Zoom-out Factor (LSBs). See register
Zoom-in Offset (LSBs). See register
Zoom-out Function Enable
When both Zoom-in and Zoom-out functions are enabled, the STV2310 is in Panorama mode. In Panorama
mode, the ZOOMIN_FACT, the ZOOMOUT_FACT and the ZOOMIN_OFFSET are used. The
ZOOMIN_FACT determines the zoom-in factor at the left and right edges of the picture. The
ZOOMOUT_FACT determines the zoom-out factor at the center of the picture. The ZOOMIN_OFFSET
determines the border width where the zoom factor increases from the zoom-in factor to the zoom-out
factor, starting from the left edge (respectively, the border width finishing on the right edge where the zoom
factor decreases from the zoom-out factor to the zoom-in factor).
Correct programming is left to the user without hardware check. For programming verification, the following
formula must be checked: Zt x (Zout - Zin) = N x (Zout -1)
where Zin = ZOOMIN_FACT; Zout = ZOOMOUT_FACT; Zt = ZOOMIN_OFFSET; N = Number of Y pixels
per line (720 in Normal Pixel mode, 640 or 768 in Square Pixel mode)
0: Zoom-out function is disabled. (Default)
1: Zoom-out function is enabled.
Zoom-in Function Enable
0: Zoom-in function is disabled. (Default)
1: Zoom-in function is enabled.
Coring Function for all standards
The Coring function is operational for all standards. When activated, the demodulated color components (Cr
and Cb) close to 128 are replaced by 128.
00: No action. (Default)
01: 127 to 129 rounded to 128 (dynamic range of ± 1 LSB)
10: 125 to 131 rounded to 128 (dynamic range of ± 3 LSBs)
11: 123 to 133 rounded to 128 (dynamic range of ± 5 LSBs)
NTSC Hue Control Function
The Hue Control mechanism is only operational when the NTSC or NTSC M standard has been detected
(or being tried by the standard identification algorithm). The hue is a fixed offset in a demodulation angle.
The offset is only operational in the active line. There are 63 steps of approximately 1.4 degrees each,
allowing an offset of between -45° and +43.6°.
Coded in 2’s complement (0 = No Hue)
