[Problem] To provide a charging system that levels the amount of grid power that is used, and that is capable of reducing power rates, even if charging has been frequently conducted without limiting the time zones in which charging is conducted. [Solution] A charging system is provided with: a storage unit that is charged by consuming grid power supplied by a power company, and that supplies the stored power through discharge; and a charging unit that charges batteries by consuming power supplied by grid power and the storage unit. Power companies set a power rate that is higher the greater the maximum value of the amount of power supplied for each unit of time is. Furthermore, at least a single charge carried out by the charging unit is carried out over two units of time, and the storage unit supplies power to the charging unit in at least one unit of time other than said two units of time.

A receiver has a tuner for receiving a TV broadcast program and a modem for receiving an e-mail. Also, the receiver outputs a message if there exists any unopened e-mail. In addition, the receiver has a camera for sending a videophone image. A viewer in front of the receiver is recognized, and it is determined whether or not the recognized viewer matches the addressee of the unopened e-mail. If a result of the determination is negative, a message output operation is prohibited.

An output from a solid state image sensing device spatially modulated by a color filter is A/D converted and stored in a field memory. Digital signals read from the field memory during electronic zooming are successively delayed by 1H period by means of first, second and third 1H delay elements connected in series. The output from the field memory and outputs from the first, second and third 1H delay elements are separated into luminance components and line sequential color components by first to fourth Y/C separating circuits, respectively. A first set of three primary color signals are calculated based on outputs from the first, second and third Y/C separating circuits, and a second set of three primary color signals are calculated based on outputs from the second, third and fourth Y/C separating circuits. Three primary color signals corresponding to a new display point formed along with the execution of the electronic zooming function are formed based on the calculated two sets of three primary color signals, and a luminance signal corresponding to the new display point is formed based on outputs from the second and third Y/C separating circuits.

In an automatic focusing circuit of a video camera, automatic focusing operation is performed by a focus evaluating value formed in response to a video signal obtained by an image sensing circuit (4). A first focusing motor control circuit (15) controls the rotation of a focusing motor (3) so that a focusing lens (1) is once fixed in the position where the focus evaluating value takes the maximum value. A second focusing motor control circuit (17) changes the focusing motor (3), by a predetermined very small amount, to determine the slope of the focus evaluating value, which change is repeated until inversion of the slope, that is, the maximal point is detected. As a result, the position of the focusing lens is corrected at the maximal point of the focus evaluating value. When the correction amount exceeds a predetermined value, first automatic focusing operation by the first focusing motor control circuit (15) is resumed.

A master controller of a battery charge and discharge control apparatus is a device performing charge and discharge control on a group of a predetermined number of battery arrays, the battery arrays being connected together in parallel. The master controller acquires an entire charge or discharge instruction intended for the entire battery array group, starts charging or discharging each of the battery arrays at a uniform charge or discharge power value, acquires a charge or discharge status of each of the battery arrays after the beginning of the charge or discharge and compares the charge or discharge status with a predetermined charge or discharge set value for the entire battery array group, and changes the charge or discharge power value of each of the battery arrays based on a result of the comparison.

摘要:
A reproduced video signal of a VTR is applied to a jitter compensation circuit (100). The applied reproduced video signal is A/D converted by a phase modulated clock and after subjected to the adjustment of timing, the signal is written into a memory (4). A burst signal period is specified based on a timing of a horizontal synchronizing signal in the reproduced video signal and a jitter amount is detected based on a sampling phase of the A/D converted burst. Jitter compensation data is calculated based on this jitter amount. On this occasion, latest jitter compensation data is obtained based on the detected jitter amount and the jitter compensation data one horizontal period before. A timing for starting to write the A/D converted video data into the memory is defined based on high-order data of the calculated jitter compensation data, thereby cancelling large jitter components. On the other hand, a phase of a A/D converting clock is controlled based on low-order data of the jitter compensation data, thereby cancelling small jitter components.
