An image pickup apparatus comprises an image pickup element that includes a plurality of photoelectric conversion elements, and is operable in a first drive mode for reading a low resolution image based on an output of the photoelectric conversion elements or a second drive mode for reading a higher resolution image than the low resolution image, a drive unit that drives the image pickup element, a frame memory that stores image data read by the image pickup element in the first drive mode, an image enlarging portion that enlarges an image size of the image data stored in the frame memory, and a noise reduction unit that performs noise reduction on image data read by the image pickup element in the second drive mode, based on the image data enlarged by the image enlarging portion. This configuration enables high frame rate moving images to be obtained. Further, degradation of image resolution can be prevented, and random noise contained in images can be suppressed.

A solid state imaging apparatus includes two-dimensional frequency process which is applied to an output signal from each pixel of a progressive scan-type CCD. The CCD has an an arrangement of color separation filters without making carriers in the horizontal and vertical directions of the two-dimensional frequency to obtain chrominance signals with less moire in the horizontal and vertical directions of the two-dimensional frequency. A luminance signal with less moire in the horizontal and vertical directions of the two-dimensional frequency can be obtained by interpolating with the ratio of a chrominance signal with less moire.

A visual processing section 120 is provided which performs visual processing on a pixel-by-pixel basis according to a predetermined function defining a relation between a pixel value of a target pixel which is a pixel under visual processing and a pixel value of the target pixel after subjected to the visual processing. An input signal processing section 150 is further provided which performs, on a pixel-by-pixel basis, at least one of signal processing to restore resolution of an image data input to the visual processing section 120 and signal processing to correct signal deterioration due to the visual processing. In the input signal processing section 150, the at least one signal processing is performed according to a gain determined by using the function.

An imaging apparatus is provided for reducing noise which is derived from random noise contained in a correction signal used for correcting an image data and is newly generated on correction of the image data. The imaging apparatus drives vertical transfer registers (302) with no signal charge from photoelectric transducers (301) read out to the vertical transfer registers (302) to obtain and store a correction signal into a field memory (7). The apparatus subtracts the correction signal from the image data by a subtractor (8).
摘要:
A solid-state imaging apparatus having color separation filters is provided which produces a signal with reduced chrominance and luminance moire and thereby improves resolution, and the spectral characteristics of the color filters for the solid-state imaging apparatus are so set that when the spectral characteristic of each color filter is multiplied by a prescribed coefficient, the sum of four or two horizontally adjacent pixels becomes approximately equal between two vertically adjacent lines. A coefficient multiplying circuit multiplies an output signal from each color filter by the prescribed coefficient, and signal processing is performed.
