A light scattering particle counter that improves the signal-to-noise ratio by attenuating the high frequency noise component while suppressing the attenuation of the signal component by irradiating a sample fluid with a laser beam La to form a particle detection area, detecting a particle with a multi-channel light detecting element that receives scattered light Ls from a particle passing through the particle detection area, and with low pass filters having time constants &#x3c4;c, &#x3c4;m, &#x3c4;e that are set to depend on beam diameter of the laser beam La and flow velocity of the fluid which flows through each divided area, to count particles in the sample fluid.

Light scattering particle counter

A particle counting method that can count the number of the particles precisely. The method discriminates a wave pattern of the scattered light from a normal particle (subject of the counting) and a wave pattern of the light scattered by the agitation such as a floating particle, a radiation or changes in the intensity of the light. In one embodiment, a method for counting particles is disclosed which irradiates a light to a sample gas, detects a scattered light from a particle included in the sample gas by a photoelectric conversion device, counts the number of the particles of every particle size division by the output voltage wave pattern of the photoelectric conversion device, calculate a time difference (Ta&#x2212;T) from a point (T) being a peak of output voltage wave pattern and a point (Ta) being a falling detection threshold (A), when the time difference (Ta&#x2212;T) is beyond counting cancellation time (B), the output voltage wave pattern is not counted as a particle.

Particle counting method

An image generation system including: a drawing section which draws an object to generate image data; and an overdrive effect processing section which performs overdrive effect processing for the generated image data and generates image data to be output to a display section. The overdrive effect processing section performs the overdrive effect processing based on differential image data between image data generated in a Kth frame and image data generated in a Jth frame (K&#x3e;J).

Program, information storage medium, image generation system, and image generation method for generating an image for overdriving the display device
