Abstract: Disclosed is a technique for accurately tracking a tracking target object. A disparity map image in which the disparity of each pixel of an object is shown is generated from a three-dimensional object image. A detection range is determined such that an object disposed on the front side of a pedestrian, which is a tracking target object, in the depth direction is excluded from the generated disparity map image. The pedestrian, which is a tracking target object, is detected in the determined detection range. In this way, it is possible to prevent a bike driver disposed on the front side of the pedestrian in the depth direction from being tracked.

Abstract: To solve an overlap between a part table and components automatically and adequately in a drawing using a CAD. In a part table creating method for creating a part table including a plurality of rows of CAD data, an overlap between the part table and other geometric elements is detected. When the overlap is detected, the height of the respective rows of the part table is reduced to H1. When the overlap between the part table and the other geometric elements still remains even when the respective rows of the part table is reduced to the height H1, the number of overlapped rows between the part table and the geometric element are obtained. The portion of the overlapped rows is separated and moved in the direction to avoid the overlap with the geometric elements to separate into an original part table and a destination part table.

Abstract: A digital zoom rate of two-dimensional images zoomed by a digital zoom unit is obtained. When the obtained digital zoom rate is larger than 100%, at least one of the digitally zoomed two-dimensional images is modified based on an enlarged amount of parallax to provide an amount of parallax between the digitally zoomed two-dimensional images equal to the enlarged amount of parallax. The enlarged amount of parallax is obtained by enlarging, at a moderated digital zoom rate, an amount of parallax between the two-dimensional images before being digitally zoomed, and the moderated digital zoom rate is obtained by moderating the digital zoom rate at a moderation rate, where the moderation rate increases as the zoom rate increases. Then, a display unit is caused to carry out three-dimensional display based on the modified two-dimensional images.

Abstract: A transmitter is provided which includes a transmitting circuit that does not require a high-performance low noise VCO restricting cost reduction thereof and that can reduce the number of parts without requiring an RF filter. A direct conversion that does not require a transmission VCO is applied to the transmitting circuit. In order to achieve noise reduction in a receiving band, low-pass filters are provided at IQ input sections of a modulator that converts IQ signals into RF signals. In comparison with a conventional transmitter using offset PLL, an external VCO required in addition to an RF integrated circuit, a power amplifier, and a front end circuit is reduced. Even in current transistor performance, by using a filter having rapid waveform characteristics such as a SAW more inexpensive than the VCO, or the like, it is possible to provide a GSM/GSM 1800/GSM1900 triple band transmitter.

Abstract: If a transmission oscillator is incorporated into a communication semiconductor integrated circuit, such as high a frequency IC, constituting a wireless communication system, a problem arises. The accuracy of control of the output power of a power amplifier is degraded. This degradation in accuracy is caused by coupling noise between the output pins of the transmission oscillator and an input pin for detection signals (feedback signals) associated with the output level of the power amplifier or crosstalk. To prevent this, a transmission oscillator of differential output configuration is incorporated into a high frequency IC and an impedance equivalent to the impedance connected with a regular output terminal or a dummy external terminal for outputting transmit signals in opposite phase is provided.
