Image processing device, data recording device, and method of controlling image processing device

An image processing device having an interlace/progressive conversion section that receives interlaced image data and converts the interlaced image data into progressive image data, the image processing device comprising:

• a conversion mode setting register in which mode information relating to a conversion format is set,
• the interlace/progressive conversion section including a normal mode conversion section and an interpolation mode conversion section;
• when a value indicating a first mode is stored in the conversion mode setting register, the normal mode conversion section storing interlaced image data corresponding to odd-numbered lines and interlaced image data corresponding to even-numbered lines received before or after the interlaced image data corresponding to the odd-numbered lines in an image data buffer, and generating a progressive image by using the image data corresponding to the odd-numbered lines or the image data corresponding to the even-numbered lines that is stored in the image data buffer and corresponds to a line number of an image to be output;
• when a value indicating a second mode is stored in the conversion mode setting register, the interpolation mode conversion section sequentially receiving image data corresponding to odd-numbered lines or sequentially receiving image data corresponding to even-numbered lines,
• the interpolation mode conversion section performing an even-numbered-line interpolation process that uses sequentially-received image data corresponding to first and second odd-numbered lines and generates image data corresponding to an even-numbered line between the first and second odd-numbered lines, or an odd-numbered-line interpolation process that uses sequentially-received image data corresponding to first and second even-numbered lines and generates image data corresponding to an odd-numbered line between the first and second even-numbered lines;
• after the even-numbered-line interpolation process, the interlace/progressive conversion section generating a progressive image by using image data corresponding to the odd-numbered lines and image data corresponding to the even-numbered lines generated by the even-numbered-line interpolation process;
• and
• after the odd-numbered-line interpolation process, the interlace/progressive conversion section generating a progressive image by using image data corresponding to the even-numbered lines and image data corresponding to the odd-numbered lines generated by the odd-numbered-line interpolation process.
