AN IMAGE SENSING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240040275 titled 'AN IMAGE SENSING SYSTEM

Simplified Explanation

The abstract describes an image sensing system that uses a rolling shutter image sensor, a lens system, a light generator, a timing module, and a processor.

  • The rolling shutter image sensor scans each image line sequentially, making the pixels sensitive to light for a predetermined exposure time and determining the intensity readout for each pixel.
  • The lens system projects at least two similar outgoing images of an object onto the image sensor, with the outgoing images offset from each other in the scanning direction. Each pixel of an outgoing image corresponds to a pixel or group of pixels of another outgoing image at the same position on the object.
  • The light generator generates at least two different colors of light with different wavelengths to illuminate the object. The timing module controls the light generator to sequentially generate these different colors of light during the scanning of a single frame.
  • The processor identifies matched pixels of different outgoing images corresponding to the same position on the object and resolves the color spectrum of the object based on the intensity readout of each matched pixel and the colors of light that the matched pixels were exposed to.

Potential applications of this technology:

  • 3D imaging: The system can be used to capture depth information by analyzing the offset between the outgoing images and resolving the color spectrum of the object.
  • Color analysis: By resolving the color spectrum of the object, the system can be used for color analysis in various fields such as art, fashion, and product design.
  • Object recognition: The system can help in identifying and distinguishing objects based on their color spectrum, which can be useful in applications like surveillance and robotics.

Problems solved by this technology:

  • Accurate color representation: By matching pixels from different outgoing images, the system can accurately determine the color spectrum of an object, even in challenging lighting conditions.
  • Depth perception: The offset between the outgoing images allows for the capture of depth information, enabling 3D imaging without the need for multiple cameras or complex depth sensors.

Benefits of this technology:

  • Improved image quality: The system provides accurate color representation and depth perception, resulting in high-quality images with enhanced visual information.
  • Simplified setup: By using a single rolling shutter image sensor and a lens system, the system eliminates the need for multiple cameras or complex depth sensors, making it easier to set up and use.
  • Versatility: The system can be applied to various imaging applications, including 3D imaging, color analysis, and object recognition, making it a versatile solution for different industries.


Original Abstract Submitted

according to an aspect, there is provided an image sensing system comprising: a rolling shutter image sensor comprising an array of pixels in a frame arranged into a plurality of image lines extending along a width direction, and distributed in a scanning direction which is perpendicular to the width direction, wherein the rolling shutter image sensor is configured to scan the frame by sequentially scanning each image line along the scanning direction, wherein scanning each image line includes making the pixels in each image line sensitive to light for a predetermined exposure time, and then determining an intensity readout for each pixel of the respective image line; a lens system configured to project at least two similar outgoing images of an object onto the image sensor, the outgoing images offset from one another in the scanning direction, wherein the outgoing images are projected onto the image sensor such that each pixel of an outgoing image corresponding to a position on the object matches a pixel or group of pixels of another outgoing image corresponding to the respective position on the object; a light generator configured to generate at least two different colours of light, defined by different wavelengths, to illuminate the object; a timing module configured to control the light generator to sequentially generate at least two different colours of light during scanning of a single frame; and a processor configured to identify matched pixels of different outgoing images corresponding to a respective position on the object, and to resolve the colour spectrum of the respective position of the object based on the intensity readout of each matched pixel and the colours of light that the respective matched pixels were exposed to while they were sensitive.
