The present invention relates to an image processing apparatus which suppresses appearance of a color moire of a color image signal of a wide dynamic range which is produced using an image signal acquired using, for example, a CCD image sensor of the single plate type or the like. A gradation conversion section 71 performs a gradation conversion process for a color mosaic image M to produce a modulated color mosaic image Mg. Color difference image production sections 72 and 3 use the modulated c...

An image processing apparatus of the present invention can perform appropriate edge enhancement processing on any image while preventing increases in noise and chromatic aberration in the process of image processing. The image processing apparatus obtains photographic information present at generation of the image, determines, based on the photographic information, an edge enhancement coefficient to be used in performing edge enhancement processing, and performs edge enhancement processing to th...

In a color-image pickup device, light is decomposed by R filters, G filters, B filters, and an infrared blocking film into R, G, and B components, and photoelectric conversion elements arranged in a light-reception area receive the R, G, and B components, and output R, G, and B picture signals. The relative reduction in the intensity of the R picture signal, which increases with the incident angle of the R component, is compensated for by relatively increasing the transmittance of the R componen...

An edge emphasizing circuit includes a first high-frequency detection circuit and a second high-frequency detection circuit. A spatial frequency of a raw image signal corresponding to a photographed object is detected by the first high-frequency detection circuit or the second high-frequency detection circuit, and a gain corresponding to a detection result is made effective. The gain to be made effective is decreased as the spatial frequency of the raw image signal is low. The gain is applied to...

An electronic camera is adapted for processing images of different resolution to provide a user selectable image record size. A buffer memory is provided for storing color image pixels from a sensor corresponding to at least one image. Processing responsive to a resolution mode switch controls the order in which color image pixels are selected for output storage in both vertical and horizontal directions. The order selected by the resolution switch includes a full resolution mode, and at least o...

According to the image taking apparatus and the method of controlling an edge enhancing level of an original image signal, as the electronic zooming rate for the original image signal increases, an amplitude level of the edge signal decreases in a direction contrary to the increase of the electronic zooming rate, and thereby, an edge enhancing level of the edge-enhanced image signal is automatically suppressed. Accordingly, even though zooming processing is applied to the edge-enhanced image sig...
