Recent progress in attaining higher pixel counts and higher frame rates has lead to cameras with clearer, smoother motion video. On the other hand, such larger pixel counts has necessitated the smaller pixels and higher frame rates has shortened the time during which the individual pixels are irradiated with the incident light. These results in a reduction in the charge (electric signal) generated by the light and a decrease in sensitivity of the imaging device. With the aim of providing a radical solution to this problem, STRL has been researching a high-sensitivity imaging device based on a photoconductive film capable of multiplying the original charges generated by the incident light by many times simply with a low applied voltage (Figure).
