摘要:
An image signal processing unit comprising an image signal receiver, a first addition block, a compression block, and a determination block, is provided. The image signal receiver receives an image signal. The image signal is generated by an imaging device. The imaging device has a plurality of pixels generating pixel signal. A receiving surface of the imaging device is divided into a number of pixel blocks. A number of pixels are arranged in the pixel block. The first addition block generates high-sensitivity signal by adding up the pixel signals generated by some pixels arranged at a predetermined position in the pixel block. The compression block generates low-sensitivity signal by compressing the high-sensitivity signal so that the low-sensitivity signal is lower than the maximum signal level of the pixel signal. The determination block determines whether a signal level of the high-sensitivity signal is over the threshold level The low-sensitivity signal is output if the signal level of the high-sensitivity signal is over the threshold level. Alternatively, the high-sensitivity signal is output if the signal level of the high-sensitivity signal is under the threshold level.

A recording operation control device comprises a recording operation stop switch on a rear surface of a camera body of an electronic still camera. By fully depressing a shutter button, a CCD housed in the camera body is exposed so that image data is obtained and recorded in a PC card. If the recording operation stop switch is depressed before the recording operation of the image data is completed, the recording operation is stopped. Instead of depression of the recording operation stop switch, the shutter button may be depressed twice during a constant period of time so that the recording operation is stopped. Both the recording operation stop switch and the shutter button may be depressed to stop the recording operation.

A process for producing a colorant comprises the step of mixing a coloring material and a block copolymer in a flow channel of a microreactor to obtain a dispersion comprising a colorant as a dispersoid. The flow-mixing channel may have a cross-sectional area of not less than 0.5 mm2, and the ratio of the total cross-sectional areas of flow channels connected with the flow-mixing channel to the cross-sectional area of the flow-mixing channel ranges from 0.01 to 0.1, and a rectangular cross-section having a ratio of a flow channel depth to a flow channel width of not less than 0.5.

In the present invention, a reactor power control apparatus of a natural circulation reactor comprises a reactor pressure vessel which circulates cooling water using the density difference of the coolant inside, a feed water pipe which is connected to the reactor pressure vessel and supplies cooling water, a power control section which controls the reactor power using a control rod. The feed water pipe has an ultrasonic thermometer sensor. Driving of the control rod is controlled by the power control section based on the feed water temperature detected by the feed water thermometer. The reactor power control apparatus can detect the temperature of the feed water and perform drive control of the control rod preferentially, and obtain stable reactor power.

An image forming apparatus includes: a sheet tray; an image forming unit that forms an image on a recording sheet; a sheet transporting path that allows a transportation of the recording sheet fed from the sheet tray to the image forming unit; and a sheet detecting unit that detects a passage of a rear end, with respect to a direction in which the recording sheet is transported, of the recording sheet along the sheet transporting path. The transportation of the recording sheet is temporarily stopped at the time of, or after a predetermined time from when the rear end is detected by the sheet detecting unit. The transportation of the recording sheet is resumed on the basis of data on a size of the transported recording sheet and a timing of image formation by the image forming unit.

A focusing controlling device is for a camera having a photographing lens and an imaging surface. The focusing controlling device includes a focus adjuster that adjusts a focus position of the photographing lens based on field curvature data. The field curvature data indicates a field curvature ratio which is a ratio of a distance between an image point of light transmitted through the photographing lens and the imaging surface to a focal distance of the photographing lens, the field curvature data being set for a partial area of the imaging surface as an average value of the field curvature ratios for the partial area.

A digital single-lens reflex camera includes a lens unit and a camera body. The lens unit has a photographing lens and an identification data memory for storing identification data to identify the photographing lens. The camera body, to which the lens unit is detachably attached, has an imaging device which receives light transmitted through the photographing lens to generate an image corresponding to a subject, a lens data memory for storing lens data that indicates the shading characteristics of the photographing lens, a lens data reader that reads the lens data based on the identification data, and an image corrector that corrects an error in the image of the subject caused by shading, based on the lens data read by the lens data reader and imaging device data that indicates the shading characteristics of the imaging device.

An image signal processing unit which processes image signals corresponding to an image divided into a plurality of image-areas is provided. The image signal processing unit comprises a first detector, a second detector, and a blurring processor. The first detector detects a sharpness. The sharpness corresponds to how much of the image-area is in focus based on the image signals. The second detector detects an out-of-focus area from the image-areas when the sharpness of an out-of-focus area is out of a predetermined permissible range. The blurring processor carries out a blurring process for the out-of-focus area signal corresponding to the out-of-focus area.
