摘要： An object of this invention is to perform, for a photographed image, image processing which reflects the intention of the user without photographing again. In order to achieve this object, photographing data from an image sensor is temporarily stored in a memory, and an image of the photographing data as a result of digital development processing is displayed. When it is determined from the displayed image that the parameters of various image processes in digital development processing are not proper for the photographed image, the parameter settings are corrected again. Then, operation of reading out photographing data from the memory and performing digital development processing again is executed a necessary number of times. When an image quality intended by the photographer is obtained, the photographing data is recorded on a recording medium.

摘要： A method for reading out an image signal includes providing at least two photosensitive regions and providing at least two transfer gates respectively associated with each photosensitive region. The method also includes providing a common charge-to-voltage conversion region electrically connected to the transfer gates and providing a reset mechanism that resets the common charge-to-voltage conversion region. After transferring charge from at least one of the photo-sensitive regions, all the transfer gates are disabled at a first time. The method further includes enabling at least one transfer gate at a subsequent second time and transferring charge from at least one of the photosensitive regions at a subsequent third time while the at least one transfer gate from the second time remains enabled.

摘要： A parameter of a digital camera or other digital image acquisition device is adjusted to maintain the resulting digital signal within a range carried by a digital processing path that carries a limited number of bits. The magnitude of the parameter is then also used to represent the image. Examples of the parameter include analog signal gain and exposure time. This is a cost effective way to increase the dynamic range of a digital camera, instead of increasing the width of its digital processing path. The digital data may be processed to obtain either tone mapped images, which are compatible with current cameras and other equipment, or to obtain images with a greater dynamic range for use with suitable displays and the like.

摘要： The invention refers to a flash light compensation system and corresponding method for digital camera systems, wherein a luminance compensation is carried out on an image of a scene (3) picked-up by an image sensor (1), on the basis of a respective intensity field measured by a plurality of sensors (4, 5), when the scene is illuminated by flash light emitted by a flash device (2). Depending upon the output signals of the plurality of sensors a depth field of the scene is estimated, and this estimation provides a basis for the luminance adjustment on the scene picked up as an image while illuminated by the flash device. The system and method is suitable for effectively reducing the problem of unevenly distributed lighting on a picked-up image of the scene.

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.
