An electronic device comprising a connecting section; a first IF circuit that communicates through the connecting section with an external device connected via the connecting section, at a first communication speed; a second IF circuit that communicates through the connecting section with the external device, at a communication speed that is higher than the first communication speed; and a control section that, when one of the first IF circuit and the second IF circuit is selected as an IF circuit to be used for communication, limits a power supply to the other IF circuit.

Electronic device and computer readable medium

An image-capturing device including an image-capturing element, a data extraction device, a recording device, a reproduction device, and a display control device is provided. The image-capturing element captures an image of a photographic subject and outputs image data. The data extraction device extracts data corresponding to a region designated in advance within the image data outputted from the image-capturing element. The recording device records the extracted data and the image data into a recording medium individually. The reproduction device reads out the extracted data from the recording medium. The display control device outputs an image signal to a display device, so as to display an image according to the extracted data read out by the reproduction device.

Image-capturing and data extraction device

An electronic device includes: a data transfer unit that transfers data between a first recording medium and a second recording medium; an indication unit that indicates a communication protocol and a data transfer rate to be used in data transfer to the transfer unit; a judgment unit that judges whether or not the data transfer is successful; a control unit that controls the indication unit to indicate a communication protocol and a data transfer rate to be used in data transfer, after the judgment whether or not the data transfer is successful, based on the communication protocol used in the data transfer, the data transfer rate used in the data transfer, and the judgment whether or not the data transfer is successful.

Electronic device, electronic camera, and data transfer program for changing transfer rate and communication protocol

An electronic still camera includes: a detection unit that detects whether or not a detachable recording medium has a cache function; and a validating unit that validates the cache function when the detection unit detects that the recording medium has the cache function.

Electronic still camera having cache control function

An electronic camera having a continuous shooting function includes a resolution conversion unit capable of performing resolution conversion at least at a high resolution and at a low resolution that is lower than the high resolution, an image compression unit capable of performing image compression at least at a low compression factor and at a high compression factor that is higher than the low compression factor, and when a continuous shooting unit executes continuous shooting, the image compression unit performs image compression at a high compression factor if the resolution at the resolution conversion unit is set to a low resolution.

Electronic camera having continuous shooting function

A data recorder includes a recording unit, a condition determining unit, and an optimizing unit. The condition determining unit performs a recording test or information acquisition on a recording medium, and determines from the result the right condition for performing a recording operation. The optimizing unit optimizes the recording operation according to the right condition. The recording unit performs the recording condition optimized by the optimizing unit, thereby recording data on the removable recording medium.

Electronic camera having function for optimizing recording operation

An image-capturing device according to the present invention includes: an image-capturing element which captures an image of a photographic subject and outputs image data; a data extraction device which extracts data corresponding to a region designated in advance within the image data outputted from the image-capturing element; a recording device which records the extracted data and the image data into a recording medium individually; a reproduction device which reads out the extracted data from the recording medium; and a display control device which outputs an image signal to a display device, so as to display an image according to the extracted data read out by the reproduction device.
