A sensor chip , comprising: a light reception section configured to receive light projected from a light source and reflected by an imaging object to detect, for each given detection period, a reception light amount of the reflected light within the given period; a measurement section configured to measure a distance to the imaging object based on the reception light amount; and a control section configured to apply a first delay amount and a second delay amount, wherein the first delay amount is applied in a unit of a first time length (tdl) and the second delay amount is applied in a unit of a second time length (td2), where the first time length (tdl) and the second time length (td2) are different from each other, to control of a first timing (I 11 ; I 12 ) at which the light reception section is to detect the reception light amount thereby to control a relative time difference between the first timing and a second timing (I 11 ; I 12 ) at which the light source is to project light with a resolution finer than the unit of the first time length (td1)of the first delay amount and the unit of the second time length (td2) of the second delay amount by satisfying the relationship td1 - td2 < td2 < td1, wherein td1 is the unit of the first time length (td1) and td2 is the unit of the second time length (td2), in response to the first delay amount and the second delay amount, wherein the first delay amount is applied to the first timing (I 11 ; I 12 ) and is controlled in a unit of the first time length (td1), and the second delay amount is applied to the second timing (I 11 ; I 12 ) and is controlled in a unit of the second time length (td2). a light reception section configured to receive light projected from a light source and reflected by an imaging object to detect, for each given detection period, a reception light amount of the reflected light within the given period; a measurement section configured to measure a distance to the imaging object based on the reception light amount; and a control section configured to apply a first delay amount and a second delay amount, wherein the first delay amount is applied in a unit of a first time length (tdl) and the second delay amount is applied in a unit of a second time length (td2), where the first time length (tdl) and the second time length (td2) are different from each other, to control of a first timing (I 11 ; I 12 ) at which the light reception section is to detect the reception light amount thereby to control a relative time difference between the first timing and a second timing (I 11 ; I 12 ) at which the light source is to project light with a resolution finer than the unit of the first time length (td1)of the first delay amount and the unit of the second time length (td2) of the second delay amount by satisfying the relationship td1 - td2 < td2 < td1, wherein td1 is the unit of the first time length (td1) and td2 is the unit of the second time length (td2), in response to the first delay amount and the second delay amount, wherein the first delay amount is applied to the first timing (I 11 ; I 12 ) and is controlled in a unit of the first time length (td1), and the second delay amount is applied to the second timing (I 11 ; I 12 ) and is controlled in a unit of the second time length (td2). <EOS>
