Image processing apparatus that can provide image data of high quality without deterioration in picture quality
First Claim
1. An image processing apparatus comprising:
- image signal output means for converting sensed light incident from an object into a digital video signal,signal processing means for applying a signal process on said digital video signal to output a digital video signal,first conversion means for converting said digital video signal into image data having a first image format,second conversion means for converting said image data of the first format into image data of a second format, the second format being a modified version of the first format,conversion control means, responsive to a format specification signal that specifies a format conversion, for selecting and controlling the operation of only said first conversion means to convert the image data into the first format and for selecting and controlling the operation of both the first and second conversion means to convert the image data into the second format, andoutput means, connected to each of the first and second conversion means, for outputting the converted image data in one of the first and second formats.

Abstract
Digital image data obtained by A/D converting an output signal from an image sensing device by an A/D conversion circuit is converted into image data corresponding to a predetermined image format by a digital process of an image conversion circuit. Therefore, an image of higher quality without deterioration in the picture can be provided in comparison with the case where digital image data obtained by A/D converting an output signal from an image sensing device is first converted into analog video data and then into A/D data. Further format conversion can be performed using a series of controllable image converters. The image converters and a signal processing unit can be selectively programmed to perform a variety of format conversions and image-type specific signal processing, respectively. Programming can be performed manually or automatically according to the type of input device or the type of information in the image.
