Sports Action Camera

What else would you need when you have a sports action camera to record every moment of your journey?

When the latest multi-functional sports action cameras hit the market a while ago, they were not only shaking grounds for the conventional DV makers, but leaving many consumers wondering whether they should include these handy devices into their next travel shopping list. These small and easy-to-operate video recording devices can come with powerful waterproofing protection, and can be easily attached to helmets or surfboards to record adventurous moments. Some biker or scooter riders also use them as “dashcam” on a day-to-day basis because they are designed to tolerate tough outdoor conditions and are effortless to carry.

Speaking of performance, there are two essential must-haves for their sensors - high frame rate and low power consumption rate, along with other add-ons such as high resolution and enhanced light sensitivity that determines the overall quality of the video footage taken. By satisfying all these critical factors, you have converged to a set of low-power consuming sensors that provide excellent image clarity even under speedy movement and low light environment – exactly what PixArt has to offer.

PixArt understands how demanding outdoor conditions can get. The sensors from PixArt's PrimeSensor™ series are designed with motion detection and low-light sensitivity features to maintain good video quality under speedy movement or unfavorable ambient lighting of as low as 0.1 lux. These powerful sensors designed for sports action camera applications have high framerate of up to 60fps and power consumption of as low as 77mW. They also come with multi-sensor synchronization, on-chip sign-shot HDR combination and 4-lane MIPI interface to optimize compatibility and flexibility for future implementations.

Panoramic Cameras

It is not hard to understand why the popularity of panoramic cameras continued to rise in large-area surveillance in recent years. Instead of purchasing and installing numerous cameras, the emergence of 180-degree and 360-degree panoramic cameras offers a cost effective solution by delivering wide-angled security coverage through one single camera.

There are two major types of technologies behind the panoramic technology – single-sensor cameras and multi-sensors cameras. Single-sensor cameras are sometimes known as the fisheye camera as they deliver convex images through fisheye or panomorphic lens for up to 180 degrees; however, it would require the use of a de-warping software to correct image distortion for better readability. They can come with good resolutions of up to 5MP, and serve general surveillance applications (including parking lots monitoring and detection of visitors flow) with good video quality. For more demanding monitoring requirements that request for highly detailed images, ultra-high video clarity and up to 360-degrees of coverage, there comes the multi-sensor cameras. A multi-sensor camera can capture multiple images simultaneously, then seamlessly stitch them together to form a massive 360-degree panoramic image.

The PrimeSensor™ series of PixArt offers sensors to support panoramic applications for both single-sensor and multi-sensor cameras. With in-built multi-sensor frame synchronization capability, good light sensitivity and low-power consumption, there is no doubt that these carefully designed products are ready to wow the market with its outstanding panoramic abilities. Taking cost optimization into further account, these panoramic-fitted sensors are designed with a perfect optimal aspect ratio of 1:1 – a perfect round-cropping size for you to make the most from the sensor perspective.

USB Cameras

A work-from-home worker or a business user who regularly holds video conference usually has higher expectation towards the image clarity and functionalities that his/her webcam can deliver. An external USB camera is there to give an instant boost in video quality.

Thanks to the widespread plug-and-play technology that allows most webcam devices to install their own drivers, users can enjoy better resolution, bigger lens, easily adjustable views, better light sensitivity as well as other add-on features such as pan, zoom, wide-angle lens and auto-focusing with very little fuss. Unlike a laptop's built-in webcam that may be constrained by the overall BOM cost and the mechanical lens/components fitting factors, USB cameras can use larger lenses or adopt a higher design standard because the users are willing to pay for the extra value.

Despite the fact that many of the CMOS image sensor products under PixArt's PrimeSensor™ product lines are suitable for high-end webcam applications, we have further designed two highly integrated USB SoC Sensors to facilitate the implementation of small-form-factor modules for our customers' USB camera application. These USB Video Class 2.0 SoC sensors come with built-in ISP, micro-controller, oscillator and 5-GPIO, and support Flash/EEPROM SPI interfaces for maximum compatibility and design convenience.
