Abstract
Abstract An imaging apparatus for performing efficient signal processing depending on the operational mode. In the finder mode, a CCD interface 21a decimates horizontal components of image data supplied from an image generating unit 10 to one-third and moreover processes the decimated image data with data conversion and resolution conversion to produce Y, Cb and Cr image data which are routed to and written in an image memory 32 over a memory controller 22. In the recording mode, the CCD interface 21a causes the image data from the image generating unit 10 to be written in the image memory 32 via memory controller 22 after decimation and gamma correction etc. The camera DSP 21c reads out the image data via memory controller 22 from the image memory 32 to effect data conversion for writing the resulting data via memory controller 22 in the image memory 32.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
209 words
An imaging apparatus comprising: an imaging section for generating image data based on image light from an object; a memory for storing the image data; a plurality of signal processing sections for performing different predetermined signal processing on the image data; a display for displaying an image corresponding to said image data; a storage section that uses a recording medium for recording the image data thereon; and a controller for performing control in a first and second operation modes, wherein in the first operation mode, (1) decimating the image data generated by the imaging section, (2) processing decimated image data in real-time signal processing sections, (3) storing the decimated and processed image data in the memory, (4) reading-out and displaying the image data stored in the memory, and (5) the real-time signal processing sections being included in the plurality of signal processing sections and performing real-time signal processing; and in the second mode, (a) storing the image data generated by the imaging section in the memory, (b) reading-out the image data stored in the memory, (c) providing read-out image data to the signal processing sections for signal processing, and (d) storing processed image data in the recording medium, (e) the image data stored in the memory being not decimated.

Claim 3
Dependent Claim
74 words
The imaging apparatus according to claim 1 wherein one of the plural signal processing sections comprises resolution conversion means for converting the resolution of the image data; said controller performing control in said second operation mode for reading out the image data from said memory to send the read-out image data to said resolution conversion means and for recording the image data converted in resolution in said resolution conversion means on said recording medium.
Claim 4
Dependent Claim
66 words
The imaging apparatus according to claim 1 wherein one of the plural signal processing sections comprises compression means for compressing the image data; said controller performing control in said second operation mode for reading out the image data from said memory to route the read-out image data to said compression means and for recording the image data compressed by said compression means on said recording medium.
Claim 5
Dependent Claim
29 words
The imaging apparatus according to claim 1 , wherein a resolution of the decimated and processed image data is down-converted before the image data is stored in the memory.
Claim 6
Dependent Claim
30 words
The imaging apparatus according to claim 4 , wherein a resolution of the image data stored in the memory is up-converted before the image data is displayed in the display.
