12.5 DESCRIPTION OF SUPPORTED COLOR FORMAT
JPEG supports several color formats during compression/ decompression.
12.5.1 IN COMPRESSION MODE
Before compression starts, raw image data must be in main memory. The raw image data address is specified in
IMGADR register. The raw images are stored in interleaved YCbCr4:2:2 or RGB565 color format as shown in
Figure 12-3
. After compression is complete, result file is baseline JPEG in YCbCr4:2:0 or YCbCr4:2:2 format with
interleaved scan. Therefore color space conversion (RGB
Æ
YCbCr) and decimation of chrominance component is
necessary. JPEG IP has its own color space converter. COEF1, COEF2 and COEF3 register sets the coefficients
of color space converter. Decimation of JPEG IP is downsampling process. For example, decimation from
YCbCr4:2:2 to YCbCr4:2:0 needs 2:1 vertical downsampling for Cb and Cr component as shown in
Figure 12-4
.
12.5.2 IN DECOMPRESSION MODE
In decompression mode, input file is baseline JPEG in YCbCr4:4:4, YCbCr4:2:2, YCbCr4:2:0, gray with
interleaved scan and output raw image has interleaved YCbCr4:2:2 or YCbCr4:2:0 formats. Therefore for input file
with YCbCr format, decimation and interpolation process is done during decompression. In this case, decimation
is same as downsampling and interpolation is sample-and-hold (repetition of recent value) process. Each
operation is described in
Figure 12-3.
The result of gray format JPEG file input is YCbCr4:2:2 or YCbCr4:2:0 raw
images. This raw images have Y component, which is result of decompression, and Cb and Cr component with
“128” value.
