A distance image capturing device includes a distance image processing unit, that drives pixels with three driving patterns consisting of a first pattern, a second pattern, and a third pattern, calculates a flare light reception timing at which flare light is received in the first pattern, controls an emission timing such that the flare light reception timing and a gate opening and closing timing are the same timing, in the second pattern, controls such that an emission period is shorter than an emission period in the second pattern, in the third pattern, and calculates a flare signal amount corresponding to a light amount of the flare light received by a pixel, by using a subtraction value obtained by subtracting a storage signal in the third pattern from a storage signal in the second pattern to calculate a distance to an object by using the calculated flare signal amount.
A distance image capturing device comprising:
A distance image capturing method performed by a distance image capturing device including a light source unit that irradiates an optical pulse to a space to be measured, a light receiving unit having a pixel including a photoelectric conversion element that generates charges according to light incident from the space to be measured and a plurality of charge storage units that store the charges, and a pixel drive circuit that performs driving of storing the charges in each of the charge storage units, and a distance image processing unit that controls the pixel drive circuit such that the charges are distributed to the charge storage units and stored in each of the charge storage units at a storage timing synchronized with an emission timing of emitting the optical pulse, and calculates a distance to an object based on an amount of charges stored in each of the charge storage units, the method comprising:
