9 This family of formats only store the luma component of a Y'CbCr image. They
10 are often referred to as greyscale formats.
14 - In all the tables that follow, bit 7 is the most significant bit in a byte.
15 - Formats are described with the minimum number of pixels needed to create a
16 byte-aligned repeating pattern. `...` indicates repetition of the pattern.
17 - Y'\ :sub:`x`\ [9:2] denotes bits 9 to 2 of the Y' value for pixel at column
19 - `0` denotes padding bits set to 0.

145 For the Y16 and Y16_BE formats, the actual sampling precision may be lower
146 than 16 bits. For example, 10 bits per pixel uses values in the range 0 to
147 1023. For the IPU3_Y10 format 25 pixels are packed into 32 bytes, which
148 leaves the 6 most significant bits of the last byte padded with 0.
