PowerVR V2500 Imaging Processor from Imagination Gives Smartphones More Power

As smart mobile devices become part of the corporate infrastructure with BYOD initiatives, cloud computing and other integrations, the hardware within these devices has to provide professional grade solutions. This is especially the case when they are being used for videoconferencing. Imagnation, creator of processor solutions for graphics, video, display, embedded processing, multi-standard communications and connectivity, has introduced the PowerVR V2500, the first Series2 Raptor imaging processor core.

The V2500 is able to scale seamlessly to provide low-power products such as mobile devices and wearables with the performance they need for Ultra HD video, multi-megapixel photography and higher pixel depth sensors. The technology can be applied in embedded products for the automotive industry, medical imaging and professional cameras.

While the imaging processor of smartphones gets very little attention, the camera’s capability on the device is one of the biggest determining factors when consumers are making the choice to purchase one. During the Mobile World Congress in Barcelona, many companies have been highlighting the capability of their camera, including Sony, which has a 4K video capture capability on one of its smarthphones.

PowerVR V2500 imaging processor ISP core provides high performance at low power with advanced low-noise processing pipelines (1D and 2D, image enhancement, display and encoder) so it can deliver the best computational photography solution consuming only milliwatts of power.

The high configurability options supports all major CMOS sensors and can switch between multiple stereo cameras at once as well as being configured to sensor resolution, reducing area and power consumption.

The architecture is designed to support stereo, multi-cam, and vision array cameras for volumetric imaging in a small, single core solution.

All of these features are implemented using an algorithm that is able to correct aberrations to deliver high image quality by avoiding irregularities in the image such as artifacts, unnatural colors, moire and other unwanted sharpening kernels.

The PowerVR vision platform optimizes all of the processing elements from capture to display by offering every computational photography pipeline puzzle, which includes: the ISP (PowerVR V2500 and other Series2 Raptor cores), the video encoder and decoder (PowerVR Series5), the GPU (PowerVR Series6/Series6XE/Series6XT Rogue), and the CPU (MIPS Series5 Warrior).
