摘要

Visibility of a description on a description field hidden by a presenter is to be ensured while maintaining a positional relationship between the presenter and the description on the description field.The moving image data obtained by imaging a state where the presenter is giving the description onto the description field is processed to determine the description portion. Display data for displaying each of portions determined to be the description portion as a description is generated and superimposed on moving image data. For example, a difference value for each of pixels between a current frame image and a reference frame image is extracted, a group including a series of consecutive pixels having a difference value being a threshold or more is grasped and then, whether or not the group is a description portion is determined for each of the groups.

說明書

  • obtains the stationary time evaluation value on the basis of a difference value between the current frame image and a preceding frame image among the plurality of past frames, for pixels included in the group.
  • (4) The image processing apparatus according to any of (1) to (3),
    • in which the description superimposition processing unit performs processing for enhancing visibility of description when superimposing the display data over the moving image data.
  • (5) The image processing apparatus according to (4),
    • in which the description superimposition processing unit first performs processing of reducing resolution of the moving image data and thereafter superimposes the display data over the moving image data.
  • (6) The image processing apparatus according to (4) or (5),
    • in which the description superimposition processing unit first processes the display data so that each of portions determined to be the description portion is bordered and displayed, and thereafter superimposes the display data over the moving image data.
  • (7) The image processing apparatus according to any of (4) to (6),
