A camera device according to an embodiment of the present invention a light output unit which outputs output light signals to be emitted to an object; a lens unit which includes an infrared (IR) filter and at least one lens disposed on the IR filter, and focuses input light signals reflected from the object; an image sensor which generates electrical signals from the input light signals focused by the lens unit; an image processing unit which acquires depth information about the object by using the input light signals received in the image sensor; and a control unit which controls the output light signals to be output sequentially for a plurality of light source groups included in the light output unit, and the input light signals to be received sequentially for a plurality of pixel groups included in the light input unit.

Camera device and depth information extraction method of same

According to one embodiment, disclosed is a method for obtaining a depth image for an object, by using light obtained during a first period and a second period in a camera module capable of obtaining depth information. The camera module can obtain the depth image for the object by using the light obtained in a first reception pixel and a second reception pixel during the first period and the second period.

Method for obtaining depth information, and camera module

Disclosed are a sensing method and a sensing apparatus for acquiring information about an object according to one embodiment. In particular, disclosed are a sensing method and a sensing apparatus for obtaining the shape of blood vessels by using information regarding the intensity of received light and information regarding the distance of an object.

Sensing method and apparatus

A camera device is provided. The camera device includes a light emitting portion configured to change a light path of light according to a first control signal and output the light along a first light path or a second light path, a light receiving portion configured to receive the light reflected by an object and generate an electrical signal, and a control portion configured to generate the first control signal which controls the light path of the light to be changed to the first light path or the second light path. Here, the light emitting portion outputs the light with a first pattern along the first light path or outputs the light with a second pattern along the second light path.

Camera device

A camera device according to an embodiment of the present invention includes a light output unit that outputs an output light signal to be irradiated to an object, a lens unit that condenses an input light signal reflected from the object, an image sensor that generates an electric signal from the input light signal condensed by the lens unit and an image processing unit that extracts a depth map of the object using at least one of a time difference and a phase difference between the output light signal and the input light signal received by the image sensor, the lens unit including IR (InfraRed) filter, a plurality of solid lenses disposed on the IR filter and a liquid lens disposed on the plurality of solid lenses, or disposed between the plurality of solid lenses, the camera device further including a first driving unit that controls shifting of the IR filter or the image sensor and a second driving unit that controls a curvature of the liquid lens, an optical path of the input light signal being repeatedly shifted according to a predetermined rule by one of the first driving unit and the second driving unit, and the optical path of the input light signal being shifted according to predetermined control information by the other one of the first driving unit and the second driving unit.
