Publication number: 20230209188Abstract: An image processing apparatus detects, from an image, a subject(s) of a first type and a subject(s) of a second type. The apparatus further detects a posture for each of the subject(s) of the first type. The apparatus then obtains, for each of the subject(s) of the first type, reliability that the subject is a main subject, based on the posture, and obtains a focus condition for each of the subject(s) of the first type and each of the subject(s) of the second type. The apparatus determines, based on the reliability and the focus condition, a main subject from the subject(s) of the first type and the subject(s) of the second type detected from the image.Type: ApplicationFiled: December 16, 2022Publication date: June 29, 2023Inventors: Akihiko KANDA, Hiroshi Yashima, Hideki Ogura, Hideyuki Hamano

Patent number: 9016842Abstract: A liquid container and an apparatus in which the liquid container is mountable are provided, the liquid container and the apparatus enabling the presence or absence of remaining liquid to be checked without the need for a power source and even after the liquid container is removed. The pressure in a communication path is maintained while ink in a containing section is not supplied to the exterior. Thus, the displacement state of a detection valve which is displaced depending on the pressure in the communication path can be maintained even after removal of an ink tank.Type: GrantFiled: February 25, 2014Date of Patent: April 28, 2015Assignee: Canon Kabushiki KaishaInventors: Takeho Miyashita, Yasuo Kotaki, Koichi Kubo, Hitoshi Takada, Tatsuo Nanjo, Hideki Ogura, Hironori Murakami, Hideo Fukazawa, Eiichi Adachi

Patent number: 8770730Abstract: A liquid container enables a liquid contained in a liquid containing chamber to be supplied to an exterior through a supply port. The liquid container includes a first channel, a second channel, and a communication path. The first channel is in communication with a first opening which opens into the liquid containing chamber. The second channel is in communication with a second opening which opens into the liquid containing chamber, the second opening being positioned above the first opening in a direction of gravitational force. The communication path allows the first channel and the second channel to communicate with each other outside the liquid containing chamber to permit a flow of the liquid.Type: GrantFiled: February 14, 2013Date of Patent: July 8, 2014Assignee: Canon Kabushiki KaishaInventors: Tatsuo Nanjo, Yasuo Kotaki, Hitoshi Takada, Koichi Kubo, Hideki Ogura, Hironori Murakami, Takeho Miyashita, Hideo Fukazawa, Eiichi Adachi
