| Zusammenfassung: | An image processing apparatus includes a signal input unit to which an analog image signal is inputted, a first conversion unit for converting the analog image signal into a first digital image signal, a calculating unit for calculating a gray scale mean for an image by analyzing a brightness signal of the first digital image signal , and at least one second conversion unit for converting a portion of the analog image signal into a second digital image signal based on the gray scale mean. A combining unit may be provided for combining the first digital image signal and the second digital image signal based on the gray scale mean. Accordingly, an improved gray scale representation signal can be provided by performing an adaptive process to convert an analog image signal into a digital image, based on gray scales of the analog image signal. |
