DR1152


Digital Image Processor for Single Sensor Cameras with Improved Dual Aperture



Introduction

The DR1152 is a special SoC that generates depth map with a single camera using Dual Aperture sensor technology, without an additional component for IR (infrared) emission. It can work with a 4-color image sensor or a 3-color sensor.
The DR1152 includes the ARM Cortex-M3 core, up to 128 KB of on-chip SRAM, an IPSS (Image Processing Subsystem) composed with DMP (Depth Map Processing), JPEG and ISP, a state configuration timer-subsystem, three SPI supports, two MIPI interfaces, a High-speed USB controller, an external memory controller and multiple digital and analog peripherals.

TECHNOLOGY

4-color Sensor

The DR1152 is unique in that it does not require an IR emitter. It obtains IR and RGB information from the ambient scene in a "passive" way, from a 4-color sensor. This leads to a more efficient, smaller and lower cost design for depth processing applications. Another benefit to this technology is that it will work for out-door activities where an IR emitter is ineffective due to the background IR that is present.

The SoC can also support 3-color sensors.


Dual Aperture takes focused IR and blurry RGB

The amounts of RGB and IR are controlled through the filters in the lens barrel.
Relative distance information is calculated by comparing the focused IR and the blurred RGB images, with convolution by the PSF matrix.
