Abstract: A system for sensing and notifying material leakage includes a material leakage sensor provided as plural ones within a specific facility and configured to sense whether a material including a liquid or a gas leaks to the outside of a joint portion or an opening/closing portion of the equipment located inside or outside of the specific facility; and a controller configured to receive sensing information sensed by the material leakage sensor and transmit a material leakage notification to a security company device through a wireless communication module based on the sensing information. The security company device is a device of a security company in charge of security or guard for the specific facility.

Abstract: A method of blurred drawing processing for three-dimensional computer image processing and a computer readable program product storing a program and video game system for the same are provided which display a virtual three-dimensional space on a screen having the effect of a depth of field free from an unnatural feeling without increasing the load of the blurred drawing processing. That is, the effect is achieved without increasing the number of steps of blurring degree given in the depth direction of the virtual three-dimensional space. The invention converts a three-dimensional image to a two-dimensional image, and acquires depth data showing a depth position in the virtual three-dimensional space of the two-dimensional image. The invention also repeatedly performs blurring processing for blurring the two-dimensional image at the deeper side from a threshold value for each of a plurality of threshold values set in steps in the depth direction of the virtual three-dimensional space.
