An image capture apparatus according to an embodiment of the present technology includes an image generation unit, an edge detection unit, and a color control unit. The image generation unit generates a captured image by capturing a subject. The edge detection unit detects an edge portion included in the generated captured image. The color control unit controls a color of a highlighted display for highlighting the edge portion for each detected edge portion based on color information about the edge portion in the captured image.

A control apparatus 220 controls the in-focus positions of a plurality of image capturing apparatuses that perform image capturing from a plurality of directions in order to generate a virtual-viewpoint image. Specifically, the control apparatus 220 obtains an image capture parameter related to image capturing by one or more image capturing apparatuses included in an image capturing apparatus group 100. The control apparatus 220 controls on the basis of the obtained image capture parameter, the in-focus position of a target image capturing apparatus corresponding to the image capture parameter such that the distance from the target image capturing apparatus to the in-focus position of the target image capturing apparatus is shorter than the distance from the target image capturing apparatus to a point of interest.

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.
