Acoustic signal corrector and acoustic signal correcting method

An image display method of displaying a list of images of appearing in video content data, comprising:

• performing an image extraction process of extracting representative images from a plurality of frames which constitute the video content data and outputting time stamp information indicative of time points at which the extracted representative images appear;
• and
• performing an image list display process of displaying a list of representative images, which appears in the video content data, on a two-dimensional display area by using the representative images extracted by the image extraction process, the two-dimensional display area includes a plurality of image display areas that are arranged in a matrix including a plurality of rows and a plurality of columns,
• wherein a plurality of time zones, which are obtained by dividing a time length of the video content data by the number of the plurality of columns, are allocated to the plurality of columns, respectively, and
• the image list display process displays, based on the time stamp information corresponding to each of the extracted representative images, the representative images, which belong to the time zone allocated to each column, on the image display areas of each column, by arranging the representative images in an order of time of appearance of the representative images.

A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of:

• performing an image extraction process of extracting representative images from a plurality of frames which constitute the video content data and outputting time stamp information indicative of time points at which the extracted representative images appear;
• and
• performing an image list display process of displaying a list of representative images, which appears in the video content data, on a two-dimensional display area by using the representative images extracted by the image extraction process, the two-dimensional display area includes a plurality of image display areas that are arranged in a matrix including a plurality of rows and a plurality of columns,
• wherein a plurality of time zones, which are obtained by dividing a time length of the video content data by the number of the plurality of columns, are allocated to the plurality of columns, respectively, and
• the image list display process displays, based on the time stamp information corresponding to each of the extracted representative images, the representative images, which belong to the time zone allocated to each column, on the image display areas of each column, by arranging the representative images in an order of time of appearance of the representative images.
