38. Image Sensor Interface (ISI)

Figure 38-1. ISI Connection Example
6221I–ATARM–17-Jul-09
Description
The Image Sensor Interface (ISI) connects a CMOS-type image sensor to the processor and
provides image capture in various formats. It does data conversion, if necessary, before the stor-
age in memory through DMA.
The ISI supports color CMOS image sensor and grayscale image sensors with a reduced set of
functionalities.
In grayscale mode, the data stream is stored in memory without any processing and so is not
compatible with the LCD controller.
Internal FIFOs on the preview and codec paths are used to store the incoming data. The RGB
output on the preview path is compatible with the LCD controller. This module outputs the data
in RGB format (LCD compatible) and has scaling capabilities to make it compliant to the LCD
display resolution (See
Several input formats such as preprocessed RGB or YCbCr are supported through the data bus
interface.
It supports two modes of synchronization:
Using EAV/SAV for synchronization reduces the pin count (ISI_VSYNC, ISI_HSYNC not used).
The polarity of the synchronization pulse is programmable to comply with the sensor signals.
