Image sensing device

Abstract

Distance information is generated using time information corresponding to the peak count values ​​of the difference histogram. [Solution] An image sensing device according to an exemplary embodiment of the present disclosure may include: a pulse signal generation unit that generates a first pulse signal having a first pulse width and a second pulse signal having a second pulse width; a laser pulse transmission unit that transmits a first laser pulse based on the first pulse signal and transmits a second laser pulse based on the second pulse signal; and a distance information generation unit that receives a first reflected pulse generated when the first laser pulse is reflected by an object and a second reflected pulse generated when the second laser pulse is reflected by an object, generates a first histogram based on the first reflected pulse and the second reflected pulse, generates a second histogram based on second image data, and generates distance information about an object based on the difference between the first histogram and the second histogram.
