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： When a motion image is to be compressed, the present invention divides a high-resolution still image into image segments to perform a motion image encoding process on each image segment. In this instance, the importance of each image segment and the relativity of each image segment with another image segment are computed. The image segments are then aligned in the order of importance to determine a picture type for motion image encoding in accordance with the computed relativity. Encoding is performed in accordance with a determined encoding sequence and picture type. Further, the rate control bit allocation amount for motion image encoding is increased for highly important image segments. Therefore, the present invention makes it possible to exhibit a high overall image compression efficiency while avoiding image quality deterioration in an important portion of a still image by using a motion image compression technology for still image compression.

摘要： A stereoscopic imaging system includes a stereoscopic imaging apparatus having a plurality of imaging modules to pick up an image and an imaging sync control module to arithmetically process the video signals output from the plurality of the imaging modules for the stereoscopic imaging operation. In the case where the imaging modules control the exposure using an electronic shutter function and come to have different timing of the center of gravity of the exposure period, an imaging sync control module sets the plurality of the imaging modules at the same timing of the center of gravity of the exposure period by displacing the phase of the timing of the center of gravity of the exposure period of the imaging modules thereby to prevent the image processing capability of the stereoscopic imaging operation from being reduced.

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.
