Video-signal processing apparatus, video-signal processing method, and video-signal processing system

A video-signal processing method comprising the steps of:

• receiving an input of a video signal including multiple images arranged in a time sequential manner, the video signal serving as a single content item;
• outputting a plurality of images generated on the basis of the multiple images, in a time-division manner, within output periods of the multiple images;
• receiving user inputs from one or more users for each of the multiple images upon display of each of the multiple images to the one or more users;
• and
• performing, by signal processing units, image quality adjustments on the multiple images in accordance with the user inputs, wherein
• the signal processing units include area specifying units configured to specify, within an area where the images are displayed, areas to be subjected to the image quality adjustments, and
• the signal processing units perform image quality adjustments only on images output to the areas specified by the area specifying units.

A non-transitory computer readable storage medium have executable instructions stored therein, which when executed by a processor in a video-signal processing apparatus causes the processor to execute a method comprising the steps of:

• outputting, in a time-sequential manner, a video signal constituting n images corresponding to input multiple images arranged in a time sequential manner;
• performing, by signal processing units, image quality adjustments individually on the n images;
• obtaining adjustment values of the image quality adjustments performed in the step of performing image quality adjustments, the adjustment values corresponding to user inputs from one or more users for each of the n images upon display of each of the n images to the one or more users;
• and
• outputting images that have been subjected to the image quality adjustments performed in the step of performing image quality adjustments, wherein
• the signal processing units include area specifying units configured to specify, within an area where the images are displayed, areas to be subjected to the image quality adjustments, and
• the signal processing units perform image quality adjustments only on images output to the areas specified by the area specifying units.

A video-signal processing system comprising:

• a video-signal processing apparatus;
• and
• one or more pairs of glasses,
• wherein the video-signal processing apparatus includes
• a video-signal input unit to which a video signal including multiple images arranged in a time sequential manner is input, the video signal serving as a single content item, and
• a time-division output unit configured to output a plurality of images generated on the basis of the multiple images, in a time-division manner, within output periods of the multiple images, and
• operation input units that receive inputs from one or more users for each of the multiple images upon display of each of the multiple images to the one or more users, and
• signal processing units configured to individually perform image quality adjustments on the multiple images in accordance with the user inputs, and
• wherein the one or more pairs of glasses include
• shutters, each of the shutters being switchable between a state in which light is transmitted and a state in which light is blocked, and
• shutter open/close control units, each of the shutter open/close control units being configured to open a corresponding one of the shutters in synchronization with a corresponding one of the plurality of images output from the time-division output unit in the video-signal processing apparatus, wherein
• the signal processing units include area specifying units configured to specify, within an area where the images are displayed, areas to be subjected to the image quality adjustments, and
• the signal processing units perform image quality adjustments only on images output to the areas specified by the area specifying units.
