Patent number: 11356615Abstract: A camera device includes a first IR illuminator that is configured to irradiate a first irradiation range in a capturing area with first IR light, a second IR illuminator that is configured to irradiate a second irradiation range narrower than the first irradiation range in the capturing area with second IR light, and a controller that is configured to obtain a zoom magnification of the lens and controls the irradiation of the first IR light and the second IR light in a case where the zoom magnification is equal to a predetermined zoom magnification. The controller changes a supplied current of the first IR illuminator for the irradiation of the first IR light over a first predetermined time period, and changes a supplied current of the second IR illuminator for the irradiation of the second IR light over a second predetermined time period.Type: GrantFiled: May 27, 2021Date of Patent: June 7, 2022Assignee: PANASONIC I-PRO SENSING SOLUTIONS CO., LTD.Inventors: Tatsuya Tamaru, Satoshi Kataoka, Daisuke Hara, Hiroki Yamanaka

Patent number: 7012708Abstract: An IFAX on a transmitting end gains access to an ISP on the transmitting end by dialup. The IFAX on the transmitting end transmits mail transmission notice to an IFAX on a receiving end via a PSTN after transmitting e-mail to the ISP on the transmitting end. Thereafter, the IFAX on the receiving end gains access to an ISP on the receiving end by dialup in accordance with mail transmission notice and receives e-mail stored in its own postbox. The mail transmission notice is performed using a facsimile communication protocol. The mail transmission notice includes at least one of transmission finished notice information, sent data information, and receiving information. This eliminates the unavailing mail check connection and reduces access charge at a dialup IFAX of the Internet facsimile.Type: GrantFiled: March 28, 2001Date of Patent: March 14, 2006Assignee: Panasonic Communications Co., Ltd.Inventor: Tatsuya Tamaru

Patent number: 6339684Abstract: The recording apparatus of the present invention acquires time data from a clock built in the main body of the apparatus, and generates first calculation data by calculating the time data with a predetermined calculation method. Meanwhile, in the cartridge attached to the main body, the time data is acquired from the main body, and second calculation data is generated by calculating the time data with the same calculation method as the above-mentioned predetermined calculation method. As a result of comparing the first calculation data to the second calculation data, it is judged that the attached cartridge is proper when both of the data match, and it is judged that the attached cartridge is not proper when both of the data do not match. It is thereby possible to judge whether or not the cartridge attached to the main body is proper.Type: GrantFiled: February 9, 2000Date of Patent: January 15, 2002Assignee: Matsushita Graphic Communication Systems, Inc.Inventors: Tamotsu Sato, Tatsuya Tamaru
