General Description
The ON Semiconductor MT9V023 is a 1/3-inch wide-VGA format CMOS active-pixel digital image sensor with global shutter and high dynamic range (HDR) operation. The sensor has specifically been designed to support the demanding interior and exterior automotive imaging needs, which makes this part ideal for a wide variety of imaging applications in real-world environments.
This wide-VGA CMOS image sensor features ON Semiconductor'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, and integration advantages of CMOS.
The active imaging pixel array is 752H x 480V. It incorporates sophisticated camera functions on-chip-such as binning 2 x 2 and 4 x 4, to improve sensitivity when operating in smaller resolutions-as well as windowing, column and row mirroring. It is programmable through a simple two-wire serial interface.
The MT9V023 can be operated in its default mode or be programmed for frame size, exposure, gain setting, and other parameters. The default mode outputs a wide-VGA-size image at 60 frames per second (fps).
An on-chip analog-to-digital converter (ADC) provides 10 bits per pixel. A 12-bit resolution companded for 10 bits for small signals can be alternatively enabled, allowing more accurate digitization for darker areas in the image.
In addition to a traditional, parallel logic output the MT9V023 also features a serial lowvoltage differential signaling (LVDS) output. The sensor can be operated in a stereocamera, and the sensor, designated as a stereo-master, is able to merge the data from itself and the stereo-slave sensor into one serial LVDS stream.
The sensor is designed to operate in a wide temperature range (–40°C to +105°C).
Pixel Data Format
Pixel Array Structure
The MT9V023 pixel array is configured as 809 columns by 499 rows,
The dark pixels are optically black and are used internally to monitor black level. Of the left 52 columns, 36 are dark pixels used for row noise correction. Of the top 14 rows of pixels, two of the dark rows are used for black level correction. Also, three black rows from the top black rows can be read out by setting the Show Dark Rows bit in the Read Mode register; setting Show Dark Columns will display the 36 dark columns. There are 753 columns by 481 rows of optically active pixels. While the sensor's format is 752 x 480, one additional active column and active row are included for use when horizontal or vertical mirrored readout is enabled, to allow readout to start on the same pixel. This one 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. Neither dummy pixels nor barrier pixels can be read out.
5 Reasons the MT9V023 is Ideal for Automotive Systems
(1)，Reliable Operation in Extreme Temperatures
The-40 to +105°C operating range meets AEC-Q100, specifications, ensuring optimum performance in harsh environments.
(2)，Context Switching for Simultaneous Applications
An additional register bank provides the ability to run two different imaging applications simultaneously from a single sensor.
(3)，Wide Dynamic Range for Superb High-Contrast Imaging
Extended knee-points provide greater control and excellent output for excellent output in high-contrast conditions.
(4)，Accurate Fast-Motion Capture
The fine shutter control (via sub-row integration) of our TrueSNAP TM global shutter enables fast-moving object capture without image tearing.
(5)，Small Footprint
Measuring just 9 millimeters square, the MT9V023’s automotive-grade ball grid array (BGA) package is one of thesmallest in the industry.
