  • Patent number: 9338120
    Abstract: To provide an e-mail system for ensuring that a user is able to know content of an e-mail sent addressed to the user even when the e-mail is not delivered to the user. An e-mail sending unit (220) sends an e-mail sent addressed to the alternative mail address of the user to the actual mail address of the user, after setting a predetermined destination as a destination of a notice of failed delivery, if caused, of the e-mail. In a case where the notice of failed delivery of the e-mail sent addressed to the actual mail address of the user is received by the predetermined destination, an undelivered mail data saving unit (230) saves undelivered mail data indicating the undelivered e-mail in an undelivered mail data storage unit (410). An undelivered mail data sending unit (110) sends undelivered mail data indicating an e-mail sent addressed to the actual mail address of the user and failed to be delivered to a terminal device used by the user.

  • Patent number: 9313422
    Abstract: Provided is a video processing device with which it is possible to efficaciously carry out a process of superpositioning a monitor character signal in a video signal which is inputted from a camera and outputting same separately from the video signal. The video processing device comprises: a character signal emitter which generates a character signal on the basis of the monitor data; and a character superposition unit which superpositions the character signal which is generated by the character signal emitter upon the least significant bits of the color difference signal of the video signal which is inputted from the camera. With respect to downconverting the video signal whereupon the character signal has been superpositioned, only a downsampling process on the least significant bits of the color difference signal is carried out, and an interpolation filter process is not carried out.

  • Patent number: 7679566
    Abstract: An antenna structure includes a radiation conductor made of a metal plate that is supported by legs provided upright on a surface of a dielectric substrate and is spaced apart from the surface. The radiation conductor is circularly shaped such that the contour of the radiation conductor conforms to the outer periphery of the dielectric substrate and such that the radiation conductor includes an open portion. One of the legs functions as a feeding terminal and the other functions as a grounding terminal, whereby the radiation conductor operates as a dipole antenna. The radiation conductor has slots for adjusting impedance. Impedance can be adjusted by changing the length of the slots.

  • Patent number: 7206020
    Abstract: An adaptive white defect correction method and an image-pickup apparatus implementing the method. Pixel data on lines located above and below a white defect pixel are judged according to a predetermined algorithm to determine which of a plurality of previously supposed kinds of pattern most resembles an image obtained near a white defect pixel. On the basis of a result of the determination, suitable interpolation data is generated. As for the determination of the image pattern, a pair of two pixels are selected from pixels on the lines located above and below the white defect pixel, and processing of determining whether there is correlation between pixel values of the selected pixels is repetitively executed until a image pattern near the white defect pixel is determined.
