  • Patent number: 7512267
    Abstract: An image signal generated by a CCD image sensor is processed by the block-generating section 28 provided in an image-signal processing section 25. A class tap and a prediction tap are thereby extracted. The class tap is output to an ADRC process section 29, and the prediction tap is output to an adaptation process section 31. The ADRC process section 29 performs an ADRC process on the input image signal, generating characteristic data. A classification process section 30 generates a class code corresponding to the characteristic data thus generated and supplies the same to an adaptation process section 31. The adaptation process section 31 reads, from a coefficient memory 32, the set of prediction coefficients which corresponds to the class code. The set of prediction coefficients and the prediction tap are applied, thereby generating all color signals, i.e., R, G and B signals, at the positions of the pixels which are to be processed.

    Abstract: An image taking apparatus installed with an image blur correction unit for correcting image blur by combining images, so image taking time in a case of continuous shooting of the images is prevented from being long and operations are carried out in a manner in which a photographer does not feel disorder. Combination of a second frame and a third frame that are taken with split-exposure is started from a frame that is prior by two frames in terms of time. Thereby the number of times of split-exposure operations necessary to obtain three combined images is eight, so the image taking time is made to be shorter compared to a case of simple continuous combination of the images. Further, the three combined images produced in this way include a portion overlapped in terms of time, however, the combined images are images different from one another that are continuous in terms of time, so the photographer does not feel disorder as long as setting is made as to how many frames are shifted for combination.

  • Patent number: 7292280
    Abstract: Maximum and minimum aperture sizes are regulated with regard to a diaphragm in order to secure predetermined optical capability in an optical unit which includes a taking lens and the diaphragm. In a normal taking, the diaphragm is used within a normal taking range from the maximum to the minimum aperture sizes. In the present invention, an aperture size which is larger than the maximum size and a size which is smaller than the minimum size (extra aperture size or extra small size) are respectively set at outside the range that secures the capability. The aperture sizes of the diaphragm at outside the specified range are used at least for one of the following: automatic exposure (AE) adjustment, auto focus (AF) adjustment, electronic zoom, displaying a moving image, taking for recording the moving image, and taking under a low resolution by thinning out pixels.

  • Patent number: 7268806
    Abstract: An exposure control device accurately adjusts exposure even when photographing the operator. An area-integration circuit divides a photographed image into a central area and a peripheral area to integrate corresponding video signals for the respective areas. When the operator of a notebook personal computer sets the direction of an image pickup unit to photograph himself a control microcomputer multiplies the respective areas by weights so that the weight of the central area is larger than the others, and then it adds the two integration results. The control microcomputer sets the addition result as exposure information, compares the exposure level indicated by the information with a reference level, controls an electronic shutter of an image pickup device and a gain of an amplifier circuit so that the exposure level coincides with the reference level, and adjusts the exposure of a video camera to a proper level.

  • Patent number: 7262794
    Abstract: A method of making a digital photograph composed of a moving water element and still element by applying a known computer image processing system, and a digital photograph made by this method, involves taking a basic photograph indicating a realistic image of still elements and photographs taken by applying a series of shutter speeds. A series of digital images corresponding to the above-mentioned photographs are indicated on a monitor of the processing system, and an image indicating a realistic image of the moving water element is selected from the series of digital images. A color matching operation is them applied to the selected digital image whereby a final digital image having a still element substantially color matched to that of the basic photograph and a realistic image of a moving water element is indicated on the monitor, and thereafter a realistic digital photograph is printed based upon the final image.

  • Patent number: 7251057
    Abstract: A digital camera includes a CCD imager. When a display-use UYV signal is generated on the basis of an RGB signal of an object image photographed by the CCD imager, a CPU detects a color saturation degree of the RGB signal and reduces dynamic range of a U signal and a V signal on the basis of the detected color saturation degree. Thus, a color on the basis of the U signal and the V signal is aboundingly included within a color reproducing range of a monitor.

  • Patent number: 7209166
    Abstract: Wide dynamic range operation is used to write a signal in a freeze-frame pixel into the memory twice, first after short integration and then after long integration. The wide dynamic range operation allows the intra-scene dynamic range of images to be extended by combining the image taken with a short exposure time with the image taken with a long exposure time. A freeze-frame pixel is based on voltage sharing between the photodetector PD and the analog memory. Thus, with wide dynamic range operation, the resulting voltage in the memory may be a linear superposition of the two signals representing a bright and a dark image after two operations of sampling.

    Abstract: An OB level difference is calculated from the luminance signal levels of at least two frames which are exposed for proper exposure time and for exposure time different from the proper exposure time, and the OB level difference is corrected in an input step of a signal processing circuit. Calculation of the OB level difference is performed regularly from immediately after power on of the equipment, the OB level difference obtained in each frame is multiplied, and a value obtained by dividing the multiplied OB level difference by the number of sampled frames is designated as a correction value.

  • Patent number: 7176962
    Abstract: First image data and second image data are generated by capturing a subject image at a CCD. The first image data captured over a first exposure time manifest a relatively small extent of image blur. The second image data are captured over a second exposure time set longer than the first exposure time. A spatial frequency analysis is implemented on the first image data and the second image data to calculate the amplitude ratio and the phase difference of the high-frequency components in the two sets of image data. Based upon the amplitude ratio and the phase difference of the high-frequency components thus calculated, the spatial frequency component of the second image data is corrected to generate third image data in which any image blur has been corrected.

  • Patent number: 7161629
    Abstract: In an electronic camera, an exposure amount S ( 1/2000 sec.), an exposure amount M ( 1/250 sec.) and an exposure amount L ( 1/30 sec.) are set in vertically synchronous signal timing directly before the fourth frame, the fifth frame, and the sixth frame. In the frame directly following that setting, exposure is performed corresponding to that exposure amount. The signal levels obtained from the three exposure amounts are compared in the eighth frame, and an added value ? is added to the shutter time in which the signal level obtained is closest to the optimum signal level. This time is set in vertically synchronous signal timing directly before the ninth frame. In the ninth frame, exposure is performed corresponding to this setting. In the tenth frame, the signal is readout according to this exposure. In the eleventh frame, the signal calculation is performed. The processing is repeated in the same way thereafter and the optimum exposure amount is determined.
