摘要： A data processing apparatus includes a zoom circuit for displaying and a zoom circuit for recording. The zoom circuit for displaying performs a zoom process using a least square method or linear interpolation on image data from a YUV conversion circuit so as to create display image data. On an LCD monitor, an image based on the display image data thus created is displayed. Furthermore, the zoom circuit for recording performs a zoom process using spline interpolation or linear interpolation on image data from the YUV conversion circuit so as to create recording image data. The zoom process for recording is executed in parallel with the zoom process for displaying. The recording image data thus created is recorded in a recording medium.

摘要： A distortion correcting apparatus includes a buffer circuit which writes image data having horizontal pixels of a first number and a vertical-distortion different depending on a horizontal pixel position, into an SDRAM. The written image data is read-out for each units of horizontal pixels, which include a reference horizontal pixel and indicates a second number smaller than the first number, in a vertical pixel direction. A buffer control circuit in the vertical-distortion correcting circuit determines a second number in such a manner as to indicate a larger numerical value as a vertical-distortion corresponding to the reference horizontal pixel is smaller so as to start the buffer circuit. Also, the buffer control circuit changes a position of the reference horizontal pixel to a position corresponding to the second number at a timing based on a correction amount of the vertical-distortion correcting circuit so as to start the above-described determining process.
