一、先讲一下一下几个tag作用
1、SENSOR_INFO_PHYSICAL_SIZE:全像素组的物理尺寸
2、SENSOR_INFO_PIXEL_ARRAY_SIZE：全像素阵列包括黑色校准像素和其他非活动区域
3、SENSOR_INFO_ACTIVE_ARRAY_SIZE:图像传感器的区域对应于活跃像素经过任何几何失真校正后的应用，基于SENSOR_INFO_PIXEL_ARRAY_SIZE
4、SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE:图像传感器区域，相当于在几何失真校准前的活跃像素
二、为限制厂家进行差值，为何限制差值，哎，我买了瓶酒，怎么兑水了
因此增加了tag2 和3
对于 2 3 4 tag的有何要求；
SENSOR_INFO_ACTIVE_ARRAY_SIZE <= SENSOR_INFO_PIXEL_ARRAY_SIZE
SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE <= SENSOR_INFO_PIXEL_ARRAY_SIZE
具体cts代码:StaticMetadata.java
/* Get and check pre-correction active array size.*/
public Rect getPreCorrectedActiveArraySizeChecked() {
Key<Rect> key = CameraCharacteristics.SENSOR_INFO_PRE_CORRECTION_ACTIVE_ARRAY_SIZE;
Rect activeArray = getValueFromKeyNonNull(key);
if (activeArray == null) {
return new Rect(0, 0, 0, 0);
}
Size pixelArraySize = getPixelArraySizeChecked();
checkTrueForKey(key, "values left/top are invalid", activeArray.left >= 0 && activeArray.top >= 0);
checkTrueForKey(key, "values width/height are invalid",
activeArray.width() <= pixelArraySize.getWidth() &&
activeArray.height() <= pixelArraySize.getHeight());
return activeArray;
}
/**Get and check active array size./
public Rect getActiveArraySizeChecked() {
Key<Rect> key = CameraCharacteristics.SENSOR_INFO_ACTIVE_ARRAY_SIZE;
Rect activeArray = getValueFromKeyNonNull(key);
if (activeArray == null) {
return new Rect(0, 0, 0, 0);
}
Size pixelArraySize = getPixelArraySizeChecked();
checkTrueForKey(key, "values left/top are invalid", activeArray.left >= 0 && activeArray.top >= 0);
checkTrueForKey(key, "values width/height are invalid",
activeArray.width() <= pixelArraySize.getWidth() &&
activeArray.height() <= pixelArraySize.getHeight());
return activeArray;
}
