  • Patent number: 8817133
    Abstract: In a digital camera 1, when a lagged-timing is recorded (Yes at Step S9), from the frame image picked up when the shutter is fully depressed, a frame image picked up at a timing equivalent to the lagged-timing is displayed (Step S10). When the cross-shaped key is operated before the SET key is operated, the displayed frame image is changed based on the operation (Step S12 and Step S13). Next, when the SET key is operated, the displayed frame image is recorded. In addition, a lag between the timing at which the recorded frame image is picked up and the timing at which the frame image picked up when the shutter is fully depressed is picked up is recorded (Step S15).

  • Patent number: 8760544
    Abstract: The radiation image pickup apparatus of this invention can obtain an accurate temperature characteristic of dark current noise, the dark current noise being caused by dark current flowing through an X-ray conversion layer, by obtaining dark image signals at varied times for accumulating in capacitors charge signals converted by an X-ray converting layer. Consequently, the noise due to the dark current can be removed with high accuracy by removing periodically acquired offset signals from X-ray detection signals acquired at a time of X-ray image pickup, and correcting variations of the dark current noise due to a difference in temperature between a time of offset signal acquisition and the time of X-ray image pickup, using the temperature characteristic of the dark current noise.

  • Patent number: 8743239
    Abstract: Disclosed are an image processing apparatus which effectively corrects, by a simple method, color crosstalk that is generated in a captured image by light obliquely entering an image sensor, and a control method thereof. A white-detection area used in white balance processing for a captured image signal is set in accordance with an aperture value used in image capturing. The degree of color crosstalk depends on an aperture value used in image capturing, and the spectral sensitivity characteristic of the image sensor changes depending on the degree of color crosstalk. By setting a white-detection range to correct a change of the spectral sensitivity characteristic depending on the aperture value, color crosstalk can be simply, effectively corrected.

  • Patent number: 8619162
    Abstract: Whether a pixel of interest contained in applied image data exhibits color bleed (a false color or purple fringe) is determined. If the pixel of interest is determined to exhibit color bleed, a direction along which luminance is monotonically decreasing in the vicinity of the pixel of interest is discriminated using the pixel of interest as a starting point. A search is performed in the direction of monotonically decreasing luminance to find a pixel where the monotonic decrease in luminance ends. The found pixel where the monotonic decrease in luminance ends is decided upon as a target pixel and a correction value for causing the color of the pixel of interest to match the color of the target pixel is calculated. The color of the pixel of interest is corrected using the calculated color correction value.
