Brightness obviously affects the pixel value of an image sensor. Image identification from a traditional sensor may generate a bias and surveillant misunderstandings because of weather. The proposed intelligent image sensor integrates an optoelectronic converting circuit and an embedded system and can convert the brightness to an analog voltage. From the voltage value, it can establish a contrast list to show the relationship of the analog voltage and image pixel values. Using the list and applying the linear interpolation method, it can eliminate the effect of the brightness and raise the identification rate. To improve the deficiency of conventional residence surveillance systems in real-time, multipoint, dispersed surveillance, the research proposed an integrated grid technology-based intelligent image surveillance system design.
