An image taking apparatus includes: a photoelectric conversion unit including a plurality of photoelectric conversion elements, the photoelectric conversion elements disposed in a two-dimensional matrix, the photoelectric conversion elements converting received light into electric charge and accumulating the electric charge; an image sensor having a function of controlling an exposure time of each of the photoelectric conversion elements of the photoelectric conversion unit on a line-by-line basis; an area division unit for logically dividing the photoelectric conversion unit into an N number of uniform areas on the basis of information related to a taken image of a subject, each of the uniform areas including a line having some of the photoelectric conversion elements, N being a natural number of two or more; an interlaced scanning unit for scanning the photoelectric conversion elements in the first to N-th areas by M lines starting with a predetermined line in a predetermined area of the first to N-th areas while changing an area to be scanned to another area in a predetermined order each time the M lines are scanned, M being a natural number of one or more; and a pixel signal reading unit for reading, from each of the photoelectric conversion elements scanned by the interlaced scanning unit, a pixel signal including an electric signal corresponding to an amount of electric charge accumulated in each photoelectric conversion element.
