  • Patent number: 7184078
    Abstract: A digital camera is provided with a plurality of image-pickup modes to carry out an optimal controlling process in accordance with an image-pickup scene. With respect to mode selection settings, a switching can be made between a manual selection setting in which the user manually selects an image-pickup mode and an automatic selection setting which automatically discriminates each image-pickup scene, and selects a suitable image-pickup mode. In the case of the automatic selection setting in the mode selection setting, a limited value in comparison with a parameter value relating to the image quality set at the time of the manual selection setting is set as the parameter. As a result, even in the case of a misdiscrimination in an image-pickup scene, it is possible to provide a flawless image as the resulting image, and consequently to prevent serious degradation in the image quality.

  • Publication number: 20060055991
    Abstract: A digital camera (10a) is placed in any of three photographing modes labeled a “narrow mode”, a “normal mode”, and a “wide mode”. An operating point setter (903) variably sets an operating point of a CCD (26) defining a brightness range of a subject which falls within a dynamic range of an image sensor, based on a photographing mode as set. A LUT setter (902) variably sets a gradation correction LUT which is a concrete representation of gradation correction characteristics in gradation correction performed by a ? correction circuit (55) (characteristics in ? correction), based on the photographing mode as set. The operating point set by the operating point setter (903) and the gradation correction LUT set by the LUT setter (902) are changed in synchronism with each other in accordance with change in the photographing mode.

  • Publication number: 20060050954
    Abstract: In an image processing apparatus, raw image data can be read and a tone-converted image obtained by performing ? correction on the raw image data is displayed in an image display area on a display screen. On the image display area, an arbitrary point can be designated by the user. In the case where a first point and a second point are designated, exposure amounts are calculated on the basis of the raw image data, and the exposure amount difference is displayed on an exposure amount difference display area. As a result, the user can grasp the exposure amount difference between the designated points while visually recognizing the tone-converted image. Thus, a proper index used at the time of performing an image process such as ? correction can be obtained.

  • Publication number: 20060001748
    Abstract: An image sensing apparatus is provided with an image sensor having a photoelectric conversion characteristic comprised of a linear characteristic area where an electrical signal is outputted after being linearly converted in relation to an amount of an incident light and a logarithmic characteristic area where the electrical signal is outputted after being logarithmically converted in relation to the amount of the incident light. An evaluation value detector of a signal processing unit detects evaluation values concerning an image sensing control from each of the linear characteristic area and the logarithmic characteristic area upon picking up an image of a subject based on pieces of subject luminance information in the respective areas. A central control unit (image sensing controller) carries out the image sensing control based on the evaluation values corresponding to the respective areas detected by the evaluation value detector.
