Audio regeneration data indicating where sound during audio regeneration is stored is recorded in a recording medium together with captured image data when image-capturing. The image data recorded in the recording medium and the audio regeneration data is read during image regeneration process. The image is displayed in accordance with the image data while the sound during the image-capturing is regenerated in accordance with the audio regeneration data. Therefore, the image and the sound can be easily appreciated simultaneously and the image regeneration can be effectively enjoyed.

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.

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.

Image forming apparatus and method for calibrating the same

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,, 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.

Method and apparatus for color correction

A suitable image is obtained of a subject in which the difference in luminance between a bright area and a dark area is very large. The dark area is properly exposed and first image data is obtained. The bright area is properly exposed, and second image data is obtained. The first image data pertaining to the bright area is replaced with the second image data, thereby obtaining composite image data. This is accomplished using an array of photodiodes comprising two sets of photodiodes, one set of the photodiodes comprising filters, and the respective sets of photodiodes output signals to respectively different transfer paths for signal processing.

Video camera, imaging method using video camera, method of operating

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.

A movie camera and a method of photographing a still with the movie camera is provided wherein the movie camera is of a type wherein a motionless picture or still can be photographed during a movie photography operation and when the illumination falling on an object is a predetermined value or less at the start in the photography of the still during the movie photography operation, stroboscopic flashes of light are produced from a strobe device to enable still photography. The movie camera basically includes a CCD for converting image information corresponding to light incident on a lens into an electric signal, a movie-photography triggering signal generating device for starting a movie photography operation, a still-photography triggering signal generating device for starting a still photography operation, and an electronic shutter speed switching device for changing over the shutter speed to a desired shutter speed faster than that at the time of the movie photography when the still-photography triggering signal generating device is activated to start the still photography operation during the movie photography operation. According to the above construction, the strobe device automatically produces flashing light in synchronism with the shutter timing of a high-speed operated shutter for thereby enabling instant photography of a desired motionless picture.
