World's smallest camera

 

OMNIVISION

OmniVision Technologies is a leading developer of advanced digital imaging solutions. The company produces high-quality still and video images for smartphones, surveillance cameras, and other devices ¹. 
OmniVision has recently adopted a new brand with a new look: OMNIVISION. The updated branding reflects its latest expansion in product offerings and capabilities.

 In addition to image sensors and related technologies, the organization now offers analog and touch & display solutions ².

OMNIVISION HISTORY

OmniVision Technologies was founded in 1995 by Aucera Technology ¹.

 Since then, the company has been at the leading edge of technology, developing and delivering advanced digital imaging, analog, and touch & display solutions for multiple applications across several industries ².

Some company milestones include:

- 1999: First Application-specific integrated circuit (ASIC)

- 2000: IPO

- 2005: Acquired CDM-Optics, a company founded to commercialize wavefront coding

- 2010: Acquires Aurora Systems and adds LCOS to its product line ¹.

 How OMNIVISION's OVM6948 Camera Cube Chip is Revolutionizing Medical Imaging

It is the world's smallest camera that is smaller. Than small drop of water.

MEDICAL IMAGING 

Medical imaging is a vital tool for diagnosing and treating various diseases and conditions. However, conventional endoscopes and cameras have limitations in terms of size, resolution, power consumption and cost. These factors can affect the quality of images, the comfort of patients and the efficiency of procedures.

 That's why OMNIVISION, a leading developer of advanced digital imaging solutions, has created the OVM6948 CameraCubeChip, a fully packaged, wafer-level camera module that measures only 0.65 mm x 0.65 mm, with a z-height of just 1.158 mm¹.

 This camera module is derived from an ultra small image sensor, the OV6948, winner of the Guinness World Record for "The Smallest Commercially Available Image Sensor*", with its size of 0.575 mm x 0.575 mm².

CAMERA CUBE CHIP

The OVM6948 Camera Cube Chip is ideal for disposable devices operating from the smallest part of the anatomy, such as guidewires, catheters and endoscopes with a diameter as small as 1.0 mm¹. 

With this camera's small size and high 200 x 200, or 40 KPixel backside-illuminated resolution, high quality images can be captured from within the body's narrowest blood vessels for neuro, ophthalmic, ENT, cardiac, spinal, urology, gynecology and arthroscopy procedures¹.

HIGH QUALITY IMAGE

The OVM6948 CameraCubeChip® is the only ultra small "chip on tip" camera with backside illumination, which provides excellent image quality and better low-light performance to help reduce LED heat, along with improved sensitivity. 

It offers a compact, high quality solution for disposable guidewires, catheters and endoscopes, which are experiencing growing demand because of their ability to reduce cross-contamination risks, downtime inefficiencies and costs associated with the repairs, preprocedural testing and sterilization of reusable endoscopes¹.

POWER CONSUMPTION

Benefiting from the sensor's low power consumption of a mere 25 mW², less heat is generated for better patient comfort and flexible procedure durations. Other key features of this camera module include a wide 120-degree field of view and an extended focus range of 3 mm to 30 mm².

 Its image array is capable of capturing 200 x 200 resolution images and video at up to 30 frames per second², and its analog output that can transmit over 4 meters with minimal noise².

The OVM6948 CameraCubeChip is not only suitable for medical applications, but also for other fields that require miniature cameras with high performance, such as dental equipment, security and surveillance, toys and games, wearable devices and IoT applications².

OMNIVISION's CameraCubeChip technology integrates image sensors, processor and lenses in a miniature wafer-level camera module that enables ultra-thin, compact devices with advanced imaging capability³. 

The company offers a range of CameraCubeChip products with different specifications and features to meet various customer needs.

DIFFERENCE BETWEEN IMAGE SENSOR AND ASIC

An **image sensor** is a device that captures light and converts it into an electrical signal. It is the core component of a digital camera and is responsible for capturing the image ¹. 

On the other hand, an **ASIC camera** is a camera that uses an **application-specific integrated circuit (ASIC)** to perform image processing tasks. 

An ASIC is a chip that is designed for a specific application and can perform complex functions at high speeds ².

These pictures defines that the camera quality is not more than android phone camera.

Conclusion:

In summary, an image sensor captures light and converts it into an electrical signal, while an ASIC camera uses an ASIC to perform image processing tasks.
