IMAGE PROCESSING DEVICE |
| 摘要 |
According to one embodiment, an image processing device includes a line memory that stores an input image by a plurality of rows; a defect correcting circuit that performs defect correction on the input image based on image data stored in the line memory; a binning circuit that generates a low pass image having a lower spatial frequency than the input image by binning the input image subjected to the defect correction; a frame buffer that stores the low pass image; a filter that generates a high pass image having a higher spatial frequency than the low pass image by filtering the input image subjected to the defect correction; and a mixing circuit that mixes the low pass image with the high pass image. |

1. An image processing device comprising:
a line memory that stores an input image by a plurality of rows; a binning circuit that generates a low pass image having a lower spatial frequency than the input image by binning the input image; a frame buffer that stores the low pass image; a filter that generates a high pass image having a higher spatial frequency than the low pass image by filtering the input image stored in the line memory; a mixing circuit that mixes the low pass image with the high pass image; and a sequencer that controls use of the low pass image in the mixing circuit based on correlation between the input images. |
