HarmonyOS 拍照功能能否直接调用系统相机，还是只有通过Camera kit去自己封装

import common from '@kit.AbilityKit'; 
import Want from '@kit.AbilityKit'; 
let context = getContext(this) as common.UIAbilityContext; 
let want: Want = { 
  action: ‘ohos.want.action.imageCapture’, 
  parameters: { 
    callBundleName: ‘com.example.myapplication’, 
    supportMultiMode: false 
  } 
};

let context = getContext(this) as common.UIAbilityContext; 
let uri:string; 
let want: Want = { 
  action: ‘ohos.want.action.imageCapture’, 
  parameters: { 
    callBundleName: ‘com.example.myapplication’, 
    supportMultiMode: true 
  } 
}; 
context.startAbilityForResult(want, (err, data) => { 
  if (err.code) { 
    console.error(Failed to start ability for result. Code is ${err.code}, message is ${err.message}); 
    return; 
  } 
  console.info(Succeeded in starting ability for result. Data is ${JSON.stringify(data)}); 
  uri = data.want.parameters[‘resourceUri’].toString() //获取相片uri数据 
  console.log(‘uri:’, uri) 
})
