Embodiments are directed to devices and methods including a time-of-flight sensor and a camera. In one embodiment, a device is provided that includes a time-of-flight sensor, distance estimation circuitry, a camera, and processing circuitry. The time-of-flight sensor transmits an optical pulse signal and receives return optical pulse signals corresponding to portions of the transmitted optical pulse signal reflected by an object. The distance estimation circuitry estimates a minimum distance to the object based on a time between transmitting the optical pulse signal and receiving a first portion of the return optical pulse signals, and estimates a maximum distance to the object based on a time between transmitting the optical pulse signal and receiving a second portion of the return optical pulse signals. The processing circuitry controls a focus distance and an aperture setting of the camera based on the estimated minimum and maximum distances to the object.

An electronic device comprises an adjustment unit for adjusting a focus distance of a lens unit and obtainment unit for obtaining, from the lens unit, first information relating to a first range and second information relating to a second range. The first range being a focus range of the lens unit, and the second range being a focus range, in the first range, in which adjustment by the adjustment unit is limited. The electronic device controls, on the basis of the first information and the second information, the display device so as to display the first range and the second range to be distinguishable from each other.

An imaging device, comprising an image sensor that receives subject light and generates image data, and a processor comprising a focus control section, an index generating section, and a control section, wherein the focus control section performs focus detection based on the image data, and controls focus drive based on focus detection results, the index generating section is input with the image data, and generates a first index representing which image of a given plurality of types of image the image data is close to, and a second index representing Bokeh state of an image corresponding to the image data, and the control section changes control of focus drive by the focus control section based on output of the index generating section.

A lens apparatus attachable to an image pickup apparatus includes an imaging optical system, and a communicator configured to communicate with the image pickup apparatus. The communicator transmits to the image pickup apparatus first information used to calculate a depth of field and second information used to normalize the depth of field into a display format of a display unit of the image pickup apparatus.

A microscopy method for imaging an object includes: imaging the object into an optical image onto an image detector, generating electronic image data from the optical image using the image detector and generating an electronic image from the electronic image data, defining a region of interest in the electronic image, determining a depth distribution in the region of interest and/or in a region of the object corresponding to the region of interest, determining a desired depth region in the depth distribution, selecting at least one imaging parameter with which a size of a depth-of-field region can be changed, and setting the depth-of-field region of the electronic image by changing the at least one selected imaging parameter such that the depth-of-field region covers the desired depth region or covers a specific portion thereof.

The control method includes determining whether a plurality of pupils can be included in a specific depth in a case where pupil information about the plurality of pupils of a same subject is acquired, and in a case where it is determined in the determining that the plurality of pupils of the same subject cannot be included in the specific depth, control is performed so that different indexes are displayed on a pupil within the specific depth and a pupil outside the specific depth.

Provided are an imaging apparatus and an imaging method capable of relatively accurately focusing on a main object in a relatively short time. A movement region (40) of a main object OA is imaged in a camera apparatus A and a different camera apparatus B. In the camera apparatus A, the main object OA is recognized from a captured image. Data indicating the position of the main object OA, transmitted from the camera apparatus B, is received in the camera apparatus A, and a focusing target range is set at the front and back of the position of the main object OA. A movement of a focus lens of the camera apparatus A is limited so as to focus on the focusing target range.
