Patent ID: 8908060

Claim:
An imaging apparatus comprising: an image data interface unit that outputs image data according to a pixel signal input from a solid-state imaging device as first image data, the pixel signal having a first frame rate; an image data reading unit that reads image data stored in a storage unit via a data bus and outputs the read image data as second image data; an image synthesis unit that synthesizes image data based on the first image data with image data based on the second image data to generate and output third image data having a second frame rate; an evaluation value generation unit that generates an evaluation value based on input image data, the evaluation value having the first frame rate; a first image data selection unit that selects any one of the image data based on the first image data, the image data based on the second image data, and the third image data as image data to be input to the evaluation value generation unit; an image data writing unit that stores input image data in the storage unit via the data bus; a second image data selection unit that selects any one of the image data based on the first image data, the image data based on the second image data, and the third image data as image data to be input to the image data writing unit; and a display unit that reads the third image data stored in the storage unit by the image data writing unit, from the storage unit via the data bus and displays an image according to the third read image data, wherein the first frame rate is higher than the second frame rate.
