AR0144/D: 1/4-Inch 1.0 Mp CMOS Digital Image Sensor

General Description

General Description

The ON Semiconductor AR0144 can be operated in its default mode or programmed for

frame size, exposure, gain, and other parameters. The default mode output is a full-reso-

lution image at 60 frames per second (fps). It outputs 12-bit raw data, using either the

parallel or serial (MIPI) output ports. The device may be operated in video (master)

mode or in frame trigger mode.

FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a

synchronized pixel clock. A dedicated FLASH pin can be programmed to control

external LED or flash exposure illumination.

The AR0144 includes additional features to allow application-specific tuning:

windowing, adjustable auto-exposure control, auto black level correction, on-board

temperature sensor, row-skip and column-skip modes and binning modes.

The sensor is designed to operate in a wide temperature range (–40°C to +85°C).

Functional Overview

The AR0144 is a progressive-scan sensor that generates a stream of pixel data at a

constant frame rate. It uses an on-chip, phase-locked loop (PLL) that can be optionally

enabled to generate all internal clocks from a single master input clock running between

6 and 64 MHz. The maximum output pixel rate is 74.25 Mp/s, corresponding to a clock

rate of 74.25 MHz. Figure 1 shows a block diagram of the sensor.

Figure 1: Block Diagram

User interaction with the sensor is through the two-wire serial bus, which communi-

cates with the array control, analog signal chain, and digital signal chain. The core of the

sensor is a 1.0 Mp Active- Pixel Sensor array. The AR0144 features global shutter tech-

nology for accurate capture of moving images. The exposure of the entire array is

controlled by programming the integration time by register setting. All rows simultane-

ously integrate light prior to readout. Once a row has been read, the data from the

columns is sequenced through an analog signal chain (providing offset correction and

gain), and then through an analog-to- digital converter (ADC). The output from the ADC

is a 12-bit value for each pixel in the array. The ADC output passes through a digital

processing signal chain (which provides further data path corrections and applies digital

gain). The pixel data are output at a rate of up to 74.25 Mp/s, in parallel to frame and line

synchronization signals.

Features Overview

The AR0144 Global Shutter sensor has a wide array of features to enhance functionality

and to increase versatility. A summary of features follows. Please refer to the AR0144

Developer Guide for detailed feature descriptions, register settings, and tuning guide-

lines and recommendations.

• 3.0 um Global Shutter Pixel

To improve the low light performance and to capture the moving images accurately a

large (3.0 um) global shutter pixel is implemented for better image optimization.

•Operating Modes

The AR0144 works in master (video), trigger (single frame), or Auto Trigger modes. In

master mode, the sensor generates the integration and readout timing. In trigger

mode, it accepts an external trigger to start exposure, then generates the exposure and

readout timing. The exposure time is programmed through the two-wire serial inter-

face for both modes.

•Window Control

Configurable window size and blanking times allow a wide range of resolutions and

frame rates. Digital binning and skipping modes are supported, as are vertical and

horizontal mirror operations.

•Frame Rate:

AR0144 is capable of running up to 60 fps at full (1280x800) resolution and 66 fps at

720p resolution.

• Embedded Data and Statistics

The AR0144 has the capability to output image data and statistics embedded within

the frame timing.

• Multi-Camera Synchronization

The AR0144 supports advanced line synchronization controls for multi-camera

(stereo) support.

•Slave Mode

The slave mode feature of the AR0144 supports triggering the start of a frame readout

from an input signal that is supplied from an external source. The slave mode signal

allows for precise control of frame rate and register change updates.

• Context Switching and Register Updates

Context switching may be used to rapidly switch between two sets of register values.

Refer to the AR0144 Developer Guide for a complete description of context switchable

registers.

•Gain

A programmable analog gain of 1x to 16x applied globally to all color channels is

available along with a digital gain of 1x to 16x that may be configured on a per color

channel basis.

• Automatic Exposure Control

The integrated automatic exposure control may be used to ensure optimal settings of

exposure and gain are computed and updated every other frame. Refer to the AR0144

Developer Guide for more details.
