    摘要: In an electronic still camera operable with a memory card or similar storage medium removably mounted thereto, a first controller causes, before a continuous shoot mode or similar mode operation begins, a memory card to develop attributes information particular to and stored in the card to a second controller. The attributes information include one representative of a storing speed available with the card. Then, the first controller selects a clock frequency of a clock signal which matches the storing speed and provides the card with a reference for operation. The first controller generates a clock signal having the clock frequency selected and sends it to the card together with image data representative of a scene. As a result, the image data are written to the card at a speed synchronous to the frequency of the clock signal.

    摘要: A solid-state imaging apparatus includes an image pick-up section in which photosensitive devices are arranged in, e.g., a honeycomb G square lattice, RB full-checker pattern due to shifted pixels. Regions void of the photosensitive devices are assumed to be virtual photosensitive devices. A signal processing section generates data for the virtual photosensitive devices by using the data of surrounding photosensitive devices while attaching importance to accurate color reproduction and horizontal and/or vertical resolution. As a result, the number of pixel data are increased in a square lattice arrangement. Therefore, high quality image signals are readily achievable with a smaller number of photosensitive devices than conventional with a conventional apparatus. Interpolation can be executed with the high quality signals to the limit of resolution with an adequate circuit scale. The honeycomb arrangement guarantees the required size of the individual pixel and thereby the sensitivity of the entire apparatus while increasing yield on a production line. False colors particular to a single photosensitive portion can be reduced by, e.g., uniform interpolation. Particularly, when a digital camera is constructed by using an imaging apparatus including optics operable with a silver halide sensitive type of film, false colors can be reduced without resorting to an optical low pass filter.

    摘要: In an electronic still camera, an imaging device outputs a high-resolution image signal representative of an optical image incident thereto via a lens. A movie processing section reduces, or thins, the high-resolution image signal to produce a corresponding low-resolution image signal on a real-time basis. The camera, therefore, implements the real-time display of a picture converted from the high-resolution image of a subject on a monitor.

    摘要: A normal AWB (auto white balance) correction value is calculated based on inputted image data. Further, a face area is identified from the inputted image data and a face AWB correction value is calculated based on image data in the face area. Then, first feature data and second feature data are extracted from the inputted image data and image data in the face area, respectively. A total AWB correction value is calculated in accordance with at least one of the face AWB correction value and the normal AWB correction value based on a comparison result of the first feature data and the second feature data. Thus, an erroneous correction can be prevented in an AWB correction using a face detection function.

    摘要: CCD-RAW data obtained by sensing the image of a subject is applied to a first noise reduction circuit via a offset correction circuit, a gain correction circuit, a linear matrix circuit and a gamma correction circuit. Uncorrelated noise is removed from the CCD-RAW data in the first noise reduction circuit. The CCD-RAW data is subjected to synchronization (color interpolation) in the synchronization processing circuit, and luminance data Y and color difference data C is generated by an RGB-YC conversion circuit. The generated luminance data Y and generated color difference data C is subjected to noise reduction processing on a per-frequency-component basis in the second noise reduction circuit. Suitable noise reduction processing conforming to the state of image data before and after synchronization processing is executed.
