Abstract

The invention relates to a method and to an arrangement for the synchronization of the image recording of monochrome recordings and color recordings with photosensitive line sensors. A line-scanning pattern is generated by a programmable counter arrangement, wherein the timer measures the phase position of the line-scanning pattern, generated by the counter arrangement, with the aid of the computer and the programmable counter arrangement at the point in time of the impinging of a pulse of the incremental transmitter, wherein the timer compares these with a coordinated calculated or tabulated reference value, and wherein the timer employs the thus obtained phase difference in order to influence a counter, preconnected to the line counter CT2, in its count volume (FIGS. 1 and 2). The timer splits the measurement lines of the image recording device into two or more scanning lines if the integration time of the photosensitive lines within the measurement line results in an exposure higher than the operating limit of the sensors.
