Abstract: A biological information estimating device includes: a detection unit configured to detect a pulse wave on a living organism; a modifying unit configured to determine whether or not the pulse wave contains disturbance and to modify a length of a measurement period based on a result of the determination; and an estimating unit configured to estimate biological information from the pulse wave detected in the measurement period.

Abstract: A mobile phone includes: a first image capturing element for generating left-eye image data; a second image capturing element for generating right-eye image data; a CPU; and a RAM. The CPU determines whether or not the left-eye image data includes an image of an obstacle, such as a finger, that blocks entrance of external light into the first image capturing element, and determines whether or not the right-eye image data includes an image of an obstacle that blocks entrance of external light into the second image capturing element. When one of the left-eye image data and the right-eye image data includes the image of the obstacle and the other of the left-eye image data and the right-eye image data does not include the image of the obstacle, the CPU deletes the one of the left-eye image data and the right-eye image data from the RAM.

Abstract: A transmitter is provided by which switching between two-dimensional display and three-dimensional display can be associated with data communication. When receiving a command for transmitting transmission data, a processor of the transmitter starts a process to transmit the transmission data to a receiver using a communication IF. When starting the process, the processor two-dimensionally displays an object on a display. After two-dimensionally displaying the object, the processor three-dimensionally displays the object on the display. During the three-dimensional display, the processor increases a stereoscopic amount of the object on the display with passage of time.

Abstract: An electronic device capable of simultaneously displaying in two-dimensional and three-dimensional fashions the same content. A flash memory of the electronic device stores first image data for two-dimensionally displaying the content, and second image data for three-dimensionally displaying the content. A CPU of the electronic device two-dimensionally displays the content on a display of the electronic device, using the first image data. When the CPU accepts an instruction for selecting the content displayed on the display, the CPU three-dimensionally displays the selected content on a display of a display device, using the second image data.
