Position (center coordinates) Coordinates on the screen from the top-left corner of the screen (in pixels)
Size Pixel size on the input image
Degree of confidence Confidence in the detection result (0 to 1000), a higher value indicates a higher confidence
Face Direction Estimation Yaw angle Positive to the right (in degrees)
Pitch angle Positive upwards (in degrees)
Roll angle Positive clockwise (in degrees)
Degree of confidence Confidence in the estimation result (0 to 1000), a higher value indicates a higher confidence
Gaze Estimation Yaw angle Positive to the right (in degrees)
Pitch angle Positive upwards (in degrees)
Blink Estimation Blink degree Output for both eyes (1 to 1000), a higher value indicates the eye is closer to being fully shut
Age Estimation Age 0 to 75 (75 includes higher ages)
Degree of confidence Confidence in the estimation result (0 to 1000), a higher value indicates a higher confidence
Gender Estimation Gender Male or female
Degree of confidence Confidence in the estimation result (0 to 1000), a higher value indicates a higher confidence
Expression Estimation Score for 5 expressions 0 to 100
The score will be output for each expression ("neutral", "happiness", "surprise", "anger" and "sadness").
The score indicates the likeliness of a face displaying the estimated expression, where a higher score indicates a higher likeliness of being that expression.
Expression degree (positive or negative) +100 to -100
A degree closer to +100 indicates a high degree of "happiness" while a degree closer to -100 indicates a high degree of "surprise", "anger" or "sadness".
Face Recognition Individual identification result Displays either the registered User ID, or "non-registered" for non-registered individuals
Maximum number of users: 100
Maximum number of data per use: 10
Registration is done with the Product.
Score Matching degree (0 to 1000)
The result of the user with the highest matching degree is output.
A degree closer to 1000 indicates a higher likeliness of being that user.
  • * Degrees of confidence are grain size 1. Angles are for when facing the camera.

Precautions for Safe Use

Observe the following precautions to prevent failure to operate and malfunctions, and to prevent adversely affecting the performance and function of the Product.

  • Store the Device at a temperature between -30 and +70°C and a humidity level below 90%.
  • Do not touch the board mounted parts with bare hands. Discharge any static electricity from the user before use.
  • Take proper measures against static electricity by using an antistatic wrist strap, etc. before handling the Product.
  • Make sure to properly ground the connector's earth terminal in order to prevent malfunction due to noise.
  • Do not use the Product in places where the surrounding temperature goes above the rating range.
  • Do not use the Product in a location where it would be subjected to direct sunlight.
  • Do not use the Product in a location subject to excessive inductive or power supply noise, such as in strong magnetic or electric fields.
  • Do not use the Product in a location where it would be subjected to strong UV light.
  • Do not use the Product in a location where it would be subjected to radiation.
  • Sufficiently evaluate the electrical characteristics of any connection to the Device.
  • Make sure to properly align the connectors when connecting them.
  • Avoid desorption of power supplied connectors as it will result in accidents.
  • Refer to the B5T-007001 Command Specifications document separately provided by OMRON for details on the interface specifications.
  • Never use benzene, paint thinner, or any other volatile cleaning solution, detergent, bleach or chemical washcloth for cleaning the Device.
  • Take in consideration heat dissipation from the Device when installing it in order to improve its long term reliability.
  • Install the Device sufficiently far away from any other surrounding charged parts.
  • Install the Device making sure not to obstruct the camera detection range.
  • Use transparent materials to cover and protect the front of the lens should it be in contact with hands or objects.
  • Remove the lens protective seal before use (B5T-007001-010).
  • Remove the lens protective cover before use (B5T-007001-020).
  • Do not touch the camera module.
  • The Product performs detection on images. As such, note that it may sometimes detect objects other than living bodies, such as photographs or posters.
  • Note that since the Product uses a camera for detection, successful detection may not be possible due to light orientation, brightness or exposure issues.
  • Make sure to reset the Product before using it again following a power interruption or failure.
  • Restart or reset the Device if data is received improperly.
  • Cutting or losing power to the Device while saving the Album on the flash ROM may destroy the Album data saved on it. As such, make sure to take a backup of the Album data on the Host device. Refer to the B5T-007001 Command Specifications document for details.
  • Do not use the USB and UART connection method simultaneously.
  • Do not remove the FFC connection between the main board and the camera board, and do not alter the configuration of the combination.
  • When using the USB connector, note that the bus power may not be properly powering the Device depending on the computer USB port used. In such case, use a device like a selfpowered hub with an AC adaptor.
