Focus Control

This section explains the focus control features, including various autofocus modes and parameters, as well as manual focus.

Autofocus Modes

VirtualLens2 provides three autofocus modes:

Point AF

  1. VirtualLens2
  2. Image Control
  3. Focus Control
  4. AF Mode
  5. Point AF

In this mode, the focus adjusts to the point on the preview screen where the cursor is located. You can move this cursor by touching the preview screen with the index finger of the hand without the camera.

Face AF

  1. VirtualLens2
  2. Image Control
  3. Focus Control
  4. AF Mode
  5. Face AF

Face AF detects and focuses on the avatar’s face or eyes in the current image. If there are multiple faces in the frame, you can select which face to focus on by touching the preview screen with your index finger.

Selfie AF

  1. VirtualLens2
  2. Image Control
  3. Focus Control
  4. AF Mode
  5. Selfie AF

Selfie AF focuses on the eyes of the person taking the photo. It is a lightweight and stable option compared to Face AF, making it ideal for use when there is no need to focus on other players.

Autofocus Parameters

Face Detection Switching Speed

  1. VirtualLens2
  2. Image Control
  3. Focus Control
  4. Tracking Speed

When using Face AF, if the detection of the tracked face fails, the system will attempt to switch focus to a nearby face from the last detected point. This parameter controls the speed at which the system expands the search range to find a new tracking target.

Increasing the speed reduces the time during which there is no focus on any subject in situations with frequent changes in subjects. However, it may lead to unintentional changes in focus to different individuals if the face detection is unstable. Conversely, decreasing the speed ensures stable focus even with unstable face detection, but it takes more time for the system to switch to a new subject automatically.

Focus Adjustment Speed

  1. VirtualLens2
  2. Image Control
  3. Focus Control
  4. Focusing Speed

This parameter adjusts the speed at which the point where the autofocus sets the focus moves. Slowing down this speed results in a gradual change in distance to the focus plane over time.

Manual Focus

  1. VirtualLens2
  2. Image Control
  3. Manual Focusing

For manual focus, set the distance to the focal plane. The adjustable range can be configured during setup, within the “Min Focus Distance” to “Max Focus Distance” range. When this parameter is set to 0%, autofocus is used.
