controls:

Mode of operation for the noise reduction algorithm.
enum:
- name: NoiseReductionModeOff
value: 0
description: No noise reduction is applied
- name: NoiseReductionModeFast
value: 1
description: |

- name: NoiseReductionModeHighQuality

value: 4
description: |

description: |
High quality aberration correction which might reduce the frame
rate.
- AeState:
type: int32_t
description: |
Control to report the current AE algorithm state. Currently identical to
ANDROID_CONTROL_AE_STATE.
Current state of the AE algorithm.
enum:
- name: AeStateInactive
value: 0
description: The AE algorithm is inactive.
- name: AeStateSearching
value: 1
description: The AE algorithm has not converged yet.
- name: AeStateConverged
value: 2
description: The AE algorithm has converged.
- name: AeStateLocked
value: 3
description: The AE algorithm is locked.
- name: AeStateFlashRequired
value: 4
description: The AE algorithm would need a flash for good results
- name: AeStatePrecapture
value: 5
description: |
The AE algorithm has started a pre-capture metering session.
\sa AePrecaptureTrigger
- AwbState:
type: int32_t
description: |
Control to report the current AWB algorithm state. Currently identical
to ANDROID_CONTROL_AWB_STATE.
Current state of the AWB algorithm.
enum:
- name: AwbStateInactive
value: 0
description: The AWB algorithm is inactive.
- name: AwbStateSearching
value: 1
description: The AWB algorithm has not converged yet.
- name: AwbConverged
value: 2
description: The AWB algorithm has converged.
- name: AwbLocked
value: 3
description: The AWB algorithm is locked.
- SensorRollingShutterSkew:
type: int64_t
description: |
Control to report the time between the start of exposure of the first
row and the start of exposure of the last row. Currently identical to
ANDROID_SENSOR_ROLLING_SHUTTER_SKEW
- LensShadingMapMode:
type: int32_t
description: |
Control to report if the lens shading map is available. Currently
identical to ANDROID_STATISTICS_LENS_SHADING_MAP_MODE.
enum:
- name: LensShadingMapModeOff
value: 0
description: No lens shading map mode is available.
- name: LensShadingMapModeOn
value: 1
description: The lens shading map mode is available.
- PipelineDepth:
type: int32_t
description: |
Specifies the number of pipeline stages the frame went through from when
it was exposed to when the final completed result was available to the
framework. Always less than or equal to PipelineMaxDepth. Currently
identical to ANDROID_REQUEST_PIPELINE_DEPTH.
The typical value for this control is 3 as a frame is first exposed,
captured and then processed in a single pass through the ISP. Any
additional processing step performed after the ISP pass (in example face
detection, additional format conversions etc) count as an additional
pipeline stage.
- MaxLatency:
type: int32_t
description: |
The maximum number of frames that can occur after a request (different
than the previous) has been submitted, and before the result's state
becomes synchronized. A value of -1 indicates unknown latency, and 0
indicates per-frame control. Currently identical to
ANDROID_SYNC_MAX_LATENCY.
- TestPatternMode:
type: int32_t
description: |
Control to select the test pattern mode. Currently identical to
ANDROID_SENSOR_TEST_PATTERN_MODE.
enum:
- name: TestPatternModeOff
value: 0
description: |
No test pattern mode is used. The camera device returns frames from
the image sensor.
- name: TestPatternModeSolidColor
value: 1
description: |
Each pixel in [R, G_even, G_odd, B] is replaced by its respective
color channel provided in test pattern data.
\todo Add control for test pattern data.
- name: TestPatternModeColorBars
value: 2
description: |
All pixel data is replaced with an 8-bar color pattern. The vertical
bars (left-to-right) are as follows; white, yellow, cyan, green,
magenta, red, blue and black. Each bar should take up 1/8 of the
sensor pixel array width. When this is not possible, the bar size
should be rounded down to the nearest integer and the pattern can
repeat on the right side. Each bar's height must always take up the
full sensor pixel array height.
- name: TestPatternModeColorBarsFadeToGray
value: 3
description: |
The test pattern is similar to TestPatternModeColorBars,
except that each bar should start at its specified color at the top
and fade to gray at the bottom. Furthermore each bar is further
subdevided into a left and right half. The left half should have a
smooth gradient, and the right half should have a quantized
gradient. In particular, the right half's should consist of blocks
of the same color for 1/16th active sensor pixel array width. The
least significant bits in the quantized gradient should be copied
from the most significant bits of the smooth gradient. The height of
each bar should always be a multiple of 128. When this is not the
case, the pattern should repeat at the bottom of the image.
- name: TestPatternModePn9
value: 4
description: |
All pixel data is replaced by a pseudo-random sequence generated
from a PN9 512-bit sequence (typically implemented in hardware with
a linear feedback shift register). The generator should be reset at
the beginning of each frame, and thus each subsequent raw frame with
this test pattern should be exactly the same as the last.
- name: TestPatternModeCustom1
value: 256
description: |
The first custom test pattern. All custom patterns that are
available only on this camera device are at least this numeric
value. All of the custom test patterns will be static (that is the
raw image must not vary from frame to frame).
