+ enum:<br>
+ - name: TestPatternModeOff<br>
+ value: 0<br>
+ description: |<br>
+ No test pattern mode is used. The camera device returns frames from<br>
+ the image sensor.<br>
+ - name: TestPatternModeSolidColor<br>
+ value: 1<br>
+ description: |<br>
+ Each pixel in [R, G_even, G_odd, B] is replaced by its respective<br>
+ color channel provided in test pattern data.<br>
+ \todo Add control for test pattern data.<br>
+ - name: TestPatternModeColorBars<br>
+ value: 2<br>
+ description: |<br>
+ All pixel data is replaced with an 8-bar color pattern. The vertical<br>
+ bars (left-to-right) are as follows; white, yellow, cyan, green,<br>
+ magenta, red, blue and black. Each bar should take up 1/8 of the<br>
+ sensor pixel array width. When this is not possible, the bar size<br>
+ should be rounded down to the nearest integer and the pattern can<br>
+ repeat on the right side. Each bar's height must always take up the<br>
+ full sensor pixel array height.<br>
+ - name: TestPatternModeColorBarsFadeToGray<br>
+ value: 3<br>
+ description: |<br>
+ The test pattern is similar to TestPatternModeColorBars,<br>
+ except that each bar should start at its specified color at the top<br>
+ and fade to gray at the bottom. Furthermore each bar is further<br>
+ subdevided into a left and right half. The left half should have a<br>
+ smooth gradient, and the right half should have a quantized<br>
+ gradient. In particular, the right half's should consist of blocks<br>
+ of the same color for 1/16th active sensor pixel array width. The<br>
+ least significant bits in the quantized gradient should be copied<br>
+ from the most significant bits of the smooth gradient. The height of<br>
+ each bar should always be a multiple of 128. When this is not the<br>
+ case, the pattern should repeat at the bottom of the image.<br>
+ - name: TestPatternModePn9<br>
+ value: 4<br>
+ description: |<br>
+ All pixel data is replaced by a pseudo-random sequence generated<br>
+ from a PN9 512-bit sequence (typically implemented in hardware with<br>
+ a linear feedback shift register). The generator should be reset at<br>
+ the beginning of each frame, and thus each subsequent raw frame with<br>
+ this test pattern should be exactly the same as the last.<br>
+ - name: TestPatternModeCustom1<br>
+ value: 5<br>
+ description: |<br>
+ The first custom test pattern. All custom patterns that are<br>
+ available only on this camera device are at least this numeric<br>
+ value. All of the custom test patterns will be static (that is the<br>
+ raw image must not vary from frame to frame).<br>
