+ 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: 5
+ 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).
