Light Source Module with Integrated Ambient Light Sensing Capability - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240267633 titled 'Light Source Module with Integrated Ambient Light Sensing Capability

Simplified Explanation: The patent application describes a light source module integrated into a portable computing device that includes light emitters and light sensors sharing an aperture. One of the light sensors measures illuminance passing through the aperture and sends a signal indicating the measurement to a controller in the device. The controller uses this information to adjust device operations such as display brightness and camera auto-exposure.

Light source module with light emitters and light sensors sharing an aperture
Measurement of illuminance passing through the aperture, not from the light emitters
Integration into a portable computing device with a controller
Controller adjusts device operations based on illuminance measurement
Calibration process to determine parameters for interpreting the signal

Potential Applications: 1. Smartphones and tablets with automatic brightness adjustment based on ambient light conditions 2. Cameras with auto-exposure features that adapt to varying lighting environments 3. Wearable devices with display brightness control for improved user experience

Problems Solved: 1. Inconsistent display brightness in changing lighting conditions 2. Manual adjustment of camera settings in different light settings 3. Lack of integration of light sensors for optimizing device performance

Benefits: 1. Enhanced user experience with devices that adapt to ambient lighting 2. Improved image quality in varying light conditions 3. Energy efficiency by optimizing display brightness based on ambient light levels

Commercial Applications: Optimizing display brightness and camera settings in smartphones, tablets, cameras, and wearable devices can lead to improved user satisfaction and performance in various lighting conditions.

Questions about Light Source Module: 1. How does the light source module in the patent application differ from traditional light sensors in devices? 2. What are the potential implications of integrating light sensors into portable computing devices for user experience and device performance?

Original Abstract Submitted

various embodiments include a light source module with one or more light emitters and one or more light sensors that share an aperture via which light passes. one of the light sensors may measure illuminance received through the aperture (not illuminance from the light emitters) and send a signal indicating a measurement of the illuminance. the light source module may be integrated into a portable computing device having a controller. the controller may include logic to perform one or more device operations based on the measurement of illuminance, such as, but not limited to, controlling a device display brightness and/or controlling an auto exposure feature of the device camera. calibration parameters for interpreting the signal may be determined via a calibration process.
