Note that, in the present technology, it is allowable to further include a description superimposition control unit that controls description superimposition processing unit not to superimpose the display data over the moving image data when a state where the face of the presenter is facing front is detected on the basis of the moving image data. In a case where the presenter stops one's hand and starts verbal presentation and commentary, presenter's expression and gestures would be more important information rather than the description, and the above would enable display of these without being disturbed by superimposed display of description.

Furthermore, in the present technology, it is allowable to further include, for example, an imaging unit that images a state where the presenter is presenting a description onto the description field, and an imaging signal processing unit that processes an imaging signal obtained by the imaging unit and obtains the moving image data. Furthermore, in the present technology, it is allowable to further include, for example, a transmission unit that transmits the moving image data obtained by the description superimposition processing unit to an external device.

According to the present technology, it is possible to ensure the visibility of the description on the description field hidden by the presenter while maintaining the positional relationship between the presenter and the description. Note that effects described here in the present specification are provided for purposes of exemplary illustration and are not intended to be limiting. Still other additional effects may also be contemplated.
