Abstract: An image processing device according to the present disclosure includes: a movement detection unit that detects movement of a movable writing medium based on moving image data obtained by imaging the writing medium and a writer writing on the writing medium; and a writing portion detection unit that detects a writing portion on the writing medium, wherein the writing portion detection unit executes processing corresponding to the movement of the writing medium in a case where the movement of the writing medium is detected.

Abstract: There is provided an information processing device, a generation method, and a program that are capable of editing or reproducing a lecture-containing video in an appropriate form. The information processing device includes a generation unit configured to generate information for reproduction assistance, depending on importance levels each determined for one of predetermined sections generated by dividing data including a video and a sound of a lecture. The importance levels are determined on the basis of information associated with the lecture. The present technology can be applied to, for example, a lecture capture system used for imaging a lecture.

Abstract: Disclosed is an information processing apparatus including processing circuitry that sets a behavior detection parameter corresponding to a behavior of a subject based on input information corresponding to characteristics of a subject in an image, and detects a behavior of the subject based on the set behavior detection parameter and a posture of the subject in the image. The present disclosure can be applied to, for example, a lecture capturing system.

Abstract: An image processing apparatus includes: a moving object extraction unit configured to generate, regarding a moving object extraction target image, an extracted image obtained by extracting an image of a moving object in an area other than a mask area set as an area from which an image to be used for synthesis is not extracted; and an image synthesis unit configured to perform processing of synthesizing the extracted image with another image.

Abstract: An image processing device includes circuitry configured to detect states of a plurality of subjects in a first image and to set parameters corresponding to the detected states of the plurality of subjects. The circuitry is further configured to determine, on a basis of a combination of the parameters set for the plurality of subjects, an output range to obtain a second image.
