A system of automatic optimization of image quality of an image sensor includes an image learning data generation unit generating an image tuning knowledge database, which includes pairs of a plurality of sets of values of a plurality of parameters and a plurality of sets of image quality evaluation scores for a plurality of image quality evaluation items for evaluating a quality of each of a plurality of images generated by the image sensor, using an image tuning database sampling module, an image signal processor modeling unit generating a machine learning model, for each image, for automatically optimizing the quality of each image, and an image sensor image quality optimization unit automatically controlling values of some of the plurality of parameters based on a user's image quality selection and the machine learning model. The image quality evaluation scores are produced by a distributed camera simulation system including servers.

System and platform for automatic optimization of image quality of image sensor and operating method thereof

An image sensor includes a pixel array including first to third pixel groups, including first to third color pixels having first to third colors and outputting first to third pixel signal for the first to third colors, and an image signal processor receiving the first to third pixel signals, wherein the image signal processor, when the first pixel signal is a bad pixel signal, performs bad pixel correction on the first pixel signal based on the second pixel signal and the third pixel signal and generates a remosaiced pixel signal for the first through third colors by remosaicing the second and third pixel signals based on each other, and the corrected pixel signal and the remosaiced pixel signal represent information in which the first through third color pixels are rearranged in a second pattern having a higher frequency than a frequency of a first pattern.
