摘要： A dust detection system, comprising a receiver, a dust extraction block, a memory and an image correction block, is provided. The receiver receives an image signal. The dust extraction block generates a dust image signal on the basis of the image signal. The memory stores an intrinsic-flaw image signal corresponding to an intrinsic-flaw image including sub-images of dust that the dust extraction block extracts in initializing. The image correction block generates a corrected dust-image signal on the basis of the intrinsic-flaw image signal and a normal dust-image signal. The normal dust-image signal corresponds to a normal dust image including sub-image of dust that the dust extraction block extracts after initializing. The corrected dust image is the normal dust image that sub-images of dust in the intrinsic-flaw image are deleted from.

摘要： An image sensor driving unit, comprising a first controller, a second controller and a third controller, is provided. The image sensor driving unit drives an image sensor to carry out the capture of an image. The capture is carried out by ordering pixels to generate signal charges and the charge-transfer channel to transfer the signal charges. The first controller orders the image sensor to carry out a rapid discharge operation before the charge-transfer channel transfers the signal charges. The second controller controls the first controller to order the image sensor to carry out the rapid discharge operation when light is made incident for capture after the first capture with the image sensor operating in continuous photographing mode. The third controller decreases the discharge number for capture after the first capture.

摘要： An apparatus for recording image data has an encoding processor that compresses original image data (for example, RAW data), having a plurality of pixels, in accordance with a lossless compression coding; and a recording processor that records the compressed image data or the original image data into a memory. If the size of the compressed image data is larger than that of the original image data, the recording processor records the original image data into the memory without carrying out a compression process.

摘要： A camera has a contrast detector that successively detects contrast data of an object image that is formed on a light-receiving surface of an image sensor, and a focus detector that detects a focused situation on the basis of the contrast data. The camera has, further, a focus adjuster that focuses the object by driving a photographing optical system. When the object is out of focus, the focus adjuster drives the photographing optical system so as to shift the image-formed surface forward and backward. Then, the focus detector detects standard contrast data corresponding to a position before shifting the image-formed surface, forward contrast data corresponding to the forward position, and backward contrast data corresponding to the backward position. The focus adjuster shifts the image-formed surface toward a direction of increase of the contrast data that is obtained from the standard contrast data, the forward contrast data, and the backward contrast data.

摘要： An image sensor driving unit, comprising a signal generator and a controller, is provided. The charge-transfer channel transfers the signal charges at a speed according to the frequency of a transfer signal. The signal generator transmits the first discharge signal and the second discharge signal to the image sensor. The first and second discharge signals are the transfer signals for the charge-transfer channel to carry out rapid discharge. The frequency of the second discharge signal is greater than that of the first discharge signal. The controller orders the signal generator to generate the first discharge signal during an overlap period when a driving period is at least partially overlapped with a discharge period. The controller orders the signal generator to generate the second discharge signal when the driving period is not overlapping with the discharge period.

摘要： A imaging-device driving unit, comprising a signal generator, a detector, and a controller, is provided. The imaging-device driving unit drives an imaging device that has a charge-transfer channel. The charge-transfer channel transfers the signal charges at a speed according to a frequency of a channel-driving signal. The signal generator generates one among a normal transfer signal, and a first and second discharge signals. The first discharge signal is the channel-driving signal whose frequency is determined for discharging an electrical charge remaining in the charge-transfer channel and greater than that of the normal transfer signal. The detector detects a remaining power. The controller orders the signal generator to generate the first discharge signal if the electrical charges remaining in the charge-transfer channel should be discharged and the remaining power is less than a threshold.

摘要： A camera has a contrast detector that successively detects contrast data of an object image that is formed on a light-receiving surface of an image sensor, and a focus detector that successively calculates a difference value between currently detected contrast data and previously detected contrast data, and that detects a focused situation on the basis of the difference value and the detected contrast data. The camera further has a focus adjuster that drives a photographing optical system so as continuously to shift an image-formed surface from a given position along an optical axis. While the photographing optical system is driven, the focus detector determines whether the image-formed surface surpasses a focused-position corresponding to a position of the light-receiving surface, on the basis of a decreasing-amount of the difference value.

摘要： A focusing device includes a distance measurer, a focus adjuster, a focusing judge, and an area display. The focus adjuster measures area subject distances that are distances to a plurality of distance-measuring areas on a subject. The focus adjuster adjusts a focus to focus on the distance-measuring area. The focusing judge determines whether or not the distance-measuring area is a focus-adjustable area for which the focus adjuster can adjust a focus, based on the area subject distance. The area display displays the focus-adjustable area, such that one of the focus-adjustable areas for which the focus adjuster adjusts a focus can be selected as a selected area, based on the area subject distance.
