摘要：
A solid-state infrared image sensing device has an image pick-up pixel array having respective bolometers sequentially connected to a read-out circuit for producing an image carrying signal: However, the image carrying signal contains a fixed pattern noise due to the pattern of the bolometers: In order to produce a first reference signal representative of the standard magnitude of fixed pattern noise and a second reference signal representative of a deviation from the standard magnitude to the magnitude of fixed pattern noise at a selected image pick-up pixel, reference pixels are provided around the image pick-up pixel array.
