An object of the present invention is to generate an image which is prevented from being influenced by a movement while suppressing increase in noise components. When a movement is detected during exposure of an image capturing device to light, an image capturing apparatus stops the exposure of the image capturing device and amplifies an image signal obtained with the exposure, thereby compensating exposure shortage. Luminance information is extracted from a captured image, and color information is extracted from a live view image obtained at a timing different from a timing at which the captured image is obtained. By synthesizing the luminance information of the captured image and the color information of the live view image, noise components included in color information are reduced.

Image processing apparatus and method

A camera system includes a camera for photographing an object and acquiring image data of the object, and a computer connectable to the camera. The camera is provided with a manipulation member and a camera controller for detecting an operation of the manipulation member and transmitting a signal based on the detected results to the computer. The computer is provided with a controller for controlling a screen of a display functioning together with the computer based on the signal received from the camera.

An image processing device gives an alarm if deletion of image is directed in a state that the image has not yet been transferred from an image recording medium into a storage medium having a larger capacity. Also, when a deletion operation is performed for image, the image processing device compresses and stores the corresponding image file in accordance with an evaluation rank based on history data for the image. Therefore, the image processing device allows effective use of the storage medium having a limited capacity by contriving compression processing of the image file.

Image processing device for processing images which are recorded in a recording medium and a method thereof

An image captured with a CCD is divided into blocks. Light amount correction data each set for each one of the blocks are read out from a correction value table, a correction value generatorweights the light amount correction data in accordance with the positions of target pixels to thereby generate correction values for the respective target pixels, and image field edge brightness reduction correction is performed on the respective pixels based on the correction values. Since one piece of the data is set for each block, the volume of the data is small. This also prevents boundaries between the blocks from becoming noticeable.

Digital camera, image signal processing method and recording medium for the same

Digital camera techniques improve the convenience of a live view display and the like. Image processing in a digital camera includes image processing (i.e., live view processing) for real-time display of a subject on a liquid crystal monitor and image processing performed on image signals followed by image capture for recording. Both the image processing is performed by a single common image processor. In image capture for recording, high-priority live view processing (Pc) is performed between writing (Pa) of image signals outputted from a CCD into memory and captured image processing (Pb). This shortens the time of not displaying a live view image, thereby preventing a shutter release opportunity from being missed and improving the convenience of a live view display.

Method for live view display and digital camera using same

An image retrieval system for retrieving a plurality of images recorded in a recording medium, records data concerning operations and processing for image files as history data. A desired image is found based on the history data. Further, an image is found based on a combination of photographing condition in a photographing operation, and the history data of the operations executed for the image file. Therefore, the image retrieval system allows the image to be efficiently, exactly, and conveniently found without a trouble of assigning key information to the image file.

Image retrieval system for retrieving a plurality of images which are recorded in a recording medium, and a method thereof

An image display apparatus has a display for displaying image data and a controller having a display mode in which, from an image recording medium on which a plurality of image files each containing low-resolution image data and high-resolution image data are recorded, the low-resolution image data of each of the image files is displayed successively on said display. Thus, particular images can be extracted quickly and reliably from a number of image files.

Image display apparatus

An photographing apparatus comprises a photographing lens, a first area sensor, a second area sensor, a display, a manipulation unit, and a processor. The first area sensor has a plurality of pixels, and photoelectrically converts an optical image of an object into first pixel data. The second area sensor has a plurality of pixels, the number of pixels of the second area sensor being greater than the number of pixels of the first area sensor, and photoelectrically converts an optical image of an object into second pixel data. The display displays the first pixel data supplied from the first area sensor as a preview image before image recording. The manipulation unit allows a user to start image recording. The processor combines the first pixel data and the second pixel data supplied form the first and second area sensors to produce a composite image when the manipulation unit is operated.

A camera is disclosed which has means for receiving an electric wave which is transmitted from an external device in a wireless manner (e.g., equipment for radio navigation systems, satellites and radio stations). When an image of an object is recorded at every shot on a recording medium loaded in said camera, a data corresponding to every shot is recorded in accordance with the electric wave received by said receiving means. Preferably said camera further has means for detecting a place where the photo-taking operation is carried out and in accordance with the detection of said detecting means, the data corresponding to every shot is recorded.
