Image pickup system and lens apparatus

摘要

The image pickup system includes a lens apparatus (1) and a camera (2) configured to perform image pickup of objects in an image pickup area using the lens apparatus. The lens apparatus includes a ranging sensor (120) configured to simultaneously detect object distances in plural ranging areas set in the image pickup area. The image pickup system includes an output image generator (203) configured to generate an output image containing (a) a captured image captured by the camera and (b) distance information showing at least one of the object distance detected by the ranging sensor in each of the plural ranging areas and a difference between the detected object distances. The image pickup system is capable of displaying the object distances to plural objects or a difference therebetween without performing focusing for the respective objects.

主权项

1. An image pickup system comprising:
a zoom lens apparatus including a zoom state detector configured to detect a zoom position, among a plurality of zoom positions of the zoom lens; a ranging sensor configured to detect a phase difference between object images formed with light entering the lens apparatus; a camera configured to perform moving image pickup of objects in an image pickup area through the lens apparatus; a first microprocessor programmed to execute:
a setting task that stores positions and sizes of plural ranging areas in relation to the ranging sensor in the image pickup area, and that changes at least one of positions or sizes of the plural ranging areas based on the zoom position detected by the zoom state detector and the stored positions and sizes; anda calculating task that calculates an object distance in each of the plural ranging areas based on an output from the ranging sensor; and a second microprocessor programmed to execute:
an output image generator task that generates an output moving image containing (a) a captured moving image captured by the camera and (b) distance information indicating at least one of the object distance calculated by the calculating task in each of the plural ranging areas or a relative distance calculated as a difference between the object distances calculated by the calculating task in the plural ranging areas, to be displayed on a display device.
