US Patent 7397611 Image capturing apparatus, image composing method and storage medium

In a digital camera 1, when the halfway depression operation of the shutter button is detected, the lens position which is in focus for each capture area is detected and stored. On the other hand, when instruction to record is detected, intensity of light is sequentially read out at the stored lens position from the capture area associated with the lens position and the image data is generated. Accordingly, it is possible to acquire image data which is in focus on all objects that have been imaged by the CMOS sensor 4.
