Distance image capturing device and distance image capturing method

A distance image capturing method performed by a distance image capturing device including a light source unit that irradiates a measurement space with a light pulse;

• a light receiving unit having a pixel including a photoelectric conversion element that generates charges according to incident light and a plurality of charge storage units that store the charges, and a pixel drive circuit that distributes the charges to the charge storage units and stores the charges in each of the charge storage units at a predetermined storage timing synchronized with an emission timing of emitting the light pulse;
• and a distance image processing unit that calculates a distance to an object existing in the measurement space, based on an amount of the charges stored in each of the charge storage units, the method comprising:
• via the distance image processing unit
• providing a plurality of storage cycles in one frame;
• performing control such that in the plurality of storage cycles, the charges are stored in each of the charge storage units at any timing among storage timings of which the number is larger than a number of the charge storage units included in the pixel;
• performing control such that a total number of times, which is a sum of times the charges are stored in each of the charge storage units, becomes the same in the one frame;
• and
• performing control such that a time difference between a first storage timing and a second storage timing is a time different from a storage time for storing the charges in each of the charge storage units, the first storage timing being a storage timing for storing the charges in a specific charge storage unit among the plurality of charge storage units in a specific storage cycle among the plurality of storage cycles, and the second storage timing being a storage timing for storing the charges in the specific charge storage unit in another storage cycle different from the specific storage cycle.
