Toshiba announces industry’s first dual camera module enabling simultaneous output of images and depth data


TCM9518MD camera moduleToshiba today launched the industry’s first dual camera module for smartphones, tablets and mobile devices. TCM9518MD incorporates twin 1/4 inch optical format 5-megapixel CMOS camera modules (5 megapixels x 2 arrays) and simultaneously outputs recorded images and depth data. Images captured with the module can subsequently be manipulated to change the depth of field and point of focus. The companion LSI generates 13-megapixel images by upscaling images taken by the twin 5-megapixel cameras, realizing a lower module height than that of conventional 13-megapixel camera modules.

The dedicated companion LSI of the TCM9518MD measures and appends depth data to objects in the image. These data can be used for a wide variety of applications, including focus and defocus, and even to extract and erase objects from the picture. Used in combination with customers’ applications, the module supports the creation of new functions. The TCM9518MD brings high resolution and computational camera functionalities to the CMOS image sensor market for smartphones, tablets and mobile devices. Samples will be available by January 2014, with mass production scheduled for April 2014.

Key Features of TCM9518MD
1. Simultaneous Output of Depth Data (Depth Map) and Deep Focus Image
The TCM9518MD’s twin cameras and dedicate companion LSI simultaneously deliver deep focus images in which foreground and background and all points in between are in focus, with depth data on each object in the image. This supports creation of new applications for smartphone, tablets and mobile devices, including refocus, defocus and extraction of any objects of the images, and gesture operation.

2. Output of 13-Megapixel Image
The companion LSI generates 13-megapixel photographs by upscaling images captured by the twin 5-megapixel cameras. This will contribute to downsizing of mobile devices.

3.Digital Focus Function
Most of auto focus camera modules for smartphones deploy a mechanical focus structure, moving the lens with motors like VCM3. It can take time to focus and also result shutter lag. TCM9518MD offers a non-mechanical digital focus function without mechanical structure, allowing high speed focus by calculating the depth to any objects4. It also realizes a lower module height.
