Problems solved by technology

For example, the detection of image correlation cannot represent the difference between a shot focused on a scene involving considerable motion and a shot of an unintentionally zoomed scene, such as a pan pan, which is the same as that of a scene involving considerable motion. Shoot complex parts with approximations

Embodiment Construction

[0017] Best Mode for Carrying Out the Invention

[0018] Embodiments according to the present invention will now be described with reference to the accompanying drawings.

[0019] figure 1 is a block diagram showing a control model of a video recording / reproducing apparatus including various control microcomputers or the like in combination with a compression and encoding apparatus, and a video camera.

[0020] The lens system 1 is composed of a zoom lens 1z and a focus lens 1f. The light from the target is input to the photographing device 2 through the intermediate body of the lens system 1 . In the imaging device 2, an image of a target is acquired from three image signals corresponding to three colors, ie, RGB (red, green, and blue). At this time, the position of the lens system 1 is controlled such that it always remains focused on the target. The image signal from the photographing device 2 is sent to the A / D converter 3 as moving image data, and the A / D converter 3 ...

Abstract

A video recording / reproducing apparatus combined with a camera adapted to control a target information amount according to the nature and properties of an animated image to be photographed, and a recording control method for the same are provided. A target information amount control microcomputer ( 7 ) controls an encoding and compressing apparatus ( 10 ) by a target bit rate to carry out predetermined compressive encoding on the animated image data from a filter computing unit ( 4 ) so as to create an encoded bit stream. The filter computing unit ( 4 ) is given a filter coefficient to convert the animated image data into data of a resolution that is suited for encoding.

Description

Field of Invention [0001] The present invention relates to a video recording / reproducing apparatus combined with a video camera (camara) for signal encoding a photographic image and then recording the image on a predetermined recording medium. More particularly, the present invention relates to a recording control method of a video recording / reproducing apparatus combined with a video camera for performing proper quality image processing of image data of an imaged object based on imaging control data for setting imaging conditions in an imaging unit. Compression coding for optimal image control processing. Background technique [0002] MPEG2 (Moving Picture Experts Group Phase 2) is an encoding system for broadcasting and AV equipment, and is widely used as a technology for compressing information such as images, audio, voice, and data. [0003] MPEG2's standard type of compression and encoding device enables improved image quality after decompression, by encoding the input...
