  • Patent number: 7871471
    Abstract: It is intended to prevent an increase in the quantity of particles on a test-piece substrate having undergone processing executed at a low temperature equal to or lower than 0° C. In an inspection method adopted when inspecting the state inside a processing chamber by measuring the quantity of particles on a test-piece substrate, i.e., a test-piece wafer, the test-piece wafer W having undergone a specific type of test processing inside the processing chamber is carried out into a transfer chamber via a loadlock chamber after holding it in the loadlock chamber over a predetermined length of time while delivering a dried inert gas into the loadlock chamber. The predetermined length of time is set to a value at which the increase in the quantity of particles on the test-piece wafer can be kept down at least within an acceptable range.

  • Patent number: 7835639
    Abstract: When the mode is set to a strobe consecutive shooting mode, an imaging apparatus sets the mode to a pixel addition drive mode for reading out image data using pixel addition drive (S7), performs metering operation using preliminary flashing (S8) and calculates an appropriate amount of flashing on the basis of the metering operation (S9). Next, the imaging apparatus judges whether or not it is possible to flash three times consecutively with the calculated amount of flashing (S10). If it is judged that it is not possible to flash three times consecutively with the calculated amount of flashing (NO in S10), the imaging apparatus limits the amount of flashing to the largest amount of flashing within the range of amounts of flashing with which flashing of strobe light three times consecutively is possible (S11), and performs strobe consecutive shooting with the limited amount of flashing (S13 to S17).

  • Patent number: 7825955
    Abstract: Immediately before regular image pickup, a reference image is taken through exposure control by center-weighted photometry. A histogram indicative of a luminance distribution of all pixels is generated on the basis of luminance information of the reference image. Then, a luminance point in the histogram where the accumulated number of pixels from the high-luminance side is equal to a half of the total number of pixels is obtained, and a difference is calculated between the luminance point and a luminance point (“118”) when the brightness is uniform in the reference image. At the time of regular image pickup, proper exposure determined in response to the brightness of the subject when the reference image is taken is compensated with the previously calculated difference, and exposure control for the compensated proper exposure is performed.

  • Patent number: 7746405
    Abstract: There is provided an illumination apparatus used for imaging a moving picture made up of a plurality of frames, and for irradiating an auxiliary light from a light source constituted by one or a plurality of LEDs onto a photo-object. The one or plurality of LEDs are duty-driven by a duty ratio smaller than 100% during an imaging period (during a period for exposing a CCD) of a frame period. The heat releasing effect and the light emitting efficiency can be improved as compared to a case where the LEDs are successively turned on during an imaging period. As a result, the light emitting intensity at the time the light emitting diodes are turned on can be heightened with the amount of consumed electricity unchanged, and the light emitting efficiency of the light emitting diodes can be improved.

  • Patent number: 7710458
    Abstract: When a hand shake reducing mode has been set for shooting a subject, an exposure is controlled in accordance with a program diagram (solid line) B for the shake reducing mode, which is different from a program diagram (broken line) A for a normal mode. In a state where a shutter speed is set to less than “ 1/80”, two-pixel addition and/or four-pixel addition is executed on an imaging signal to amplify subject luminance, raising ISO sensitivity. A shutter speed set to fall in a high speed range reduces deterioration in image quality due to hand shake and/or subject movement during a shooting operation.

  • Patent number: 7643083
    Abstract: The data of each pixel of a CCD, acquired from double pre-emissions performed in accordance with a shutter operation, is estimated to determine appropriate luminous energy for actual photography. Specifically, in each frame between the shutter operation and emission for actual photography, a CCD is driven so that only the data of the pixels corresponding to an estimation area is transferred, and the data of the other pixels is destroyed. The estimation area is included in the image pickup area of the CCD and used to determine the appropriate luminous energy. As a result, the time required to transfer pixel data unnecessary for estimation is omitted, thereby reducing the total processing time ranging from the pre-emissions to the emission for actual photography, and realizing prompt actual photography with appropriate luminous energy.

  • Publication number: 20090185070
    Abstract: In a digital camera 1, in an automatic shooting stand-by state, when judged at Step S26 that an automatic shooting condition has been satisfied (N at Step S26), whether or not to issue an AE re-processing command is judged. In other words, whether or not the current shooting condition is similar to a condition where an automatic shooting condition is satisfied is judged. When judged to issue the AE re-processing command, exposure tracking in an aperture-priority mode is performed (S28), and shooting exposure conditions excluding the aperture value for still-image shooting in the aperture-priority mode are determined. Then, the storage is updated (Step 29), and the process returns to Step S26. When judged at Step S26 that an automatic shooting condition has been satisfied (Y at Step S26), record processing for still-image shooting is performed with the updated shooting exposure conditions without changing the aperture value (Step S30).
