}

Control to select the test pattern mode. Currently identical to ANDROID_SENSOR_TEST_PATTERN_MODE.

Variants

Off = 0

No test pattern mode is used. The camera device returns frames from the image sensor.

SolidColor = 1

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.

ColorBars = 2

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.

ColorBarsFadeToGray = 3

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.

Pn9 = 4

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.

Custom1 = 256

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).

Trait Implementations

impl Clone for TestPatternMode

fn clone(&self) -> TestPatternMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ControlEntry for TestPatternMode

const ID: u32 = 48u32

impl Debug for TestPatternMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<TestPatternMode> for ControlValue

fn from(val: TestPatternMode) -> Self

Converts to this type from the input type.

impl From<TestPatternMode> for i32

fn from(enum_value: TestPatternMode) -> Self

Converts to this type from the input type.

impl PartialEq for TestPatternMode

fn eq(&self, other: &TestPatternMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<ControlValue> for TestPatternMode

type Error = ControlValueError

The type returned in the event of a conversion error.

fn try_from(value: ControlValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<i32> for TestPatternMode

type Error = TryFromPrimitiveError<TestPatternMode>

The type returned in the event of a conversion error.
