In one aspect, a method may include a time-of-flight (TOF) system configured to emit light and sense a reflection of the emitted light and may determine a return energy based on the reflection of the emitted light. The method may measure a time between when the light is emitted and when the reflection is sensed and may determine a distance between the target object and the TOF system based on that time. The method may also identify a reflectance of the target object based on the return energy and may determine an exposure level based on a distance between the target object and a reflectance of the target object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for performing exposure estimation using a time-of-flight sensor","description":"This application relates to capturing an image of a target object using information from a time-of-flight sensor.
