    摘要: In an image sensing apparatus, an array of two-dimensional matrix of photosensitive devices is used to detect an image. Each photosensitive device comprises a photosensor accumulating carriers when exposed to a light, control terminals, and an output terminal. A signal generator supplies a vector or a one-dimensional data to the control terminals in the array to output pixel data of the two-dimensional matrix, and the pixel signal is output through the output terminal. The control terminals of the photosensors arranged along each line are connected commonly, while the output terminals thereof arranged along each column are connected commonly. A controller supplies control signals to the control terminals. Then, pixel signal for columns designated by a control signal are output through an output circuit connected to the control terminals. Then, a partial region in the array including a region exposed by the light is determined according to the pixel signals, and data on the partial region is sent to the controller. Then, the controller supplies control signals in correspondence to the partial region. Then, correlation operation of the control signals with the amount of carriers in the photosensors are carried out while reading the pixel signals, and the pixel signals in the partial region is output.

    摘要: An imaging device reads an output level of a pixel circuit constituting a pixel array by supplying current to the pixel circuit. It reads a signal level and reset level from the pixel circuit by supplying it with the current from a current source circuit, and stores them into a line memory. A pixel level of the pixel circuit is obtained by a differential amplifier that outputs the difference between the signal level and reset level of the same pixel circuit. The gate potential of a current copier transistor that supplies the read current is set at a value that enables the read current to take a constant value from column to column of the pixel array. The image device can suppress variations in the current copier circuit provided for each array column of the pixel circuits, thereby reducing string-like noise in the image picked up.

    摘要: There is provided an image processor and a method thereof for high-speed compensation for taken-image blurs produced by camera shakes or the like. In the first instance, a motion-detecting area is selected for each of two images taken by an image sensor. When projective data is calculated by means of computing in a predetermined direction pixels of the motion-detecting areas, the motion vector between the two images can be acquired based on the projective data. The image correlativity between the two images is then calculated in the direction that the motion vector designates; and the amount of pixel displacement between the two images is calculated based on the correlativity values acquired by the calculation. Moreover, the area that has been produced by displacing an image output area in a camera-shake compensation area designated in the second frame, by the pixel-displacement amount calculated by a displacement calculator is cut away from the camera-shake compensation area, and is outputted as an image for the image output area of the second frame.
