Image processing apparatus with automatic image pickup feature
First Claim
1. An image processing apparatus, comprising:
- a change detecting portion for detecting a change between picture planes of input motion picture data and outputting a first control signal indicating a transition from a small change state to a large change state and a second control signal indicating a transition from a large change state to a small change state; and
an operation control portion for controlling starting and stopping of recording or transmission of input motion picture data according to said first control signal and said second control signal, wherein during recording or transmission, said operation control portion controls to stop recording or transmission of said input motion picture data if no outputting of said first control signal occurs until after a prescribed time T1 elapses after said second control signal is output.

Abstract
The image processing apparatus includes a change detecting portion for outputting a first control signal indicating transition from a small change state to a large change state and a second control signal indicating transition from a large change state to a small change state between picture planes of input motion picture data, and an operation control portion for controlling starting and stopping of recording or transmission of input motion picture data according to the first control signal and the second control signal. During recording or transmission, the operation control portion controls to stop recording or transmission if the first control signal is not output until after a predetermined arbitrary time T1 elapses after the second control signal is output.

9. An image processing apparatus, comprising:
-
a change detecting portion for detecting a change between picture planes of input motion picture data and outputting a first control signal indicating a transition from a small change state to a large change state and a second control signal indicating a transition from a large change state to a small change state; and
an operation control portion for controlling starting and stopping of recording or transmission of input motion picture data according to said first control signal and said second control signal, wherein said operation control portion controls to start recording or transmission of input motion picture data as soon as an operation is activated for controlling starting and stopping of recording or transmission by said operation control portion, and thereafter controls to stop recording or transmission of said input motion picture data when a prescribed time period T2 has elapsed without said first control signal being output. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. An image processing apparatus, comprising:
-
a motion compensation prediction portion for dividing a picture plane of input motion picture data into prescribed regions, performing for each region a motion compensation prediction with a reference picture plane stored in a frame memory, and outputting a prediction error, a motion vector of said each region, and a sum of squared difference of luminance values of pixels within said region between picture planes;
a prediction error coding portion for coding said prediction error and outputting coded motion picture data;
a change detecting portion for detecting a change between picture planes from said motion vector and said sum of squared difference and outputting a first control signal indicating a transition from a small change state to a large change state and a second control signal indicating a transition from a large change state to a small change state; and
an operation control portion for controlling starting and stopping of recording or transmission of input motion picture data according to said first control signal and said second control signal. - View Dependent Claims (20)
