Abstract: An iris detection device includes a candidate detection unit, a candidate narrowing-down unit, and an iris specifying unit. The candidate detection unit detects circular regions as iris candidates from images captured by an infrared camera. The candidate narrowing-down unit narrows down the detected iris candidates into a predetermined number of iris candidates with use of data items of images of surroundings of each of the iris candidates. The iris specifying unit specifies one of the predetermined number of iris candidates obtained by the narrowing-down as an iris by matching between gradients of a contour of each of the predetermined number of iris candidates and iris templates.

Abstract: A target setting apparatus sets a target correcting a sight line detection portion to detect a sight line of a subject person. A deviation between a position of the target and a position detected as a center of the sight line detected by the sight line detection portion when the subject person is estimated to be gazing at the target is regarded as a detection error and applied to a correction. The target setting apparatus includes: a sight line range estimation portion that estimates a sight line range; a candidate point extraction portion that extracts a candidate point for the target from the sight line range; a candidate point evaluation portion that evaluates appropriateness of the candidate point as the target by using a plurality of indices; and a target setting portion that determines whether or not to set the candidate point as the target.

Abstract: A sight line input apparatus includes: a display portion that displays an input item at a position where the input item is viewable from a driver seat; a setup portion that sets a virtual input region at a position displaced from a display region of the display portion toward a driving visual field of the driver, the virtual input region being associated with the input item; a detection portion that detects a sight line position of a driver; and an input controller that performs an input process in accordance with the input item associated with the virtual input region, when the sight line position is in the virtual input region set by the setup portion. When a predetermined operation of the driver is detected, the setup portion changes the virtual input region into a mode that permits the driver to gaze at the virtual input region with ease.

Abstract: In a display control device displaying a cursor on a display screen image based on detection results of a direction of a sight line and a manual operation of a user, a display control unit suspends a sight cursor display processing when a manual operation detection unit does not detect the manual operation of an operation device even when a sight detection unit detects the direction of the sight line with respect to the display screen image. Even when the user only moves the sight line to see a content displayed on the display screen image, the cursor is not displayed over the content. The sight cursor display processing is allowed to be executed by an action ordinary for the user such as usage of the operation device when moving the cursor. Accordingly, user's convenience can be improved.

Abstract translation: 在基于视线的方向和用户的手动操作的检测结果在显示屏幕图像上显示光标的显示控制装置中，当手动操作检测单元不被显示时，显示控制单元暂停观察光标显示处理 即使当视觉检测单元相对于显示屏幕图像检测到视线的方向时，也检测操作装置的手动操作。 即使用户仅移动视线来看到显示屏幕图像上显示的内容，也不会在内容上显示光标。 允许通过用户操作的动作来执行视光标显示处理，例如当移动光标时操作装置的使用。 因此，可以提高用户的便利性。

Abstract: A sight line input parameter correction apparatus includes: an image acquisition portion that acquires a face image of a user; a sight line detection portion that detects a line of sight position of the user; a gaze point map generation portion that specifies areas where a line of sight remains on a screen of a display device; a storage device that stores information on an image group displayed on the display device; and a correction portion that compares the areas obtained by the gaze point map generation portion with the information on the image group, estimates correlations between the areas and images of the image group, and corrects a parameter of the sight line detection portion. The correction portion does not correct the parameter when a total number of the areas specified by the gaze point map generation portion is less than a predetermined number.

Abstract: A line of sight measurement device includes an imaging unit and a line of sight measurement unit. The imaging unit includes a variable exposure level and is configured to capture an image of a subject. The line of sight measurement unit measures a line of sight direction of the subject based on the image captured by the imaging unit. The imaging unit is configured to continuously alternate between capturing a first image showing an entire face of the subject at a first exposure level, and capturing a second image showing an area around the eyes of the subject at a second exposure level set higher than the first exposure level. The line of sight measurement unit is configured to correct a positional deviation between the first image and the second image.
