The AR0134CS from ON Semiconductor is a 1/3−inch 1.2 Mp CMOS digital image sensor with an active-pixel array of 1280 (H) x 960 (V). It is designed for low light performance and features a global shutter for accurate capture of moving scenes. It includes sophisticated

camera functions such as auto exposure control, windowing, scaling, row skip mode, and both video and single frame modes. It is programmable through a simple two-wire serial interface. The AR0134CS produces extraordinarily clear, sharp digital pictures, and its ability to capture both continuous video and single frames makes it the perfect choice for a wide range of applications, including scanning and industrial inspection.

The ON Semiconductor AR0134CS can be operated in its default mode or programmed for frame size, exposure, gain, and other parameters. The default mode output is a full-resolution image at 54 frames per second (fps). It outputs 12-bit raw data, using either the parallel or serial (HiSPi) 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 AR0134CS includes additional features to allow application-specific tuning: windowing, adjustable auto-exposure control, auto black level correction, on-board temperature sensor, and row skip and digital binning modes.

The sensor is designed to operate in a wide temperature range (-30°C to +70°C).

 

The AR0134CS 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 50 MHz.

The maximum output pixel rate is 74.25 Mp/s, corresponding to a clock rate of 74.25 MHz. Figure 1（datasheet） shows a block diagram of the sensor.

User interaction with the sensor is through the two-wire serial bus, which communicates with the array control, analog signal chain, and digital signal chain. The core of the sensor is a 1.2 Mp Active-Pixel Sensor array. The AR0134CS features global shutter technology for accurate

capture of moving images. The exposure of the entire array is controlled by programming the integration time by register setting. All rows simultaneously 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.

 

The AR0134CS Global Sensor shutter has a wide array of eatures to enhance functionality and to increase versatility. A summary of features follows. Please refer to the AR0134CS Developer Guide for detailed feature descriptions, register settings, and tuning guidelines and recommendations.

• Operating Modes 

The AR0134CS 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 readouttiming. The exposure time is programmed through the two-wire serial interface for both modes. Trigger mode is not compatible with the HiSPi interface.

• 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.

• Context Switching

Context switching may be used to rapidly switch between two sets of register values. Refer to the AR0134CS Developer Guide for a complete set of context switchable registers.

• Gain

The AR0134CS Global Shutter sensor can be configured for analog gain of up to 8x, and digital gain of up to 8x.

• 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 AR0134CS Developer Guide for more details.

• HiSPi

The AR0134CS Global Shutter image sensor supports two or three lanes of Streaming-SP or Packetized-SP protocols of ON Semiconductor's High-Speed Serial Pixel Interface.

• PLL

An on chip PLL provides reference clock flexibility and supports spread spectrum sources for improved EMI performance.

• Reset

The AR0134CS may be reset by a register write, or by a dedicated input pin.

• Output Enable

The AR0134CS output pins may be tri-stated using a dedicated output enable pin.

• Temperature Sensor

The temperature sensor is only guaranteed to be functional when the AR0134CS is initially powered-up or is reset at temperatures at or above 0°C.

• Black Level Correction

• Row Noise Correction

• Column Correction

• Test Patterns

Several test patterns may be enabled for debug purposes. These include a solid color, color bar, fade to grey, and a walking 1s test pattern.

 

The AR0134CS pixel array is configured as 1412 columns by 1028 rows, (see Figure 2). The dark pixels are optically black and are used internally to monitor black level. Of the right 108 columns, 64 are dark pixels used for row noise correction. Of the top 24 rows of pixels, 12 of the dark rows are used for black level correction. There are 1296 columns by 976 rows of optically active pixels. While the sensor's format is 1280 × 960, the additional active columns and active rows are included for use when horizontal or vertical mirrored readout is enabled, to allow readout to start on the same pixel. The pixel adjustment is always performed for

monochrome or color versions. The active area is surrounded with optically transparent dummy pixels to improve image uniformity within the active area. Not all dummy pixels or barrier pixels can be read out.
