摘要:
A first intermediate image generating means (1) generates an intermediate image (D1) by extracting a component of an input image DIN in a particular frequency band; a second intermediate image generating means (2) generates an intermediate image D2 having a frequency component higher than the intermediate image (D1); a first intermediate image processing means (3M) generates an intermediate image (D3M) by amplifying the pixel values in the intermediate image (D1); a second intermediate image processing means (3H) generates an intermediate image (D3H) by amplifying the pixel values in the intermediate image (D2); and an adding means (4) adds the input image (DIN) and the intermediate image (D3M) and the intermediate image (D3H) together to obtain an output image (DOUT). A first amplification factor (D3MA) and a second amplification factor (D3HA) are determined according to pixel values in the input image (DIN). Even if the input image includes a fold-over component on the high-frequency side or does not include an adequate high-frequency component, an enhanced image can be provided without causing overshoot.

An image reading apparatus configured to read a document at a second resolution based on a result of reading the document at a first resolution generates image data with low data amount having small data amount from image data-for-save that has been read at the second resolution and transfers the image data with low data amount taking priority over the image data-for-save to an image processing apparatus. The image processing apparatus is configured to notify a user that next reading processing is acceptable when receiving of the image data with low data amount is completed. The image processing apparatus is configured to receive and store the image data-for-save according to the next reading processing instructed by the user.

Systems for determining a movement amount detect a steering angle of a moving body on which a camera is mounted and extract matching inspection areas of a prescribed shape and size from frames captured by a camera. The systems rotate the inspection area of a second frame relative to the inspection area of a first frame, the rotation based on the detected steering angle. The systems execute pattern matching between the inspection areas and calculate positions of subject points that correspond to identical characteristic points in each frame. The systems, methods, and programs determine the movement amount based on a displacement amount between the calculated subject point positions.

A pixel signal having a k-th spectral characteristic at a pixel interpolation position occupied by a pixel signal having an h-th spectral characteristic is generated from a set of pixel signals arrayed in a two-dimensional plane, each having one of a plurality of spectral characteristics, by calculating a difference between low-frequency components, corresponding to a degree of correlation between pixel signals having the k-th and h-th spectral characteristics in a neighborhood of the pixel interpolation position (8r, 8g, 8b, 24k, 24h, 26), calculating a non-correlation value corresponding to a degree of non-correlation between the pixel signals having the k-th and h-th spectral characteristics in the neighborhood of the pixel interpolation position (7r, 7g, 7b, 23k, 23h, 25), and obtaining the pixel signal having the k-th spectral characteristic at the pixel interpolation position by using the calculated difference and the non-correlation value (27, 28, 29). Accurate interpolation can be performed despite various different correlation relationships between color component values.

An image capture apparatus which is compact and structurally simple and allows for prevention of a flicker noise, a method of capturing an image which allows for prevention of a flicker noise, and a mobile terminal using the apparatus and the method, are provided. In the image capture apparatus, a vertical cycle is adjusted so as to maintain 20 fps or 20/2m (m is an integer) fps, thereby to prevent a flicker noise in an image as obtained. To this end, in the image capture apparatus, a frequency of a horizontal transfer clock, a horizontal count level and a vertical line count level may be adjusted. Further, a fraction count is provided to adjust the length of one vertical cycle. Moreover, the image capture apparatus may be incorporated in a mobile terminal.

An imaging apparatus including at least an imaging device having a plurality of photoelectric transfer devices arranged in matrix-shape to detect a light irradiated to each photoelectric transfer device and transfer to electric signal, and imaging means for imaging an image of a photogenic object on a surface of the imaging devices. The imaging means images at least two similar images of the photogenic subject on different area of the surface of the imaging device, and the imaging apparatus further includes electric signal processing means to form one image of photogenic subject from at least two images of photogenic subject. Since a plurality of images of photogenic subject can be formed on the imaging device by a plurality of image formation lenses, a thinner imaging apparatus can be realized.

An image pickup apparatus captures an image from a subject without a focus-adjusting mechanism. An image pickup element has opposed first and second surfaces and an image region formed in the first surface. An optical system causes the image light from the subject to form an image on the image region. A supporting member has a first abutment portion that engages the optical system with nothing sandwiched therebetween, and a second abutment portion that engages the image pickup element with nothing sandwiched therebetween, thereby accurately positioning the optical system relative to the image pickup element. The second abutment portion abuts an area on the first surface except for the image region. A circuit board is fixed to the supporting member and electrically connected to the image pickup element. The circuit board has an opening formed therein such that the image region is exposed through the opening.
