Inventor: KITAJIMA TATSUTOSHI
IPC: H04N1/00
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera that can photograph a moving image and a static image, store the static image and output the moving image and the static image in a form proper to a video conference system. SOLUTION: The digital camera has normal functions for obtaining a moving image by consecutive shots, photographing a static image through release of a shutter and store the pictures into an image memory, and further has other means such as a compression/multiplexing section that compresses each frame of the moving image in a prescribed operating mode to provide compressed moving image data, a communication interface that provides an output of the compressed moving image externally in a proper format, and an image selection means with which a user selects an image. When a user selects an image, the compression/multiplexing section outputs the selected image in place of the compressed moving image data. The selected image is not compressed or compressed at a compression rate lower in general than that of the moving image.  Compression coding and pixel interleaving are used for compressing the moving image. Gray scaling or binary processing is employed for compressing the selected image, and the image is selected by the operation of a release button during photographing a moving image or by selecting a static image stored in the image memory or an external memory, such as a memory card.

IPC: B60K23/08
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction of an actuator caused by a trouble of a position detecting switch.

Abstract: PROBLEM TO BE SOLVED: To provide a channel estimate device that does not prolong the processing time without deteriorating the reception performance even in the case of an initial state such as start of communication or in the case of switching of a delay detection interval. SOLUTION: A frequency offset detection section 2041 of a phase rotation detection circuit 204 detects a frequency offset by using an inverse spread signal of a received signal and an fD detection section 2042 detects an fD (a maximum Doppler frequency due to fading fluctuations) by using the frequency offset. A detection monitor 206 monitors the frequency offset detection period or the frequency offset detection/fD detection period. The detection monitor circuit 206 applies switching control to a switch 210 on the basis of the monitor result. For this period, a statistic processing result (tentative fD) is set as an initial value of the fD. A weight coefficient calculation circuit 209 calculates a weight coefficient α by using the fD detection result or the statistic processing result and outputs the weight coefficient α to a weight adder circuit 203.  Then the weight adder circuit 203 uses the weight coefficient α to conduct the WMSA(Weighted Multi-Symbol Averaging) thereby outputting a channel estimate value.
