X-scaler

The x-scaler allows up- and downscaling of a scanline.

The x scaling factor is determined by VInSCALING.MX[6:0] and is calculated as

x_scale = VInSCALING.MX[6:0] / 64

MX[6:0] > 64 performs an upscaling, MX < 64 a downscaling. If MX = 0, the x-
scaler is disabled.

Depending on the scaling factor MX/64 a certain number of weighted input pixel
Pyout[x] contribute to the output pixel Pxout[x] at location x:

Pxout[x] = w

+ w

+ ... + w

n

• Pyout

whereas the sum of all weighting factors w

for the input pixel Pyout

equals 1.

The below flow diagram describes the x-scaling process. The shown scaling
process is done for each of the three colour components R, G and B.
The x-scaling process is initialized and started with each new scanline.

Note

Pyout[xin] includes the three colour channels C, i.e. is R or G or B.

Example

Example

In the above example the scaled image shall have a size of (600 x 225) pixels, thus
VInSCALEDWIDTH = 0000 0258

H

and VInSCALEDHEIGHT = 0000 00E1

H

.

The scaled image shall be generated by scaling a rectangle of the size (512 x 300)
pixels from the captured image. Therefore the x-scaling factor is 600/512 = 75/64
(VInSCALING.MX[6:0] = 75), and the y-scaling factor 300/225 = 48/64
(VInSCALING.MY[5:0] = 48). i.e. VInSCALING = 3040 4B40

H

. Note that the divisor

64 is fixed.
