Embodiment Construction

[0034] As mentioned earlier, figure 1 is a block diagram of a depth sensor 10 according to one embodiment of the inventive concept. figure 2 is possible to include in figure 1 A plan view of 1-tap depth pixels 23 in array 22 of . image 3 is obtained by cutting along the line I-I' figure 2 A profile obtained by a 1-tap depth pixel of 23, and Figure 4 is shown with figure 1 Timing diagram of the signals related to the operation of the depth sensor 10.

[0035] refer to together figure 1 , figure 2 , image 3 and Figure 4 , the depth sensor 10 is capable of measuring distance or depth using the time-of-flight (TOF) principle. The depth sensor 10 includes: a light source 32 , a lens module 34 , and a semiconductor chip 20 including an array 22 . Assume that array 22 includes a plurality of 1-tap depth pixels (detectors or sensors) 23 .

[0036] The individual 1-tap depth pixels 23 are arranged in a two-dimensional matrix to form the array 22 . Each 1-tap depth pi...

Abstract

The present invention relates to a depth sensor, an image capture method and an image processing system, wherein the image capture method performed by the depth sensor comprises the steps of: transmitting to the scene a first source signal having a first amplitude, and subsequently transmitting to the scene a source signal having a source signal different from the first amplitude capturing a first image in response to the first source signal, and capturing a second image in response to the second source signal; and interpolating the first image and the second image to generate a final image.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0113259 filed on Oct. 12, 2012, the subject matter of which is incorporated herein by reference. technical field [0003] The inventive concepts generally relate to sensors and methods of operating sensors. More particularly, the inventive concept relates to depth information calculation, a depth sensor using a time-of-flight (TOF) principle, an image capturing method using the depth sensor, and an image processing system including the depth sensor. Background technique [0004] A "sensor" is a device that detects the state of an object and converts the detection result into a corresponding electrical signal. Certain sensors are also capable of transmitting corresponding electrical signals to various external circuits. [0005] Sensors include light sensors, temperature sensors, pressure sensors, magnetic sensors, and so-called depth (or dist...
