一般的描述
Micron®成像MT9D111是一个1/3.2英寸的200万像素CMOS图像传感器，集成先进的相机系统。相机系统的特点是一个微控制器(MCU)和一个复杂的图像流处理器(IFP)与实时JPEG编码器。它还包括一个可编程通用I/O模块(GPIO)，可用于控制外部自动对焦，光学变焦，或机械快门。
该微控制器管理摄像机系统的所有组件，并为传感器核心设置关键操作参数，以优化输入IFP的原始图像数据的质量。传感器核心包括一个1668 × 1248像素的有源像素阵列，可编程时序和控制电路，包括一个锁相环和外部闪存支持，模拟信号链具有自动偏移校正和可编程增益，以及两个10位a /D转换器(ADC)。整个系统芯片(SOC)具有超低功耗要求和优越的低光性能，特别适用于移动应用。
MT9D111优异的低光性能是DigitalClarity™-Micron的突破性低噪声CMOS成像技术的标志之一，该技术在保持CMOS固有尺寸、成本、功耗和集成优势的同时，实现了CCD图像质量(基于信噪比和低光灵敏度)。
功能概述
MT9D111是一种带有拜耳彩色滤光片排列的彩色图像传感器。其基本特性见表1“关键性能参数”第1页。
MT9D111有一个嵌入式锁相环振荡器(PLL)，可以与普通的无线系统时钟一起使用。在使用时，锁相环调整入射时钟频率，允许MT9D111以几乎任何期望的分辨率和帧速率运行。为了降低功耗，可以绕过锁相环并关闭电源。
低功耗是无线设备所有组件的一个非常重要的要求。MT9D111具有许多节能功能，包括超低功耗待机模式和单独关闭未使用的数字模块的能力。
无线设备的另一个重要考虑因素是它们的电磁发射或干扰(EMI)。MT9D111有一个可编程的I/O转换速率来最小化其EMI和一个输出FIFO来消除输出数据突发。
MT9D111的先进的IFP和灵活的可编程性提供了多种方法来增强和优化图像传感器的性能。内置的优化算法使MT9D111可以作为一款全自动、适应性强的相机在工厂设置下运行。然而，它的大部分设置是用户可编程的。

General Description
Micron® Imaging MT9D111 is a 1/3.2 inch 2-megapixel CMOS image sensor with an integrated advanced camera system. The camera system features a microcontroller (MCU) and a sophisticated image flow processor (IFP) with a real-time JPEG encoder. It also includes a programmable general purpose I/O module (GPIO), which can be used to control external auto focus, optical zoom, or mechanical shutter.
The microcontroller manages all components of the camera system and sets key operation parameters for the sensor core to optimize the quality of raw image data entering the IFP. The sensor core consists of an active pixel array of 1668 x 1248 pixels, programmable timing and control circuitry including a PLL and external flash support, analog signal chain with automatic offset correction and programmable gain, and two 10-bit A/D converters (ADC). The entire system-on-a-chip (SOC) has ultra-low power requirements and superior low-light performance that is particularly suitable for mobile applications.
The excellent low-light performance of MT9D111 is one of the hallmarks of DigitalClarity ™—Micron's breakthrough low-noise CMOS imaging technology that achieves CCD image quality (based on signal-to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost, power consumption, and integration advantages of CMOS.
Feature Overview
The MT9D111 is a color image sensor with a Bayer color filter arrangement. Its basic characteristics are described in Table 1, "Key Performance Parameters," on page 1.
The MT9D111 has an embedded phase-locked loop oscillator (PLL) that can be used with the common wireless system clock. When in use, the PLL adjusts the incoming clock frequency, allowing the MT9D111 to run at almost any desired resolution and frame rate. To reduce power consumption, the PLL can be bypassed and powered down.
Low power consumption is a very important requirement for all components of wireless devices. The MT9D111 has numerous power conserving features, including an ultra-low power standby mode and the ability to individually shut down unused digital blocks.
Another important consideration for wireless devices is their electromagnetic emission or interference (EMI). The MT9D111 has a programmable I/O slew rate to minimize its EMI and an output FIFO to eliminate output data bursts.
The advanced IFP and flexible programmability of the MT9D111 provide a variety of ways to enhance and optimize the image sensor performance. Built-in optimization algorithms enable the MT9D111 to operate at factory settings as a fully automatic, highly adaptable camera. However, most of its settings are user-programmable.
