摘要： The present invention relates to a method of converting 2D images into 3D images by producing from a 2D image signal a main image signal and a sub-image signal delayed from the main image signal. In the present invention, a temporary field delay from the main image signal to the sub-image signal is found on the basis of data related to the movement in the current field of the main image signal (a first step). A target field delay is then found on the basis of the temporary field delay found in the first step (a second step). A true field delay used in the succeeding field is found on the basis of the target field delay found in the second step and the true field delay used in the current field (a third step).

摘要： Auto focus control and/or auto exposure control is carried out by using a luminance signal before gamma correction, before addition of aperture signal but after hand shake correction. Auto white balance control is carried out by using a color signal after hand shake correction. Consequently, precise auto focus control, auto exposure control and/or auto white balance control can be done.

摘要： A method of converting two-dimensional images into three-dimensional images. When the movement of a main image is fast, a main image signal is written into field memories for each field. When the movement of the main image is slow, the main image signal is written into the field memories at intervals of a predetermined number of fields. An image to be read out as a sub-image from the field memories is determined on the basis of the speed of the movement of the main image.

摘要： In the present invention, two-dimensional images are converted into three-dimensional images by producing from a two-dimensional image signal a main image signal and a sub-image signal delayed from the main image signal. A field delay indicating how many fields are there from a field corresponding to the main image signal to a field corresponding to the sub-image signal is changed depending on the speed of the horizontal movement of the main image signal. The upper limit of the field delay is determined on the basis of vertical components of motion vectors detected from the main image signal. The field delay is so determined that it is not more than the determined upper limit.

摘要： A video signal processing circuit is incorporated in an IC for camcorder in which a camera signal outputted from a CCD image sensor is processed in a digital manner such that luminance and color signals can be outputted. In the IC, a vertical interpolation circuit produces two kinds of vertically interpolated data on the basis of a digital camera signal of one channel within an image area being set by an electronic zoom function. A YC separation circuit receives the two kinds of vertically interpolated data, and an output of the YC separation circuit is applied a horizontal interpolation circuit or an RGB composition circuit. If the YC separation output is applied to the horizontal interpolation circuit, the same outputs two kinds of horizontally interpolated data upon which three primary color signals are composed by the RGB composition circuit. If the YC separation output is applied to the RGB composition circuit, the horizontal interpolation circuit produces two kinds of horizontally interpolated data on the basis of three primary color data outputted by the RGB composition circuit.
