20100327925 | CALIBRATING MULTIPLYING-DELAY-LOCKED-LOOPS (MDLLS) - Devices and methods for varying individual periods or cycle times of upconverted clock signals within a corresponding reference clock cycle are disclosed. In some embodiments, these varying cycle times may improve signal synchronization between the upconverted clock and the reference clock. In different embodiments, different types of counters and counting circuits keep track of the number of elapsed upconverted clock cycles in order to determine the specific upconverted clock cycles with longer cycle times. In some embodiments, a signal may be sent to a delay line to change the amount of delay between upconverted clock pulses, thereby increasing or decreasing a specific upconverted clock cycle time or period. In some embodiments the specific upconverted clock cycle(s) changed in each reference clock cycle may vary, which may further improve reconciliation between the upconverted clock cycles and the corresponding reference clock cycle. | 12-30-2010 |
20130258143 | IMPULSE NOISE REMOVAL DESIGN FOR BAYER PATTERN IMAGE SENSOR - A system and method provide for an adaptive median filter with edge protection and four line buffers to remove the impulse noise for a Bayer pattern image. The system and method separates the Bayer pattern image data into different channels by color and applies the adaptive median filter to remove the impulse noise on each channel. The adaptive median filter has five threshold values that may be modified to achieve different light condition response based on the detected noise level of the image. Thus, proper threshold values with better brightness response to the input pixels may be applied and impulse noise may be suppressed effectively, while preserving image details. | 10-03-2013 |
