摘要： Whether purple fringing (PF) has occurred is determined for every pixel of interest P(i,j) (step 41). The RGB ratio of a purple-fringed pixel P(i,j) at which PF has been determined and the RGB ratio of a PF convergence pixel P(m,n) spaced N pixels away from the purple-fringed pixel P(i,j) within a zone in the proximity of the purple-fringed pixel P(i,j) are calculated (steps 42, 43). A correction coefficient Rev (i,j) that causes the RGB ratio of the purple-fringed pixel P(i,j) to approach the RGB ratio of the PF convergence pixel P(m,n) is calculated (step 44). The purple-fringed pixel P(i,j) is color-corrected using the correction coefficient Rev (i,j) calculated.Purple fringing is made inconspicuous by changing the color of image portions at which purple fringing has occurred.

摘要： When a shutter release button of an image capturing apparatus is half pressed, an exposure time t is determined by a normal AE function. Then, if a shutter release button is fully pressed, an image is captured with the exposure time t, and the captured image is stored in a frame memory. At the same time, a color-coding circuit color-codes the captured image according to luminance thresholds, and the color-coded image is displayed on an LCD. If a user selects a color of an area equivalent to a main subject with reference to the color-coded image, a dynamic range, gamma characteristics, and the like of the image are determined so that the area in the selected color can have a correct luminance. The image is corrected accordingly, and image data acquired by the correction is stored in a recording part.
摘要翻译：当按下图像拍摄装置的快门释放按钮时，曝光时间t由正常的AE功能确定。然后，如果完全按下快门释放按钮，则以曝光时间t拍摄图像，并且将拍摄的图像存储在帧存储器中。同时，颜色编码电路根据亮度阈值对拍摄图像进行彩色编码，并且将彩色图像显示在LCD上。如果用户参照颜色编码图像选择与主要对象相当的区域的颜色，则确定图像的动态范围，伽马特征等，使得所选择的颜色中的区域可以具有正确的亮度。相应地校正图像，并且通过校正获取的图像数据被存储在记录部分中。

摘要： A camera section photographs a camera test chart. A calibration controller of the camera section reads out image data of the camera test chart, and executes calibration of the camera section by use of characteristic values of obtained image data and standard data, which is stored in an internal memory. Next, a printer test chart, printed by a printer section, is photographed by the calibrated camera section. Image data of the printer test chart is sent to the printer section from the camera section. A calibration controller of the printer section performs calibration of the printer section by use of characteristic values of obtained image data and standard data, which is stored in an internal memory.

摘要： An image capturing apparatus determines whether, if images are sequentially captured at a predetermined time interval, a main subject will hardly move in the images. The determination is made based on the detection by a tripod detection switch, which detects whether the image capturing apparatus is mounted on a tripod or not, etc. Only when it is determined that the main subject will be at the same position in the images, an imaging device including a solid state image sensor captures images multiple times at the predetermined time interval while an exposure control part changes exposures for the plurality of images, respectively. Then, the plurality of images with different exposures are combined into one image. Consequently, it is possible to combine the captured images, in which the main subject is at the same position, to obtain a desirable image with a broad dynamic range.

摘要： To provide an image playback apparatus that enables an image picked up and recorded with a wide dynamic range to be changed to the exposure desired by a viewer. An apparatus that performs image playback by outputting, to a monitor or printer, image data stored in an image storage unit such as built-in memory or a memory card, is equipped with a line-of-sight detection apparatus that detects the line-of-sight direction of the person viewing the image, or a touch panel, and is configured so that the area looked at by the viewer is automatically detected, or an arbitrary part of the screen can be specified by the viewer himself or herself from the touch panel. At first, conventional dynamic range playback is performed, then the dynamic range is changed, by changing the tone conversion curve, etc., for the part where the line-of-sight was detected within the screen, or the part specified by means of the touch panel, and a white-skip part or blackening part is reproduced appropriately.
