An image-capturing apparatus is provided. The image-capturing apparatus has an imaging sensor, a controller, and a communication interface. The controller controls operation timings of the image-capturing apparatus. The communication interface outputs an image captured by the imaging sensor and control information of the imaging sensor to the outside at timings controlled by the controller. The controller can control the operation timings of the image-capturing apparatus in accordance with a synchronization signal input to the image-capturing apparatus. The controller synchronizes the synchronization signal and the operation timings of the image-capturing apparatus before the control information is output to the outside, when an instruction to output the control information to the outside is input while the synchronization signal and the operation timings are not synchronized.

Image-capturing apparatus, control method, and storage medium

An image capturing apparatus comprising a processor executing instructions. The instructions cause the image capturing apparatus to: obtain a driving frequency in which the image capturing apparatus is capable of operating; and obtain a frequency of a synchronization signal inputted from an external device, the synchronization signal being used for outputting a video obtained by the image capturing apparatus. The instructions further cause the image capturing apparatus to: determine whether the driving frequency and the frequency of the inputted synchronization signal satisfy a predetermined relationship; and output, in a case where it is determined that the predetermined relationship is not satisfied, information of a warning message indicating that the inputted synchronization signal is incorrect.

An information processing apparatus comprises: an output unit configured to perform video output to an external apparatus; a switching unit configured to switch an operation mode of the information processing apparatus between a first mode in which the video output by the output unit is performed and a second mode in which the video output by the output unit is not performed; and a synchronization control unit configured to, in the video output by the output unit, control whether or not to perform Genlock based on an external synchronization signal inputted from an external unit. The synchronization control unit, in a case where an instruction for performing Genlock has been received while operating in the first mode and not performing Genlock, prevents start of Genlock while operating in the first mode.

An inter-vehicle communication and driving assistance device performs wireless communication with other vehicles, and includes an inter-vehicle communication unit including a reception level detection unit, a position information reception unit, and an arithmetic processing unit. The arithmetic processing unit calculates inter-vehicle distances to other vehicles using latitude and longitude information of the other vehicles and the own vehicle, receives a position error radius, and acquires a reception level from the other vehicles. When a difference between the inter-vehicle distances is smaller than position error radius, a vehicle with a larger reception level is determined as a vehicle closer to the own vehicle. When the difference between the inter-vehicle distances is larger than the position error radius, a vehicle with a smaller inter-vehicle distance is determined as a vehicle closer to the own vehicle, and a distance to a leading vehicle is calculated.

The invention efficiently realizes time division multiplexed channel access in a mixture of a vehicle-to-vehicle communication device using an approximate frequency band and a direct mobile communication terminal. The vehicle-to-vehicle communication device includes a mobile communication unit, a threshold storage unit that stores a threshold value as to whether or not a predetermined control channel for vehicle-to-vehicle communication is an idle channel, a level detector that outputs a predetermined detection signal when a radio wave intensity of the predetermined control channel is larger than the threshold value, and a timer unit that transmits a signal to the level detector when the time counting for a predetermined time expires. The mobile communication unit transmits the radio wave of the direct communication of the mobile communication when the level detector receives the signal and the radio wave strength of the predetermined control channel does not exceed the threshold value.

Vehicle-mounted communication device and communication method

Upon detecting input of an instruction to change a display layout of a document on a display screen, display control of the document on the display screen is performed so that a character output as a voice by a voice output unit at the time of detection is displayed on the display screen.

Information processing apparatus and information processing method

The present invention provides a technology for enabling a natural voice reproduction in which, depending on a gazed character position, a position of a voice output character follows but not excessively reacts with the gazed character position. Therefore, in an electronic device provided with a display unit for displaying text on a screen, a voice outputting unit for outputting the text as voice, and a sight-line detection unit for detecting a sight-line direction of a user, a control unit changes a starting position at which a voice outputting unit starts voice output if a distance between the position of the current output character and the position of the current gazed character is a preset threshold or more.

A page designated by a page designation instruction of those included in an electronic book is displayed. When a voice output instruction is input, a page displayed at that input timing is set as a voice output page, and voices corresponding to respective characters in the voice output page are sequentially output in accordance with an arrangement order of the characters. A start character from which a voice output operation is started is determined based on characters in the voice output page, and voices corresponding to characters, which include the start character and subsequent characters, are controlled to be sequentially output in accordance with the arrangement order.

Information processing for outputting voice

An information processing apparatus may include a detection unit and a switching unit. The detection unit detects an amount of change in a position of an object of interest per a predetermined time period. The switching unit switches between a first mode for determining a first operation position on a display surface based on the position and direction of an object of interest and a second mode for determining a second operation position on the display surface based on a position where the object of interest is in contact with the display surface using the detected amount of change.
