Monitor for monitoring a panoramic image

A method of monitoring a generated panoramic image, the method comprising:

• a defining step defining a plurality of regions with a threshold value greater than a predetermined threshold value,
• wherein different threshold values are defined for each of the plurality of regions that constitute the generated panoramic image;
• a comparing step of sequentially detecting a difference of luminance level between each image region forming the generated panoramic image and a corresponding image region of another generated panoramic image taken prior to a first image along a same shooting direction and comparing the detected difference of luminance level with the predetermined threshold value for each image region, and exempting a plurality of the plurality of regions from comparison according to the defined threshold values to minimize workload and reduce frequency of drawing user's attention to apparent differences generated by R, G, B signals that cannot be visually detected;
• a shifting step for shifting the shooting direction sequentially in a horizontal and vertical direction from a coordinate (1, 1) to (i, j) to shoot an entire area with a set view angle u to obtain the plurality of regions;
• a compression step for compressing and coding the image signal;
• an adding step for adding position information and corresponding meta-data to the image signal;
• and
• a display step of causing predetermined information to be displayed on a display screen along with the generated panoramic image according to the result of the comparison in the comparing step.
