A display device (10) according to the present disclosure includes: a detection unit (11) that detects, in a three-dimensional space including measurement point group data measured by a three-dimensional optical sensor, intermediate point group data of an intermediate region from a viewpoint for two-dimensionally displaying the measurement point group data to target point group data within the measurement point group data; a setting unit (12) that sets, based on the detected intermediate point group data, a display aspect of the measurement point group data or the target point group data in such a way that the target point group data become visually recognizable from the viewpoint; and a display unit (13) that two-dimensionally displays the measurement point group data and the target point group data according to the set display aspect.

An information processing system includes an object information generator and an output unit. The object information generator generates object information. A piece of the object information indicates a feature of an object present in a target distance section. The target distance section is one selected from a plurality of distance sections defined by dividing the distance measurable range in accordance with differences in elapsed times from a point of time when a light emitting unit emits a measuring light. The object information generator generates the piece of the object information based on a distance section signal associated with the target distance section. The output unit outputs the object information.

The disclosed photoelectric conversion device includes a pixel including a photoelectric conversion unit, an AD conversion unit that performs an AD conversion on an analog signal generated in the pixel, and a control unit configured to control the AD conversion unit. The control unit is configured to control the AD conversion unit to perform a plurality of times of the AD conversion on the same analog signal. A length of a first AD conversion period of the plurality of times is shorter than a length of a second AD conversion period of the plurality of times. A change rate of the reference signal in the second AD conversion period is smaller than a change rate of the reference signal in the first AD conversion period. In each of the first and second AD conversion periods, a potential of the reference signal changes to a first level.

The present invention provides a laser ranging apparatus, including: a holder, a measuring part mounted to the holder, and a housing detachably connected to the holder, wherein the housing includes a first casing. The first casing is an integrally formed tubular structure detachably sleeved outside the holder. An advantage of the present invention is to provide a laser ranging apparatus for fixedly mounting a measuring component on a holder and installing a detachable casing on the outside of the holder so as to ensure that the position of the measuring component will not be moved during the disassembly and assembly of the casing and the ranging precision of the measuring part will not be affected. The casing is composed of several simple components, which can effectively reduce the process difficulty of the casing parts. Meanwhile, the assembly and disassembly of the casing are simple and convenient, the production efficiency is increased effectively, the production cost is reduced, and the productivity is increased. The laser ranging apparatus has a smaller size, compact structure, less space occupied, easy for users to carry, and good anti-shock performance and hand feeling.

Embodiments may relate to a graphical user interface (GUI). The GUI may include a first portion that displays an image related to images of a location. The GUI may also include a second portion that displays an image related to detection and ranging information of the location. The two images may be linked such that an interaction with an object in one portion of the GUI causes changes in the other portion of the GUI. Other embodiments may be described or claimed.
