Image processing device, image processing method and image processing system

An image processing device connected to a user terminal, comprising:

• a storage unit configured to store a three-dimensional image and a predetermined interest region in the three-dimensional image;
• and
• a processor configured to:
• receive a plurality of input signals according to operation of an input device of the user terminal, and
• sequentially generate a plurality of two-dimensional section images from the three-dimensional image and cause the two-dimensional section images to be displayed at the user terminal,
• wherein the processor is further configured to:
• calculate primary display control information including an input speed of the received input signals;
• calculate secondary display control information including a time interval based on the calculated primary display control information including the input speed, and
• cause the two-dimensional section images to be sequentially displayed at the user terminal based on the calculated secondary display control information including the time interval,
• wherein the processor is further configured to:
• determine that the interest region is included in a currently generated two-dimensional section image,
• determine a change flag which is a number of times the input speed falls below a first threshold value,
• when the interest region is included in the currently generated two-dimensional section image, when the input speed is greater than the threshold value and when the change flag is less than a second threshold value, increase the time interval by a predetermined amount from a first value to a second value, and
• wherein the currently generated two-dimensional section image is displayed at the user terminal based on the calculated secondary display control information including the increased time interval.
