Digital camera
View Patent ↗A digital camera includes a signal processing circuit. The signal processing circuit makes signal processing on the camera data read from a camera data area of an SDRAM to produce YUV data for record. A thin-out circuit makes a thin-out processing on the recording YUV data to produce YUV data for display. The display YUV data and the recording YUV data thus produced are written respectively to a display data area and a recording data area of the SDRAM and thereafter processed for display on a display and record to a flash memory. The access speed to SDRAM is 48 MHz and the processing speed of the signal processing circuit and thin-out circuit is 12 MHz. Consequently, the YUV data for display and YUV data for record is written concurrently with reading out of the camera data.
1. A digital camera comprising:
a first producer which produces a first recording image having a first resolution on the basis of a raw image of an objective scene captured in response to a capturing instruction, said first producer including a converter which converts said raw image signal into a YUV format, and said first recoding image being of said YUV format;
a second producer which produces a displaying image having a second resolution lower than said first resolution by making a resolution-reducing process on said first recording image;
a third producer which produces a second recording image having a third resolution lower than said second resolution by making a resolution-reducing process on said displaying image, said third producer including a size-reducer which makes a size-reducing process on said displaying image, and said second recording image being a size smaller than a size of said displaying image;
an outputter which outputs to a display monitor said displaying image produced by said second producer; and
a recorder which records to a recording medium said first recording image and said second recording image respectively produced by said first producer and said third producer.
2. A digital camera according to claim 1 , wherein the raw image is an image that each pixel has any one color component.
3. A digital camera according to claim 1 , further comprising:
a first writer which writes said first recording image to a first memory area;
a second writer which writes said second displaying image to a second memory area;
a reader which reads said displaying image stored in said second memory area so as to supply said displaying image to said third producer; and
a third writer which writes said second recording image produced by said third producer to a third memory area.
4. A digital camera according to claim 1 , wherein said second producer carries out a producing process in parallel with a producing process of said first producer, and said third producer carries out a producing process after each of said first producer and said second producer has carried out the producing process.
5. A digital camera according to claim 3 , wherein said second producer carries out a producing process in parallel with a producing process of said first producer, and said third producer carries out a producing process after each of said first producer and said second producer has carried out the producing process.
