Abstract: An operation apparatus operates an electronic device. The operation apparatus includes a receiver configured to receive a first image from the electronic device; an image generator configured to generate a second image including the first image received by the receiver; a message setter configured to set a message corresponding to a status of the electronic device, with respect to the first image included in the second image; a display configured to display the second image; and a voice sound outputter configured to output, by voice sound, the message set with respect to the first image, in response to a user operating the first image included in the second image being displayed.

Abstract: An information processing apparatus includes circuitry. The circuitry controls a display to display a symbol corresponding to operation by a user during a first period of time since occurrence of the operation. The circuitry controls output of an image indicating a content displayed on the display to an external apparatus, so as not to output the image to the external apparatus during a second period of time that is equal to or longer than the first period of time.

Abstract: An image processing apparatus includes: an embed-data generating unit configured to generate embed-data, which is to be embedded in input-image-data, the input-image-data representing an image including a first color, the embed-data representing an image including a second color; an inverting unit configured to invert the image represented by the embed-data, in response to meeting a predetermined condition relating to the first color and the second color; and an output-image-data generating unit configured to embed, in the input-image-data, embed-data representing the image that is inverted by the inverting unit, in order to generate output-image-data in a case where the predetermined condition is met, and configured to embed, in the input-image-data, embed-data representing the image that is not inverted by the inverting unit, in order to generate output-image-data in a case where the predetermined condition is not met.

Abstract: An image processing apparatus includes: an operation receiver, an image processor configured to perform image processing to add a digital watermark containing address information of the image processing apparatus to a first image to thereby generate a second image; a communication controller configured to receive a taking-out request to take out the digital watermark contained in the second image from an information processing device; and a storage controller configured to store a log in a storage unit. When receiving the taking-out request, the image processor performs image processing to take out the digital watermark contained in the second image to thereby generate the first image. The communication controller transmits the first image generated by the image processor to the information processing device.
