Description

Advertising machine and its operation method

The present invention relates to an advertising machine and a method of operating the same, and more particularly to an advertising machine for capturing and displaying an effective picture of a source image and a method of operating the same.

There are three common multimedia image display ratios, which are traditional 4:3 (ie 1.33:1), 16:9 (ie 1.78:1) for high-definition widescreen, and 2.39 commonly used in the film industry. :1, wherein the three specifications have different aspect ratios and sizes, and are also the standard ratios specified by the digital compression format.

However, when the multimedia image is input to a display device having a display specification different from the multimedia image, the display device takes corresponding compensation measures for displaying multimedia images of different specifications, and the most common two kinds of picture compensation effects are black edges. Compensation and extension compensation.

In the black side compensation part, it can be subdivided into upper and lower black side compensation, left and right black side compensation, and window type black edge compensation. Among them, the upper and lower black edges usually appear when the multimedia image used by the wide screen or the film industry is converted into a conventional size; and the left and right black edges are usually seen when the conventional size is converted into other sizes (usually a wide screen); the window black On the other hand, the multimedia image itself has upper and lower black edges or left and right black edges, and then the window type black frame appears when the left and right or the upper and lower black edges are compensated by the size conversion. This kind of compensation method can display the correct proportion of multimedia images on the multimedia image, but the appearance of the black border also sacrifices the beauty when viewed.

In addition, the portion of the stretch compensation is simpler than the black edge compensation. The display device usually compensates for the horizontal or vertical ratio of the multimedia image by extending the aspect ratio of the multimedia image left and right or up and down. The insufficient part, while causing distortion of the multimedia image.

Similarly, although the advertising machines currently used in the market to play multimedia images containing text, pictures or animations have been moving towards high image quality, networking and multimedia, there are still the above-mentioned compensation practices. The shortcomings. That is to say, the multimedia image creation content input to the conventional advertisement machine still needs to match the size ratio of the display screen of the advertisement machine to perform the most appropriate display.

Therefore, since the conventional advertisement machine displays the source image input to the advertisement machine, no special capture mode is performed internally, and the size of the source image and the display screen of the advertisement machine are not different from each other. Matching (for example, the pixel resolution of the source image is 1366×768, and the pixel resolution of the display screen of the advertising machine is 1366×256), so the display screen of the advertising machine can only display the uppermost part of the source image, but cannot be displayed. The rest of the source image. Therefore, it is necessary to seek a solution.

Accordingly, it is an object of the present invention to provide an advertising machine that allows any source image to be captured by the advertising machine and display its effective picture.

Therefore, the advertising machine of the present invention is adapted to capture an effective picture portion of a source image and display the effective picture portion of the source image, wherein the source image is a first number of horizontal direction pixels and a second The number consists of pixels in the vertical direction. The advertising machine includes a control unit and a display unit.

The control unit is configured to extract the effective picture portion from the source image, and output the effective picture portion, wherein an effective picture origin of the effective picture portion is in a vertical direction with respect to a source image of the source image Point, offset by at least one pixel.

The display unit is configured to display the effective picture portion.
