摘要： Image enhancement processing can be carried out efficiently on image data obtained by a digital camera while a difference between models of digital cameras can be suppressed. Digital cameras are classified into groups of predetermined level ranges regarding characteristics of color, tone, sharpness and noise. Image processing conditions are also set for the respective groups in accordance with the level ranges thereof. When image enhancement processing is carried out on image data obtained by a the digital camera, the groups the digital camera belongs to are found for the respective types of characteristic, and the image processing conditions therefor are used for the enhancement processing.

摘要： A hand-held device comprising a housing (10) shaped and dimensioned to allow the device to be hand held, a display (12) secured to the housing for displaying moving pictures on a frame-by-frame basis, and a camera (16, 18) having an optical axis (O) extending generally away from the display to image a person who is viewing the display. The hand-held device further comprises a sensor (20) configured to determine a rotational angle between an alignment axis (V) of the hand-held device and a reference alignment axis in real space. Alternative embodiments use a reference alignment axis obtained on the basis of data content of the images, as determined by image processing techniques. In this way, subjective picture quality can be improved by compensating for vertical mis-alignment of the image content of the frames obtained by the camera.

摘要： An object of this invention is to correct the nonuniformity between a plurality of image sensing regions in real time and cope with even dynamic variations such as temperature variations or variations over time. To achieve this object, a correction apparatus includes a plurality of level adjustment devices which independently adjust the levels of a plurality of image sensing signals output from a plurality of output terminals, an output level detection device which detects the output levels of the plurality of level adjustment devices, and a correction coefficient determination device which determines a correction coefficient for reducing the level difference between the image sensing signals on the basis of the detection result of the output level detection device. The correction coefficient determination device determines the correction coefficient by excluding an object-dependent level difference component in which the level difference between the plurality of image sensing signals exceeds a predetermined level difference. The correction coefficient determination device supplies the determined correction coefficient to the level adjustment devices to perform adjustment so as to reduce the level difference between the image sensing signals.

摘要： A camera creates successive digital images of a scene, and computes a stability measure estimate blur in a final photograph of the scene. The camera combines information such as lens focal length, focus distance, scene brightness value, and shutter speed to determine alternate camera settings that may reduce the blur. The camera communicates to the photographer suggested camera setting changes that may reduce the blur. The communication may optionally happen before the final photograph is taken or after, and may take one of several forms. The camera may optionally be a digital camera. The setting change suggestions may optionally be stored in an image file with a final digital photograph.

摘要： An image-capturing apparatus, in which solid-state image-capturing elements having a large number of pixels are used, capable of suitably performing image-quality correction on a captured image. In a monitor reading mode, a camera system LSI (6) detects the read image signal which is read by thinning out pixels by an image-capturing device (3). Based on the detected data, control values for image-quality correction are computed in a microcomputer (9), and the camera system LSI (6) performs an image-quality correction process on the image signal based on these control values. When the image-capturing device shifts to a capture reading mode, the camera system LSI (6) temporarily stores the image signal, in which all the pixels are read, in the image memory (7), thereafter reads the image signal and detects it. The microcomputer (9) computes a control value on the basis of this detected data and the detected data in the previously used monitor reading mode. Thereafter, the camera system LSI (6) reads the image signal again, and performs an image-quality correction process on the basis of the control values by the microcomputer (9).

摘要： Image quality degrading components can be eliminated from a contour correction signal of high frequency region that is used for contour correction. A filtering section extracts a high frequency region signal from a signal inputted from a VLPF. A mask generating section generates a mask by masking image quality degrading components (e.g., ringing components) contained in the extracted signal. A gain factor generating section generates a gain factor that eliminates image quality degrading components on the basis of the mask. A multiplier multiplies the extracted signal by the gain factor, and outputs an adder a resultant signal (horizontal contour correction signal free from the image quality degrading components). Since the horizontal contour correction signal is generated by eliminating the image quality degrading components from the high frequency region signal, the occurrence of ringing and the like can be suppressed to ensure excellent image quality.

摘要： The present invention provides a camera shake correction device enabled to quickly correct a camera shake. This device has a sensor for detecting movement of a camera, a high-pass filter, an amplifier, an A/D converter, a camera-shake/pan/tilt detection unit, and a switching unit. The filter includes a circuit having a capacitor and a resistor connected in series. A reference voltage is inputted to a common ground terminal of the circuit. An output signal of the sensor is amplified by the amplifier. The A/D converter converts the amplified signal into a digital value. The detection unit detects a camera shake or panning/tilting according to the digital value. When detected, the switching unit turns on a switch connected to the resistor so as to discharge the capacitor to the reference voltage.
