Sony Semiconductor Solutions claims its IMX828 1/1.7-type (9.28 mm diagonal) CMOS image sensor is the industry’s first such component with an integral MIPI A-PHY interface. Promising low power consumption for next-gen automotive cameras, the component features an eight-effective-megapixel resolution and boasts the industry’s highest level of high dynamic range (HDR) attributes.
IMX828 CMOS image sensor for automotive cameras with built-in MIPI A-PHY interface.
As per Sony, better HDR attributes enable exponential improvements to high-luminance object recognition, such as red LEDs. Also, the sensor integrates a low-power-consumption parking surveillance function to detect moving objects and reduce the risk of theft and vandalism.
To support high-bandwidth, low-latency, and reliable communications between the camera and ECU that automotive camera systems require, multiple high-speed transmission interface standards exist. To address the need for reliable communications, the IMX828 integrates a MIPI A-PHY interface directly within the image sensor. It also integrates the company’s proprietary error handling circuit that makes it highly resistant to errors triggered by external noise when transmitting data. As a result, the component offers several advantages to OEM and Tier 1 partners that include:
- Lower costs due to eliminating the need for an external serializer.
- Compact board size and lower heat generation.
- Reduced camera module power consumption.
- Higher resistance to errors due to external noise.
