In-train information display apparatus, in-train information display system, and advertisement display result determining method

An in-train information display system comprising:

• a plurality of display apparatuses configured to display, to a passenger, video of advertisement content transmitted from an advertisement-content transmitting apparatus set on a ground side, wherein each display apparatus is located in a car of a train that includes a plurality of cars;
• and
• an advertisement-content delivering apparatus configured to store, in advance, the video of advertisement content data used in displaying the video of advertisement content and deliver a part or all of the stored video of advertisement content data to each display apparatus of the plurality of display apparatuses according to a schedule determined in advance, wherein
• each display apparatus includes:
• a display configured to display the video of advertisement content;
• a camera configured to photograph a video screen that displays the video of advertisement content on the display;
• a processor configured to calculate color-related information, which is information concerning a color for each pixel of the video screen, based on an image of the video screen photographed by the camera and determine, based on the calculated color-related information and reference information for display result determination, which is information concerning a color of the video of advertisement content normally displayed on the display, whether the display of the video of advertisement content has been normally performed, and
• a transmitter configured to transmit a result of the determination to the advertisement-content delivering apparatus,
• wherein the display inserts, halfway in reproduction of the advertisement content, a video for a short time unrecognizable by the passenger for display state check used in a determining operation for a display result as a checking-video,
• wherein the processor performs the determination using a photographing result of the checking-video, and
• wherein the advertisement-content delivering apparatus includes a display-achievement totalizing unit configured to (i) collect determination results received from the display apparatus of each car of the train and (i) totalize display achievements of the video of advertisement contents of each car of the plurality of cars of the train.

An advertisement display result determining method for determining a display result of video of advertisement content in an in-train information display apparatus that displays, to a passenger, the video of advertisement content delivered from an advertisement-content delivering apparatus, the advertisement display result determining method comprising:

• a step of photographing, with a camera, a video screen for the video of advertisement content, which is displayed on the display and actually seen from the passenger;
• a color-related information calculating step of calculating, by a processor, color-related information, which is information concerning a color for each pixel of the video screen, based on the photographed image of the video screen;
• and
• a display-result determining step of determining, by the processor, based on the calculated color-related information and reference information for display result determination, which is information concerning a color of the video of advertisement content normally displayed on the display, whether the display of the video of advertisement content has been normally performed;
• and
• a transmitting step of transmitting, by a transmitter, a result of the determination to the advertisement-content delivering apparatus, wherein said advertisement-content delivering apparatus collects determination results of a plurality of display apparatuses in respective cars of the train and totalizes the results, wherein
• the display inserts, halfway in reproduction of the advertisement content, a video for a short time unrecognizable by the passenger for display state check used in a determining operation for a display result as a checking-video, and
• the processor performs the determination using a photographing result of the checking-video.
