    摘要: The specification and drawings present a new method, apparatus and software product for enhancing a dynamic range of an image with a multi-exposure pixel pattern taken by an image sensor of a camera for one or more color channels, wherein a plurality of groups of pixels of the image sensor have different exposure times (e.g., pre-selected or adjusted by a user through a user interface using a viewfinder feedback, or adjusted by a user through a user interface after taking and storing RAW image, etc.). Processing of the captured image for constructing an enhanced image of the image for each of the one or more color channels can be performed using weighted combination of exposure times of pixels having different pre-selected exposure times according to a predetermined criterion.

    摘要: A wide dynamic range image sensor method combines the response of high-gain sensing cells and low-gain sensing cells with better linearity than the prior art. A search is made in successive central regions within the response curve of the high-gain and low-gain cells to find a highest slope linear fit. This highest slope and the corresponding offset are used in mixing the high-gain and low-gain responses to achieve a wide dynamic range.

    摘要: An imaging apparatus includes a solid-state imaging device and an imaging device driver. The imaging device includes first pixels and second pixels. The first pixels execute an imaging operation for a long exposure time. The second pixels execute an imaging operation for a short exposure time which overlaps with a part of the long exposure time. The first and second pixels are mixedly arranged in a two dimensional array. Plural different drive controlling modes each controlling operation timings of start and end of exposure of the first pixels and operation timings of start and end of exposure of the second pixels are prepared in advance. The imaging device driver selects one of the drive controlling modes in accordance with a shooting condition under which an object image is taken and drives the solid-state imaging device in accordance with the selected mode.

    摘要: A CCD of a digital camera has high sensitive main pixels for depicting gradations in low and middle brightness portions of a subject, and low sensitive sub pixels for depicting gradations in high brightness portions of the subject. Main pixel image signals from the main pixels have a larger signal level than sub pixel image signals from the sub pixels. The main pixel image signals are attenuated by an attenuator to have the same signal level as the sub pixel image signals. The attenuated main pixel image signals and the sub pixel image signals are amplified by an amplifier with the same gain. The amplified main and sub pixel image signals are digitalized and composed to generate composite image data.

    摘要: An image sensor generates an image signal with a differential response to image light. The image sensor has an array of photosites divided into standard photosites and non-standard photosites. A limiter provides the standard photosites with a predetermined standard response to a light exposure and the non-standard photosites with a predetermined slower response to the same light exposure. The standard photosites and nonstandard photosites both sparsely sample the array in a predetermined pattern.
