The present invention provides an interactive display screen integrated with a video camera optimized to capture the user, the user's correct gaze, and information inputted on or through the interactive display screen. A presenter writes or draws information on the display screen while facing an audience. The display screen displays digital photos or other multimedia objects that a user can annotate or otherwise manipulate. Meanwhile, the device captures the displayed multimedia information and combines it with a video stream captured from the video camera. No extraneous video production equipment or technical expertise is required to operate while providing a compact and easily transportable system.

An image processing device according to the present technology includes: a correction unit that obtains a plurality of blur-corrected images by performing blur correction processing on an input image regarding a focus blur that occurs in a projection image by an image projection device, by using a filter coefficient for blur correction corresponding to each of a plurality of blur characteristics, the filter each being obtained on the basis of the plurality of blur characteristics; and an image output unit that individually outputs the plurality of blur-corrected images obtained by the correction unit.

A display system which controls a display of display content, includes: a processor; and a memory having stored thereon instructions executable by the processor. The instructions includes: performing image correction involving a change in a display position of the display content based on image correction data stored in advance; detecting an attitude change amount of a moving body; calculating, after the image correction is performed, a vibration correction amount of the display position of the display content based on the attitude change amount of the moving body and an image correction error of the image correction caused by vibration correction processing of correcting a display deviation caused by an attitude variation of the moving body; and controlling the display position of the display content based on the vibration correction amount.

Projection control method, electronic device, and storage medium are provided. The projection control method includes obtaining a first depth data corresponding to a reference object; obtaining a second depth data corresponding to a remote object; determining a first scaling ratio corresponding to the remote object according to the first depth data and the second depth data; and performing a holographic projection on the remote object according to the first scaling ratio and the second depth data, to obtain a first projection image.

A projection system and method for depth-based projection of image-based content is provided. The projection system receives a sequence of image frames to be projected on a physical surface of a three-dimensional (3D) structure. The projection system controls a depth sensor to acquire depth data associated with the physical surface and feeds a first input including the acquired depth data and a first image frame of the received sequence of image frames to a neural network-based model. The projection system further receives a set of geometric correction values as a first output of the neural network-based model for the fed first input and modifies the first image frame based on the received set of geometric correction values. The projection system further controls the illumination circuitry to project the modified first image frame onto the physical surface.

A focus adjustment method, adapted for a projection system is provided. The projection system includes a projection target and a projection device having a range-finding array element and a processor. A plurality of range-finding elements in the range-finding array element define a plurality of measurement mesh points. The focus adjustment method includes the following. A plurality of ranging regions in the measurement mesh points are defined, and each ranging region includes more than one measurement mesh point. All the range-finding elements in the ranging regions perform a ranging measurement to generate a plurality of original ranging values. An averaging calculation is performed on the original ranging values corresponding to each ranging region to generate a plurality of average region ranging values. Whether the average region ranging values are within a preset range is determined to generate an optimal ranging value which is used to adjust a lens focus.
