Abstract

The present invention is constructed with a TV processing stage (1), a camera-image processing stage (2), a micom-video processing stage (3), an image-processing stage (4) and a switching state (5) on the cooking apparatus. Therefore the user can watch TV programs and can observe selected area through video cameras without leaving the cooking area. The user can also identify the automatic cooking information on TV screen. The micom-video processing state (3) performs a converting function that converts the stored cooking information data into a video signal.

Claims

1. A cooking apparatus with a video display, comprising

(a) a television processing means for processing a first video signal,

(b) a camera-image processing means for processing a second video signal from a video camera,

(c) a heat-controlling means which performs general functions of a cooking apparatus characterized in that a micro-video processing means for converting automatic cooking information into a third video signal is connected to said heat-controlling means and is adapted to monitor said cooking apparatus during a cooking cycle, and

(d) an image-processing means for displaying said video signals, and

(e) a switching means connected to said television processing means, said camera-image processing means and said micom-video processing means to permit switching of each means for displaying said video signal according to the user'"'"'s selection.

2. The apparatus of claim 1 wherein said micom-video processing means comprises:

(g) a microcomputer adapted to input an automatic cooking-selector signal from said heat-controlling means, and to output said automatic cooking information in the form of said third video signal,

(h) at least one ROM adapted to store said automatic cooking information permanently,

(i) at least one RAM adapted to store said automatic cooking information temporarily,

(j) a decoder between said microcomputer and at least one of said ROM and said RAM,

(k) buffers separating the output of said microcomputer and the input of a video display generator(VDG) on tri-state,

(l) the VDG generating an inverted video signal by combining the automatic cooking information and sync. signals which are generated from an external clock pulse, and

(m) a phase-inverting circuit for inverting said inverted video signal from said VDG.

3. The apparatus of claim 2 wherein

said microcomputer controls at least one repeating function of said micom-video processing means, comprising bringing out the automatic cooking information from said ROM, storing said information in said RAM temporarily, outputting said information to the video display generator, and recognizing said automatic cooking-selector signal from said heat-controlling means.
