Abstract:
An image pickup apparatus for receiving an input image and producing an output image, the image pickup apparatus comprising:an image pickup element having more pixels than those in the output image, said image pickup element configured to receive the input image and produce an intermediate image having a first number of pixels; and a pixel number conversion means configured to receive the intermediate image, said pixel number conversion means operating to reduce the first number of pixels in the intermediate image to produce the output image, said pixel number conversion means including: a horizontal pixel interpolating filter configured to interpolate signals between horizontal pixels, a plurality of line delay devices configured to store interpolated signals from said horizontal pixel interpolating filter, a vertical pixel interpolating filter, and a memory controller configured to selectively transmit stored interpolated signals from said plurality of line delay devices to said vertical pixel interpolating filter to interpolate signals between vertical pixels.
