Abstract: An imaging element incorporates a reading portion that reads out captured image data at a first frame rate, a storage portion that stores the image data, a processing portion that processes the image data, and an output portion that outputs the processed image data at a second frame rate lower than the first frame rate. The reading portion reads out the image data of each of a plurality of frames in parallel. The storage portion stores, in parallel, each image data read out in parallel by the reading portion. The processing portion performs generation processing of generating output image data of one frame using the image data of each of the plurality of frames stored in the storage portion.

Abstract: Provided is an imaging apparatus capable of performing AF with a high precision regardless of an object while realizing increase in AF speed. When there is an AF instruction, photographing is performed while a focus lens is moved. AF evaluated values are calculated at every position of the focus lens by a contrast AF processing unit. The contrast AF processing unit calculates a sharpness in the vicinity of the maximal point of an evaluated value curve from three AF evaluated values, including the maximum value among calculated AF evaluated values and AF evaluated values calculated at positions in front and rear of a focus lens position corresponding to the maximum value, and position information of the focus lens corresponding thereto, and calculates a focusing position by a calculation method selected from among plural kinds of methods according to the sharpness.
