Title:
移動物体ノイズ除去処理装置及び移動物体ノイズ除去処理プログラム
Document Type and Number:
Japanese Patent JP4878644
Kind Code:
B2
Abstract:
A moving object noise elimination processing device and a moving object noise elimination processing program are provided for making it possible to effectively eliminate a noise due to a moving object in front of a photographing object with a relatively simple method. A moving object noise elimination process involves first photographing an image every predetermined sampling interval Δt and the photographed images are stored in association with time (S10, S12). Next, with respect to the currently photographed image frame data and the previously photographed image frame data, each corresponding pixel brightness value is compared (S14, S16, S18). For each pixel, the one with a higher brightness value is then eliminated as a noise and that with lower brightness value is left (S20). The brightness value in each pixel of the image frame is updated with the left brightness value in each pixel and the updated one is output (S22, S24). Further, a moving object frequency is calculated from a ratio of the total number of data to the number of data with the eliminated brightness values and the calculated one is output (S26, S28).
