和你一起终身学 习，这里是程序员Android

经典好文推荐，通过阅读本文，您将收获以下知识点:

一、In-sensor zoom 概述

二、如何开启 In-sensor zoom

2.1 开启 camxsettings.xml setting

2.2 多摄像头，需要添加特殊的逻辑

2.3 在 MetaTransitionTable 配置 sensorModeGroupId 的范围

2.4 在Sensor.xml 中设置兼容性 INSENSORZOOM

2.5 InSensor zoom log

一、In-sensor zoom 概述

InSensor Zoom 不仅需要高通平台支持，而且需要Camera sensor 模组支持(需要跟Sensor FAE 确认)。
与正常的zoom 对比，Insensor zoom 使用full remosaic size mode 替换1/4 binng mode, 当zoom > 2x, sensor crop输出2x zoom.

二、如何开启 In-sensor zoom

2.1 开启 camxsettings.xml setting

vendor/qcom/proprietary/camx-common/settings/common/camxsettings.xml

设置 Enable In Sensor Zoom DefaultValue

go 复制代码

<setting>
   <Name>Enable In Sensor Zoom</Name>
   <Help>Settings to enable In sensor Zoom</Help>
   <VariableName>enableInSensorZoom</VariableName>
   <VariableType>BOOL</VariableType>
   <SetpropKey>vendor.debug.camera.enableInSensorZoom</SetpropKey>
   // 设置  Enable In Sensor Zoom DefaultValue 
   <DefaultValue>TRUE</DefaultValue>
   <Dynamic>FALSE</Dynamic>
   <Public>TRUE</Public>
 </setting>

2.2 多摄像头，需要添加特殊的逻辑

oem/qcom/multicamera/chimcxcameraconfig/configs/netrani/netrani.xml

配置 SensorMode Group id 是否否支持 Insensor zoom 1 支持、0 不支持

go 复制代码

<!-- Transition Modes ============================================================== ====================-->
    <TransitionMode id="0" sensorModeGroupId="0" skipRate="0" physicalDeviceRef="UltrawidePhysicalCam" />
    <TransitionMode id="1" sensorModeGroupId="0" skipRate="0" physicalDeviceRef="WidePhysicalCam" />
    <TransitionMode id="2" sensorModeGroupId="0" skipRate="0" physicalDeviceRef="TelePhysicalCam" />
    <TransitionMode id="3" sensorModeGroupId="1" skipRate="0" physicalDeviceRef="WidePhysicalCam" />
    <TransitionMode id="4" sensorModeGroupId="1" skipRate="0" physicalDeviceRef="TelePhysicalCam" />
    <!-- Transition Tables ==================================================================================-->

2.3 在 MetaTransitionTable 配置 sensorModeGroupId 的范围

go 复制代码

<MetaTransitionTable id="2" metadata="zoomRatio" type="Float">
        <Transition  activeRangeStart="0.6" activeRangeEnd="0.9999"  hysteresisMinFactor="0.0" hysteresisMaxFactor="0.0" transition_modes="(0)"/>
        <Transition  activeRangeStart="1.0" activeRangeEnd="1.9999"  hysteresisMinFactor="0.0" hysteresisMaxFactor="0.0" transition_modes="(1)"/>
        <Transition  activeRangeStart="2.0" activeRangeEnd="2.9999"  hysteresisMinFactor="0.0" hysteresisMaxFactor="0.0" transition_modes="(3)"/>
        <Transition  activeRangeStart="3.0" activeRangeEnd="6.0999"  hysteresisMinFactor="0.0" hysteresisMaxFactor="0.0" transition_modes="(2)"/>
        <Transition  activeRangeStart="6.1" activeRangeEnd="120.01"  hysteresisMinFactor="0.0" hysteresisMaxFactor="0.0" transition_modes="(4)"/>
    </MetaTransitionTable>

2.4 在Sensor.xml 中设置兼容性 INSENSORZOOM

找FAE 要Sensor FAE 要一组支持remosaic 的insensor zoom 的 resolution

go 复制代码

<!--res5 4624x3472_30fps for QCFA insensorzoom mode with remosaic enable -->
     <!--Frame dimension: contains xStart, yStart, width and height -->
     <frameDimension>
       <xStart>  </xStart>
       <yStart> </yStart>
       <width>4624</width>
       <height>3472</height>
     </frameDimension>
     
      <!--List of features / capabilities supported by sensor -->
      <capability>INSENSORZOOM</capability>
      <transitionGroups>BINCROP43 BINCROP169</transitionGroups>
      <RemosaicTypeInfo>NoRemosaic</RemosaicTypeInfo>

2.5 InSensor zoom log

log 关键字：
SetInSensorZoomInfo|PublishPerFrameSensorMetaData .*resID|ApplySensorUpdate

bEnableInSensorZoomMode: 1 表示成功开启Insensor Zooom

触发Insensorroom 后会切换对应的senmode 的resolution(比如：从 mode 1-->mode 5 bEnableInSensorZoomMode: 1 )

go 复制代码

bEnableInSensorZoomMode: 1 
 01-01 18:53:41.468933  1501 11723 I CHIUSECASE: [CORE_CFG ] chifeature2graphselector.cpp:7391 SetInSensorZoomInfo() [InSensorZoom] cameraId:0 bEnableInSensorZoomMode: 0zoomStatusChanged = 0 requested zoomState: 1 m_inSensorZoomInfo.zoomState 1 appFrameIndex 91 size 3
