We propose a spectral response simulation method that calculates camera system output images based on image sensor spectral response (Quantum Efficiency: QE). This simulation realizes the pre-verification of the impact on SNR and color reproduction, enabling feedback for the design process. Optimizing the spectral characteristics of an image sensor requires considering the camera’s lens characteristics, IR cut filter characteristics, and the Color Correction Matrix (CCM), all of which are variables determined by image sensor's users. Therefore, even if the QE is improved, the final SNR improvement of the camera may be diminished depending on the system's spectral response. Conceivably, color reproduction may deteriorate. This simulation quantitatively verifies the extent to which improvements in QE characteristics contribute to the overall performance of the camera, providing a design foundation for optimizing both the camera and the image sensor. Moving forward, we will collaborate with researchers from industry and academia to examine the optical characteristics of image sensors from the perspective of system optimization. |
