Abstract: The semiconductor device includes an image signal processor, a scaler, and an ROI (Region of Interest) controller. The image signal processor executes image processing including demosaic processing and stores the image after the image processing in memory. The scaler reduces the capture image from the image sensor to generate a reduced entire image and causes the image signal processor to execute image processing on the reduced entire image. The ROI controller cuts out a partial region of the captured image from the image sensor to generate an ROI image and causes the image signal processor to execute image processing on the ROI image.

Abstract: A semiconductor device (100) according to an embodiment calculates the number of times of burst access for an address set (A) based on a result of a determination, for each of N addresses a1 to an (N is a natural number no less than two) included in the address set (A), whether or not the address and another address adjacent to that address in an accessing order can be accessed by the same burst access, and calculates an access time that will be taken for accessing the address set by the burst access.
