The purpose of this study is to clarify the relation between the discharge energy and the luminance strength at ignition plugs. The discharge phenomena were taken using CCD camera and recorded on video tape. The image data obtained here were analyzed through the image processing, which was able to extract the luminance strength information, so called RGB-value. The discharge energy increased linearly with the pressure in combustion chamber. It was found that an increase in the discharge energy induces the higher luminance of B-value. In other words, the color of spark at the higher pressure in combustion chamber becomes paler with an increase in the discharge energy.
