PROBLEM TO BE SOLVED: To obtain required image data at a required time in response to a state at peak detection or the like or at substantial image reading. SOLUTION: Terminals Eno, Ene are both set to an L level and a synthesis output is selected, then image data DT resulting from the synthesis and incorporated to be one system are outputted. Only either of the terminals Eno, Ene is set to an H level, then the image data DT based only on image data ODT, EDT of a specific system are outputted. That is, required image data are obtained at a desired time. In this case, an output period of the image data by the single output, is changed to double (n times) the output period at the synthesis output, via an output period changeover means 37, then a timing margin relating to the processing of the image data is increased. Thus, in the case of peak detection, for example, a peak is detected at a required minimum clock speed through the single output. |
