Abstract: The present disclosure provides a detection system, which includes an image sensor, a lens device, and a processor. The image sensor is configured to take a first picture of a foreground object and a background object. The lens device is attached to the image sensor and configured to allow the foreground object to form a clear image on the first picture and the background object to form a blurred image on the first picture. The processor is configured to determine the image of the foreground object by analyzing the sharpness of the images of the first pictures.

Abstract: Optical equipment which can prevent image blurring and enable a lens to be stopped in a position requiring low power consumption is provided. The optical equipment includes a lens driving unit supplied with electric power from a camera body to drive a focusing lens. The equipment further includes an aperture driving unit for driving an aperture and a drive control unit that positions s the focusing lens to minimize low power consumption and controls the aperture driving unit during opening of the aperture so that the focal position of the focusing lens falls within a focal depth. In this way, a lens position-control unit for controlling an AF motor can stop the lens in a position that does not cause image blur and reduces power consumption.

Abstract: A camera system has an imaging optical system, an imaging component, a liquid crystal monitor, an aperture setting component, and an image display controller. The liquid crystal monitor has a first display region and a second display region. The aperture setting component adjusts the aperture in a specific period so that the actual aperture value will be a preset value. The image display controller displays, in the first display region, a reference image acquired by the imaging component under conditions in which the aperture value is the preset value, and displays, in the second display region, a comparative image acquired by the imaging component at a different timing from that of the reference image.

Abstract: To increase the depth of field of an optical system, an inversion of the chromatism is produced. This accommodates the fact that, in natural light, users prefer, for their photographs, taking long distance shots outdoors, where the illuminant is mostly composed of blue, and short-distance shots indoors, where the illuminant is mostly composed of red. While optical devices naturally focus the blue components at a shorter distance than the red components, which is unfavorable, with an inversion of the chromatism, a focus more in keeping with what is required is restored.

Abstract translation: 为了增加光学系统的景深，产生色差反转。 这适应了这样一个事实：在自然光线下，用户喜欢他们的照片，在户外长时间拍摄照明物，其中主要由蓝色构成，短距离拍摄在室内，其中发光体主要由红色构成。 虽然光学装置自然地将蓝色部件聚焦在比红色分量更短的距离处，这是不利的，但是随着色度的反转，更多地保持与所需要的对应的焦点。

Abstract: A method and system are described for providing background blurring when capturing an image using an image capture device. According to one aspect, input is received for initiating an image capture process for capturing an image of a subject at an image capture device. A depth of field for capturing the image of the subject in a half of the depth of field furthest from the image capture device is automatically determined. The image is captured using the automatically adjusted depth of field to provide background blurring in the captured image.
