IMAGE SENSOR FOR MEASURING DISTANCE AND CAMERA MODULE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17945688 titled 'IMAGE SENSOR FOR MEASURING DISTANCE AND CAMERA MODULE INCLUDING THE SAME
Simplified Explanation
The patent application describes an image sensor and camera system that utilizes a demodulation clock generation circuit, demodulation phase selection circuit, delay circuit, and phase mixer to generate demodulation signals with varying phases. The phases of the demodulation signals are changed based on a random number and an address that changes for each packet.
- The image sensor includes a demodulation clock generation circuit that generates four demodulation clock signals with different phases.
- A demodulation phase selection circuit generates pre-demodulation signals based on the demodulation clock signals and a random number that changes for each packet.
- A delay circuit generates delay signals by delaying the pre-demodulation signals by multiple delay phases.
- A phase mixer generates demodulation signals with changed phases based on an address that changes for each packet.
- The demodulation signals have a phase difference of 90° from each other.
Potential applications of this technology:
- Digital cameras and video cameras
- Surveillance systems
- Medical imaging devices
- Automotive cameras
- Industrial inspection systems
Problems solved by this technology:
- Improved image quality and resolution
- Reduced noise and interference in image capture
- Enhanced signal processing capabilities
- Increased flexibility in adjusting image sensor parameters
Benefits of this technology:
- Higher quality and more accurate image capture
- Improved performance in low light conditions
- Enhanced image processing capabilities
- Increased versatility and adaptability in various applications
Original Abstract Submitted
An image sensor and a camera are provided. The image sensor includes: a demodulation clock generation circuit configured to generate first to fourth demodulation clock signals respectively having first to fourth phases; a demodulation phase selection circuit configured to generate first to fourth pre-demodulation signals based on the first to fourth demodulation clock signals and a random number that changes for each of a plurality of packets; a delay circuit configured to generate a first delay signals, second delay signals, third delay signals and fourth delay signals by delaying the first to fourth pre-demodulation signals by a plurality of delay phases; and a phase mixer configured to generate first to fourth demodulation signals of which phases are changed based on an address that changes for each of the plurality of packets. The first to fourth phases have a phase difference of 90° from each other.
