Abstract: The present technology relates to an information processing device and an information processing method, a solid-state imaging device and a solid-state imaging device operation method, a program, and an electronic apparatus in which an IC having an AF lens drive control unit mounted therein is made compatible with various communication specifications that vary with the types of lens driver ICs to be connected. A digital analogue converter (DAC) code for controlling a lens driver IC that controls driving of an actuator that drives a focusing lens is generated. A communication format related to serial communication is set in accordance with the lens driver IC, and is stored. The DAC code is buried in the communication format, to form a format compatible with the lens driver IC. Control is performed to cause the DAC code to be transmitted to the lens driver IC through serial communication. The present technology can be applied to imaging apparatuses.

Abstract: Disclosed herein is an image pickup apparatus including, a lens driving control section configured to execute driving control of a lens, and a main control section configured to produce lens driving control information as setting information of a lens driving mode of the lens driving control section, the main control section produces lens driving control information which includes a final setting position for the lens and a returning amount as a distance over which the lens is returned after the lens passes the setting position, the lens driving control section being operable to execute a process of moving the lens to pass the setting position once in response to the setting position and the returning amount and then execute a returning process by the returning amount to position the lens to the setting position.

Abstract: An image pickup apparatus includes an imaging element having a group of AF pixel pairs that realizes a pupil-dividing function and a group of normal pixels without such a pupil-dividing function. The image pickup apparatus performs focus control for driving a focus lens toward an in-focus position detected by phase different AF based on a pixel signal generated from the group of AF pixel pairs when it is determined that the reliability of the phase difference AF is high based on the pixel signal. The image pickup apparatus performs focus control for driving a focus lens in an in-focus direction detected by contrast AF based on a pixel signal generated from the group of normal pixels when it is determined that the reliability of the phase difference AF is low.

Abstract: An imaging device includes an imaging unit that obtains an image signal relating to a subject, a driving unit that drives a focus lens, a first detecting unit that performs focus detection based on a contrast detection method to detect an in-focus position of the focus lens, a second detecting unit that performs focus detection based on a phase difference detection method, while the focus lens is being driven toward the in-focus position, to detect a provisional in-focus position of the focus lens, and an in-focus control unit that controls the driving unit to drive the focus lens to pass through the provisional in-focus position and then return to the in-focus position. Focus detection information is obtained at least for a given range of positions, and is stored in a predetermined storage unit. The in-focus position is detected based on the stored focus detection information.

Abstract: A region in a captured image is set as a signal detection region, and signals from an CMOS sensor of the rolling shutter exposure type are detected only in an exposure period corresponding to the signal detection region to produce an evaluated value, after which a focusing lens is moved to a focusing lens position for acquiring a next evaluated value. Since the signal detection region is a partial region in the captured image, a long detection quiescent time is kept between signal detection periods corresponding to every two horizontal synchronizing periods. By moving the focusing lens in the detection quiescent time, the evaluated value is acquired and the focusing lens is moved in each horizontal synchronizing period.
