A measurement apparatus comprising: a light reception section including a light reception element group including plural light reception elements included in a target region; a control section that controls a first light reception element group and a second light reception element group included in the light reception element group, so as to read out the first light reception element group and the second light reception element group during periods different from each other; and a signal processing section that performs signal processing on a basis of a signal read out from at least one of the first light reception element group and the second light reception element group, wherein a sum set of the first light reception element group and the second light reception element group includes all of the plural light reception elements, and at least part of the first light reception element group is not included in the second light reception element group, the plural light reception elements are arrayed in a two-dimensional grid pattern to form the light reception element group, and the control section sequentially reads out plural first scanning ranges each including plural lines that are included in the first light reception element group and are arranged successively in a column direction of the array of the two-dimensional grid pattern, and, after the reading out of the plural first scanning ranges, sequentially reads out plural second scanning ranges each including plural lines that are included in the second light reception element group and are arranged successively in the column direction, characterized in that the control section further sets a distance between the plural first scanning ranges, the number of lines included in each of the plural first scanning ranges, a distance between the plural second scanning ranges, and the number of lines included in each of the plural second scanning ranges independently of each other. a light reception section including a light reception element group including plural light reception elements included in a target region; a control section that controls a first light reception element group and a second light reception element group included in the light reception element group, so as to read out the first light reception element group and the second light reception element group during periods different from each other; and a signal processing section that performs signal processing on a basis of a signal read out from at least one of the first light reception element group and the second light reception element group, wherein a sum set of the first light reception element group and the second light reception element group includes all of the plural light reception elements, and at least part of the first light reception element group is not included in the second light reception element group, the plural light reception elements are arrayed in a two-dimensional grid pattern to form the light reception element group, and the control section sequentially reads out plural first scanning ranges each including plural lines that are included in the first light reception element group and are arranged successively in a column direction of the array of the two-dimensional grid pattern, and, after the reading out of the plural first scanning ranges, sequentially reads out plural second scanning ranges each including plural lines that are included in the second light reception element group and are arranged successively in the column direction, characterized in that the control section further sequentially reads out plural first scanning ranges each including plural lines that are included in the first light reception element group and are arranged successively in a column direction of the array of the two-dimensional grid pattern, and, after the reading out of the plural first scanning ranges, sequentially reads out plural second scanning ranges each including plural lines that are included in the second light reception element group and are arranged successively in the column direction, characterized in that the control section further sets a distance between the plural first scanning ranges, the number of lines included in each of the plural first scanning ranges, a distance between the plural second scanning ranges, and the number of lines included in each of the plural second scanning ranges independently of each other.
