linearities and color characteristics specific to a color monitor. Color video data is received by the system, for example through a web browser, and in an accelerated manner passed through a pre-calculated gamut-shifting array. The color correction filtering system gamma decompensates incoming color video data referenced to a non-linear color space through use of a linearization filter. The gamut-shifting array may contain pre-calculated compensation values stored in a plurality of look-up tables. A non-linearization filter is applied to the gamut-shifted color video data to produce color video data compensated for non-linearities specific to the color monitor.

摘要： A method of detecting touch events on a touch panel includes identifying sets of coordinate locations based on at least one signal from at least one sensor. The at least one signal is responsive to at least one touch event, and the coordinate locations represent matches with respect to template fingerprints. Consecutive ones of the sets of coordinate locations are compared based on a first distance threshold to form streams of spatially continuous coordinate locations that satisfy the first distance threshold. A touch event is identified corresponding to one of the streams of spatially continuous coordinate locations, the stream having a minimum number of spatially continuous coordinate locations.

摘要： A method for detecting a touch event on a touch panel comprises obtaining at least first and second signals from at least two sensors where the at least first and second signals are responsive to a touch event. A first amplitude magnitude associated with the first signal is calculated and a second amplitude magnitude associated with the second signal is calculated. A magnitude ratio is determined between the first and second amplitude magnitudes, and a touch location is identified based on the magnitude ratio.

摘要： A method of detecting a touch event on an acoustic fingerprint based touch system comprises digitizing at least two signals to form first and second sets of digitized signals. The at least two signals are received from at least two sensors on a touch panel. A frequency transform is performed upon the first and second sets of digitized signals to form first and second frequency transform data sets of frequency components. At least first and second live fingerprints are constructed wherein at least one of the first and second live fingerprints is based on the first and second frequency transform data sets. A touch location is identified based on the at least first and second live fingerprints.

摘要： A method for calibrating an Acoustic Pulse Recognition (APR) touchscreen comprises touching an APR touchscreen at N comparison touch points. N audio profiles are acquired, and each of the N audio profiles are associated with one of the N comparison touch points. A predetermined calibration file is selected based on the N audio profiles. The predetermined calibration file comprises audio profiles associated with coordinate locations on the touchscreen.
