An apparatus connects to a power source device and an external apparatus, controls power input from the power source device and power output to the external apparatus, steps up or steps down voltage of the power input from the power source device, and sets a path through which the power input from the power source device is output to the external apparatus. The apparatus acquires attribute information of the power source device and required voltage of the external apparatus and, performs control, based on the attribute information and the required voltage, to switch between a path through which the power input from the power source device is output to the external apparatus via a voltage conversion, and a path through which the power input from the power source device is output to the external apparatus not via the voltage conversion.

Electronic apparatus and control method

An apparatus includes a generating unit and a transmitting unit. The generating unit generates synchronization format information regarding a vertical synchronizing frequency and a horizontal synchronizing frequency of a first video synchronizing signal, and generates phase difference information indicating a phase difference between the first video synchronizing signal and a first reference signal synchronized with a grand master clock. The transmitting unit transmits the synchronization format information and the phase difference information to an external apparatus that can generates a second video synchronizing signal synchronized with the first video synchronizing signal.

Apparatus of synchronizing a video synchronizing signal with another signal and method of controlling the apparatus

This invention provides an image processing apparatus including a unit which generates index image data, a unit which obtains a position of thumbnail image data in the index image data, a unit which divides the index image data so as to prevent overlap of the thumbnail image data, a unit which calculates a histogram of a luminance value of image data corresponding to each partial area including the thumbnail image data, a unit which determines image correction characteristics of each piece of image data based on the histogram and performing image correction, and a unit which reconfiguring the index image data using the corrected image data to output the reconfigured index image data.
