    摘要： Provided is an image pickup device that enables distortion compensation with high precision. Exposure and reading are conducted on pixel rows that are discontinuous with respect to a vertical direction of an image pickup element, and multiple low resolution images are obtained. Each of these multiple low resolution images has a lower distortion than an ordinary image obtained by conducting an ordinary continuous exposure and reading. Therefore, output images with reduced distortion can be generated by using the low resolution images.

    摘要： A super-resolution processing portion has a high-resolution image generation portion that fuses a plurality of first input images together to generate a high-resolution image. The first input images are shot at a shutter speed equal to or faster than the super-resolution limit shutter speed, which is the lower-limit shutter speed that enables super-resolution processing to make the resolution of the output image equal to or higher than that of the input images. According to the amount of exposure, one of the following different methods for super-resolution processing is selected: a first method that yields as the output image the high-resolution image; a second method that yields as the output image a weighted added image resulting from weighted addition of the high-resolution image and an image based on an averaged image; and a third method that yields as the output image a weighted added image resulting from weighted addition of the high-resolution image and an image based on a second input image.

    摘要： An image processing apparatus includes a high resolution processing portion for generating a high-resolution image from a first low-resolution image to be a datum frame and M (M is an integer of one or larger) second low-resolution images, the high-resolution image having a higher resolution than the low-resolution images, and a region cutting out portion for setting a first target region in an image region of the first low-resolution image and for setting a second target region in an image region of the second low-resolution image. The high resolution processing portion calculates a pixel value of a region corresponding to the first target region in an image region of the high-resolution image based on pixel values of the first and the second target regions set by the region cutting out portion. The region cutting out portion scans the position of the first target region to be set in the first low-resolution image and sets the second target region at a position corresponding to the position of the first target region after the scan every time when the high resolution processing portion calculates the pixel value of the high-resolution image.

    摘要： In an image processing device, an edge detecting circuit 1 produces edge signals that represent edge components present in image signals, and an adder circuit 2 superimposes the edge signals on the image signals to produce edge-enhanced image signals. The image signals before edge enhancement are fed to a range setting circuit 3 so that, based on the image signals preceding and following a target image signal that is about to be processed by a clipper 4, a range in which the data value of the target image signal is allowed to vary is set. Based on the range of data values thus set by the range setting circuit 3, the clipper 4 clips the data values of the edge-enhanced image data.

    摘要： A left eye image signal and a right eye image signal which constitute a three-dimensional image are produced from a two-dimensional image signal. The horizontal phase of the produced left eye image signal is shifted, and the horizontal phase of the produced right eye image signal is shifted. Character signals are respectively mixed with the left eye image signal and the right eye image signal. A composite image comprising the three-dimensional image and the character signal is displayed on the basis of the left eye image signal with which the character signal is mixed and the right eye image signal with which the character signal is mixed.
