Abstract

Abstract An image processing apparatus which includes a light reception surface for generating a light reception signal from between a pair of electrodes when in a light receiving condition. Shutter means are provided which have numbers of shutter elements linearly or two-dimensionally arranged so as to correspond to the light reception element and so that an image is projected on front surfaces of the shutter elements. Scanning means are arranged to generate a scanning signal at a predetermined timing so as to successively cause the shutter elements to open in response to the scanning signal. Image encoding means process the light reception signal from the light reception element in the series in synchronism with the scanning signal to generate a coded signal which corresponds to the image projected on the shutter means.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 165 words
An image processing apparatus for processing an image comprising: a light reception element including a light reception surface for generating a light reception signal in response to light being incident thereon; shutter means having a plurality of shutter elements disposed between the image and said light reception element; scanning means arranged to generate a scanning signal at predetermined timing so as to successively cause said shutter elements to open in response to said scanning signal to enable light to pass therethrough; a luminance element for emitting light in synchronism with said light reception signal from said light reception element; an auxiliary shutter means constituted by a plurality of auxiliary shutter elements arranged correspondingly to said shutter elements of said shutter means; and an image reproducing means for causing said auxiliary shutter elements of said auxiliary shutter means to open to response to said scanning signal in synchronism with said shutter elements to selectively pass the light from said luminous element to thereby reproduce said image.
Claim 2
Dependent Claim 165 words
An image processing apparatus for processing an image comprising: a light reception element including a light reception surface for generating a light reception signal in response to light being incident thereon; shutter means having a plurality of shutter elements disposed between the image and said light reception element; scanning means arranged to generate a scanning signal at predetermined timing so as to successively cause said shutter elements to open in response to said scanning signal to enable light to pass therethrough; a luminance element for emitting light in synchronism with said light reception signal from said light reception element; an auxiliary shutter means constituted by a plurality of auxiliary shutter elements arranged correspondingly to said shutter elements of said shutter means; and an image reproducing means for causing said auxiliary shutter elements of said auxiliary shutter means to open to response to said scanning signal in synchronism with said shutter elements to selectively pass the light from said luminous element to thereby reproduce said image.
Claim 3
Dependent Claim 43 words
An image processing apparatus according to claim 1, in which said shutter elements comprise a first liquid crystal array of a plurality of liquid crystal picture elements, and said auxiliary shutter elements comprise a second liquid crystal array of liquid crystal picture elements.
Claim 4
Dependent Claim 20 words
An image processing apparatus according to claim 1 wherein said plurality of shutter elements is arranged in a linear array.
Claim 5
Dependent Claim 20 words
An image processing apparatus according to claim 1, wherin said plurality of shutter elements is arranged in a two-dimensional matrix.
Claim 6
Dependent Claim 48 words
An image processing apparatus according to claim 1 further including image encoding means for processing said light reception signal from said light reception element in time series and in synchronism with said scanning signal to generate a coded signal corresponding to said image projected on said shutter means.
Claim 7
Dependent Claim 25 words
An image processing apparatus according to claim 5 further including a comparator for producing a binary coded signal in response to said light reception signal.
