Image Scaling and Cropping
To ensure that the size of images output by the MT9M114 can be tailored to the needs of
all users, the IFP includes a scaler module. When enabled, this module performs resca-
ling of incoming images—shrinks them to the selected width (the output widths should
be in multiples of 4) and height without reducing the field of view and without
discarding any pixel values.
By configuring the cropped and output windows to various sizes, different zooming
levels for 4X, 2X, and 1X can be achieved. The location of the cropped window is config-
urable so that panning is also supported. The height and width definitions for the output
window must be equal to or smaller than the cropped image. The image cropping and
scaler module can be used together to implement a digital zoom and pan.
Hue Rotate
The MT9M114 has integrated hue rotate. This feature will help for improving the color
image quality and give customers the flexibility for fine color adjustment and special
color effects.

Name
Hue Angle
Function
Adjusts the global hue angle adjustment.
0xEA = –22
0x00 = 0
0x16 = +22
Vertical Perspective Correction
The MT9M114 has vertical perspective correction (VPC) also known as the Tilt Connec-
tion; this allows the user to correct (within limits) for an off-horizontal axis camera.
