1 OVERVIEW
This specification defines the interface of camera. The Camera Interface in S5PC100X (Fully Interactive Mobile
Camera interface 4.0) supports ITU R BT-601/656 standard, AXI interface and MIPI (CSI). Maximum input size is
8192 x 8192 pixels. S5PC100x has three CAMERA Interface units as illustrated in Figure 9.3-1. Each of them
consists of several functions. T_patternMux generates test pattern. Test pattern generation is used to calibrate
input sync signals as HREF, and VSYNC. Capture is the capturing signal and window cut. Use register setting to
invert Video sync signals and pixel clock polarity in the camera interface side. Scaler generates various sizes for
useful image. Input DMA (read only) reads from the memory image data. Output DMA (write only) writes image
data to memory. CAMIF has image rotator (90' clockwise) and image effect. These features are very useful in
folder type cellular phone.
