A traveling toy system is provided, in which it becomes possible to reduce the amount of information transmitted to a video display device. In the traveling toy system, a video camera, a video camera controller which is adjustably controls at least a frame rate of the video camera, a signal transmission device which transmits a video signal outputted from the video camera to a video display device, and electric storage means for power supply are mounted on the traveling toy which travels on a traveling lane using a potential energy. The traveling toy system further includes a traveling toy carrier device which carries the traveling toy from a position where the potential energy is low to a position where the potential energy is high. The video camera controller changes the frame rate so that when a traveling speed of the traveling toy is higher than a given speed, the frame rate may be increased from the frame rate at the time that the traveling speed is lower than the given speed.

An object of this invention is to finely set the voltage at high speed without decreasing the efficiency. In a power supply for switching operation including a switching circuit, an output circuit, a control table which stores data on the ON and OFF periods of the switching circuit in correspondence with a set voltage, an arithmetic processing unit which performs reading operation from the control table and PWM operation, and a digital control unit which controls the switching circuit by outputting a PWM signal, feedback control based on the output voltage is performed in a case where the output voltage is not changed. When changing the output voltage, the feedback control is switched over to control based on data in the control table to change the output voltage at high speed.

Travel time database generating systems, methods, and programs receive a vehicle's present location information and calculate a link travel time for each link included in the present location information. The systems, methods, and programs generate a travel time database including link travel times by estimating a travel route between the vehicle's present locations detected every predetermined time period and calculating a link travel time of links included in the estimated travel route.

There is provided an image data compression apparatus capable of effectively suppressing an image data volume after compression processing. A bit rate value is detected according to the image data volume after the compression processing. According to the bit rate size value detected, a quantization step size value used in the compression processing is modified. According to the quantization step size value, a skip frame number is set and a frame skip of the image data before or after the compression processing is performed according to the number of frame skip frames which has been set.

An image supply device capable of communicating with an image display device adapted to display an image with a predetermined display resolution, a display system, an image supplying method and an information recording medium are disclosed. The image supply device includes a transmission image data generator adapted to generate transmission image data with a resolution lower than a display resolution of the image display device, and a transmitter adapted to transmit the transmission image data generated by the transmission image data generator to the image display device.

An apparatus includes a buffer to store n lines of data divided into areas of column units. The apparatus obtains information of a column position corresponding to an end of an image to be printed with respect to a scanning direction of a print head. The apparatus reads data from the areas of the column units including the column position information and reduces the data to generate reduced data. The apparatus compresses the reduced data by using a pattern having n lines of data to generate first compressed data. Then, the apparatus compresses the first compressed data by k-bit units to generate second compressed data.

The present invention provides a user terminal. According to one aspect of the present invention, a user terminal includes a transmission control unit and a communication unit. The transmission control unit controls whether or not to permit the transmission of biological data obtained by measuring biological information of the user based on whether one of the one or more transmission conditions is satisfied. When the transmission of the biometric data is permitted, the communication unit transmits the biometric data.

An encoding apparatus comprises a dividing unit that divides RAW image data into a plurality of tiles, a generating unit that generates planes of a plurality of channels having mutually-different components for each of the tiles, a transforming unit that frequency-transforms the plane of each channel and generates sub-band data of a plurality of resolution levels, a controller that divides each of the plurality of sub-band data into the same number of segments to divide the sub-band data into a plurality of segments corresponding to the same regions, and determines first quantization parameters common for the plurality of sub-band data in each segment, a quantizing unit that, based on the determined first quantization parameters, quantizes each sub-band data, and an encoder that encodes a quantization result on a sub-band-by-sub-band basis.

The invention provides an optical disk that records a huge amount of still image data, realizes retrieval based on its recording time and reduces a data size of recording time information, and to provide an optical disk recorder and an optical disk reproducing device. In order to minimize a data quantity to manage a recording time of a still picture, N (N is an integer of 1 or over) sets of still images are grouped and a recording time of a still image recorded at first for each group and a recording time of a still image finally recorded by each group are recorded as management information.

A vehicle image data generation device includes: a section image data generation unit (11) that generates image data for each section as section image data based on image data generated by an in-vehicle camera; and a data transmission section (21) that generates section image data from the section image data The section image data generated by the section is sent to the server.

A storage device has a map database including at least two definite house numbers and at least one non-definite house number. The two determined house numbers are associated with measured position coordinates, which are obtained from an external server through measurement. The measured position coordinates of each determined door plate are stored in the storage device. The two definite house plates sandwich the non-determined house plate directly or indirectly along the road facing the non-determined house plate. Based on the measured position coordinates of the two definite house plates, when the error between the estimated position coordinates of the non-definite house plate calculated by proportional calculation and the measured position coordinates of the non-definite house plate is greater than a specified value, the The measured position coordinates of the indefinite house number are stored in the storage device, and when the error is smaller than a predetermined value, the measured position coordinates of the indefinite house number are not stored in the storage device.
