Abstract

Abstract An image processing apparatus divides an image signal corresponding to one frame into a plurality of blocks, and performs compression encoding for each block. The apparatus includes a display unit for displaying the image signal, a designation unit for designating a position desired by a user on the display unit, and a compression encoding unit for weighting the blocks and performing compression encoding therefor in accordance with the desired position designated by the designation unit. An image processing apparatus divides an image signal corresponding to one frame into a plurality of blocks, the image signal being output from a camera unit having focus adjustment unit for performing focus adjustment, and performs compression encoding for each block. The apparatus includes a display unit for displaying the image signal, a designation unit for designating a position desired by a user on the display unit, a compression encoding unit for weighting the blocks and performing compression encoding therefor in accordance with an output from the designation unit, and a control unit for controlling the focus adjustment unit in accordance with the desired position designated by the designation unit.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 74 words
An image processing apparatus for dividing an image signal corresponding to one frame into a plurality of blocks, and performing compression encoding for each block, comprising: a) display means for displaying the image signal; b) detection means for detecting a viewpoint position of an operator on said display means; and c) compression encoding means for weighting the blocks and performing compression encoding therefor in accordance with the viewpoint position detected by said detection means.
Claim 2
Dependent Claim 111 words
An image processing apparatus for dividing an image signal corresponding to one frame into a plurality of blocks, and performing compression encoding for each block, the image signal being output from a camera unit having focus adjustment means for performing focus adjustment, comprising: a) display means for displaying the image signal; b) detection means for detecting a viewpoint position of an operator on said display means; c) compression encoding means for weighting the blocks and performing compression encoding therefor in accordance with the viewpoint position detected by said detection means; and d) control means for controlling said focus adjustment means in accordance with the viewpoint position detected by said detection means.
Claim 3
Dependent Claim 72 words
An image processing apparatus for dividing an image signal corresponding to one frame into a plurality of blocks, and performing compression encoding for each block, comprising: a) display means for displaying the image signal; b) designation means for designating a position desired by a user on said display means; and c) compression encoding means for weighting the blocks and performing compression encoding therefor in accordance with an output from said designation means.
Claim 4
Dependent Claim 109 words
An image processing apparatus for dividing an image signal corresponding to one frame into a plurality of blocks, and performing compression encoding for each block, the image signal being output from a camera unit having focus adjustment means for performing focus adjustment, comprising: a) display means for displaying the image signal; b) designation means for designating a position desired by a user on said display means; c) compression encoding means for weighting the blocks and performing compression encoding therefor in accordance with an output from said designation means; and d) control means for controlling said focus adjustment means in accordance with the desired position designated by said designation means.
Claim 5
Dependent Claim 43 words
Apparatus according to any one of claims 1 to 4, wherein said compression encoding means detects distances between the desired position designated by said designation means and the blocks, and performs weighting processing for the blocks on the basis of the detection result.
Claim 6
Dependent Claim 35 words
Apparatus according to any preceding claim, wherein said compression encoding means includes orthogonal transformation means for performing orthogonal transformation of the image signal, and quantization means for quantizing the image signal having undergone orthogonal transformation.
Claim 7
Dependent Claim 38 words
Apparatus according to claim 6, wherein said compression encoding means weights the blocks by controlling a quantization step of said quantization means with respect to the blocks in accordance with the desired position designated by said designation means.
Claim 8
Dependent Claim 14 words
Apparatus according to claim 7, wherein said orthogonal transformation means is discrete cosine transform.
Claim 9
Dependent Claim 48 words
A camera including image pick-up means, means for detecting the new point of a user of the camera and means for carrying out compression encoding on the image signal generated by the pick-up means in a manner determined by the new point as detected by said detecting means.
