Abstract: There is provided an image archiving method for use with a writing target, comprising the steps of receiving a series of captured images of the writing target, detecting difference between first and second candidate received images separated by a predetermined period of time, where additive differences are indicative of writing and subtractive differences are indicative of erasure; upon detecting subtractive difference, temporarily retaining a last candidate image captured prior to the detection, and detecting whether the subtractive difference relative to the retained image exceeds a subtraction threshold amount; and if so, then storing the retained image.

Abstract: 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.

Abstract: [Object] There is provided a mechanism that makes it possible to efficiently specify an important region of a moving image including a dynamic content. [Solution] An information processor including a control unit that recognizes a motion of an operator with respect to an operation target in a moving image and specifies an important region of the operation target in the moving image on a basis of an operation position of the operator.

Abstract: Visibility of a writing content image of writing contents written on a writing surface can be enhanced. There is provided an image processing apparatus including processing circuitry. The processing circuitry is configured to modify one or more characteristics of a writing content image of writing contents written on a writing surface. The modification of the one or more characteristics of the writing content image is based on information related to the writing surface.

Abstract: It is possible for the viewer to readily and accurately reach a desired image/audio reproduction start position in reproduction. A time code is added to moving image data obtained by imaging a state in which a person who writes a description is explaining while writing a description in a description portion and audio data corresponding to the moving image data to record the data in a recording unit. The moving image data is processed to determine a written portion written in the description portion, and index image data is generated to display each portion determined as the written portion as an index description, and the index image data is recorded in the recording portion. To the index image data, a value of the time code corresponding to description time is added as a timestamp, in association with each pixel constituting the index description.
