Socionext enters production with upgrade Camera Front Engine
The MB86S29 is the latest Milbeaut Image Processor product from Socionext and is designed primarily for smartphones. By accommodating new functionalities of the latest image sensors, the MB86S29 lets module makers implement these functions without replacing their application processors.
Smartphones and other mobile devices are frequently configured with application processors (AP) equipped with built-in image signal processor (ISP) functionalities. These APs can directly process output from image sensors, and help reduce the footprint and cost of camera modules. The MB86S29 supports this trend as a "Camera Front Engine" that replaces conventional ISPs. Connected in between an image sensor and an AP, it is specifically configured for Bayer data processing, so users can configure their APs with the same interface directory connected to image sensors, and to make full use of phase detect auto focus (AF) or high dynamic range (HDR).
The MB86S29 has four lanes each of 2.1 Gbps MIPI Rx / Tx. It can process 16M pixel images at 30 frame per second (fps). It is also applicable for noise reduction, shading correction, and 3A (AE / AF / AWB) detection. It is available in the smallest package of any member of the Milbeaut series, at 4 x 4mm.

Since its first release in 2000, the Milbeaut series of image processors has established a track record in applications from digital SLR cameras for ‘prosumers’ to commodities such as smartphones, or industrial equipment such as security cameras.
The MB86S29 has been designed to utilize "Hybrid AF", which combines the accuracy of contrast AF and the speed of phase detect AF, enabling maximum 4x faster AF, in comparison with the previous Milbeaut products.
The MB86S29 also supports Sensor HDR. Conventional HDR imaging, which generates a picture from multiple frames taken with different exposures, has disadvantages, such as images blurs caused by the difference between the frames, and time needed to take those multiple frames. The MB86S29 can process data with different exposure settings within one image so it can process the HDR images with higher visibility in 16M pixel, at the speed of 30 fps.
As a part aimed at the smartphone market, pricing is quoted at the high-volume point; $3.00 (5million).
