Data Structure Name

Description

OHOS::Media::Camera

Provides functions in the Camera class to implement camera operations. operations.

## Functions

Function

Description

OHOS::Media::Camera::~Camera ()=default

virtual

A destructor used to delete the Camera instance.

OHOS::Media::Camera::GetCameraId ()

virtual std::string

Obtains the camera ID.

OHOS::Media::Camera::GetCameraConfig () const

virtual const CameraConfig *

Obtains the camera configuration. You can use the obtained CameraConfig object to configure the camera.

OHOS::Media::Camera::GetFrameConfig (int32_t type)

virtual FrameConfig *

Obtains the frame configuration.

OHOS::Media::Camera::Configure (CameraConfig &config)

virtual void

Configures the camera using the CameraConfig object.

OHOS::Media::Camera::TriggerLoopingCapture (FrameConfig &frameConfig)

virtual int32_t

Triggers looping-frame capture.

OHOS::Media::Camera::StopLoopingCapture ()

virtual void

Stops looping-frame capture.

OHOS::Media::Camera::TriggerSingleCapture (FrameConfig &frameConfig)

virtual int32_t

Starts single-frame capture. The frame parameters are set through the FrameConfig object, and the captured image data is stored in the surface of the FrameConfig object.

OHOS::Media::Camera::Release ()

virtual void

Releases the Camera object and associated resources.

OHOS::Media::Camera::Camera ()=default

A constructor used to create a Camera instance.

## **Details** ## **Function ** ## Camera\(\) ``` OHOS::Media::Camera::Camera () ``` **Description:** A constructor used to create a **[Camera](OHOS-Media-Camera.md)** instance. ## Configure\(\) ``` virtual void OHOS::Media::Camera::Configure ([CameraConfig](OHOS-Media-CameraConfig.md) & config) ``` **Description:** Configures the camera using the **[CameraConfig](OHOS-Media-CameraConfig.md)** object. **Parameters:**

Name

Description
config Indicates the pointer to the CameraConfig object.
## GetCameraConfig\(\) ``` virtual const [CameraConfig](OHOS-Media-CameraConfig.md)* OHOS::Media::Camera::GetCameraConfig () const ``` **Description:** Obtains the camera configuration. You can use the obtained **[CameraConfig](OHOS-Media-CameraConfig.md)** object to configure the camera. **Returns:** Returns the pointer to the **[CameraConfig](OHOS-Media-CameraConfig.md)** object if obtained; returns **NULL** otherwise. ## GetCameraId\(\) ``` virtual std::string OHOS::Media::Camera::GetCameraId () ``` **Description:** Obtains the camera ID. **Returns:** Returns the camera ID if obtained; returns the "Error" string if the camera fails to be created. ## GetFrameConfig\(\) ``` virtual [FrameConfig](OHOS-Media-FrameConfig.md)* OHOS::Media::Camera::GetFrameConfig (int32_t type) ``` **Description:** Obtains the frame configuration. **Parameters:**

Name

Description
type Indicates the type of the frame configuration.
**Returns:** Returns the pointer to the **[FrameConfig](OHOS-Media-FrameConfig.md)** object if obtained; returns **NULL** otherwise. ## Release\(\) ``` virtual void OHOS::Media::Camera::Release () ``` **Description:** Releases the **[Camera](OHOS-Media-Camera.md)** object and associated resources. ## StopLoopingCapture\(\) ``` virtual void OHOS::Media::Camera::StopLoopingCapture () ``` **Description:** Stops looping-frame capture. **Returns:** Returns **true** if the looping-frame capture is successfully stopped; returns **false** otherwise. ## TriggerLoopingCapture\(\) ``` virtual int32_t OHOS::Media::Camera::TriggerLoopingCapture ([FrameConfig](OHOS-Media-FrameConfig.md) & frameConfig) ``` **Description:** Triggers looping-frame capture. **Parameters:**

Name

Description
fc Indicates the frame configuration.
**Returns:** Returns **true** if the looping-frame capture is successfully started; returns **false** otherwise. ## TriggerSingleCapture\(\) ``` virtual int32_t OHOS::Media::Camera::TriggerSingleCapture ([FrameConfig](OHOS-Media-FrameConfig.md) & frameConfig) ``` **Description:** Starts single-frame capture. The frame parameters are set through the **[FrameConfig](OHOS-Media-FrameConfig.md)** object, and the captured image data is stored in the surface of the **[FrameConfig](OHOS-Media-FrameConfig.md)** object. **Parameters:**

Name

Description
fc Indicates the frame configuration.
**Returns:** Returns **true** if the single-frame capture is successfully started and the data is stored; returns **false** otherwise. ## \~Camera\(\) ``` virtual OHOS::Media::Camera::~Camera () ``` **Description:** A destructor used to delete the **[Camera](OHOS-Media-Camera.md)** instance.
