FIELD: devices for reading, recording and reproducing images, and method for correcting chromatic aberrations. ^ SUBSTANCE: processing of correction is performed with consideration of diaphragm aperture size and object image height in image reading lens. The output signal of the camera signal processing circuit (4) by means of switch (5) is sent to block (6) for correction of chromatic aberration. Value of aperture of diaphragm (31) in lens (1) for reading image, and coordinates of pixel, relatively to which correction processing is performed, from the block (6) for correction of chromatic aberration is sent to block (10) for computation of transformation ratio. The length of focal distance of approach or withdrawal of lens (1) for reading image and camera trembling correction vector are sent to block (10) for computing transformation ratio, then transformation ratio is produced for each color to be dispatched to chromatic aberration correction block (6), where the signal, corrected in block (6) for chromatic aberration correction is compressed in data compression circuit (15) for transmission to record carrier in device (17) for recording and reproduction and unpacked in data unpacking circuit (18) for transmission to switch (5). ^ EFFECT: increased quality of image, such as color diffusiveness. ^ 6 cl, 10 dwg |
