Image sensor integrates MIPI receiver

Micron Technology Inc. has designed a receiver interface into one of its new mobile imaging sensors, helping to advance 3G videophone calling.

The receiver, compliant with the MIPI standard, allows for the image signal processor (ISP) embedded in the sensor for the primary camera to be repurposed as the ISP engine for the secondary camera, reducing the second camera's cost. Secondary cameras are gaining popularity as a key design feature in today's handsets, allowing for 3G videophone calling within designated networks.

"As today's mobile phones continue down the path of becoming more feature-rich with new capabilities such as 3G videophone calling, interface standards such as MIPI are becoming more critical," said Sandor Barna, director of strategy and planning for Micron's imaging business unit. "We were first to announce an image sensor with a MIPI transceiver and we are continuing that tradition of technological leadership with the introduction of the MIPI receiver."

Claimed to be the first sensor to feature the MIPI receiver is the 0.25-inch, 3Mpixel complete camera SoC sensor (MT9T111). The MT9T111 sensor also features an industry-leading anti-shake capability, greatly reducing image blurring often found in camera phone pictures due to camera shake. General customer sampling for the sensor is currently underway, with mass production expected in Q4. Micron also plans to deploy the MIPI receiver interface in some of its future mobile phone sensor products.
