Imaging apparatus

Problems, such as unevenness of exposure, caused by the difference in speed between a first curtain and a second curtain and a positional shift between the curtains (the occurrence of an edge darkening phenomenon) can be prevented. In addition, power consumption is reduced. When the shutter speed is set to be low by exposure control means, the exposure start operation is performed using an electronic focal plane shutter function of an image sensor (an electronic focal plane shutter is used for the first curtain), and an exposure end operation is performed by a mechanical focal plane shutter. In contrast, when the shutter speed is set to be high by the exposure control means, the exposure start operation and the exposure end operation are performed using the mechanical focal plane shutter (the mechanical focal plane shutter is used for the first curtain).

The drive arrangement including at least one adjustable component for driving one of the crop feed arrangement or chopper means at a variable speed thereby changing the length into which the harvested crop is cut. A control device is connected to the adjustable component and to a crop parameter sensor to measure at least one parameter of the crop being harvested. The control device automatically controls the adjustable component such that the length into which crop is cut by the chopper mechanism is a function of the sensed crop parameter.

Optical shutter for miniature cameras

The invention relates to a shutter for an optical imaging system, e.g. a digital camera. The shutter comprises an interface between a transparent body and a capillary space. Light rays introduced to the active area of the interface are reflected by total internal reflection when the capillary space is filled with a gas. The light rays are transmitted through the interface when the capillary space is rapidly filled with a liquid. Thus, the light rays are either absorbed or reflected towards an image sensor, depending on the state of the shutter. The liquid is delivered to the capillary space through at least one duct which is positioned opposite the active area.

Solid-state image sensing apparatus with a relative positional light shift

Light from an object is incident to an image sensing device and converted into an image signal. The image sensing device is exposed to the light by a shutter, provided between the object and the solid-state image sensing device, for a first exposure period and a second exposure period that directly follows the first exposure period. The first and the second periods are the same length in time. Each exposure period for exposing the solid-state image sensing device to the light corresponds to one frame or one filed of the object. A passage of the light that has passed the shutter and incident to the solid-state image sensing device is shifted in a predetermined direction with respect to the solid-state image sensing device at least in the second exposure period. Image signals converted for the first and the second exposure periods are combined to generate a composite image signal.

Method for capturing violation of regulations

The invention discloses a method for capturing violation of regulations. The method is applied to a traffic management system to capture the violation of the regulations. The type of the violation of the regulations is chosen on a client-side, a central server is started through a capturing instruction to carry out picture recording of the violation of the regulations, front-end equipment is started to carry out capturing, and the pictures of the violation of the regulations are uploaded to an analyzing server to be processed. After the analyzing server processes the pictures of the violation of the regulations, the pictures of the violation of the regulations are related to incident records and are reported to the central server to stop picture recording, and the video of the violation of the regulations is related to the incident records. Through the method for capturing the violation of the regulations, the front-end equipment is utilized to carry out capturing, the pictures are clearer, meanwhile, occupied network bandwidth is small, and one client-side can analyze the truth flow of more front-end equipment.

Digital still camera and method of controlling same

In order to halt smear sweep-out in a case where the effects of smear charge are considered minor, it is determined whether the shutter is a high-speed shutter when a shutter-release button is pressed. If the shutter is not the high-speed shutter, a CCD is exposed and signal charge accumulates in the photodiodes of the CCD. Smear charge is swept out before the signal charge is shifted from the photodiodes to vertical transfer lines. The signal charge is thenceforth transferred to the vertical transfer lines and a video signal is output from the CCD. In the case of the high-speed shutter, smear sweep-out is halted and charge is shifted from the photodiodes to the vertical transfer lines.
