Calibration Step for use in Connection with Method and System for Creating Wide-Screen Picture-Dominance Effect in a Conventional Motion-Picture Theater
20210227172 · 2021-07-22 ·

A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.

MOVING VIDEO TAGS

A method causes a display device to display a video depicting an item in a scene and a tag in a first position on a first frame of the video. The tag is associated with the item depicted in the video, and the tag includes text information associated with the item depicted in the video. The method causes the video display to display the tag in a second position on a second frame of the video and causes the video display to display the tag in intermediate positions between the first and second positions during frames between the first and second frames of the video.

20210287349 · 2021-09-16 ·

An information processing apparatus that functions as a non-limiting example image processing apparatus includes a processor. When an original image drawn with horizontally-long first pixels is to be drawn by square second pixels, the processor generates two intermediate image data in each of which the number of second pixels is 1.2 times the number of first pixels of the original image data, by generating a second area formed with six (6) second pixels arranged in a horizontal direction for each of first areas that are formed dividing the original image by every five (5) first pixels arranged in the horizontal direction, and outputs the two intermediate image data to a display control device. The display control device generates output image data by synthesizing the two intermediate image data, and outputs the generated output image data to a display. The output image data is generated in each of the second areas with colors that include colors of the second pixels at both ends, which are in agreement with colors of the first pixels at both ends in each corresponding first area and colors of the second pixels other than the both ends, each of which is generated based on colors of adjacent two first pixels in corresponding first area.

Systems and methods for asymmetric image splitter with line mark memory

Described herein are systems and methods that provide for implement an asymmetric image splitter engine that may reduce the memory requirements. In one or more embodiments, a method may comprise receiving a multi-streaming video comprising super-frame video images, where each super-frame video images includes a first video image and a second video image, and where the height of the first video image is higher than the second video image. The vertical asymmetry of the second video image may be adjusted to same height as the first video image by adding padding to the second video image. An asymmetric image splitter engine may be utilized to split the super-frame video images into two separate video images. By marking each line of the second video image, it may be determined which lines are padded and discarded, and which lines are data to be displayed using a line mark memory.

Dynamically Controlled Aspect Ratios for Communication Session Video Streams

The disclosed techniques improve user engagement and promote efficient use of computing resources by providing dynamically controlled aspect ratios for communication session renderings based on a physical orientation of a device. In some configurations, a system can select a first aspect ratio for individual video streams of a communication session when a device is in a first orientation, e.g., a portrait orientation. In addition, the system can select a second aspect ratio for the individual video streams when the device is in a second orientation, e.g., a landscape orientation. In some configurations, the first aspect ratio can be greater than the second aspect ratio, or the aspect ratios can be selected based on a target aspect ratio, which can be adjusted over time. By dynamically selecting an aspect ratio for individual stream renderings, screen space of a device can be optimized while the device is held in various physical orientations.
