摘要： In a distance measurement device of an embodiment, a light source emits modulation light in a first charge transfer cycle, and emission of the modulation light of the light source is stopped in a second charge transfer cycle. In each of the first and second charge transfer cycles, the charges generated in a photosensitive region are distributed to a first accumulation region and a second accumulation region. A first value is obtained based on readout values corresponding to amounts of accumulated charges of the first accumulation region. A second value is obtained based on readout values corresponding to amounts of accumulated charges of the second accumulation region. A distance is calculated based on the first value and the second value.

摘要： Two charge quantities (Q1,Q2) are output from respective pixels P (m,n) of the back-illuminated distance measuring sensor 1 as signals d′(m,n) having the distance information. Since the respective pixels P (m,n) output signals d′(m,n) responsive to the distance to an object H as micro distance measuring sensors, a distance image of the object can be obtained as an aggregate of distance information to respective points on the object H if reflection light from the object H is imaged on the pickup area 1B. If carriers generated at a deep portion in the semiconductor in response to incidence of near-infrared light for projection are led in a potential well provided in the vicinity of the carrier-generated position opposed to the light incident surface side, high-speed and accurate distance measurement is enabled.
