IMAGE SENSOR, CONTROL METHOD THEREOF, AND ELECTRONIC APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18356373 titled 'IMAGE SENSOR, CONTROL METHOD THEREOF, AND ELECTRONIC APPARATUS

Simplified Explanation

The abstract describes an image sensor that includes sample-and-hold circuits, converters, a switch, and output circuits. The sample-and-hold circuits sample and hold signals from different pixels. The converters convert the held signals into currents corresponding to their potentials. The switch connects/disconnects the converters. The output circuits either add and output the converted currents or directly output them, depending on the switch's state.

  • The image sensor includes sample-and-hold circuits to capture signals from multiple pixels.
  • Converters are used to convert the held signals into currents that represent their potentials.
  • A switch is present to connect or disconnect the converters.
  • The output circuits either add and output the converted currents or directly output them, based on the switch's state.

Potential applications of this technology:

  • Digital cameras and smartphones: The image sensor can be used in digital cameras and smartphones to capture high-quality images.
  • Surveillance systems: The image sensor can be utilized in surveillance cameras for monitoring and recording purposes.
  • Medical imaging: This technology can be applied in medical devices such as X-ray machines and ultrasound scanners to capture and process medical images.

Problems solved by this technology:

  • Improved image quality: The use of sample-and-hold circuits and converters helps in capturing and converting signals accurately, resulting in better image quality.
  • Signal processing efficiency: The image sensor simplifies the process of converting signals into currents, making it more efficient and reliable.

Benefits of this technology:

  • Higher resolution: The image sensor allows for the capture of signals from multiple pixels, enabling higher resolution images.
  • Enhanced image accuracy: The converters ensure that the signals are accurately converted into currents, leading to more precise image representation.
  • Energy efficiency: The switch allows for the selective use of converters, reducing power consumption when not required.
