Abstract

The embodiment of the invention discloses a noise reduction method, a circuit system, electronic equipment and a computer readable storage medium, and the method comprises the steps: splitting a frame of at least continuous integration into a plurality of subframes which can be segmented for integration, wherein each subframe has respective time domain delay; enabling each time domain delay to generate a respective phase difference in a frequency domain, and fusing or superposing a plurality of subframes which can be subjected to segmented integration under the condition of the respective phase difference; and outputting a new sub-frame formed after fusion or superposition. And the frequency domain transfer function of the noise is changed through the phase difference, so that the noise signal is suppressed. And the noise on the image is greatly reduced, so that the finally output imaging quality is relatively high.

Description

technical field [0001] The present application relates to the field of circuit noise reduction, in particular to a noise reduction method, a circuit system, electronic equipment, and a computer-readable storage medium. Background technique [0002] In the prior art, noise reduction is usually performed based on the infrared image sensor chip of the microbolometer, but the low-frequency noise (flicker noise) of the front-end microbolometer is large, resulting in the equivalent temperature difference of the infrared image sensor noise (NETD) is large, which affects the signal-to-noise ratio and the technical problems of poor imaging quality. Contents of the invention [0003] In view of the above-mentioned technical problems in the prior art, the embodiment of the present application proposes a noise reduction method, a circuit system, an electronic device and a computer-readable storage medium to solve the problem that the equivalent temperature difference (NETD) is large, ...
