SIGNAL PROCESSING METHOD AND DEVICES, AND DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17638123 titled 'SIGNAL PROCESSING METHOD AND DEVICES, AND DISPLAY APPARATUS
Simplified Explanation
The patent application describes a method for frame synchronization in a digital system using pixel clock signals. Here are the key points:
- The method involves obtaining a first frame synchronization signal, where the period between a trailing edge of a first pulse and a leading edge of the next first pulse corresponds to a specific number of pulses of a first pixel clock signal.
- A synchronization calibration signal is generated, where the triggering edge of the second pulse is delayed compared to the trailing edge of the first pulse.
- A second frame synchronization signal is generated, where the period between the triggering edge of the second pulse and the leading edge of a third pulse corresponds to a specific time period.
- If the ratio of the frequency of the second pixel clock signal to the frequency of the first pixel clock signal falls within a certain threshold range, the second time period corresponds to a specific number of pulses of the second pixel clock signal.
- The specific number of pulses of the second pixel clock signal is determined by multiplying the specific number of pulses of the first pixel clock signal by the ratio of the two clock frequencies.
Potential applications of this technology:
- Digital video processing systems
- Image sensors and cameras
- Display devices and monitors
Problems solved by this technology:
- Ensures accurate frame synchronization in digital systems
- Allows for synchronization between different pixel clock signals with varying frequencies
Benefits of this technology:
- Simplifies the frame synchronization process
- Provides flexibility in synchronizing different clock signals
- Improves the overall performance and reliability of digital systems.
Original Abstract Submitted
A method includes: obtaining a first frame synchronization signal, period between a trailing edge of a first pulse and a leading edge of a next first pulse being first time period corresponding to a first integer number of pulses of a first pixel clock signal; generating a synchronization calibration signal, a triggering edge of the second pulse being delayed compared to a trailing edge of a first pulse; generating a second frame synchronization signal, period between a triggering edge of the second pulse and a leading edge of a third pulse being second time period. When ratio of frequency of the second pixel clock signal to frequency of the first pixel clock signal is within threshold range, the second time period corresponds to a second integer number of pulses of the second pixel clock signal. The second integer is integer value of product of the first integer and ratio.
