摘要： An electronic camera is provided with a touchscreen. When a cameraman touches the touchscreen on a principal subject in a captured image shown on the touchscreen, the touched portion is determined and the focus and exposure are adjusted in conformity with the principal subject. When the image is designated to be stored, positional information on the principal subject as well as image information is stored into a built-in memory or a detachable external memory. For this reason, wherever the principal subject is located on the image, the image-capturing is performed with favorable results. The positional information on the principal subject is utilized for printing or reproducing the image so as to perform image tone corrections such as correction of brightness and skin pigmentation in an area including the principal subject, so that a high-quality image can be printed or reproduced.

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. By calibrating both the camera and the printer sections, it is possible to execute effective calibration of the apparatus.

摘要： The present invention aims to provide satisfactory color reproduction without causing color mixing when a color image is formed on a direct heat-sensitive color recording medium. To input values of R, G and B, matrix calculation is performed to intensify chroma. To the output at a matrix calculation unit 10, contrast is decreased with respect to a predetermined color component of a predetermined color, and selective color correction processing is performed to exclude color mixing. Then, colors are converted to Y, M and C respectively. As a result, when an image of M color is formed or when an image of M component is formed during the formation of an image in red color, higher contrast is obtained compared with the case where an image in gray color is formed until the value of M reaches a certain value, and density of said color is made lower than the density during the formation of the image in gray color when the signal value exceeds said value, and color mixing does not occur. The same applies to the case where an image in Y component only is formed and when an image in Y component is formed during the formation of an image in green color.

摘要翻译： 本发明的目的是提供令人满意的彩色再现，而不会在直接热敏彩色记录介质上形成彩色图像时引起混色。 为了输入R，G和B的值，执行矩阵计算以加强色度。 对于矩阵计算单元10的输出，相对于预定颜色的预定颜色分量减小对比度，并且执行选择性颜色校正处理以排除混色。 然后，颜色分别转换为Y，M和C. 结果，当形成M色的图像时，或者在形成红色图像时形成M分量的图像时，与形成灰色的图像直到形成值为止的情况相比，获得了更高的对比度 的M值达到一定值，并且当信号值超过所述值时，使所述颜色的浓度低于形成灰色图像时的浓度，并且不发生混色。 这同样适用于仅形成Y分量中的图像，并且在形成绿色图像期间形成Y分量中的图像的情况。

摘要： A suitable image signal is obtained even with regard to a subject exhibiting a very large difference in luminance between bright and dark areas. A video signal obtained from a CCD by imaging the subject is amplified by a first amplifier, converted into digital image data A by a first A/D converter and then stored in a first memory. The video signal from the CCD is also amplified by first and second amplifiers, converted into image data B by a second A/D converter and then stored in a second memory. The amplification factor of the first second amplifier is set such that a comparatively dark area of the image of the subject will assume a level having an appropriate brightness. A multiplexer selects data representing a comparatively bright area of the image of the subject from image data read out of the first memory as well as data representing a comparatively dark area of the image of the subject from image data read out of the second memory. The selected items of data are combined (by inlay synthesis) to obtain image data representing an image exhibiting overall brightness.
