Abstract
Official abstract text for this publication.
An image processing apparatus includes a focus lens, an image sensor which captures an image and a controller which moves the image sensor or the focus lens. A distance measurer measures a distance to a subject based on a first image and a second image. A focal position moves for the first focal range by moving the image sensor or by moving the position of the focus lens during the first exposure time period, and the focal position moves for the second focal range by moving the image sensor or by moving the position of the focus lens during the second exposure time period.
First claim
Opening claim text (preview).
The invention claimed is: 1. An image processing apparatus, comprising: a focus lens; an image sensor that, through the focus lens, captures a first image for a first focal range during a first exposure time period and a second image for a second focal range during a second exposure time period, wherein the first focal range and the second focal range are different; a controller configured to move the image sensor or the focus lens; and a distance measurer configured to meas…
