50 Hz environment), flicker cannot be avoided. The

MT9M114 supports an indoor AE mode, that will ensure

flicker-free operation (VAR8 = 18, 0x0078[0] = 0x1 or

REG = 0xC878[0] = 0x1). The MT9M114 will calculate all

flicker parameters based on the sensor settings which are

programmed in the Cam Control variables. This means the

user only needs to select if 50- or 60-Hz flicker needs to be

avoided (VAR 0x12, 0x008B or R0xC88B = 50 for 50-Hz

flicker avoidance and 60 for 60-Hz avoidance).

Output Conversion and Formatting

The YUV data stream can either exit the color pipeline as

is or be converted before exit to an alternative YUV or RGB

data format.

Color Conversion Formulas

Y’U’V’:

This conversion is BT 601 scaled to make YUV range

from 0 through 255. This setting is recommended for JPEG

encoding and is the most popular, although it is not well

defined and often misused in various operating systems.

There is an option where 128 is not added to U’V’.

Y’Cb’Cr’ Using sRGB Formulas:

The MT9M114 implements the sRGB standard. This

option provides YCbCr coefficients for a correct 4:2:2

transmission.

NOTE:

16 < Y601< 235; 16 < Cb < 240; 16 < Cr < 240;

and 0 < = RGB < = 255.

Y’U’V’ Using sRGB Formulas:

These are similar to the previous set of formulas, but have

YUV spanning a range of 0 through 255.

Uncompressed YUV/RGB Data Ordering

The MT9M114 supports swapping YCbCr mode, as

illustrated in Table 14.

The RGB output data ordering in default mode is shown

in Table 15. The odd and even bytes are swapped when

luma/chroma swap is enabled. R and B channels are bitwise

swapped when chroma swap is enabled.
