Patent number: 10719171Abstract: A projection type image display device correctly detects the position of contact of an electronic pen and a finger on a manipulation surface without the provision of a touch sensor. Light containing an image is projected, illuminating light that is different from the light containing the image is projected onto a manipulation surface which at least partially overlaps an image projection surface onto which the light has been projected, and an image of the manipulation surface is captured. A first detection process detects the position at which a first object being manipulated, a distal end of which emits light, touches the manipulation surface, a second detection process detects the position at which a second object being manipulated, which does not emit light, touches the manipulation surface, and at least part of the image being displayed is changed on the basis of the detection result from either detection process.Type: GrantFiled: June 15, 2018Date of Patent: July 21, 2020Assignee: Maxell, Ltd.Inventors: Sakiko Narikawa, Takashi Matsubara, Naoki Mori

Patent number: 10514806Abstract: An operation detection device includes: first and second illuminations that irradiate illumination light from different positions onto an operation surface on which a user performs an operation, and a camera that captures the operation surface together with at least two fingers of a same hand of the user. First and second shadows of a same hand of the user are extracted from captured images obtained by the camera. Respective touch points of the same hand of the user on the operation surface are detected including when the first and second shadows corresponding to first and second fingers of the same hand have overlapping areas.Type: GrantFiled: May 23, 2016Date of Patent: December 24, 2019Assignee: Maxell, Ltd.Inventors: Takashi Matsubara, Sakiko Narikawa, Naoki Mori

Patent number: 10191594Abstract: In a projection-type video display device that displays an image by projecting the image onto a projection object starting from a desk surface, a display screen on which a position and a gesture operation of a user are reflected is displayed in a predetermined area. An illumination and a camera are disposed in the projection-type video display device installed on the desk surface, a gesture using user's fingers is detected, and, for example, a menu screen and an operation guide are displayed according to the gesture. The shadows of the fingers are photographed by the camera, and a gesture is detected. According to the gesture, the display screen is moved, rotated, divided, or enlarged/reduced, or a menu screen is displayed. The display direction is determined in consideration of the direction of sides of the desk.Type: GrantFiled: February 6, 2018Date of Patent: January 29, 2019Assignee: MAXELL, LTD.Inventors: Minoru Hasegawa, Mitsuo Nakajima, Takashi Matsubara, Sakiko Narikawa

Patent number: 10152177Abstract: A shadow region extraction portion compares the brightness of an image captured by a camera with a threshold value and extracts first and second shadows caused by first and second light sources for a user's finger. An approach degree detection portion detects an approach degree for the finger with reference to a manipulation surface from distance d between two feature points in the first and second shadows. A contact point detection portion detects contact point P for the finger with reference to the manipulation surface from positions of the two feature points. A direction detection portion detects a direction pointed by the finger from directions of contours corresponding to the first and second shadows. A display control portion generates display control data for a manipulation target apparatus based on detection result data.Type: GrantFiled: February 4, 2014Date of Patent: December 11, 2018Assignee: MAXELL, LTD.Inventors: Sakiko Narikawa, Takashi Matsubara, Naoki Mori
