Kiosk and Digital Signage Camera: High-Resolution Imaging with Interactive Displays

Requirement Overview

Vadzo worked with a leading kiosk manufacturer looking for an off-the-shelf camera to be integrated into their kiosk platforms to enable video streaming and image capture to perform tasks such as facial recognition, document scanning, and so on. 

Challenges

Variable Depth of Field

• Traditional kiosk systems suffer from achieving focused images of the user due to a lack of visual clarity arising from the dynamic nature of the user in terms of how far they position themselves from the kiosk.

• Most cameras are equipped with fixed focus lenses that are not meant for such varying depth of field requirements.

• This limitation creates uncertainty in terms of the quality of the image captured and thus uncertainty in the outcome of facial recognition algorithms.

Quick Focusing to increase responsiveness

• The kiosk manufacturer was keen on achieving the focus state quickly to ensure quicker processing for each user and ensure seamless queue management.

• Most traditional autofocus algorithms have longer focus-setting cycles.

• Slow Focus Settling can result in low quality images of users' face or documents if the user changes position or document is moved.

• Capability to capture Higher Field of View.

• Users expect interactive kiosk systems and digital signage to offer flexibility to accommodate varying heights ranging from 4m to 7.2m.

• The kiosks are also expected to cater to individuals with disabilities, including those who use wheelchairs, ensuring accessibility for all.

The Solution

The Vadzo IMX258 Color 4K PDAF USB 3.0 Camera emerges as a game-changing solution for interactive kiosks and digital signage, offering advanced imaging capabilities tailored to meet the specific requirements of these systems.

High-Resolution Imaging

• The Vadzo IMX258 Camera supports resolutions of 720p, 1080p, 4K, and 13MP, delivering exceptional visual clarity and detail.

• With its high-resolution imaging capabilities, the camera enhances the quality of content displayed on interactive kiosks and digital signage, creating immersive and captivating experiences for users.

Phase Detection Autofocus (PDAF)

• The PDAF feature enables fast and accurate autofocus, ensuring that images remain sharp and clear even in dynamic environments.

• By eliminating the need for manual focusing adjustments, PDAF enhances the usability of interactive kiosks and digital signage, allowing for seamless interactions with users.

Region of Interest (ROI) Autofocus

• ROI Autofocus allows users to define specific areas of interest within the camera's field of view, ensuring that critical elements are always in focus.

• This feature is particularly useful for digital signage applications where selective focus is needed to highlight key messages or products.

UVC Compliant USB 3.0 Type-C Interface

• The USB 3.0 Type-C interface ensures high-speed data transfer and compatibility with a wide range of devices, including interactive kiosks and digital signage systems.

• This plug-and-play interface simplifies installation and integration, making it easy to incorporate the Vadzo IMX258 Camera into existing setups.
