The invention relates to an imaging apparatus, 19, that may be used in an image acquisition system, 1, (such as a scanning microscope) that scans an object, S, with an illumination light, 3. The imaging apparatus comprises a light receiving section, 19a, (such as a CMOS image sensor array) made up of a plurality of pixel rows (Figure 3, 19d), in which signal readout from the pixel rows is accomplished using a rolling (or continuous) readout method. An image control section, 19b, controls signal readout of the light receiving section based on a driving clock. This is achieved by changing the frequency of the driving clock and counting the number of driving clock pulses defining an interval of signal readout between adjacent pixel rows. The image control section may further control the count of the driving clock to synchronise the interval of signal readout between adjacent pixel rows and the scanning of the object with the illumination light.
