摘要： The autofocus function included in general digital cameras and video cameras cannot set the camera to an in-focus state for a scene including a point light source depending on cases. This difficulty is removed by an image signal processing device including an area setting unit to set an area as a target area to calculate a focus evaluation value, a detection unit to judge presence or absence of a point light source in the area set as a target area, and a calculation unit to identify, by use of information obtained from the detection unit, an area in which a point light source exists and to calculate a focus evaluation value by removing the identified area from the target area. Once the detection unit detects a point light source, it conducts the operation only after a predetermined period of time.

摘要： Considering the locations of a self-vehicle and other vehicles changing from moment to moment, an image signal is chosen in relation to the location, orientation, viewing angle, and moving speed of a camera mounted on each vehicle, and information on a region to be a driver's blind spot is provided in real time by means of images and voice. When there is the other vehicles whose camera meets requirements such as the location, orientation, viewing angle, and moving speed for photographing a region to be the self-vehicle's blind spot, it is possible to provide information on the blind spot by the image picked up by the camera. However, since the other vehicle's location also changes with a lapse of time, it is not possible to keep photographing the blind spot with the same camera. Therefore, the image of the driver's blind spot is obtained in real time by constantly detecting the location, orientation, viewing angle, and moving speed of cameras mounted on the other vehicles running near the self-vehicle, choosing dynamically a camera capable of photographing the region to be the self-vehicle's blind spot, and switching image signals in succession.

摘要： A picture-data compression system for compressing inputted multiple picture data includes a storage device that stores the multiple picture data; a selection controller that writes the multiple picture data into the storage device and reads the multiple picture data from the storage device; a pixel-number converter that converts the number of pixels of the picture data read from the storage device; and an inter-picture predictive coding unit that codes the picture data whose number of pixels is converted by the pixel-number converter by inter-picture predictive coding. The selection controller reads the picture data written to the storage device at a period of 1/n (positive integer) times the frame period or field period of the picture data. The pixel-number converter converts the number of pixels of the picture data read from the storage device to 1/m times (positive integer) the original.
