IMAGING APPARATUS HAVING MEMORY INCLUDING VOLTAGE HOLDING CIRCUITS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18056956 titled 'IMAGING APPARATUS HAVING MEMORY INCLUDING VOLTAGE HOLDING CIRCUITS
Simplified Explanation
The patent application describes an imaging apparatus that includes a pixel and a memory. The pixel has a photoelectric conversion circuit and a charge/voltage conversion circuit. The memory is arranged to correspond to the pixel and includes multiple voltage holding circuits.
- The pixel in the imaging apparatus has a photoelectric conversion circuit that converts light into electrical charge and a charge/voltage conversion circuit that converts the charge into a voltage signal.
- The memory in the imaging apparatus is designed to match the pixel on a one-on-one basis and consists of several voltage holding circuits.
- Each voltage holding circuit in the memory is responsible for holding a voltage signal output from the pixel.
- The voltage holding circuits in the memory are connected in parallel.
- The voltage signals held in the different accumulation periods in the pixel are averaged to obtain an averaged voltage signal.
Potential applications of this technology:
- Digital cameras and video cameras
- Medical imaging devices
- Surveillance systems
- Machine vision systems
Problems solved by this technology:
- Improved image quality by averaging voltage signals from different accumulation periods
- Reduction of noise and artifacts in images
- Enhanced dynamic range and sensitivity in imaging
Benefits of this technology:
- Higher quality and more accurate images
- Improved performance in low-light conditions
- Increased flexibility in image processing and manipulation
- Enhanced overall imaging capabilities
Original Abstract Submitted
An imaging apparatus includes a pixel and a memory. The pixel includes a photoelectric conversion circuit and a charge/voltage conversion circuit. The memory is arranged so as to correspond to the pixel on a one-on-one basis and includes a plurality of voltage holding circuits each configured to hold a voltage signal output from the pixel. The voltage holding circuits hold respective voltage signals in different accumulation periods in the pixel and the voltage holding circuits are connected in parallel. The voltage signals in the different accumulation periods are averaged into an averaged voltage signal.
