Claim:
1. An imaging apparatus comprising: a DRAM; a plurality of image processing units each configured to process image data corresponding to a plurality of image frames, and access the DRAM; a recording unit configured to record the image data processed by the image processing units in a recording medium, wherein the imaging apparatus has a plurality of modes including a first mode in which images associated with the plurality of image frames processed by the plurality of image processing units are displayed by a display device without recording the image data processed by the image processing units by the recording unit, and a second mode in which the recording unit records the image data processed by the image processing units, wherein the plurality of image processing units respectively access the DRAM in the first mode and the second mode; a data transfer controlling unit configured to control data transfer to the DRAM; a power controlling unit configured to control power consumptions of the plurality of image processing units; and a CPU configured to control the data transfer controlling unit and the power controlling unit in accordance with a current mode among the plurality of modes of the imaging apparatus, wherein the CPU controls the data transfer controlling unit, in accordance with the current mode of the imaging apparatus, to control a data amount accessed to the DRAM by remaining image processing units other than a predetermined one image processing unit of the plurality of image processing units while the predetermined one image processing unit processes a predetermined amount of image data, wherein the CPU controls the data transfer controlling unit so that a data amount accessed to the DRAM by the remaining image processing units while the predetermined one image processing unit processes the predetermined amount of image data in the first mode is smaller than a data amount accessed to the DRAM by the remaining image processing units while the predetermined one image processing unit processes the predetermined amount of image data in the second mode, and wherein the CPU controls the power controlling unit so that, in the first mode, power consumption of the predetermined one image processing unit after the predetermined one image processing unit ends the processing of the predetermined amount of image data is lower than power consumption of the predetermined one image processing unit while the predetermined one image processing unit processes the predetermined amount of image data.
