CMOS Area Image Sensor

CMOS area image sensors are integrated circuits (ICs) that convert light into an electronic signal.  They consist of a photodiode array and multiple CMOS transistors per pixel.

Toshiba has developed CMOS area image sensors to meet the need for high performance and small form factor.  Toshiba's CMOS area image sensors will open up new possibilities with their use of outstanding technologies such as high dynamic range (HDR) that delivers smooth and crisp video, color noise reduction (CNR) and backside illumination (BSI) that offers high sensitivity.  Additionally, these image sensors provide high image quality thanks to advanced CMOS sensor technologies such as micro-lens and photodiode optimizations.  Toshiba's CMOS area image sensors are available with a wide range of resolution from VGA to over 10 million pixels and with a pixel size from 1.12 µm to 5.6 µm, making them suitable for a wide range of applications such as smartphones, tablet PCs, surveillance cameras and automotive cameras.

CMOS Features Overview

  • 1.12 µm to 5.6 µm pixel size and VGA to over 10 million pixels
  • High Dynamic Range (HDR) and Color Noise Reduction (CNR)
  • High-sensitivity backside illumination (BSI) image sensors
  • Available in module, package and die forms.

Toshiba Launches 13 Megapixel Image Sensor with ‘Bright Mode’ High-Speed Video Technology

Toshiba have announced it will offer the T4K82, a 13-megapixel BSI1 CMOS image sensor that allows smartphones and tablets to record full HD video at 240 equivalent frames per second (fps) - the industry’s highest2 frame rate. Sample shipments are scheduled to start in March.

High-speed video recording generally results in underexposed images with short exposure times, making it difficult to increase the frame rate. Toshiba's T4K82 incorporates 'Bright Mode' technology that boosts image brightness by up to four times, realizing full HD video capture at 240 fps equivalent. As a result, the sensor allows smartphones and tablets to record high-quality, high-speed video, and to offer extended imaging functions including smooth slow motion playback and high-speed continuous shooting.

Toshiba Starts Sample Shipments of Dual Camera Module Enabling Simultaneous Output of Images and Depth Data

Toshiba have started sample shipments of a dual camera module for use in smartphones, tablets and other mobile devices. TCM9518MD is the industry's first dual camera module to incorporate twin 1/4 inch optical format 5-megapixel CMOS camera modules (5 megapixels x 2 arrays), able to simultaneously output recorded images and depth data.

Depth Map

A depth map contains the distance data between a camera and objects.  The depth map is output in values.  Toshiba's dual camera module product combined with a dedicated companion LSI simultaneously delivers deep focus images and depth data.  A deep focus image is an image in which foreground and background and all points in between are in focus.

Using the depth map output from the companion LSI, applications can get depth data on each object with simplified calculation.  The depth map can be used for a wide variety of new applications for devices having camera modules and a companion LSI, including refocus, defocus and extraction of any objects of the images, and gesture operation through video images.

HDR (High Dynamic Range)

High dynamic range (HDR) imaging is a feature for capturing images that have a wide contrast range between the lightest and darkest areas. It helps make such images more natural-looking by stretching the dynamic range. Toshiba has developed HDR function for image sensors that can correct high-contrast scenes to produce natural-looking images for both still and video capture. Toshiba's HDR function delivers a smooth and crisp video by reducing blur and false colors that are inherently produced as a result of HDR composition.

CNR (Colour Noise Reduction)

Colour noise reduction (CNR) is a feature for reducing colour noise that adversely affects the visibility of an image. Toshiba's CNR circuit incorporates a digital filter that compares images between consecutive frames to extract only colour noise artifacts.

It enhances image quality without compromising the sharpness of an image. Toshiba's CMOS image sensors with a CNR circuit offer smaller pixel pitch, higher image resolution and higher image visibility at low illuminance than those without a CNR circuit.

BSI (Backside Illumination)

A backside illumination (BSI) sensor is a type of image sensor designed to capture the incoming light with the photodiode layer on the backside of the device.

As smartphones and tablets become thinner, lighter and more sophisticated, semiconductor vendors are required to reduce the size and improve the resolution of CMOS image sensors.  However, reducing the pixel pitch of a CMOS image sensor causes a reduction in incident light, which in turn leads to a reduction in sensitivity.
BSI, which receives light at the backside, makes it possible to further reduce the pixel size without causing reductions in the amount of light captured and thus light sensitivity.
