Publication number: 20150271484Abstract: An image capturing apparatus includes an input unit, a detecting unit, and a controller. The input unit continuously inputs a signal sequence. The signal sequence includes values of multiple pixels and control information. The pixels constitute an image. The control information is embedded at multiple positions according to a rule. The detecting unit detects occurrence of an error on the basis of the inputted control information. The controller interrupts the input performed by the input unit when the detected error is based on the control information embedded in a first region of the image, and continues the input when the detected error is based on the control information embedded in a second region.Type: ApplicationFiled: February 6, 2015Publication date: September 24, 2015Inventors: Yuichi KAWATA, Nobuaki SUZUKI, Hideki YAMASAKI, Tomitsugu KOSEKI, Yoshifumi BANDO, Kensuke OKAMOTO
